Firstly to emit the name as part of the font comment, secondly to - put the name as the value for the /FontName key in the fotn dictionary. In - the first case we write it as a simple string, in the second as a name. + The new code delays the execution of idle masks + after all containing groups are executed, + so that the queue is now longer and stores all masks. + We beleive that's not harmful, because + transparency queue elements are pretty small and + work for hos based applications only. -3. (opdfread.ps) The TypeDameons procedure extracts the FontName from the Font - dictionary in the body of the job. Since the FontName can now be escaped, - we need to undo the escapement before defining the font. Firstly we define - a new procedure 'UnPDFEscape', secondly we call this when dealing with the - FontName and the BaseFont keys, in order to convert the escaped name back - to a normal name, so that the font can be found with findfont. + The new function mark_as_idle works for the new logic. + Few aother functions are enhanced with a smarter + processing of the idle flag. +5.

See also item 11. +This really skips compositors which don't paint anything. -4. (gdevpdfx.h) Add a new member 'last_charpath_op' to the gx_device_pdf_s structure, to - hold the boolean argument associated with a charpath operation. Also add to the - pdf_substream_s structure to allow us to save and restore this value on entry to or - exit from a PDF substream. +Compositor parameter list structures are extended with a new boolean field 'idle'. +These fields pass information whether something was painted to a compositor. +We choosen this way for passing this info because +(1) we can't change the device inteface with new function arguments, and +(2) we need to pass it through the device chain +(for example, when a clipper is installed onth the overprint device). -5.

(gdevpdfx.h) Add a new member variable 'last_charpath_op' to the 'pdf_substream_save_s' - structure to allow us to save and restore the last_charpath_op as noted above. +This patch does not fix the bug 689492. +That fix may be done either before or after this one, +but in any case the patches need to adopt each to another. -7. (gdevpdtt.c) During gdev_pdf_text_begin, if the operation is a charpath, check the - following conditions, if met then store a copy of the charpath boolean variable in - a new member of the gx_device_pdf_s structure. - 1. Operation must be a charpath - 2. Current path must be empty (can't handle charpath concatenated to existing path) - 3. The font being used for the current text must be the same as the font used for - the previous stored (but not yet emitted) text. - 4. The initial point of the text for the charpath must match the initial point of - the previous stored text. - 5. The text bytes must be the same as the previous stored text. - 6. The point size of the text must match the previous stored text. - Also, move the calculation of the font point size out of pdf_update_text_state so that - we can calculate the size in pdf_compare_text_state_for_charpath' defined in 9 below - without duplicating code. +The new compositor virtual method is_closing +checks whether a current compositor command +closes an older command, and finds the opening command. +Now we provide untrivial implementations for transparency and overprint compositors. +Would like to define an enum for return values of is_closing. -8. (gdevpdtt.h) Prototype 'pdf_calculate_text_size' +The old device method create_compositor now passes the 'idle' parameter via +gs_composite_s structure. By default it is false and the behaviour +is same as before. But the clist interpreter is modified +to provide true value when a compositor doesn't paint anything. +To compute this flag the compositor queue now works with its full power. +Note we changed the queue representation with a bilikned list. -9. (gdevpdts.c) Add a new function 'pdf_compare_text_state_for_charpath' to do the - checking noted above. The pdf_text_state_s structure is not defined publicly, so - we need code to access its members. Also add a function 'pdf_modify_text_render_mode' - which will attempt to add a rendering mode (stroke, fill or clip) to existing text - by updating the existing text rendering mode. Returns 0 if the existing text cannot - be modified, and we fall back to emitting a path and stroke. +This patch entroduces the concept of 'friendly operations' +for compositor operations. These are those operations, which +may interchange with compositor installation/deinstallation. +One example is halftone operations, which always affect +the device below the compositor device, i.e. the target device +of the compositor device. The new compositor virtual method +is_friendly is implemented in an intrivial way for the +transparency compositor especially to exchange with halftone +operations while queueing clist operations. +This especially helps to delay the pdf14 device installation +so that it may completely annihilate with its deinstallation +if nothing is painted through the compositor in a band. -10. (gdevpdts.h) Add prototypes for the functions required in 9. +Overprint and transparency compositor implementations +are changed with checking the idle flag. +If it is set, they don't perform neither color blending, nor +raster buffer allocation. Note the pdf14 device maintains the buffer stack +as before, but the allocation of buffers may be skipped. +It saves significant time from cleaning up raster buffers when they are idle. -11. (gdevpdfd.c) In pdf_stroke_path, if the 'last_charpath_op' member of the pdf device - structure is set, perform some more checks (below) and if passed, set the text render - mode of the stored text, set the stroke colour, set the line width, and force the stored - text to be emitted. This conveniently results in a gsave/grestore pair round the - graphics state changes. - 1. The last charpath operation must have been 'false charpath' - 2. There must be a non-empty path (result of the charpath operation) - 3. The 'last_charpath_segment' stored in the path must match the actual last segment - in the path. (can't handle path segments added to the result of a charpath) +This patch may need further improvements for the case when +different compositor types are mixed in one queue. +We could not fully test it due to absence of practical tests. -12. (gdevpdfg.h) Make the pdf_reset_color routine public, as we need to be able to set the - colour from pdf_stroke_path. +Another useful improvement would be to convert +"0 .inittransparencymask 1 .inittransparencymask dict .setblendparams" +into a single command. It would simplify the compositor queue logic. +Also we think that the name .inittransparencymask doesn't reflect the function purpose. +Will improve someday. -13. (gddevpdfg.c) We need to be able to set a stroke colour while in a TEXT context, - previously the routine pdf_reset_color, which emits colours and spaces, immediately - switched to a STREAM context, which caused pending text to be flushed. pdf_reset_color - was only called from two places, pdf_set_drawing_color and pdf_set_pure_color. The - switch to a STREAM context has been moved to these routines, leaving pdf_reset_color to - actually do the work without worrying about the context. - It was found necessary to also reproduce some checks before switching context, to - prevent unnecessary context switches. - Removed unused local variable 'process_color' from pdf_reset_color. +We're not sure whether this patch correctly works with idle masks. +We could not debug it due to no practical cases. +Possibly idle mask will need an additional effort to skip +the group painting to the band. -There is scope for additional enhancement with this code. Presently there is no attempt to -deal with 'charpath gsave fill grestore stroke' constructs, nor to handle clipping paths -resulting from charpath.

