Re: [OpenMap Users] UTM to Lat/Lon

Hi Hai,

If you are creating an OMRaster from an image file, the transparency
level won't work. The transparency level only works for images you
create from pixel data.

If you want to change the transparency of an image, you'll have to
change the pixels in it. You can use the
com.bbn.openmap.image.BufferedImageHelper and ImageHelper.getPixels()
method to help you get the image pixels, and then push those into the
OMRaster. The setTransparency() method should work from then on.
