Fixes #4502. This PR lets you specify fonts (for `IBA::render_text()` or `oiiotool --text`) by family and style name, rather than only by filename of the font file. The implementation is to add `init_font_families()` function, that iterates over the available font files, reads family and style name via the freetype API and caches them. The function is called from `resolve_font()` on demand. Added a new test to the oiiotool-text folder, that loads a font by the name "Droid Serif Bold". --------- Signed-off-by: peter.horvath <[email protected]>

Currently, fonts are identified by the name of the file that defines the font. In Arnold we extended this logic to be able to find fonts based on the font family and style name. This makes it easier for end users to select fonts. For instance "Arial Bold" is defined by arialbd.ttf on Windows. Specifying arialbd is not that obvious and also file names could differ based on the platform.
If you find this useful, we can port our code back here.
I'd also like to point out that it's not that obvious from the current documentation that fontname supposed to be the file name and not the family name.
Specially because some examples suggest the family name should work, like this:
Not sure about other platforms, but for instance on Windows this does not work currently, because "Courier New" is defined by
cour.ttf.The text was updated successfully, but these errors were encountered:
