• Click on the line to select it, then move the Line by dragging the mouse pointer and then release the same at any position on the document.

Note: The operation of stretching of the end points [small white boxes at the end of markups], changing the mark-up shape direction on a single plane and also moving the markups can be achieved on all different types of markups and annotation.

Saving the line markup

After you draw the line markup, click on the [Save] button [highlighted with red rectangle in screenshot below] at the bottom right-hand corner of the screen to save the markup. The Save markup name as pop-up box appears. This is shown below,

• Enter the name of the line markup on this pop-up box and click [Save] button to save the markup

Note: Uncheck the checkbox to make the markup private meaning that it will only be visible to the user who created the markup and not to other users of  the account.

After you save the markup it will appear under the 'Saved markup(s)' drop-down present on the top of the Viewer.

• Click the 'Saved markup(s)' drop-down [highlighted with red rectangle on the screenshot below] to view all the saved markups drawn & saved previously on the document.

• Now, click on the recently drawn & saved markup row [highlighted with green rectangle on the screenshot above] to make the markup annotation shape appear & disappear on the document

Note: This icon [Toggle markup view ON/OFF] means that the markup shape is visible on the Viewer and this icon means that the markup shape is hidden from view. You can click on the saved annotation row to make the markup shape appear and disappear.

• Click [Delete] button to delete the saved markup.

Note: After the markup is saved you cannot change the color, thickness, stretch the lines or move the line or for that matter do anything on the markup except make the markup appear & disappear from the Viewer screen. You can only delete the saved markup from the 'Saved markup(s)' drop-down.

Other markups/annotations are drawn & saved in the Viewer in a similar manner as the 'Line markup'.

• Click the ‘Callout’ icon on the Text menu to draw the callout

• After clicking the ‘Callout’ icon, click on that point of the document from where the arrow head will start (i.e. the position which the arrow head points to), drag the mouse pointer to draw the callout and then after the drawing completes release the mouse pointer to complete the drawing.

As soon as you complete the drawing, the 'Settings' pop-up menu appears on the callout

Screenshot displaying a newly drawn callout with the 'Settings' pop-up menu:

The Callout structure consists of an arrow which points to a piece of text, a symbol or an illustration on the document. The arrow is connected to a rectangle text box within which information regarding that point, to which the arrow points, is entered.

 The Callout Structure Diagrammatic representation:

1. Arrow: The Arrow is the first part of the callout structure. It points to the portion of the document for which information is entered within the rectangular textbox.

2. Connector: The Connector facilitates in the connection between the arrow and the rectangular textbox.

3. Rectangular Textbox: The rectangular textbox consists of the information regarding the point at the tip of the arrow.

Note:

• These three components of the callout structure will not overlap with each other.

• The Arrow & the Connector will have a minimum length beyond which these two component length cannot be reduced. Hence, for best viewing experience a minimum limit on callout arm size has been kept according to current zoom level of document.

Immediately, after the callout structure is drawn, the Callout Settings pop-up box appears. On this pop-up box, you can enter information to be viewable inside the rectangular structure. You can enter text within the pop-up box and these will be automatically visible inside the rectangular textbox.

Screenshot displaying entered text on the callout settings pop-up which gets automatically updated inside the rectangular structure of the callout:

Settings:

• Font color: You can change the font color of the text entered in the rectangular section of the callout. The font color can be red, blue, green, yellow, black or white. Default color is blue.

• Fill color: You can change the fill color of the rectangular section of the callout. The font color can be red, blue, green, yellow, black, white or no color i.e. transparent. Default is no color which is transparent.

• Border thickness: You can change the thickness of the callout border or outline from this drop-down. The minimum thickness is 1 and the maximum is 16. Default thickness is 4.

• Font size: You can change the font size of the text entered in the rectangular section of the callout. The minimum font size is 8 and the maximum is 72. Default font size is 10.

• Border color: You can change the color of the callout border or outline from this drop-down. The border colors can be red, blue, green, yellow, black or white. Default color is red.

• Click [Delete] button to remove the drawn callout

• Click [Ok] button to close the settings drop-down after making any necessary changes.

If by any chance, the size of the text entered exceeds the area of the drawn callout but you click [Ok] button then a message saying “Text entry denied. Reduce size, curtail text or expand area to proceed”.

This means you can reduce the text size, restrict the volume of text entered or expand the size of the callout rectangular area.

After you click the [Ok] button a fully drawn callout becomes visible.

Screenshot below displays a fully drawn callout:

Mobility of the Callout Structure

The Callout structure, both rectangular as well as the arrow portion can be stretched & moved around. The structure shape and arrow length can be changed by moving the white dot, present at the four corners of the rectangle, the connecting point between the rectangle & the arrow as well at the end of the arrow.

