[MS4W-Users] Image 24 Bit

[José Pedro Santos]

Dear all, 

I'm attempting to classify images of 24 bits but I always have the error saying this: ........Unable to access file. Attempt to classify 24bit image, this is unsupported.

My Mapfile is this one: 

...........

IMAGETYPE "png24"

..........

OUTPUTFORMAT # Parameter Output
 NAME png24
 DRIVER "GD/PNG"
 MIMETYPE "image/png"
 EXTENSION PNG
 IMAGEMODE RGBA
 TRANSPARENT ON
END # end of parameter Output


and in the expression of GetMap I use FORMAT=image/png

In the Layer description I have the special processing directives to processed the 3 bands. But If put just 2 appear one empty image not the error. I already read some documentation but I can't succeed. 

any idea?

Many thanks and best regards,

José Santos
