heh Ron, you've been around this list long enough to know that you
should STFW and RTFM before posting questions.

Hi there,
I need to manipulate images on the fly. My goal is to make the image
very bright, or to add a sepia effect. The problem is, that this takes a
lot of computing power on 1024 pictures. About 2s on my server until the
image is delivered.
Does anybody know a high performing image
Hi Merlin, that is very fast for 1024 images, you will not get much
more speed if you try doing anything smarter ,
though there are some image libraries that are faster than GD libs eg

You can use ImageMagik (aka 'convert') through http://php.net/exec if
ImageMagik is installed, and the PHP user can run it.
I'm guessing that the same could be said for the GIMP

or height have it scale it down proportionally to that width or

Ok, I've been looking at the image functions, and found that I needed
to recompile PHP with exif support and load GD and other functions.
I've done all of that and now I get the following:
Source: /home/jamboimages/images/uploads/alamoarea_97_round_sm.jpg
600 : /images/patches/1997/1997R15.jpg
exif_imagetype() is new function only available in PHP 4.2 (not released
yet) and above. Use GetImageSize() for now.

Hello all. I have a PHP script which retrieves records from a database,

with this image:
See what it's size (pixes) is

Move it to a different location

I guess I should clarify. If the image that's referenced in the

pixels wide, keeping the height proportional. Then, save that
image to a new name somewhere else in the filesytem. Then I want
to reduce the image further to 300

On the topic of gd support but a slightly different topic-
I was using php 4.0.5
gd 1.8.3 patched for gif support (using libungif for libgif which I
*think* is OK)
FreeType 1.3.1 (compiled myself in /usr/local )
t1lib 1.3.1 (compiled myself in /usr/local )
I was using gd to draw pictures and
reading the ./configure -h I see that they CHANGED what the configure
options mean.
now --with-freetype=dir refers to freetype 2
Untrue, it only refers to freetype2 when you are building against GD2.
phpinfo() says I have FreeType linkage.
But both ImageFtText and ImageTTFText fail to do

Adam -
If you're on a machine that has ImageMagick installed on it
(most Linux boxes I've been on have it installed already)
you can do something like this in PHP:
$origfile = /home/bob/my_face.jpg;
$img_dir = /usr/local/www/htdocs/images;
$dest_file = $img_dir . /t_ . basename($userfile) .
Does any one know if you can check the dimensions of a GIF file?
