Red Blue Anaglyph ComputationRed/Blue anaglyphs are a simple and computationally inexpensive method forquickly evaluating the photogrammatic potential of stereo images. Such imagesare available as stereo pairs from ASTER, MISR, WorldView2 and otherplatforms that capture off-nadir images. Choose ‘Post Process | ‘CreateAnaglyph’ and then choose the type of anaglyph you want to compute. Note thatboth the left and right stereo images must be exactly the same size.215
Grayscale and Color Image TilingIt may sometimes be advantageous to save processed grayscale or color imagesas tiles rather than a single image. PANCROMA offers a post processing utilitythat decomposes a single image into a tile array. To use the utility, open agrayscale or RGB image by selecting ‘File’ | ‘Open’ as usual (currently, tiling isonly implemented for TIFF images). Select ‘Post Process’ | ‘Tiling’ and either‘Grayscale Image’ or ‘Color Image’, depending on your input file.PANCROMA TM will read in your file and present a Tile Data entry box as shownbelow. By selecting between the two radio buttons you can either specify thetiling by the number of row and column tiles or by the number of pixels in the tile.(If you specify by pixels, PANCROMA TM will generate square tiles with an equalnumber of row and column pixels in each tile.) When you have made yourselection, click ‘Enter’. PANCROMA TM will then present you with a file savedialog box. You must specify the base file name for the tiles. PANCROMA TM willappend a row and column index code to each tile. For example, the first tile inthe first row will be saved as basefilename0-0.jpg, the second tile in the first rowwill be saved as basefilename0-1.jpg, etc. At this time only JPEG is supportedas an output format.216
