And what are you looking for when you say raw?
I am talking about that: http://en.wikipedia.org/wiki/Raw_image_format
Every scanner gets a scanned image primarily in a RAW-format. Then, a scanner makes the RAW->3-color-per-pixel (BMP, TIFF, JPG, …) transform. This is similar to the digital cameras operation.
The problem is that it is quite easy to get the raw image data from a digital camera – but how to get the raw image data from a scanner via TWAIN?
The RAW image is desirable to have – because it’s called “digital negative”.
As yet one can use the VueScan program to get the raw image data from a scanner – but VueScan does not use TWAIN, it does not support my scanner and at last it costs money.