The following actions can be performed with the callout structure:

• The rectangular box size can be increased or decreased by dragging any of the white dots at any one end of the rectangle outward & inward, respectively.

• The white dot present at the end of the arrow can be moved around so that the arrow start point can be changed to the mid-point of any of the four sides of the rectangular box. Also, this dot can be moved outward or inward to increase or decrease the arrow length

• The connecting white dot between the rectangular box & the arrow can be moved outward or inward, thereby changing the shape of the arrow. Also, this dot moves along with the white dot present at the end of the arrow.

• Tapping & then dragging the rectangular box outward or inward will increase or decrease the arrow length, respectively. Also, the rectangular box can be rotated around the end-point of the arrow.

Callout Panning

The arrow head will point to the same position on the document when the textbox is move around. For panning users will have to click inside the rectangular text area/textbox and not anywhere within the extended selected area. It may happen that the callout arrow may point to a position which happens to fall within the rectangular textbox area of the callout structure. In this case, for enhanced viewing experience, the callout structure may adjust itself; due to which the callout text box may displace itself out of the purview of the arrow head, however the arrow will be pointing to same position as before.

Note: The saving process is not explained separately for this markup as it is similar to that of 'Line markup'.

Rotation

Please refer to Rotating document pages help file for details.

Calibration annotation

Calibration tool allows the user to create a new calibration line and then based on the length of that calibration line application calculates the length and area of various lines and shapes.

The calibration tool will be used for measuring:

• The length of a line drawn on the document

• he area covered by a rectangular shape

• The area covered by an ellipsoidal shape

• The length of a line drawn in freehand mode

• The area covered by a curve drawn in freehand mode

User first draws a calibration line and enters the length of the line. In reference to the length of the calibration line, application automatically calculates the length and area of various lines and shapes. User must first draw the Calibration line first for the application to calculate the subsequent lengths & areas.

Drawing & calibrating the Calibration line

The Calibration line (Calibration Line) must be drawn first on the document and then the length of the line must be set by the user. Based on the entered length of this Calibration line, the length or area of other lines and shapes will be calculated by the application.

The user first will have to open any PDF document in the SKYSITE F&A Viewer. An opened-up document in the Viewer is shown below,

User will have to click the [Calibration] icon and then click on the [Calibration ruler] icon [highlighted by red rectangle in the screenshot above] on the tool-bar. After clicking the Calibration ruler icon, the user will click on any point in the document and then drag and release the mouse click to draw the calibration ruler. As soon as user draws the calibration ruler line, a pop-up box appears where user will have to select the measurement unit (either in imperial units which is feet and inches or in metric unit which is meters and centimeters).

A newly drawn Calibration line on the document is displayed below,

After selecting the measurement unit user will have to enter the length of the line. For example, user selects the ‘Imperial’ unit of measurement, hence will have to enter the length of the line in feet & inches.

Screenshot below displays the length entered and the Unit of Measurement selected:

Note: The Length textbox only accepts numerical values.

After entering the length measure and selecting the unit of measure the user needs to click on the [Ok] button at the bottom right-hand corner of the Calibration pop-up box.

User can click on [Delete] button to remove the Calibration line. In case of a scenario, when user has already drawn one or more measurement annotations with respect to an existing Calibration line, then once the Calibration line is deleted, all the measurement values associated with the Measurement annotations will turn to zero.

Screenshot below displays a fully drawn Calibration line:

Note:  The calibration line can be stretched outward, dragged inward or rotated around by clicking, selecting and then dragging either one of the two white dots (at each end of the line) across the document. These white Dots are present at both ends of the Calibration line. The calibration line dragged outward or inward, but the calibrated length entered by the user on the Calibration line will remain the same until & unless the user recalibrates the length of the line from the calibrator pop-up box. Also, when the Calibration line is dragged outward or inward, all the measurement values associated with measurement lines and shapes will get updated simultaneously.

After you draw the Calibration line, the measurement line and area drawing annotation icons in the tool-bar will appear activated, while the calibration annotation icon will appear disabled (because it has already been drawn). This is shown below,

Drawing measurement lines & areas

Measurement lines and areas can only be drawn (along with the setting of the length as well as the unit of measurement) after the Calibration line has been drawn.

Line measurement tool

The length of a line will be automatically calculated by the application with respect to the length of the Calibration line. This line can be drawn by clicking the Line Measurement Tool icon and then dragging across the document. The length of the line will be automatically calculated by the application considering the length of the Calibration line. Also, the unit of measurement of the length of the Measurement Line will be similar to that of the Calibration line. After drawing the measurement line, user can click on the line to view the settings of the line.

