Data transformations
For very light or very dark images, the halftoning algorithms can be automatically recalibrated to preserve details that would be lost using the default calibration. See the -alg option for more information.
To maintain the image quality, scaling must be done before halftoning. The halftoning algorithm is very computation-intensive. Unless the images are small, GIF to AFP cannot process the color images fast enough to feed even a slow printer.
The size and position of the output image depend on several factors:
- The size specified to the transform
- The form map specified at print time
- The forms and options loaded in the printer
If the image is too large to fit on the page, it is trimmed to size by default. Use the -fit scale option to tell the printer to scale the image to the paper size. If you do not specify the paper size with the -paper option, the paper size defaults to US letter size (8.5 by 11 inches). If the image is larger than this, the paper dimensions are increased as necessary. If the paper size is specified explicitly, it is not increased if the image does not fit on paper. The options -l and -w have the same effect as -paper.
The size of the actual image (as opposed to the paper size) is controlled by the -scale option. You can either specify a v
