As MS Cleartype has no matching functionality at all, adding this feature could
really boost spreading GDIPP by all the professional users of portrait/pivot
displays!!!
Which program triggers the problem?
Portrait LCD display orientation.
What steps will reproduce the problem?
1. Rotate LCD display to portrait orientation, and
2. switch windows (XP, Vista, and 7) to vertical screen layout
3. e.g. Right-click/Resolution/Orientation/Portrait
What is the expected output? What do you see instead?
expected:
a. font smoothing switched automatically from RGB/BGR to V-RGB/V-BGR pixel
geometry (preferrable), for any portrait display, or
b. if the above isn't possible either for single or for multiple displays, then
on detection of multiple displays with different orientation GDIPP should
switch off subpixel rendering, falling back to grayscale smoothing only
c. as an absolute and easy minimum, I can set v-RGB/v-BGR layout manually in
gdipp_setting.xml (pixel_geometry settings matching FreeType V-RGB/V-BGR
settings), or
instead:
On changing orientation (via Windows or videodriver hotkeys), all text becomes
blurred with color tint due to incorrect subpixel layout match.
It's easily tested on any display with Windows orientation option in display
options. Having pivot display isn't necessary.
What version of gdipp (including renderer)? On which operating system?
Any. tested on 0.91
