Okay I don't really know where to ask this, but I'm working in PHP at the moment, because its quick and easy so I'll start here.
I've been given the task of converting some old files. I know the files are all images, and we believe most if not all are grayscale.
The images are in a file format "ITW" which we believe dates from around 2005, and were included in RTF documents.
I have searched high and low looking for any information at all on this file format and come up completely blank. So I've started trying to reverse engineer the file format.
There appears to be atleast 2 internal formats. For one of the formats I have discovered most of the header is as follows
ident="ITW_"
unkown=256
width=316
height=238
unkown=8 (possibly bits bet colour i.e grayscale)
unknown=768
unkown=0
datasize=10552
This is then followed by what would presume is the actual image data. Can anybody help with the following section of data, see if they can spot anything that makes sense.
