Out of Memory Exception: System.Drawing.Image.FromFile

[anastasia]

I get an out of memory exception when attempting to excecute the
following code:

original = System.Drawing.Image.FromFile(file.FileName,true);

I ONLY get this exception when the file is in the "My Documents"
folder or subfolders. If the file lives anywhere else on the hard
drive, I have no problems.

What could be going on here?

Thanks in advance,
Stacey

I had this problem when first learning how to create thumbnails from images.
Unfortunately, I don't remember the specific problem....however, I think
you'd do much better off by creating an Image object from a byte array.
Grab the file from a FileStream object first and then create the image
object from a BinaryReader off the FileStream instance....

If this isn't helping you...post back and I will give you code I use to
manipulate images from files/streams....just don't have it now...it at work
;-).

I am getting similar kind of error

Hi
I am getting the similar error.
I have a 6 MB JPG file. This file I receive in the form of byteArray from client. I create a stream object out of this byte array and load the image from this stream. Here is the code

Dim strm As New MemoryStream(data, False) 'data is the bytearray received from the client

dim img as image

img=img.fromstream(strm) ' This is the point where I get out of memory.

I have disposed off the image and everything the moment I create thumbnail. How do I resolve this?

From reading the above posts I was able to quickly figure out what my issue was. Maybe this is the same for you guys.

The Out of memory exceptions is being thrown because of the security setting on the file. I copied it into the IIS folders without resetting the permissions. Once I gave ASP.NET permissions on the file (or allowed it to inherit permissions from the parent folder) .... it loaded with no problem.

Hope this helps someone. And it only took me a year to respond.
