i need scan large area. i can use if pixelgetcolor(x,y) = oxfffff then XXXXX but its scan only 1 pixel.

how i can make it scan like 50x50 pixel areas?

[Jex]

Use PixelSearch ?

PixelSearch(1,1,50,50, Color)

[fataly]

PixelSearch(1,1,50,50, Color) these 50,50 means areas?

and 1,1 y and x axels?

[Jex]

Searches a rectangle of pixels for the pixel color provided.

PixelSearch ( left, top, right, bottom, color [, shade-variation] [, step]] )

left: left coordinate of rectangle.

top: top coordinate of rectangle.

right: right coordinate of rectangle.

bottom: bottom coordinate of rectangle.

colour: Colour value of pixel to find (in decimal or hex).

shade-variation [optional]: A number between 0 and 255 to indicate the allowed number of shades of variation of the red, green, and blue components of the colour. Default is 0 (exact match).

step [optional]: Instead of searching each pixel use a value larger than 1 to skip pixels (for speed). E.g. A value of 2 will only check every other pixel. Default is 1.
