Recommended Posts

Hi

I have some issue with Pixelsearch function.

PixelSearch ( left, top, right, bottom, color )
The search direction varies as follows:
    Left-to-Right - left < right
    Right-to-Left - right < left
    Top-to-Bottom - top < bottom
    Bottom-to-Top - bottom < top

 

 

If I do  Right-to-Left - right < left

$x=PixelSearch (800 , 0, 0, 700, 0xffffff )

it return wrong coordination

insted for example the pixel is at 500x600 I get return 501x600

1 pixel to the right

 

and other one Bottom-to-Top - bottom < top

$x=PixelSearch (0, 700,800, 0, 0xffffff )

it return wrong coordination as well

insted for example the pixel is at 500x600 I get return 500x552

8 pixels to the top

Subtract 1 pixel from x result.

and other one Bottom-to-Top - bottom < top

$x=PixelSearch (0, 700,800, 0, 0xffffff )

8 pixels to the top

Add 8 pixels to y result.
