Accessing Fonts<br />

Font access for the Library is dependent on both the Adobe PDF Library version <strong>and</strong><br />

the operating system. It is explained in the Adobe PDF Library Overview manual for<br />

all systems other than OS/390.<br />

OS/390 Font Access<br />

For OS/390, the font access method is based on the UNIX method for v1 of the<br />

Library. It will attempt to locate resources via several methods, in this sequence:<br />

1 It will first look for a DD statement named ADOBERES<br />

2 If that is not found, it will look for the PDS member<br />

SYS1.PARMLIB(ADOBERES)<br />

3 If that is not found, it will look for<br />

ADOBE.PDFLIB.RESOURCE.INDEX(ADOBERES).<br />

4 CMAPS are found by looking for<br />

ADOBE.PDFLIB.RESOURCE.INDEX(ADOBECMP).<br />

The ADOBERES listing found at one of those locations is assumed to be a pointer to a<br />

listing of 1 entry: ADOBE.PDFLIB.RESOURCE.INDEX(FONTS). The content of<br />

these files is expected to be encoded using EBCDIC.<br />

The ADOBECMP listing has 1 entry: ADOBE.PDFLIB.RESOURCE.INDEX(CMAPS)<br />

This member contains a lookup table for the CMAP files.

Hooray! Your file is uploaded and ready to be published.
