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! ------------- Martin Product: Xtreme Toolkit v 19.0.0, new Projects v 19.1.0 Platform: Windows 10 v 1909 (64bit) Language: VC++ 2017 |

Hi,
Windows API doesn't support it :( You can only manually splt and draw each line. ------------- Oleg, Support Team CODEJOCK SOFTWARE SOLUTIONS |

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! |
