Hi everybody,
I am still strugling with the crop problem.
It looks like it is not possible with PHP to do an imagecopyresampled
and and imagecopy on the same image.
Here is what I try to do:
1: Resize image to 80px width and correct ratio
2: Crop from that image a 80x60 part
Both work for themselfes, but not together.
Does anybody see the problem?
$outputImg = ImageCreateTrueColor($maxX, $dstY);
imagecopyresampled($outputImg, $inputImg, $posX, $posY,0,0, $picX,
$picY, $srcX, $srcY);
$outputImg = ImageCreateTrueColor(80, 60);
imagecopy($outputImg, $inputImg, 0,0 , 0, 250, $picX, $picY);
If I leave the second imagecreate away, the image will be copied into
the bigger size and is not 80x60.
Thank you for any help.

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
