TBGRACanvas2D question from tutorial page 14

[Adri]

Hello all,

When using the example from tutorial 14 (https://wiki.freepascal.org/BGRABitmap_tutorial_14) I stumble upon an error. When compiling the IDE mentiones an error [Identifier not found "TGBRACanvas2D"] regarding line 3 of the first, simple example where 'ctx: TBGRACanvas2D;' has been declared as a variable. (BGRABitmap and BGRABitmapTypes are both mentioned under the 'uses' declarations).
When I remove this variable and replace every instance of 'ctx' with 'bmp.Canvas2' this first example does compile and run, but then I get into problems with the second, 'complex shapes' example and the third regarding 'translations' off course too.
Is anybody able to shed some light on this behavior? Is it a setting in my IDE which understands that 'ctx' translates into 'bmp.Canvas2D'?        I cannot imagine / do not expect these examples are wrong in any way.
Many thanks for a reaction.
