[ITK] Decode a medical image from memory buffer in ITK

[Fijoy Vadakkumpadan]

Hi Dženan,

Correct me if I'm wrong, but the Import filter assumes that I have the
medical image metadata (size, resolution, etc.), and the decompressed data
(the C-array). However, I do not have these.

All I have is a buffer *buf* containing the encoded image, i.e., *buf* is
filled like so:

unsigned char buf[MAX_FILE_SIZE];
f = fopen("myImage.dcm", "rb");
n = fread(buf, MAX_FILE_SIZE, 1, f);

In other words, I'm looking for a class that can read an image from a
buffer, just like ImageFileReader reads from a file. Does such a class
exist?

Thanks,
Fijoy