NB it is not -possible, in PDF, to construct a type 0 font with anything other than CIDFonts as -descendants, and we must therefore output one or more type 1 fonts to do the job. - -1. (gdevpdtt.c) in scan_cmap_text add a case to handle a type 1 descendant font. The main - work is done in this routine; we create a list of glyph name indices representing - each of the input character codes and later we use pdf_obtain_font_resource_unencoded - and the TEXT_FROM_GLYPHS operation to mark the font usage, and create an 'encoded' - string for output. - - If font->procs.next_char_glyph returns a glyph name index, then we simply add it to - our list, if it returns a character code (a CMap can map a character code in the type - 0 font to a character code in a descendant font) then we use the descendant font - 'procs.encode_char' to get a glyph. - - Once we have a complete list of glyphs, we pass it to - pdf_obtain_font_resource_unencoded to add the glyphs to the encoding, and return a - string where the character codes match the newly created/modified encoding. - - Finally we pass the encoded string and glyph list to process_text_modify_width, using - the descendant font. +Fix (jbig2dec): The global data stream for a JBIG2 image in a PDF +file was being released, and the data freed by the garbage collector, +before the data was used. - A couple of minor points; its possible to change descendant fonts in the middle of a - string, and we need to cope with that, hence the copying of the last glyph in the list - when a font_change occurs.

The function reserve_char_code_in_pdfont was written to handle single glyphs, it can - now be called with multiple glyphs. The loop for re-using positions in the encoding - with /.notdef codes didn't use the 'last_reserved_char' argument, which meant that it - kept returning the same position. To prevent this it now pays attention to the - 'last_reserved_char' argument. - -5. Finally, the routine pdf_make_text_glyphs_table_unencoded, which calls - reserve_char_code_in_pdfont also did not previously expect to be called with multiple - glyphs.

