-a {ioca | ioca10 | ioca11 | im1 | ioca42 | ioca45 | PS.2}
-a {IO1_G4 | IM1 | IO1 | IO1_MMR | PSEG_IO1_G4 | PSEG_IM1 | PSEG_IO1 | PSEG_IO1_MMR | OVLY_IO1_G4 | OVLY_IM1 | OVLY_IO1 | OVLY_IO1_MMR | FS45 | FS42 | FS10 | FS11}
Choice of the output image type. The first syntax chooses between the IOCA FS 10 (ioca, ioca10), IOCA FS11 (ioca11), IM1, IOCA FS42 (ioca42), and IOCA FS45 (ioca45) output. IOCA FS10 and IM1 yield bi-level images, while IOCA FS11 results in 4-bit or 8-bit gray or 24-bit color output (see option -outbits). Currently, the only product that supports IOCA FS11 is AFP Workbench. IOCA FS42 can contain either bi-level or 4-bit banded CMYK image at 1-bit per band. IOCA FS45 is a superset of FS42 that also contains 32-bit banded CMYK images, compressed with either JPEG or LZW algorithms. The output compression algorithm is set with the -cmp option. To set the page type (page, overlay, page segment, or object), use the -pagetype option. FS45 produces IOCA FS45 output.
The second syntax is to maintain compatibility with the PostScript to AFP transform, and sets the image type (IO1 for IOCA FS10 or IM1 for IM1 output), compression (G4 for Group 4 or MMR for Group 3), and page type (PSEG for page segment or OVLY for overlay). If you do not specify PSEG or OVLY, the output is a printable page. If you do not specify a compression algorithm, the output is not compressed. You cannot use the second syntax for IOCA FS11 output.
Some older printers do not support IOCA images. In such cases, choose the IM1 output type. IM1 images are uncompressed, and thus, use more space. The processing takes long
