Defining 2D Page Layout Settings
The page and format settings can be set up in the Format Parameters section under the Page Layout tab. Using the options available in this section, you can select page format, page width, page height and margins.
NOTE: All layout parameters are specified in units of typesetting "point", or "pt". A pt unit is 1/72 inches, or 0.35277mm. Accordingly, A4 page size is 595 x 842 pts, while Letter format is 612 x 792 pts. The menu is provided to show page size in any of these units.
To Define Page Settings:
- Click on the Page Layout settings tab.
- Go to the Format Parameters section which is the first section under the Page Layout tab.
- In the Format field, select the paper format from the drop-down list of available paper formats. Select the Landscape checkbox if the format should be in landscape mode.
- In the Page Width field,the values are displayed based on the page format selected. You can only adjust the page width when the Custom option is selected in the Format field. Use the arrow buttons to scroll up or down till you reach the desired page width.
- In the Page Height field,the values are displayed based on the page format selected. You can only adjust the page height when the Custom option is selected in the Format field. Use the arrow buttons to scroll up or down till you reach the desired page height.
Note: According to the ISO 32000 (PDF) specification, page size shall not be less than 3 or greater than 14400 units (pts) in either direction.
- In the Left Margin, Right Margin, Top Margin and Bottom Margin fields, use the arrow buttons to scroll up or down till you reach the desired margins. These define the position of the 3D view, relative to the page border.
- Once you select the Format Parameters, the next step is to define the Image Parameters.
Note page layout can also be pre-specified in a template PDF, where by using Merge Modes an existing dummy 3D view can be replaced, or the target view layout can be specified using a place-holder layout.
Legend Bar Placement
In some operation which include the generation of a legend bar, such as appying a colormap to elevation terrain models, the legend is automatically placed on the page in a default layout. To allow more precise positioning, explicit layout parameters can be enabled.
In the Position LeftPosition Right, Width and Height fields, the legend bar with text labels and title can be placed, relative to the page border.
In case the legend is not needed, it can be disabled using the Legend Visible checkbox.
