With Canvas X Draw, you can open, modify, and save CGM files created in other applications. CGM file properties, including WebCGM tags are retained, and can be viewed in the Object Properties palette.
Import Background: Imports the background.
Import With Layers: Retains the layers in the file.
CALS Compliant: Retains CALS compliance.
Offset To (0,0): Places the image at the top left of the page.
Retain Bitonal Images: Retain the foreground and background of bitonal images.
Automatic to One Page: Scales the incoming file to fit the page.
%: Select a percentage for scaling the incoming file.
Clip Only If Necessary: This option eliminates clipping rectangles if they do not clip any of the objects assigned to them. Those objects are contained entirely within the clipping area and checking this option will allow Canvas X Draw to redraw much faster; however, if any object stripped of the clipping rectangles is moved outside that area, they will not be clipped because the clipping rectangle has been removed when setting this option. Be careful with this option if you want to move objects in the document.
Hard Clipping: This option eliminates objects that are not visible as a result of clipping.
Render Document: Select this option to change the color mode or resolution of the file.
Color Mode: Select a color mode.
Pixels/in: Select a resolution in pixels per inch.
Import Only Raw Seismic Data: Select this option to import only the seismograph samples. The subsequent trace objects will not have any wiggles or background images, only those samples. Later, using the Seismic Traces palette, you can create wiggles or background image from those samples. If this option is not selected, the wiggles and/or background image will be created on import in accordance to settings included in the CGM file.
Interpolation: Select one of the following:
Collect Lines: Select this option to collect lines.
Skip Degenerate Objects: Select this option to skip degenerate objects.
Canvas X legacy Character Height interpretation
Select this option to maintain character height consistency when opening a CGM file made in a previous version of Canvas.
Click this button to open the CGM Font Matching dialog box. The fonts to be substituted appear in the Original Font column. Select a substitute font from the drop-down list and click OK.
After you have modified the CGM file, you can then export the file. See Working with CGM Files.
