[Mono-winforms-list] Font patch for libgdiplus
Hi folks,
This patch removes libgdiplus dependency against Cairo
_cairo_toy_font_face_create API function. This API call is an internal
Cairo API call (not part of the public API). Also, on Cairo 1.2 is no
longer exported.
I have tested the patch with a few SWF apps and the SD font creation
samples and it seems to work fine.
I'll appreciate if you try it before I commit it.
Regards,
Jordi,

[Mono-winforms-list] Help contributing to libgdiplus and Cairo integration
Hi all! As you probably know Cairo 1.0 includes antialiasing support. This is something important for libgdiplus because all the drawing operations in System.Windows.Forms are based on the old Windows GDI and they use no antialiasing. After turning antialiasing off in Cairo 1.0 we noticed that DrawLine and other functions basic drawing functions started to work different that expected. With antialiasing off in Cairo lines that are supposed to be a single pixel width have various variations in width. This a well-know and documented issue. John Hobby did his PhD on the solution to this problem. There is a shorten version of PhD findings on the web: [Hobby89] John D. Hobby, Rasterizing Curves of Constant Width, JACM 36(2), 1989. http://cm.bell-labs.com/who/hobby/87_2-04.pdf In order to fix this problem the best solution is to implement an algorithm to generate Hobby's "Pen polygons". These respect the desired width and will make us to look right when AA is off. According to Cairo hacker's, a hack in cairo-pen.c:_cairo_pen_init with Hobby's algorithm will fix the problem. We are looking for someone that wants to contribute to the Mono project in graphics area and help us implementing Hobby's Pen polygons in Cairo.

Kornél, keep in mind that this is a "managed" Windows implementation of System.Windows.Forms. We are trying to share as maximum as possible between platforms.

Hello Pedro, I wrote the Datagrid control that is the grid control in .Net 1.1. I decided to go handle the scroll myself and do not use the ScrollableControl class because I think that it brings little benefit to the needs. My suggestions are: a) Write samples to understand exactly all the features that the grid has. Grids are fairly complex controls and if you miss a property or a feature that may break your design in a few weeks when you just realise this new feature. b) In the DataGrid control in .Net 1.1 the cells are painted using the paint methods of DataGridColumnStyle derivated classes. You should only create the editors only when need it. c) Look in SVN at the files DataGrid.cs DataGridDrawingLogic.cs located at mcs/class/Managed.Windows.Forms/System.Windows.Forms to see how the old DataGrid was implemented. It works pretty well on Win32 but on X11 we still need to do some fixes.

Laurent,
If you call Dispose the resource should be freed, as users will expect.
Also, Microsoft does works this way.
Attached you have a patch that fixes our Dispose method. Please, if this
still do not work for you, send me the sample and I'll look into it.
Thanks for your feedback Laurent,
Jordi,

There are some test cases Test/System.Drawing.Imaging in. But, there are no cases for the new code. If Jonathan can provide then it will be cool, if not, I'll write them.

I did fix some issues time ago to make libgdiplus standard ANSI complaint. Can you please send me or to this list the changes that you have made into libgdiplus in order to make it compile on Solaris 10? We are very interested in looking into them and fixing it in SVN. Thanks!

Good work Johnathan!
One small thing. At bitmap.c, line number 425, the following function
call:
+ if (!gdip_is_an_indexed_pixelformat) {
does not have the parameter need for the call, that looks like it has to
be (srcData->PixelFormat)
It looks fine to me also. A part of that I ran some regression testings
and it passes them.
I can commit it if no one objects.
Jordi,