But this method - cannot work when fonts are not embedded: cannot "normalize" - something stored in an external file. - - part #2: PDF interpreter fixes (pdf_font.ps, pdf_ops.ps) : - -- Force the "wy" parameter of "d0", not only of "d1", in Type 3 - charproc streams to 0. Comment changed to suggest this is an action - is expected to be done as part of enforcing the metrics stored in - the PDF (which always imply wy == 0), and not some strange - behaviour in Reader. - -- A detail in PDF1.7 Ref 5.3.3 "Text Space Details" states that "wy" - (or "wx" in WMode 1) must be forced to 0 in PDF text space too, not - only in PDF glyph space. To implement this with non-[s 0 0 s tx ty] - font matrices, a different method is used: decode "show" strings - and extract glyph widths with "cshow", put these into an array, - then render the text with "x/yshow". - - since "wy/x" = 0 in glyph space, the code does not need to use - "idtransform", a "div" by "FontMatrix.xx" is sufficient; - - use a trick (see comment in code) when "FontMatrix.xx" = 0. - -CIDFonts are not changed.

By default it is false and the behaviour +is same as before. But the clist interpreter is modified +to provide true value when a compositor doesn't paint anything. +To compute this flag the compositor queue now works with its full power. +Note we changed the queue representation with a bilikned list. + +This patch entroduces the concept of 'friendly operations' +for compositor operations. These are those operations, which +may interchange with compositor installation/deinstallation. +One example is halftone operations, which always affect +the device below the compositor device, i.e. the target device +of the compositor device. The new compositor virtual method +is_friendly is implemented in an intrivial way for the +transparency compositor especially to exchange with halftone +operations while queueing clist operations. +This especially helps to delay the pdf14 device installation +so that it may completely annihilate with its deinstallation +if nothing is painted through the compositor in a band. + +Overprint and transparency compositor implementations +are changed with checking the idle flag. +If it is set, they don't perform neither color blending, nor +raster buffer allocation. Note the pdf14 device maintains the buffer stack +as before, but the allocation of buffers may be skipped. +It saves significant time from cleaning up raster buffers when they are idle. + +This patch may need further improvements for the case when +different compositor types are mixed in one queue. +We could not fully test it due to absence of practical tests. + +Another useful improvement would be to convert +"0 .inittransparencymask 1 .inittransparencymask dict .setblendparams" +into a single command. It would simplify the compositor queue logic. +Also we think that the name .inittransparencymask doesn't reflect the function purpose. +Will improve someday. + +We're not sure whether this patch correctly works with idle masks. +We could not debug it due to no practical cases. +Possibly idle mask will need an additional effort to skip +the group painting to the band. + +Also disabled cmd_put_halftone in c_pdf14trans_clist_write_update - +see comment in code. + +Monor change : Inserted a visual trace support for transparency buffers. + +</pre> +<p>[src/lib.mak src/zdict.c src/gdevdflt.c src/gdevp14.h src/gstrans.c src/gsalphac.c src/gxcomp.h src/gsovrc.c src/gstparam.h src/gstrans.h src/gxclrast.c src/gsovrc.h src/gdevp14.c]</p> +</blockquote> + +<p><strong><a name="2008-01-09T003630.938192Z"></a> +2008-01-09T00:36:30.938192Z Marcos Woehrmann</strong></p> +<blockquote> +<pre> +Fixed umlauts (maybe, am having trouble testing the results). +</pre> +<p>[man/de/pdf2dsc.1]</p> +</blockquote> + +<p><strong><a name="2008-01-09T002450.313955Z"></a> +2008-01-09T00:24:50.313955Z Marcos Woehrmann</strong></p> +<blockquote> +<pre> +Corrected man page (thanks to Peter Dyballa). +</pre> +<p>[man/de/pdf2dsc.1]</p> +</blockquote> + +<p><strong><a name="2008-01-09T000059.719986Z"></a> +2008-01-09T00:00:59.719986Z Alex Cherepanov</strong></p> +<blockquote> +<pre> +Add unmodified byte-oriented AES encryption code by Brian Gladman.
