opening files for writing

[Anon]

I am taking my first tentative steps in using the gd library with the problem of taking an image and magnifying it four times and storing both in seperate files and showing the results to the browser.

However i get an error coming from the ImageGif() function which states that it is unable to open a gif file for writing.

I then wrote in a line before this
fopen(\"...\", \"w+\");

which resulted in an error message permission denied.

Here is the modified code

<?

$size = GetImageSize(\"logoBefore.gif\");
$imageIn = ImageCreateFromGif(\"logoBefore.gif\");

$imageOut = ImageCreate($size[0] 4, $size[1] 4);

ImageCopyResized($imageOut,$imageIn,0,0,0,0,$size[0] 4,$size[1] 4, $size[0], $size[1] );

fopen(\"logoAfter.gif\",\"w+\");

ImageGif($imageOut, \"logoAfter.gif\");

ImageDestroy($imageIn);
ImageDestroy($imageOut);

?>

<IMG SRC=\"logoBefore.gif\" BORDER=0>

<IMG SRC=\"logoAfter.gif\" BORDER=0>

Any thoughts would be kindly appreciated

What version of gd to you have?

Versions of gd older than gd-1.6 support gif format images, and do not support png, where versions greater than gd-1.6 support png, not gif.

If you have a version that doesn't support gif, either start using png, or download an older version of gd at www.rpmfind.net or somewhere else.
