The expImage function exports a matrix object as an image file. The matrix object of any data type can be used as input, but it might be converted to another data type according to the settings and output type.

Eight export file types (BMP, GIF, JPEG, TIFF etc) are supported. Users can choose among them according to their needs.

You can also specify DPI resolution, color depth, etc. using the Image Settings tree in the dialog. Please select a file type before you use this tree, because different settings are available for different file types.
