[OpenLayers-Dev] WMS: jpeg override

[bartvde at osgis.nl]

Hi list,

currently when using a WMS layer as jpeg and transparent true, OL
"automagically" override the image format to png or gif. This has caused
me quite a few headaches in the past weeks to be honest.

I would rather have that transparent true is just ignored, and that the
image format remains jpeg. In the end, this is what a WMS does when it
receives &format=image/jpeg&transparent=TRUE. So why not leave this up to
the WMS to deal with it, and maybe write a warning message to the console
for the app developer in debug mode?

Btw, I am talking about this piece of code:

            // jpegs can never be transparent, so intelligently switch the
            //  format, depending on teh browser's capabilities
            if (this.params.FORMAT == "image/jpeg") {
                this.params.FORMAT = OpenLayers.Util.alphaHack() ?
"image/gif"
                                                                 :
"image/png";
            }

What do others think?

Best regards,
Bart
