Syntax
<Result> = <Image control>.PixelColor(<X-coordinate> , <Y-coordinate>)
<Result>: Integer
Color of the specified pixel in RGB format.
Caution: the value returned may differ according to the display configuration (resolution, ...).
<Image control>: Control name
Name of the Image control to be used.
<X-coordinate>: Integer
Horizontal position of pixel to use.
<Y-coordinate>: Integer
Vertical position of pixel to use.
Remarks

Coordinates

Coordinates are given in pixels with respect to the upper-left corner of the image (coordinates: (0.0)).
To retrieve the position of a mouse click in an Image control, use MouseXPos and MouseYPos.

How to retrieve the components of the color?

To retrieve the components of the color returned by <Image>.PixelColor:
  • To get the red component, use RGBRed (or perform a division modulo 256 of <Result>),
  • To get the green component, use RGBGreen (or perform a division modulo 256 of <Result>/256),
  • To get the blue component, use RGBBlue (or perform a division modulo 256 of <Result>/256/256).
Reports and QueriesWindows

<Image>.PixelColor, Zoom and automatic scrollbars

The "Automatic scrollbars and zoom" option, available on Image controls, is incompatible with <Image>.PixelColor. If this option is used on the Image control, <Image>.PixelColor freezes the image. The zoom and the scrollbars are also frozen.
