Array Containing Font Data for Rendering in OpenGL with stb_truetype

[rjopek]

Hi,

I'm working on a project where I use the stb_truetype library for rendering text in an OpenGL environment. I've encountered a problem related to different methods of loading font data. Here's a detailed description of the situation:

1. Actions Taken:

• I converted the "9x18.ttf" font to a C array using the command xxd -i 9x18.ttf > font_data.c.
• Then, I used the fontData array, which contains the data of "9x18.ttf" font, in my project.

2. Observed Problem:

• When loading the "9x18.ttf" font directly from the .ttf file, the text renders correctly.
• When I use the hard-coded fontData array with "9x18.ttf" data, the text does not display in the window.

3. Technical Details:

• I'm using the stbtt_InitFont and stbtt_BakeFontBitmap functions for font initialization and baking.
  Text rendering is done using stbtt_GetBakedQuad and standard OpenGL calls.

4. Questions:

• Can different methods of loading "9x18.ttf" font data affect rendering in OpenGL?
• Are there any known issues or limitations in the stb_truetype library that might explain this behavior?

5. Additional Information:

• I have checked that the first bytes of the font data are identical in both cases.
• I ensured that stbtt_InitFont returns success in both loading methods.
• I checked the OpenGL settings.

I would appreciate any suggestions or insights that might help me solve this problem.

There shouldn't be anything about stb_truetype (or OpenGL) that would cause this.

i mean, it sounds like formatting, but what is doing the printing and why is it different? these seems very outside the scope of stb_truetype help, though, it sounds like you need help from a general C programming forum or something
