Feature request: loading fonts from SPIFFS/LittleFS

[marcelstoer]

Maybe I didn't quite get it yet but from what I understand OpenFontRender can only load fonts from SD card or binary (i.e. embedded in code).

Working with ESP32 it would be most helpful to be able to load fonts from the internal LittleFS file system.

Hello I have same understanding and need. Loading from LittleFS Thanks!

[infrafast]

Here is the code I've used:

  // Open the font file
  File fontFile = LittleFS.open("/myfont.ttf", "r");
  if (!fontFile) {
    DEBUG_PRINT("Failed to open icon file");
  }

  // Read font file contents into a buffer
  size_t fileSize = fontFile.size();
  uint8_t* fontBuffer = (uint8_t*)malloc(fileSize);
  fontFile.read(fontBuffer, fileSize);
  fontFile.close();
  if (iconOfr.loadFont(fontBuffer, fileSize)) { 
    DEBUG_PRINT("\nIcon Initialise error"); 
  }

hope this helps

OpenFontRender v1.2 now includes enhanced support for file systems.
Font loading from SPIFFS is also supported and can be enabled simply by using a preset.
Unfortunately, no LittleFS presets are provided yet, but it should be possible to support the LittleFS file system by implementing custom code.
Please see document and sample code for more info.
Welcome your feedback.

Sorry for the crazy slow response.

Hi thanks a lot, I suggest you enapsulate the code I provided for littleFS in a method of your class then