Screenshot below displays the newly drawn line and its length (along with Settings):

The newly drawn line will have Settings section from where the user can change the color & the thickness of the line.

The application will provide dynamic display of the length of the Measurement Line. This means that as & when the line is stretched outward or stretched inward, the displayed length will adjust itself automatically and will increase or decrease accordingly.

Example: If a Calibration line length has been set at say, 20 inches then the Measurement Line of a similar length (drawn at any angle) will have a displayed length of 20 inch. Now, say the Measurement Line is stretched in such a way, so that its length is doubled. In this case, the displayed length will be 40 inches. Also, as the displayed length of the Measurement Line is dynamic, when user stretches the line, the user will be able to view the change in the displayed length when the line is in the process of being stretched outward.

Also, if the Calibration line is stretched outward or inward, the length of the Calibration line will not change (unless user changes it from Calibration pop-up box) but the length of the measurement line will change.

Screenshot below displays the length of the measurement line calculated based on the length of the Calibration line (2 feet):

The Calibration line is now stretched outward, but user has not changed the length of the Calibration line which remains 2 feet. Hence, the application changes the length of the measurement line accordingly. If the length of the calibration line is increased by stretching the line outward then the length of the measurement line will decrease but if the length of the calibration line is decreased by shrinking the line inward then the length of the measurement line will increase.

Screenshot below displays the length of the measurement line calculated based on the length of the Calibration line stretched outward but the user populated length is kept at 2 feet:

Rectangle measurement tool

The area of a rectangle will be automatically calculated by the application with respect to the length of the Calibration line. The rectangle can be drawn by clicking the Rectangle Measurement Tool icon  and then dragging across the document.  The calculated area will be displayed in the middle of the rectangle. Also, the unit of measurement of the area will be similar to that of the Calibration line.

Screenshot below displays the newly drawn rectangle and its area (with settings):

The newly drawn rectangle will have Settings section from where the user can change the color of the outline border of the rectangle, fill the rectangular area with a color and increase or decrease the thickness of the rectangle border.

The application will provide dynamic display of the area of the Measurement Rectangle. This means that as & when the line is stretched outward or reduced inward, the displayed length will adjust itself automatically and will increase or decrease accordingly.

Circular measurement tool

The area of a circle (ellipse) will be automatically calculated by the application with respect to the length of the calibration line. The circle can be drawn by clicking the Circular Measurement Tool icon  and then dragging across the document.

The application calculates the area falling within the elliptical shape. This calculated area will be displayed in the middle of the circle (ellipse). Also, the unit of measurement of the area will be similar to that of the Calibration line.

Screenshot below displays the newly drawn circle (ellipse) and its area (with settings):

The newly drawn circle or ellipse will have Settings section from where the user can change the color of the outline border of the circle (ellipse), fill the ellipsoidal area with a color and increase or decrease the thickness of the circle (ellipse) border.

The application will provide dynamic display of the area of the Measurement Circle. This means that as & when the circle or ellipse is stretched outward or shrinked inward, the displayed area will adjust itself automatically and will increase or decrease accordingly.

As can be seen from the above screenshot, the ellipsoidal area can be stretched outward or inward by dragging any one of the 8 blue dots present on the four corners and each mid-point of the four sides of the circle (ellipse).

Freehand length measurement tool

The length of an arbitrary line or curve drawn in freehand form will be automatically calculated by the application with respect to the length of the Calibration line. This curve can be drawn by clicking the Freehand Length Measurement Tool icon  and then moving fingers across the document. The length of the curve will be automatically calculated by the application considering the length of the Calibration line. Also, the unit of Measurement of the length of the Measurement Freehand Line will be similar to that of the Calibration line.

Screenshot below displays the newly drawn freehand line (curve) and its length (with settings):

The newly drawn freehand line (curve) will have Settings section from where the user can change the color & the thickness of the line (curve).

The application will provide dynamic display of the length of the measurement freehand line. This means that as & when the freehand line (curve) is drawn outward or inward or drawn around the document, the displayed length will adjust itself automatically and will increase or decrease accordingly.

Freehand area measurement tool

The Freehand Area can be drawn by clicking the Freehand Area Measurement Tool icon  and then dragging across the document.

