Hi Richard, You are welcome! :D I have added more information about the BMP3 Header in this attached text document. - BMP3 Header explained - This header allows to export Livecode Raw Imagedata as a BMP3 file: 32 bits BMP with an alpha channel. Only 12 bytes are changed: - 4 bytes - Size of the BMP ...
Using this crafted bmp header, you could export the imagedata of any Livecode image without loss (JPG) or compression (PNG). This format is useful for working with exact 8 bits RGB colors.
I will use this for calculating the negative height of BMP files. https://stackoverflow.com/questions/37368273/how-to-set-an-negative-value-to-the-resolution-of-a-bmp-image-in-hex Mac OSX Preview and GIMP opens fine these BMP with Transparency and negative Height. https://drive.google.com/file/d/1Xi...
