printAsBitmap( ) Global Function
Flash 5
print the frames of a movie or movie clip as bitmaps
printAsBitmap(target, boundingBox)
Arguments
target
A string or reference indicating the path to the movie clip or document level to print (references are converted to paths when used in a string context).
boundingBox
A string either "bframe", "bmax", or "bmovie" indicating how the printed frames of target should be cropped or scaled when printed, as described earlier under print( ).
Description
The printAsBitmap( ) function is functionally identical to print( ), except that it outputs rasterized content to the printer, not vectors. Therefore, it can successfully print movies with alpha channels and color transformations, but it produces poorer quality for vector-based artwork.
