It seems that I have three problems: 1. It seems that true color images do not support transparency (even though I'm outputting to a PNG). It does not matter which colour I set to be transparent it always is displayed as black which hides my satellite image. 2a. Because I am now forced to use a paletted image instead of a true color image it seems that the colours in the second image is not added to the palette of the first image. or 2b. The alpha blending on the image causes the actual colours in the top image to be blended with the satellite image. Because of this the top image are blended in with the satellite image. If I do not set imagealphablending ($im, true) then the transparency in the top image is ignored and I do not see the satellite image. This brings me back to the original problem: I have a true colour satellite image in PNG format. On top of this I want to add the data collected from data collected by my company. This is always shapes drawn which should not be alpha blended with the satellite image. These shapes are drawn on a transparent background. The transparent background allows for the satellite image to show through. Any suggestions are welcome. Albert -- No virus found in this outgoing message. Checked by AVG Free Edition.
