Migrate ipptransform to this project #65

Closed michaelrsweet closed 1 year ago

michaelrsweet commented 1 year ago

The ippsample project currently hosts the ipptransform tool, but it belongs in this project so it can be more widely used.

Initial check-in, still need to do localization and add PostScript (bitmap) output.

Very nice! This makes my "pdf2printable" all but redundant (and that's a good thing). Especially impressive that you could get mixed-orientation PDFs to come out usable from pdftoppm.

It seems you made a copy-paste error in the ps_end_page code (real version left uncommitted?); it looks very much like just another pcl_end_page. If i replace it with a single "showpage" it comes out rotated, so presumably it needs something more.

(And the psstart* refer to PCL in their comments).

@attah Yes, what is in the repo is an incomplete work-in-progress. Ultimately this program is what will get used to convert print files into something a printer will accept for the local and sharing servers, as well as doing some of the higher-level manipulation/scaling/imposition functions. The output formats are intentionally limited but we'll need PCL and PostScript support for printing to legacy Windows print servers.
