Hi All

Thanks in advance. I am struggling with flood fill. If I draw a
(closed) shape on a tImage.Canvas and then choose flood fill, the
closed shape is filled which is all good.

However, If I load an image and copy it to the canvas in question, and
then chose flood fill the entire image is filled (i.e fill does not
stop at a boundary)?

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i
tTileIn.Canvas.Brush.Color:=tColourIn;   
 tTileIn.Canvas.FloodFill(MouseXIn, MouseYIn, tColourIn,
tFillStyle.fsBorder);     tTileIn.Refresh;                           
                               
I have tried both fill styles to no avail!

Any help much appreciated.

[Win 7].

FloodFill fills the area around (X,Y) with the current Brush.Color.

It stops filling when it meets a border (fsBorder) of a different
Color (specified as a parameter in the call), or a solid region
(fsSurface) of a different Color, or when  it reaches the bounds of
the canvas.
