ImagePng not working properly

[Anon]

Hi there,

I have installed php with gd-support..
but when using the function ImagePNG, it gives no output.

but php supports ImagePNG:
this function says that PNG support is enabled.

if (ImageTypes() & IMG_PNG) {
echo "PNG Support is enabled";
}

I'm using this piece of code to test:
<?php
header ("Content-type: image/png");
$im = @ImageCreate (50, 100) or die ("Cannot Initialize new GD image stream");
$background_color = ImageColorAllocate ($im, 255, 255, 255);
$text_color = ImageColorAllocate ($im, 233, 14, 91);
ImageString ($im, 1, 5, 5, "A Simple Text String", $text_color);
ImagePng ($im);
?>

It gives no errors or something, but there's just no image..

Anybody kwow how to solve this problem?

thanks,
Thomas

Does it produce no output or does it give a broken image?
Try running the script without the header, to see any error messages.

it produces no output (Page cannot been displayed).

when I do not add the header, the same occurs..

Remove the @ sign from the imagecreate function.

That doesn't change anything...

Alle gd fucntions work properly (without errors), but ImagePng doesn't return an image..
it returns nothing.. 🙁

I had the same problem.
If the temporary folder (/tmp) is out of space, ImagePng will output only the header and no picture.
It will gives no error message.
