nanogui: Thread: freetype2 in portrait mode doesnt work

Hello,

I enabled portrait mode in mwin/winmain.c with
GdSetPortraitMode(psd,MWPORTRAIT_RIGHT);

Normal grapic output is ok, but no ttf output is visible.

Without portrait mode everything is working.
I am using framebuffer with MWPF_TRUECOLOR565 and freetype-2.1.3 on
mipsel-linux.

Can somebody give me a hint what is going wrong?

That's pretty strange, but the TTF font engine uses GdBlit to
display font glyphs, and it sounds like that's where the problem
lies.  I would think it would just display incorrect orientation,
rather than no display.  Are you getting any screen output where
the text should be?  What color?

Check the GdBlit call in engine/font_freetype.c for more details.

Hello Greg,

I found the solution.

Paul Bartholomew made a change to fbportrait_left.c (Adding a DrawArea()
member in the SUBDRIVER structure) some time ago (I found this in your
ftp-patch directory).

With this changes output in PORTRAIT_LEFT mode is OK.

By the way: Thank you very much for your great work on microwindows -
nanox!
The WINDOWS GDI kompatible API is great for me, because I am debugging
and writing my application on a windows machine. Recompiling the same
code produces a linux binary.

Is there a time schedule for releasing a version 0.92?
I think many extensions and patches are available since 0.91.

Bye

So the portait left mode fix works, and you've changed code to
make it work portrait-right?  Is this code not in CVS?  If not,
please send a patch, thanks!

Yes, we need to release v0.92.  I suppose updating the web
site and release current CVS would be the way to go.

New fbportrait_left.c code is not in CVS yet.
I use PORTRAIT_LEFT mode at the moment and havent't created a new
fbportrait_right.c.

I'm experiencing the same issue (no visible output when using FreeType 2).
My device is not in portrait mode and is able to display the built-in
fonts. Image BLTs also work OK. I guess I need to debug into
GdDrawAreaInternal to see what's going on. Here is some debugging output
to verify that FreeType is functioning correctly:

Apologies for the double message. I sent the original five days
ago and sent a new one yesterday when the original had not
appeared yet.
