PS level restriction patch. (1.12 KB, patch)

Description Behdad Esfahbod 2008-01-15 23:42:31 UTC 
And if unavailable (or generating generic PS), should fall back to level 2 instead of the level 3 as level 3 is not supported by some printers.

PS level restriction patch.

Hi all,
this patch restricts the PS level of generated cairo-surface to the PS level supported by the printer (it gets the information from cups). This sets upper limit of PS level of generated print.
Cairo sets the lowest possible PS level of cairo-surface since version 1.5.6 (mostly to PS level 2). And this patch solves the problem when the required PS level is higher than the PS level supported by the printer.

This patch requires Cairo 1.5.2 or higher (function cairo_ps_surface_restrict_to_level()).

  Regards

    Marek

The patch looks fine to me; we already require cairo 1.5.2 in trunk.
