Problems

• Image too large.
  • Resize with Edit -> Scale and Rotate...
    • This resamples the pixels - the actual image data is changed.
  • I don't know any way to zoom down a large image, so that the image fits on the screen but the original pixel data is retained. ImageJ, MacLisipix and Adope Photoshop will zoom down.
• The color scale and the LUT window are garbaged.
  • Revert to gray scale if appropriate using Options -> Grayscale.
  • Covering then uncovering a pseudo RGB window might damage the color scale - PC only. I do not know how to restore the color scale. The RGB image must be reconstructed from the original (Stacks -> RGB to 8bit color).
  • Use the Options -> Grayscale menu *before* loading the image.
• Insufficient memory
  • (Mac Only) Increase the memory allocation. In the finder, select NIH Image application (without it running), then use the File -> Get Info menu. Add more memory in the Preferred Size box.
  • If the Undo or clipboard buffer size is too small, increase it in the dialog box presented by the Options -> Preferences menu. Then invoke the File -> Record Preferences menu. On the Mac, doing this might also requiring increasing the memory allocation. Quit and restart Image.
• Threshold band in LUT window is only 1 pixel wide and stays that way.
  • File -> Revert to Saved.
    • Work on the image up to this point that has not been saved will be lost.
• Computer seems busy with Scion Image open, but not doing anything:  Use the Task Manager to monitor CPU activity, and note that it is busy except when the menus are selected.  This should not be a problem unless you are doing other things with your computer and Scion Image is open.
