The Image is in JPG format now, and has 2128 pixels width, 2832 pixels hight, X-Resolution 72,000 pixels/inch and Y-Resolution 72,000 pixels/inch in the Gimp. The 'Image Resolution' abowe meant that that I must to change in Gimp the Image width to 240 pixels and hight to 320 pixels, right? The 'Image Resolution' has nothing to do with X-Resolution and Y-Resolution, right? Yes How can I know whether the Image has Color Depth 24-bit color? If the item selected in the Image-Mode menu is 'RGB' Any advices will be appreciated! -- Regards, Paul Csanyi http://www.freewebs.com/csanyi-pal/index.htm ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user David ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user

But, in the Channels I can see there Red, Green, Blue and Alfa channel, and in the Title line of the Image window there I can see: ImageName.jpg-5.0 (RGB, 1 layer) 2128x2832. I think that, that this Image is RGB, right? -- Regards, Paul Csanyi http://www.freewebs.com/csanyi-pal/index.htm ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
