Attached is the PNG files.
I have stored the PNG files with black background and my custom font in the flash and then utilised:
Setup method
Gpu_CoCmd_FlashHelper_Init(phost);
Gpu_CoCmd_FlashHelper_SwitchFullMode(phost);
Gpu_CoCmd_FlashRead(phost, MEM_FONT_DIGITAL_MEDIUM, 45056, 192);
Gpu_CoCmd_FlashRead(phost, MEM_ICON_GEAR, 45248, 2048);
Render image
Gpu_CoCmd_Dlstart(_phost);
App_WrCoCmd_Buffer(_phost, SCREEN_BG_PRIMARY_COLOR);
App_WrCoCmd_Buffer(_phost, CLEAR(1, 1, 1));
Gpu_CoCmd_SetFont2(_phost, 2, MEM_FONT_DIGITAL_MEDIUM, 1);
Gpu_CoCmd_SetBitmap(_phost, MEM_ICON_GEAR, COMPRESSED_RGBA_ASTC_4x4_KHR, 32, 32);
App_WrCoCmd_Buffer(_phost, BEGIN(BITMAPS));
App_WrCoCmd_Buffer(_phost, VERTEX2F(200 * 16, 135 * 16));
App_WrCoCmd_Buffer(_phost, DISPLAY());
App_Flush_Co_Buffer(_phost);
Gpu_CoCmd_Swap(_phost);
Gpu_Hal_WaitCmdfifo_empty(_phost);
I need to load my custom font to be able to make my black background transparent for my icons.
