F. Program Limitations

There is no arbitrary limit (other than memory requirements) on the maximum number of lines in an image. The width of images, however, should be limited to 4096 pixels, since that is the size of Image 's internal line buffers. Image uses two 300K buffers as Undo and Clipboard buffers. Many functions will not work with images larger than these buffers. The size of these buffers can be changed in the Preferences dialog box. You must Quit, and then restart Image before the buffer size change will take effect.

The maximum number of characters that can be displayed, printed, or copied to the clipboard is 32,700. There is no limit to the number of measurements that can be exported to a text file.

The default maximum number of measurements is 200. This can be changed in the Options dialog box. You must Quit, and then restart Image before the change will take effect.

The maximum size of a macro file is 30,000 bytes. A macro file can contain up to 100 macros. The push-down stack used by the macro language can contain up to 150 variables.

The maximum number of images that can be opened is 1000. The maximum number of slices in a stack is 5000.

A maximum of 5000 characters can copied from the Results window or a text window and pasted into an image window.
