annotate libinterp/corefcn/gl2ps-print.cc @ 29470:2ae4764180c6
Initial implementation of a LaTeX interpreter (bug #59546).
* NEWS: Announce basic support for "latex" interpreter.
* plot.txi: Restructure the "Use of the interpreter Property" section to include
3 subsections, one for each interpreter type. In "Printing and Saving Plots"
describe the new behavior.
* print.m: Document new behavior.
* contributors.in: Add Andrej Lojdl, a former GSoC student that worked on this
subject. Even though there is not much left of his original work, it served
as a very useful starting point.
* base-text-renderer.h, base-text-renderer.cc: New enum to store symbolic
constants for rotation angles.
(base_text_renderer::rotate_pixels): New utility method. Code extracted
from ft_text_renderer::render.
(base_text_renderer::rotation_to_mode): Moved from ft_text_renderer class.
(base_text_renderer::fix_bbox_anchor): New utility method. Code extracted
from ft_text_renderer::text_to_pixels.
* ft_text_renderer.cc (ft_text_renderer::render,
ft_text_renderer::text_to_pixels): Make use of base class utility functions.
* gl2ps-print.cc: New counter variable m_svg_def_index for safe inclusion of
defs coming from dvisvgm.
(gl2ps_renderer::format_svg_element): New function to manipulate svg elements
obtained from dvisvgm so as to position them properly on the figure and
change their color.
(gl2ps_renderer::strlist_to_svg): If the str_list object returned from
text_to_strlist contains an svg element, use format_svg_element to handle
position and color and then return it. Otherwise, use <g> and <text> elements
rather than <text> and <tspan> elements which are not supported by Qt's svg
renderer (svg-tiny implementation).
(gl2ps_renderer::strlist_to_ps): If the str_list object returned from
text_to_strlist contains an svg element, raise a warning about the
necessity of using -svgconvert.
* latex-text-renderer.h, latex-text-renderer.cc: New files to hold the
latex_interpreter class.
* libinterp/corefcn/module.mk: Add new files to the build system.
* text-renderer.h, text-renderer.cc (text_renderer): New data member latex_rep
to hold a pointer to an instance of a latex_renderer.
(text_renderer::~text_renderer, get_extent, set_anti_aliasing, set_font,
set_color, text_to_pixels, text_to_strlist): Duplicate action of the
latex_rep.
(text_renderer::latex_ok): New method to test the usability of the
latex_renderer.
(text_renderer::string::svg_element, text_renderer::string::set_svg_element,
text_renderer::string::get_svg_element): New string data member to hold
preformated svg element. Provide accessor methods.
* acinclude.m4: Add QtSvg to the list of imported QT_MODULES.
* octave-svgconvert.cc: Overhaul program to make use of Qt's QSvgRenderer
when rendering to PDF.
