In many respects I think it probably *is* the expected thing, but some users are suggesting our app may be at fault because the image size they get isn't what they expected. There's no doubt about it being what has been done historically, but now that pixels are becoming somewhat divorced from image dimensions, it could be time for a change. Our app can export images at pretty much any size and dpi, no matter what the size of the source image. The dpi and scale factors are used to figure out how many pixels that is, and we render to a bitmap of that size and write it out in the desired format, setting the dpi metadata correctly. The trouble is, that if we told the user we're exporting a 128 x 128 image at 144dpi, but then the Finder goes and displays that file with a 256 x 256 dimension, the user thinks we made a mistake and our export feature is faulty. Maybe more education is needed but we thought we had explained all that. Maybe we need to display the calculated pixel sizes up front so the user doesn't get surprised by the outcome. > Anyway, while the usage you hope for is understandable, so is Apple's choice > not to change it.
