What is the purpose of the Flatten and Unflatten Pixmap VIs?

Images can be represented in two ways in LabVIEW.  The first representation is that of a "flat pixmap", which is a 1D array. The Get Panel Image method returns a flat pixmap, for example.  Certain VIs, such as the Write BMP File, Write PNG File, and Write JPEG File VIs, require a flat pixmap.

If you want to display a flat pixmap in an Intensity Graph, you must unflatten the pixmap.  An unflattened pixmap is a 2D array that can be wired to an Intensity Graph. You may also wire an unflattened pixmap to one of the following VIs: Draw 1-bit Pixmap, Draw 4-bit Pixmap, Draw 8-bit Pixmap, and Draw True Color Pixmap. These VIs provide a picture as an output, which can be displayed in a Picture Indicator.

If you want to display a flattened pixmap in a Picture Indicator, then use the Draw Flattened Pixmap VI.
