Save GD image

[mhalloran]

Ok, I'm trying to make an image grayscale. I got that to work. Now I want to save the image in a directory and NOT display it on the screen. The code below works but it also outputs an empty image box on the screen:

header ('Content-type: image/jpeg');
$img_locate	="some_image.jpg";
// Load the target image
$rDestImg = imagecreatefromjpeg($img_locate);

// Create a blank source image
$rSourceImg = ImageCreate (0,0);

// Merge the source with the destination
ImageCopyMergeGray ($rDestImg, $rSourceImg, 0, 0, 0, 0, imageSX($rDestImg), imageSY($rDestImg), 0);

// Save new image to server 
Imagejpeg($rDestImg, "some_location/newname.jpg");

The last line is the one I'm having problems with. It saves the file but I don't want any output on the screen.

Any ideas?

have you tried this?

header ('Content-type: image/jpeg');
$img_locate	="some_image.jpg";
// Load the target image
$rDestImg = imagecreatefromjpeg($img_locate);

// Create a blank source image
$rSourceImg = ImageCreate (0,0);

// Merge the source with the destination
ImageCopyMergeGray ($rDestImg, $rSourceImg, 0, 0, 0, 0, imageSX($rDestImg), imageSY($rDestImg), 0);
ob_start();
// starts the output buffer
// Save new image to server 
Imagejpeg($rDestImg, "some_location/newname.jpg");
ob_end_clean();
// deletes the output buffer

hope it works 🙂

The buffer trick didn't work but all I had to do was remove the header:

header ('Content-type: image/jpeg');

And everything was cool. Thanks for posting 😉
