Fit to Screen
Fits the image to your screen. If you select Use Image Aspect Ratio, the program
fits the larger dimension to the screen while maintaining the image’s aspect
ratio.
Use Image Aspect Ratio
Uses the aspect ratio of the image file. You can still change Offset and Scale,
but the Maintain Aspect Ratio option is locked to the On setting.
Tiling
Controls how the bitmap is tiled with two radio buttons.
Crop
Does not tile the bitmap.
Tile
Tiles the bitmap (the default).
If you select Tile and you change the offset so the bitmap rectangle appears
outside the projection rectangle, the bitmap is not centered within the drawing
area when you render it. (During tiling, the offset acts as a displacement, not
an absolute position.) However, if you select Crop, the bitmap is rendered
only where you place it, as indicated by the diagram (enclosed by the inner
box labeled Scale) in the Adjust Background Bitmap Placement dialog box. If
the diagram shows the bitmap outside the projection rectangle, the bitmap
does not appear in a rendering.
Center
Sets the Offset coordinates to 0 (centers the image).
BACTION
Adds an action to a dynamic block definition
Block Editor toolbar:
Command line: bedit

baction
You can only use the BACTION command in the “Block Editor” on page 139.
Actions define how the geometry of a dynamic block reference will move or
