Command 0x05 "Rotate Left", 0x06 "Rotate Right", shift within a range
The "Rotate" command moves the pixels within the selected range (from the start position "Index" over the selected number of pixels "Length") (see the following example: range = pixels 3 to 8).
Via "Parameters" the number of shifted positions (see the following example: shifted by 2 pixels).
Pixels that are moved beyond the range limit are added again at the other end of the range (see the following example: Before: pixels 7 and 8 -> After: pixels 3 and 4).
Command 0x05:
