Stop using System.Drawing
opcon opened this issue · comments
The System.Drawing namespace always causes problems with Mono, and while QuickFont works okay now, it is a good idea to move away from System.Drawing altogether.
The following is a list of ways System.Drawing is used in the current codebase, and a replacement:
| Use | Alternative |
|---|---|
| Bitmap manipulation | ImageSharp, a cross-platform image manipulation library. Still in early alpha, but probably usable enough. |
| Size/Rectangle/Point structs | Can just implement these as standalone structs - see OpenTK |
| Text Rendering hints for bitmaps | Not sure if this is needed or will make a difference |
| Converting SharpFont FTBitmaps to GDIBitmaps | Can replace this conversion mechanism with one using ImageSharp |
| Loading fonts in the GDIFont class | No alternative, this method of loading uses System.Drawing specifically for loading the fonts and so will be removed along with System.Drawing |
| Color class/list | OpenTK has Color4, could use that instead. What does ImageSharp use? |
| Font Style | Can create a simple enumeration for this |
| Brushes | Can probably use ImageSharp |
ImageSharp contains the Size, Rectangle(F), Point structures, as well as an equivalent of the System.Drawing.Color struct. There is also some form of brush support.
