return output from call to ImageMagick??

the_reverend

Ok, currently I have this:

$thumbnail = exec("convert -geometry $dest_width x $dest_height $image jpg:-");

It doesn't work. What I'm trying to do is have image magick convert $image into a thumbnail of size dest_width x dest height and return the thumbnail to $thumbnail. What am I doing wrong? How do I make this work???

Thanks.

Still not working...

snip

$thumbnail = passthru("convert -geometry $dest_width x $dest_height $image jpg:-");

snip

$thumbnail_data = addslashes(fread(fopen($thumbnail, "r"), filesize($thumbnail)));

snip

$query = mysql_query("INSERT INTO images VALUES ('','$gallery','$temp',NOW(),'$uid','','$uid','$caption','$image_type','$image_data','$thumbnail_data');");

Hi,

convert will take two arguments

- the input file
- the output file

and of course, what to you want as
size, file format and so on

So use an output filename and then
open it the way you prefer ( file()
or fopen(), or ...)

I'm not sure the '-' trick for
standard output will work here
    but maybe you don't need the ':'
in " jpg:- " string at the end ?
just " jpg - " ?

I have issues with file read/write permissions on my server, so I have decided to store my images in a mysql database. I know there are issues with this, but there are bigger issues with the fact that I have to manually create directories and chmod them as 777 to write files from a script to my server...

So I need to be able to send a binary string $image to image magick and get a binart string returned to $thumbnail without any file read/write.

Any ideas?

I still can't get it to work and I haven't found anything to tell me what to do. I need to pass a variable's contents to imagemagick and have it return the result image to a variable in my php page without reading or writing to a file at any point.
