Gives about 7 % pdftex speed gain when typesetting fiction-type stuff. 2. writet3.c now also with standard /FontMatrix [0.001 0 0 0.001 0 0], tidied up a little (.pgc part untested). No need anymore (hope it's right) to handle PK fonts specially by adv_char_width() in pdftex.web. 3. wrong use of printf() at a few places corrected by Martin. Work in progess, not safe for production. Needs more testing, particularly with PK fonts. Regards, Hartmut ---------------------------------------------------------------------- >Comment By: Hartmut Henkel (hhenkel) Date: 2007-03-04 11:27 Message: Logged In: YES user_id=929 the extended patch 70226a needs more work; removed the patch file. ---------------------------------------------------------------------- Comment By: Hartmut Henkel (hhenkel) Date: 2007-02-25 23:51 Message: Logged In: YES user_id=929 The previous patch 735 is now extended to general text and graphics positioning on the PDF page. pdf_set_origin() (now pdf_move_to()), pdf_set_textmatrix(), and pdf_begin_string() are rewritten. In low placement resolution (e. g. \pdfdecimaldigits=0) now the glyph placement is corrected within the []TJ array by a leading number, like [7(a)...]TJ, if required, so that always full TeX precision is kept (very early pdftex versions might have used this also). Any accumulation of rounding errors should be avoided now by the used calculation principle. Needs lots of testing.
