Hi;

Does anybody know how to draw multiline text with automatic line breaks rotated by 90°.
I would prefer a function similar to CDC::Drawtext() where I only have to specify several alignment flas and the bounding rectangle.
I searched the web with no success...

Any help is very welcome!

Hi,
 
Windows API doesn't support it :( You can only manually splt and draw each line.

Use GDI+ or simply draw to a bitmap which you rotate afterwards.

I know this, but it doesn't help here. This class only uses single line rotated text, no wordbreak no ellipsis...

Draw to bitmap, then rotate using primitive GetPixel/SetPixel :).

Thanks znakeeye but I won't do that --> performance issues. Now I write my own DrawText function, that manually splits the text and draws it using rotated font with TextOut(). It's a little bit more of work, but worth to do it this way...

If you need performance, why not use GDI+? It supports rotation of text...

Yes I know this, but not for any kind of orientation and escapement...

I remember Charles Petzold made exactly what you're trying to do, with GDI. Search the net for petzoldi.chm and you'll find it!
