devg-rotate270.so

Transform module to rotate a display 270 degrees counter-clockwise

Syntax:

io-graphics -Tdevg-rotate270.so [option[,option ...]] ... $

Runs on:

x86, PPC, MIPS, ARM, SH4

Options:

None.

Description:

The devg-rotate270.so transform module is used by io-graphics to switch the display between portrait and landscape views.

devg-rotate270.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 270 degrees counter-clockwise:

io-graphics -Tdevg-rotate270.so -g480x640x16

A 270 degree counter-clockwise turn is equivalent to a 90 degree clockwise turn.

Transform modules can be cascaded to flip the display, i.e. rotate 180 degrees:

io-graphics -Tdevg-rotate270.so:devg-rotate270.so
