Collection of command-line scripts for image conversions.
These scripts are wrappers for ghostscript, pdflatex, cwebp. Script with names ending in '2' perform two rounds of conversions at single- and double-resolution.
The pdf2png2 and pdf2webp2 scripts are similar. They perform conversions from pdf to other image formats.
./pdf2webp2 figure.pdf
The conversion generates two png files (figure@1x.png and figure@2x.png) and two webp files (figure@1x.webp and figure@2x.webp). The files are single-resolution (1x) and double-resolution (2x) images.
The default single- and double-resolution settings are 150 dpi and 300 dpi. The default webp compression quality is 95. These settings can be changed via environment variables.
dpi=300 cwebp_q=99 ./pdf2webp2 figure.pdf
The tex2webp2 script converts tex content (e.g. equations) to images. The content is expected without tex boilerplate. As an example, a file equation.tex below has three lines which define an equation.
$$
\sum_{n=0}^\infty \frac{1}{n^2} = \frac{\pi^2}{6}
$$
The script converts the tex file into images.
tex2webp2 equation.tex
The conversion produces a pdf, two png files, and two webp files.
