RIF-Request Image File
Allows an image file to be returned from the internal still image folder on the Spyder system. Image files
are always normalized to a .PNG format, regardless of their original format. The dimensions of the image
may additionally be downscaled to a specified maximum width or height.
Note:
The byte formatting returned from this command is an ASCII encoding of hexadecimal numbers.
For example, the following four bytes ‘0x00 0xAB 0xAC 0xFF’ would be returned as the string literal
‘00ABACFF’.
Note:
This command should be used sparingly, and it is recommended that the client device cache
images locally to avoid regular re-downloading when possible. Heavy use of this command, particularly
when image scaling is in use, may have a performance effect on the Spyder server.
