This page shows how to convert a LaTeX document x.tex into a PNG image.
When converting vector graphics to bitmap images (like PNG) you have to specify a resolution. This is the number of pixels per inch.
gxhconvert -o=png -r=_resolution_ x.tex
See the [gxhconvert manual] for a full description of the gxhconvert script.
Option | Purpose |
---|---|
-a --alpha |
Create alpha channel. Untouched input regions result in transparent output regions. |
--interlaced | Create interlaced PNG. The start of the file (data stream) allows to render the image in low quality, details for better quality follow. |
--optimized | Optimize (decrease) file size. Computation takes a little longer and uses more memory. |
--ultra-optimized | PNG file size optimization, do exhaustive search with large number of trials using optipng options "-zc8-9 -zm1-9 -zs0-3 -f0-5" |
--web | Shortcut for "--interlaced --optimized --ultra-optimized". |
pdflatex -interaction=nonstopmode x pdf2svg x.pdf x.svg inkscape --batch-process --export-type=png --export-overwrite --export-filename=x.png --export-dpi=_resolution_ --export-area-page x.svg
pdflatex -interaction=nonstopmode x pdftoppm -r _resolution_ x.pdf | pnmtopng > x.png
