Copying half a pixel? I dare say that's where the problem is.

Hi there,

I do have a small problem with the proportions of image copy

The image is originally vertical in 100px width and 141px height.
Now I want to crop it to 80 px width and 60px height. There should be no black area and the proportions should be OK. That means that I have to copy only part of the image. In this case it would be 40.5px from above (141-60 / 2 ) and until 100.5 (40.5+60).
This would crop the middle part of the image.

Now with imagecoyresampled I can set the starting point of 40.5px, but not the ending point. The image will have a black bottom.

Here is the code I am using:
imagecopyresampled($outputImg, $inputImg, 0,0, 0 , 40.5, 80, 60, $srcX, $srcY);

Thank you for any hint. Maybe somebody has a good idea on how to crop that image.

Best regards,

Merlin

got it, wrong command.
This is the right one:
imagecopy($outputImg, $inputImg, 0, 0, 0, $cropY, $srcX, $srcY);