Example of a drawn Freehand Area:

Procedure for calculating the area of the Freehand Area:

The user can draw any line haphazardly on the document, but the two end points will be connected by a straight line created by the application automatically. This straight line will increase automatically as & when the user draws the freehand line. The area falling within the two lines will also be automatically calculated by the application. Hence, the curve drawn will be automatically closed between the start point and the end point. The area changes automatically and simultaneously with the drawing of the freehand line by the user and the auto creation of the straight line by the application with respect to the freehand line length. This calculated area will be displayed in the middle of the freehand area. Also, the unit of Measurement of the area will be similar to that of the Calibration line.

Screenshot below displays the newly drawn measurement freehand area and its calculated area (with settings):

The newly drawn Measurement Freehand Area will have Settings from where the user can change the color of the outline border of the freehand area, fill the area with a color and increase or decrease the thickness of the freehand area border.

Saving & viewing measurement annotations on documents:

After drawing any of the measurement lengths or areas and performing all the relevant operations on the measurement structure, like, changing the thickness of the border, changing color of the area fill, changing outer border color stretching the structure outward or inward etc. the user can proceed to save the measurement structure.

To save the measurement structure, the user needs to click the [Save] button present at the lower right-hand corner of the Viewer screen. A pop-up viz. Save mark up as will appear asking the user to enter the name of the measurement structure annotation. This is shown in the screenshot below,

The user will have to enter the name of the Measurement Structure in this Save markup as pop-up box and click on [Save]. By default, the annotation created by the user will be public (accessible to all users). Deselect the checkbox to make the annotation private (accessible only to the user who created the annotation).

If user tries to close the Viewer before saving the annotation, then a pop-up will appear asking the user to save the annotation. Once user clicks on [Save], the annotation is saved, again, if user clicks on [Cancel] then the annotation will be cleared or removed.

Note: The user can choose multiple measurement annotations at the same time. Also, the measurement annotation can be saved with other types of annotations markups as well. Again, the user, after drawing the calibration line can save only the calibration line can as a Measurement Annotation.

The saved measurement annotations can be accessed by clicking the [Saved markup(s)] menu button at the top left-hand corner of the Viewer menu-bar. This is shown in the screenshot below,

A drop-down appears which displays all the annotations which have been created and saved on this document (the current file).  The newly saved calibration annotation is, by default, displayed on the document. Each row displays the name of the annotation, the name of the user who created the annotation and the number of annotations that have been saved (Count).

• Click [Toggle markup view ON/OFF] button to make the calibration annotation disappear from the document, hence becomes hidden from user view. This button changes to icon.

• Click button to make the calibration annotation appear again on the document.

User can click the [View all] button to view all the annotations that had been saved on the document.

Scenarios:

Scenario 1: Deletion of Calibration line will set Measurement values of all Measurement annotations to 0 (zero).

Scenario 2: Update of calibration line by dragging a loose end would simultaneously update all Measurement annotations present in document.

Scenario 3: If user clicks the [Create markup] button then the tool-bar reappears and the currently drawn and saved calibration annotation disappears from the document screen.

Saving markups in a group

You can save multiple markups and hyperlinks together in a group. For example, 4 markups and 1 hyperlink is drawn and displayed on the Viewer screen. This is shown below,

• Click [Save] button to save the markups and hyperlinks together.

The Save markup name as pop-up box appears. This pop-up box is shown below,

• Enter the name of the markups & the hyperlink saved together as a group.

• Click [Save] button to save the no. of drawn markups and the hyperlink as a group

After you save the markup group, it will appear under the 'Saved markup(s)' drop-down present on the top of the Viewer.

• Click the 'Saved markup(s)' drop-down [highlighted with red rectangle on the screenshot below] to view all the saved markups drawn & saved previously on the document.

• Now, click on the 'recently drawn & saved markup group' row [highlighted with green rectangle on the screenshot above] to make the markup annotation shape appear & disappear on the document.

• Click [Delete] button to delete the saved markup group.

The hyperlink shape saved with the markup(s) in the group will appear under the 'Saved hyperlink(s)' drop-down. This is shown in screenshot below,

This icon [Toggle markup view ON/OFF] on the 'Saved markup(s)' drop-down means that the markup group shapes are visible on the Viewer and this icon means that the markup group shapes are hidden from view. You can click on the saved annotation row to make the markup group shapes appear and disappear. The [Toggle markup view ON/OFF] icon on the 'Saved hyperlink(s)' drop-down (beside the saved markup group name) will make only the saved hyperlink (saved as part of the group) appear and disappear. This is shown in the screenshot below,

Note: After the markups are saved you cannot change the color, thickness, stretch the lines or move the line or for that matter do anything on the markups except make the markup appear & disappear from the Viewer screen. You can only delete the saved markup from the 'Saved markup(s)' drop-down.
