Problem using imagecopy

[stevesimo]

Hi, I am having difficuly using the imagecopy command.  I have a large image and I am trying to copy a small area of this image and save this to a file.  However I cant get it to work and am not sure where I am going wrong.  Here is my code

 

  
  $imagefile = 'largeimage.png';
  $src = imagecreatefrompng($imagefile);
  $dest = imagecreatetruecolor(83, 24);

  // Copy small image from large image
  imagecopy($dest, $imagefile, 358, 70, 0, 0, 83, 24);
    
  $image = 'smallimage.png';
  $newimage = @imagecreatefrompng($dest);
  imagepng($newimage, $image, 75);
  imagedestroy($newimage);

 

The main part of what I am trying to do is not just to copy the image but actually saving it to a file.  Can anyone point me in the right direction.  Thanks, Steve (Blackpool, UK)

hi, thanks for your code, i have uploaded it and it seems to run ok, however when I try and access the small image which has been created, my browser simply displays the path of the image, not the image itself.  Do you have any ideas as to what this might be?

 

Thanks

I removed the 75 of the imagepng command and now the image displays but simply as a black rectangle.

 

Could this be because my image coords are incorrect?

Sorry, missed that one

 

imagecopy($dest, $src, 0, 0, 358, 70, 83, 24);
