If I understand what you are attempting, your problem is a misunderstanding of the functionality of opacity. The opacity attribute only applies WITHIN THE IMAGE in GIMP, being used to set the blending characteristics of the layer having the semi-transparent opacity setting with the layers that are beneath it within the GIMP image. Once the image is saved to be used in another application, the opacity attribute is no longer there. When the image was flattened, the layers blended, upon saving to the PNG format, the opacity did its job at that point in order to accomplish the proper blending of the layers to achieve the final image that gets saved out of GIMP. If you must blend the intended background with the image that you wish to be 15% opaque, you will have to do so in GIMP, then import the result of that into scribus. > I've looked to see if I can find a setting to tell an entire layer not > to be completely opaque, but there doesn't seem to be any such > setting. As I recall, scribus has no opacity function. Personally, I don't think it should have one. That should be accomplished in an image processor or a drawing program, not in a page layout program, such as scribus. Page layout is for laying out the elements of the page. Other than typing, those elements should have already been created in another application. Depending on the background you intend to use, one thing you can do is to take the appropriate portion of the background into GIMP for combining with the foreground image, then place the result in scribus on top of the background at the appropriate place on the page. > So I am very confused about the right way to layer a semi-transparent > image on top of a background.
