This is not fully supported in GIMP. The PNG loader seems to handle it nicely, but the GIMP image display has some special code that thresholds the alpha channel for images in indexed mode. This is because the code was written for GIF images. The projection in indexed mode simulates the alpha capabilities of the GIF format, where a pixel is either fully transparent or opaque.

My browser has a white background and, as was suggested in the reply sent to me, I right clicked on the blank page and saved the image to my desktop. I opened the image in Image Viewer and there was a checkered rectangle with a white arrow at the top right corner pointing to the right and another white arrow in the bottom right corner pointing downwards. There is also a pale grey arrow pointing to the right in the top left corner and another similar arrow pointing downwards in the bottom left corner. The 2 grey arrows were not noticeable when the image was opened in Gimp but the checkered rectangle and the white arrows were there.

No you didn't. You got a transparent image with two whit arrows. What colour is your browser background?

[Gimp-user] strange PNG from Adobe Fireworks
Check out this png. I'm not sure if it is editable in the GIMP. http://i34.tinypic.com/rtzshs.png First of all it's an indexed image. You'll see two white arrows on the right hand side. Switch the mode to RGB and you'll see two new alpha transparent arrows appear on the left hand side (!?) Checking the header of the image I see Adobe Fireworks in there. Any ideas what this anomaly of a png is? Eric P. ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
