bmpfile	In	String	required	The path of the picture file.

Returns: 1 if the picture was loaded, otherwise 0.

Description

Loads a picture file into a buffer, stretched to cover all of it. Returns whether the file could be loaded.

• Formats other than BMP load as well, but not JPEG 2000 or TIFF with Deflate or JPEG compression, see Image formats. The picture is always scaled to the size of the buffer, with smooth filtering.
