View ArticleNew Post: Edit JPEG metadata?
Greetings - I was wondering (hoping, really) if this library could be used to edit metadata in an existing jpeg? For example add text to the comments or description field(s) ? Thanks!

That's out of scope for this library. This lib here is pretty cool and provides what you are looking for: http://www.codeproject.com/Articles/47486/Understanding-and-Reading-Exif-DataRene

View ArticleNew Post: [SOLVED]FillEllipse() breaks for large ellipses
I would argue that this fix should be in the official release. Does it have a negative impact on performance? Drawing large ellipses is not that uncommon nowadays.

I need to draw rotated ellipses. It seems this is not supported by the library. How can I extend DrawEllipse with this feature? (Performance is top priority.) Please advise!

What do you mean rotated? If you rotate throught the z axis, then just provide different x, y value, you can compute those with an angle feeding into sin and cos.

What you want is a rotation after, so use the WBX RotateFree method after drawing the shape to the WB.

View ArticleNew Post: drawing outside the boundaries
Yes, it will be clamped to the boundaries. Maybe you can use the DrawLine and just use two lines? Or just use the source code, change the boundary check and use your custom build of WBX. :)
