[RESOLVED] Need help with imagecreatejpeg()

frih

i tried to create a temporary jpeg file using imagecreatefromjpeg() function but it is showing me this error--

The source image file has size around 3.5mb.

Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 12288 bytes) in C:\xampp\htdocs\image\temp1.php on line 10

need help....

the process needs more RAM than your php-config allows. you can change the memory limit in your php.ini. config ist: memory_limit ... set it f.a. to 100M

The file size is irrelevant; what's important is the amount of memory required to store all the uncompressed pixel data: width in pixels × height in pixels × 3 bytes per pixel.

While I can't verify the formula used, one user-submitted comment has proposed this custom function as a solution to this problem; when used before the imagecreate*() functions, it will examine the (image?) file and increase the current memory limit, if necessary, based on the amount of memory that file will probably consume.

i have increased the memory size but still no help, it is showing that message only...

the resolution of the image which i was using is too large..

As Weedpacket points out, you can estimate the memory that a given picture will need by looking at its dimensions/resolution. If your system doesn't have enough RAM, then yes, the resolution is too large for the GD library to work with it.

If your goal(or, in this case, a requirement) is to resize the picture, you might consider looking at using 3rd-party software such as ImageMagick.

Uh..., GB, not MB; get some sleep 🙂

So what did you increase it to?

I HAVE 2GB RAM....

"memory_limit = 2G" (which is how it would be written in php.ini)?

Oh good grief, how in the... sigh nevermind. Apparently I didn't like the metric prefix "kilo" and had decided to ignore it. Oops. :o
