ImGui + FontAwesome Example

How to Update Font Files

  1. Download from webfonts FontAwesome .tff file
  2. Download (or generate) updated headers from IconFontCppHeaders
  3. Convert .tff file to byte array
  4. Replace template example files

How to convert .tff to header file

  1. Download binary_to_compressed_c and compile following file comments (or use precompiled version from release)
  2. Run generated executable with fonts in same folder that executable using following parameters: binary_to_compressed_c.exe fa-solid-900.ttf FontAwesome > fa.h
  3. Finished

Additional Information

  1. You can use brands icons following the same steps but using Brands fonts
  2. To use multiple icon sizes you'll need add create multiple versions in memory like:
io.Fonts->AddFontFromMemoryCompressedTTF(FA_compressed_data, FA_compressed_size, 12.0f, &icons_config, icons_ranges);
io.Fonts->AddFontFromMemoryCompressedTTF(FA_compressed_data, FA_compressed_size, 20.0f, &icons_config, icons_ranges);
  1. If a quotation mark is displayed instead of the icon, probably the Icon header and Font Awesome version are not the same

Performance Implications:

I had some issues with performance degradation when using custom icons in a extreme low-end hardware (in a application with a HUGE iterations per second)
