OutOfMemoryException called DrawPath

[deltalimagolf]

I've got a PictureBox where the end user can draw rectangles, lines,

ellipses and freehand on an image. Everything works fine, except for an

occasional OutOfMemoryException. It only occurs when drawing freehand and

there's already a figure (StartFigure is called again), the first line is

added to the figure and DrawPath is called. The exception occurs (only

occasionally) when the call is made to DrawPath. It only happens when the

pen width >= 2. I can get around the exception by leaving the mouse over

the image with the left button pressed down, and pressing the space bar to

clear the exception.

If you run task manager (or better still Process Explorer) does the memory usage increase steadily or is it a single increase that causes this problem?

Also are you correctly disposing all the GDI+ objects you are creating in your drawing code? If in doubt please post the relevant code and somebody may be able to spot a problem (GDI+ isn't my strong point :))

Task manager doesn't show anything. If I use the space bar to clear the error I can continue drawing as if it never existed.

Wrote my own drawpath, works great
