displaying jpg images using image functions

Anon

Hi guys,
can anyone look at my problem, details gien below

Problem in using Image Functions ImageJpeg,CreateImagefromJpeg...

Here is a small program:
<?
$im = createimagefromjpeg("mandrake.jpg");
imagejpeg($im);
imagedestroy($im);

When I open this in a browser, I get a warning message as follows:

Warning:your php build has no support for functions CreateImageFromJpeg,ImageJpeg

Apache_1.3.11,Php-4.0.0, gd-1.8.1, jpeg-6b are installed on my system and php is built with gd-1.8.1 library support.

But the same php works for Gif Images.

Please suggest possible solution.

Hi Kiran,

I'm working on somewhat the same platform as U R. I have a few doubts if U could kind enough and care to clarify :

Firstly, As far as I know, only pre-1.6 release versions of the GD library supported GIF images. I've tried later versions of the GD library and all GIF support has been removed. Are you positively sure that U can create & manipulate GIF images with GD 1.8.1 ? Have U actually tried it and does it work ?

Secondly, i'm also under the impression that the GD 1.8.1 supports only PNG formats. How does creating JPEGs come into the picture ?

Thirdly, Does PHP have any built in functions for working with JPEGs ? I've come across only GIF functions so far. Is there really anything like "CreateImageFromJpeg()" function or "ImageJpeg()" function ?

Lastly, U mentioned something like "jpeg-6b " in U'r mail. I haven't really come across this before. I'd appreciate it if U could care to enlighten me on its functionality.

Thanx a million.

Ok this is a link to a link message, but hey.
I just installed php-40 on my server, have the latest gd/zlib and all that jazz. gd on the phpinfo() looks clean (suffice to say it's enabled) Now my next step is to find any sort of examples on how to use the png/jpeg create images. I want to play with graphics! But goodness, there is such a lack of documentation on the subject that it's hard start. So if anyone has a heads up (particularly on how to overlay text onto a JPG) I'd love to see an example!
