PNG with No Alpha Channel?

[Trevor DeVore]

I need to export a PNG image from a Revolution image control that has  
no alpha channel information whatsoever.

The 'export' command seems to always include the alpha channel even if  
there are no transparent areas in the image.

I've also tried loading an image file into an image control an  
transferring the imageData to another image and then storing the text  
of the second image in a file (paintCompression set to "png"). The  
file still appears to have an alpha channel though. qrtPDF says the  
file does and Preview on OS X gives me the option of whether or not to  
include the Alpha channel if I try to export the resulting image from  
Preview.

Anyone know how to produce a PNG without an alpha channel using  
Revolution?

Thanks,
