Write pixels on a brushBrush

[ilbarbax]

Hi,

I'm in troulble modifyng brushes. The intention is to have a brush, draw some graphic element on it and then have all saved in the brush.
My code is as follow:

SetClipRegion(1)
DisplayBrush(998,abx,aby)
SelectBrush(998)
Line(xact,yact,MouseX(),MouseY(),Forecolor,{ Thickness = Lineth})
EndSelect
; DisplayBrush(998,abx,aby)
SetClipRegion(0)


and does not work

From that short example it's impossible to find out what's wrong. I recommend that you start with a simple example like this:

Code: Select all

CreateBrush(998, 200,200)
SelectBrush(998)
Line(50, 50, 100, 150, #RED,{ Thickness = 10})
EndSelect
DisplayBrush(998,0,0)

WaitLeftMouse()

And then add step by step other features like clipping and mouse handling etc.

Solved... code was corrected, however there is a diferent behaviour on mouse chordinates when retrieved absolute via MouseY() and Y and when used into a brush via Select. in this case the choordinate system is relative. Therefore from the mouseX and Y you need to detract the reference point X and Y of the brush.... Not one of my best explanations!
