Hello all, I've encountered a strange issue (running 5.0) that I couldn't find any references to in the Help or online documentation. I'm importing tiny monochrome bitmap files into Mathematica, in order to create a pattern that tiles the black-pixel pattern in x and y repeatedly. I can import the file correctly (I've checked with the Dimensions function and everything works properly), but when I use the Show command to check that I've got the right bitmap, I don't see the proper image. I tested it by creating a 1-white-pixel-wide buffer around the original image, and then I saw the correct original image with the Show command. So it appears that the Show command is somehow cropping the image by 1 pixel (for images smaller than 10x10 pixels). I suppose I could just design all my bitmaps with an extra pixel buffer, but that's much less elegant. Does anyone know why this is happening? Appreciating any help, Matthew
