Opens a spreadsheet window for the current image. Pixels can be displayed as decimal integers, hexadecimal integers, RGB values, or hexadecimal RGB values. If a FFT is being displayed, the real or imaginary components can also be displayed as floating point numbers. Changes of pixels on the image (for example, by adding a label or changing the contrast), are immediately reflected in the spreadsheet. Similarly, typing a number in the spreadsheet changes the value of the corresponding pixel (if the number is a valid pixel value). Also, selecting an area on the image automatically causes the corresponding part of the spreadsheet to be highlighted. This gives precise control over the image as a numerical array. A separate spreadsheet can be activated for each image.
Since imal can read and write 1 bit/pixel images as raw bytes, the spreadsheet can also be used as a bitmap editor.
