hi,
this is an open source which i picked up from somwhere on this site, the only adjustment i need to make is to increase the size (height n width) of the output file. at the moment the output image is seqeezed so i would like to make it slighlty larger.
this is the coding:
<?php
$data = explode(",", $_POST[‘img’]);
$width = $_POST[‘width’];
$height = $_POST[‘height’];
$image=imagecreatetruecolor( $width ,$height );
$background = imagecolorallocate( $image ,0 , 0 , 0 );
//Copy pixels
$i = 0;
for($x=0; $x<=$width; $x++)
{
for($y=0; $y<=$height; $y++)
{
$int = hexdec($data[$i++]);
$color = ImageColorAllocate ($image, 0xFF & ($int >> 0x10), 0xFF & ($int >> 0x8), 0xFF & $int);
imagesetpixel ( $image , $x , $y , $color );
}
}
//Output image and clean
header( “Content-type: image/jpeg” );
ImageJPEG( $image );
imagedestroy( $image );
?>
where would i have to make the neccessary changes?
cheers
