#1446 closed Bug (Fixed)
_Screencapture_Capture UDF height and width is 1 pixel off
| Reported by: | djbarnes@… | Owned by: | Jon |

Description
Screencapture_capture will return a square that is 1 pixel too small both in width and in height.
Imagine a grid of pixels 3x3. You want to capture pixel 1,1 - 3,3.
so you run the command:
_ScreenCapture_Capture ("example.png",1,1,3,3)
however, in _ScreenCapture_Capture the following code exists:
Local $iW = $iRight - $iLeft
Local $iH = $iBottom - $iTop
so $iW = 3-1 = 2
$iH = 3-1 = 2
returning an image 2x2, which isn't what you want. The rectangle is inclusive of the last pixels.
recommended fix:
Local $iW = $iRight - $iLeft + 1
Local $iH = $iBottom - $iTop + 1
Although this bug is minor, If you are doing pixelchecksum and using Screencapture_capture to test your code this can cause hours of headaches!
