Transform JPEG data to AFP

This section describes the JPEG to AFP transform and includes its syntax, options, and values.

In this section:

  1. Syntax
  2. Description
    Use the JPEG to AFP transform to transform a JPEG (Joint Photographic Experts Group) data stream into an AFP (MO:DCA-P) data stream.
  3. Data transformations
    If 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.
  4. Limitations
    Here are the jpeg2afp limitations:
