Example
// Identify the color of the pixel (15, 25)
// in the Image control named "IMG_Drawing"
ResColor = IMG_Drawing.PixelColor(15, 25)
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 Image control to use.
<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 top 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).

<Image>.PixelColor, Zoom and automatic scrollbars

The option "Zoom and automatic scrollbars" available for an Image control is not compatible with <Image>.PixelColor. If this option is used on the Image control, the display performed by <Image>.PixelColor is fixed in the control. The zoom and the scrollbars are also fixed.
