Please anybody guide me, I am using following code for display image on screen
header('Content-Type: image/jpeg');
$magick_wand = NewMagickWand();
if (MagickReadImage($magick_wand, "paste_img/20070309130202.jpg") != 0)
{
MagickSetFormat($magick_wand, 'jpeg');
MagickEchoImageBlob($magick_wand);
}
else
{
echo MagickGetExceptionString($magick_wand);
}
DestroymagickWand($magick_wand);
But it will display junk character on screen.

Re: MagickEchoImageBlob() display junk character on screen
I am also having this problem. I have recently installed ImageMagick and Magickwand on ubuntu for use with PHP.
I am able to load an image, rotate it, takes its width and height, however whenever i try and use
MagickEchoImageBlob i get a bunch of random characters and junk where the image should be. Tried with a .jpg and a .png image.

Code: Select all
<?php
echo <<<html
Test image rotate: <br><br>
html;
$resource = NewMagickWand();
MagickReadImage( $resource, 'images/image_1.jpg' );
$w = MagickGetImageWidth($resource);
$h = MagickGetImageHeight($resource);
echo "image height & width: $h , $w <br>";
//=========================================>
// Rotate the image and see if the width
// and height change properly
//=========================================>
echo "Rotating image.... <Br>";
MagickRotateImage($resource, null, 90);
$w = MagickGetImageWidth($resource);
$h = MagickGetImageHeight($resource);
echo "rotated image height & width: $h , $w <br>";
echo "Image: <Br>";
MagickEchoImageBlob($resource);
?>

Re: MagickEchoImageBlob() display junk character on screen
You know what, in my case it doesnt matter anymore. I have found an easy way around it.
I'm just saving the image now and displaying it the way i normally would with HTML.
Heres the code of loading an image, rotating it, saving it, and then displaying it.
Each time the page refreshes, the image rotates.
