Good day,
I'm having a problem working with an image that I've made with
imagecreatefromjpeg. Here's the code:
$in_file = "IMG_0050.jpg";
echo "Testing for image ".$in_file."<BR />\n";
$image = imagecreatefromjpeg($in_file) || die("Failed to create image from
file.
<BR>\n");
echo "Resource ID: ".$image."<BR>\n";
echo "Image width: ".imagesx($image)."<BR>\n";
It reads in the file OK and prints out "1" as the Resource ID, as expected.
However, imagesx fails with:
imagesx(): supplied argument is not a valid Image resource in
<the_program_location> on line 9
The resource ID was returned from imagecreatefromjpeg, so, I have no idea
why it's "not valid". The image in question displays fine in Mozilla, etc,
if that matters at all- and it's also a fairly large image, if that matters
at all too. Other PHP functions that work with the image resource fail in
the same way.
This is on 4.3.3 / FreeBSD 5.1, built from the ports collection . I have
also tried this on Red Hat 9, with a similar failure.
Here's my phpinfo()'s configure:
'./configure' '--enable-versioning' '--enable-memory-limit'
'--with-layout=GNU' '--with-zlib-dir=/usr' '--disable-all'
'--with-regex=php' '--disable-cli' '--with-apxs2=/usr/local/sbin/apxs'

'--with-xslt-sablot=/usr/local' '--with-zip=/usr/local' '--with-zlib=yes'
'--prefix=/usr/local' 'i386-portbld-freebsd5.1'
I have a feeling that I am missing something simple, but I don't know what
it could be. I didn't find anything in the mailing list archives, and
Googling for the error message just shows pages and pages of actual broken
web pages.
Thanks in advance for any help,
