Transform module to rotate a display 90 degrees counter-clockwise
io-graphics -Tdevg-rotate90.so [option[,option ...]] ... &
x86, PPC, MIPS, ARM, SH4
None.
The devg-rotate90.so transform module is used by io-graphics to switch the display between portrait and landscape views.
devg-rotate90.so is loaded by io-graphics using the -T option. For more information on options, see io-graphics.
You need to modify the X and Y resolution passed to io-graphics using the -g option when you use the transform module. For example, to rotate a 640x480 16-bit color display 90 degrees counter-clockwise:
io-graphics -Tdevg-rotate90.so -g480x640x16
Transform modules can be cascaded to flip the display, i.e. rotate 180 degrees:
io-graphics -Tdevg-rotate90.so:devg-rotate90.so
io-graphics, devg-rotate270.so
