So I decided to use BaH.Cairo in a recent project of mine, and I seem to have hit a snag almost straight away. Here are some images of the problem I'm getting:
Basically, I have two ovals, and I am using Cairo to render them to two separate TImages, which I then draw. In each image, the second oval I render seems to have a background of white, slanted ovals. Here is all of my Cairo code:
Method Create:cbRenderObject(obj:cbObject)
'Set up Cairo.
Local width:Int = obj.GetWidth()
Local height:Int = obj.GetHeight()
Local img:TImage = CreateImage(width, height)
Local cairo:TCairo = TCairo.Create(TCairoImageSurface.CreateFromImage(img))
Local matrix:TCairoMatrix = TCairoMatrix.CreateScale(width, height)
Local brush:cbBrush = obj.GetBrush()
cairo.SetMatrix(matrix)
LockImage(img)
Select obj.GetType()
Case cbObject.ID_OVAL
cairo.Arc(0.5, 0.5, 0.5, 0.0, 360.0)
'Shortcut for cairo.SetSourceRGBA()
SetCairoCol(cairo, brush.GetFillCol())
cairo.Fill()
End Select
UnlockImage(img)
cairo.Destroy()
'Set fields.
_image = img
_object = obj
Return Self
EndMethod
This is executed for the creation of each cbRenderObject (so, twice), and then it simply draws the images using DrawImage. I'm new to Cairo, so I have no idea what the problem could be, although it's probably something quite trivial. So, can anyone (anyone probably being Brucey :D) help me out? If you want, I'll try and recreate the problem in an example. Thanks in advance.
