Hi! This question has been asked in different ways before, but the threads do not seem to give me the answers I need.
We have lots of TB of images with black collars(borders). We would like to try out using Mapserver for serving these images, but we need to have the black collars transparent. That is fine in Mapserver as long at you use regular Tiff. However, because of the many TB of data we need to compress this data and preferably tiff with jpeg compression. However, this compression creates edges between the collar and the image where the image does not get transparent. I am struggling to find a solution to this problem. Is ideas on how we can avoid this problem? Is it for example possible to set a transparency mask in the Tiff image which can be used by Mapserver? Another solution would be if Mapserver could support setting an area in an image transparent based on a polygon file. Any help is appreciated.
