Transform JPEG data to AFP
This section describes the JPEG to AFP transform and includes its syntax, options, and values.
In this section:
- Syntax
- DescriptionUse the JPEG to AFP transform to transform a JPEG (Joint Photographic Experts Group) data stream into an AFP (MO:DCA-P) data stream.
- Data transformationsIf the input image is gray scale or color, and the output image type is bi-level (for example, IOCA FS10, or IM1), the transform internally scales the image to the desired size, then uses a halftoning algorithm (ordered dither, the default, or Floyd-Steinberg) to convert it to bi-level. In converting the image to bi-level, the characteristics of the output device, such as dot shape and dot gain, must be taken into consideration. The halftone screen and the calibration are extremely printer-dependent. While the transform does contain an internal default (85 LPI screen at 45 degrees), an appropriate screen should be used and the halftone should be calibrated properly for best quality.
