font creation #51

Open enemykrs opened 4 years ago

enemykrs commented 4 years ago

hi, is there a manual or tool for creating a font? I need to add the Cyrillic alphabet, but I can’t understand how

Martin-Laclaustra commented 4 years ago

I am writing a converter for psf files. Until I release it and I make a pull request... are these files useful? cp866.zip Can you please confirm that they work?

enemykrs commented 4 years ago

thanks, but these files do not have the characters I need I’ve already figured out how to draw a font and added the letters I need but, if I understood correctly, the width of the letter is fixed and, for example, the signs "." and "W" have the same width, which leads to uneven gaps between characters

Martin-Laclaustra commented 4 years ago

Is there any official codepage that contains the characters you need? 855? Any one in: "/usr/share/consolefonts"? All the fonts in this engine are fixed-width. For other needs use fonts through the Adafruit engine instead. See the "GFXWrapper.ino" example.

codepage KOI8-R

the example "GFXWrapper.ino" ended with a compilation error I did not understand the reason `In file included from C:\Users\Admin\Documents\Arduino\libraries\bitluni_ESP32Lib\examples\GFXWrapper\GFXWrapper.ino:7:0:

EDIT: This is not the solution. Try the one in the post below... Try to move lines 19 and 20 in GfxWrapper.h https://github.com/bitluni/ESP32Lib/blob/8f4b1bc9c331546c57c1ee837ac37303b8d8739c/src/GfxWrapper.h#L19

to line 26.

Please report if this change succeeds because we should write a pull request in that case.

Please tell me if this font renders correctly, and if it is the one you needed. koi8_r_8x16.h.zip

EDIT: I still found problems with this. An error in the converter added extra 8 bytes upfront (now is fixed in the file in this post) and the source font map is not the standard one.

After some thought, this may be the solution: Change lines 22 and 23 in GfxWrapper.h https://github.com/bitluni/ESP32Lib/blob/8f4b1bc9c331546c57c1ee837ac37303b8d8739c/src/GfxWrapper.h#L22 https://github.com/bitluni/ESP32Lib/blob/8f4b1bc9c331546c57c1ee837ac37303b8d8739c/src/GfxWrapper.h#L23

to this:

        :Adafruit_GFX(xres, yres),
        base(vga)

Please report if this change succeeds because we should write a pull request in that case.

Now the source files for these I believe had the correct character maps: koi8-r-8x8-8x14-8x16-fnt.zip

enemykrs commented 3 years ago

fonts did not fit, but your tip on how to start GfxWrapper helped, thanks took your martin-laclaustra_ESP32Lib-advanced and in 1bitmode everything works

pierreH23 commented 3 years ago

Hello, Hope it helps : I managed to create new fonts with TTF2BMH (https://github.com/jdmorise/TTF2BMH) ! Now, my recipe for a font.ttf :

Regards Pierre

Martin-Laclaustra commented 3 years ago

Thank you! We will test it.
