%: Select a percentage for scaling the incoming file.
Object Clipping 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 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 Options 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.
Seismic Options 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:
Default: Defined in PIP file.
Off Always: No color interpolation.
1D Always: Displays the background in baseline direction only.
2D Always: Displays the lines in biaxial interpolation.
