DARenderPagesToFiles

Direct access, Rendering and printing

Description

Renders pages from an open Direct Access file handle to separate image files without loading the whole document through the normal document model

PageRanges can select non-contiguous pages such as 2,1, 1,4-6, Odd, or Even 2-20. Use an empty string to render every page

If FileName contains %p, that token is replaced with the source page number. If FileName does not contain %p, the source page number is inserted before the file extension
