Set Pixel Value


The Set Pixel Value command changes the pixel value at a specific (column, row) coordinate of the Image Cursor. While this dialog is open, you can position the cursor on the image using the standard methods. In addition, the detailed image coordinate information from the image may be viewed or hidden using the Show / Hide button. The related Set Region Value command sets a rectangular region to a value. The Edit Pixel Values command allows you to view or edit a region of pixel values.
