542 Printing from SWF Files
The following list further illustrates the relationship between units of measure.
■ 1 pixel = 20 twips
■ 1 point = 20 twips
■ 72 pixels = 1 inch
■ 72 points = 1 inch
■ 567 twips = 1 cm
■ 1440 twips = 1 inch
To scale a movie clip before printing, set its
MovieClip.xscale and MovieClip.yscale
properties before calling this method, and set them back to their original values afterward. If
you scale a movie clip and also pass a value for the
printArea property, the pixel values passed
to
printArea reflect the original size of the movie clip. That is, if you set a movie clip’s scale
to 50% and specify a print area of 500 x 500 pixels, the content that prints is identical to the
content that would print if you didn’t scale the movie clip; however, it prints at half the size.
For more information, see the
addPage (PrintJob.addPage method) method of the
printjob function in the ActionScript 2.0 Language Reference.
Specifying printing as a vector image or bitmap graphic
The options parameter lets you specify whether to print as a vector graphic or bitmap image.
When using this optional parameter, use the following syntax:
{printAsBitmap:boolean}
The default value is false, which represents a request for vector printing. Remember the
following suggestions when determining which value to use:
■ If the content that you’re printing includes a bitmap image, you should specify that the
print job print as a bitmap to include any transparency and color effects.
■ Conversely, if the content does not include bitmap images, you should specify that the
print job print as vector graphics to take advantage of the higher image quality.
Specifying a frame to print
The frameNum parameter lets you specify a frame to print. If you do not specify a frame
number parameter, the current frame of the target or level specified as the first parameter
when adding a page prints by default.
