This procedure prints a BMP file stored in flash memory, which was written using TftBmpSdToMem().

The file is referenced by its name and extension from the flash memory.

Example:

TftBmpFromMemName("PIC001.BMP",20,30)

Note: There is no image processing, so the BMP file must meet the following criteria:

• The image must be smaller than the screen's width and height.

• The color depth must be 16-bit RGB (565).

• The row direction should be from bottom to top (default).

• The image should not be compressed.

You can use online tools to convert the file, such as: https://online-converting.com/image/convert2bmp/#.

Select the correct format, upload your image, and download the converted file.

Alternatively, you can use the SdCardWriteRGB565 tool provided in the library.
