Script for converting BMP to BIN for RGUI Fonts

rtomasa commented 2 years ago

Is it feasible to get the script or a brief explanation on how to convert the font spritesheet bitmap.bmp to bitmap.bin? I'd like to create a custom one and be able to compile in RA

I presume this is a reference to the RGUI Fonts? If so, it looks like @DisasterMo, @trngaje and @jdgleaver are likely the experts on this issue. If it's referring to something else in the repository, let us know.

Sorry, yes I was doing reference to RGUI Fonts

@DisasterMo, @trngaje, @jdgleaver Any possibility to get that script or some details on how to generate the bin files?

trngaje commented 2 years ago

There is no source for reference because it is reconstructed with simple c code depending on the type of input font.

cjk fonts are generated by .ttf and modified pixels by manual.
extended english font are generated by png font image. I thought about organizing it once, but i coudn't because the font distributed in each language is different, Which font do you want to change to bin? font type (bmp, png, ttf, bdf ...). and char sets. Please give me specific information. I can create tools and distribute sources based on specific font data, but I can't unify them for all languages. Most of the codes are implemented by reverse engineering of the retroarch font output part, so the codes are the same

@trngaje I'm only interested in the RGUI bitmap .BMP fonts. Maybe my understanding on how it works is not correct. I saw the sprite-sheet font.bmp in the corresponding RetroArch folder and also a font.bin file that I assumed that corresponds to the binary encoded file (assumed that you create the font.bin from font.bmp using some script). Also assumed that when compiling RA, make command will take the bin file to "generate" the font inside the C code. Maybe I'm completely wrong...

@trngaje I've finished creating and compiling my first custom font in RA and everything worked perfectly fine but the switch icons and the current selected value option indicator that display garbage. Do you know if this is something independent from the font sheet? EDIT: OK I found out that all symbol icons are hardcoded in rgui.c so now I can also customise their widths independently
