Sets the depth ( bits per pixel ) of the image stored in Rosetta's memory buffer
Usage:
imgSetDepth (object me, integer newDepth)
Parameters:
newDepth (integer) - the new image depth. Valid values are 1,4,8,24 and 32 bit.
Returns:
(integer) - The success code
Example:
xtRose = xtra("Rosetta").new( )
xtRose.imgOpen( "C:\windows\winnt.bmp" )
xtRose.imgSetDepth( 24 )
Notes:
Internally, Rosetta stores all images in either 1,4,8,24 or 32 bit image. 16 bit depth is not yet supported.
