Coreldraw Wavelet image format (*.wi files)

[Johan Schoeman]

Hi there

Does anyone in the forum have an understanding of the Coreldraw Wavelet image format?


".......The image in the driver's license barcode seems to be encoded as based on the Coreldraw Wavelet image format at 8bit grayscale. But, little else is known about how to decode this image....."

The file data starts with 574904.... where 57 = W and 49 = I. The 04 is apparently the next number of bytes (4 in this case) that specifies the height (bytes) and width (bytes) of the Bitmap/image.

Have browsed the web "broken" but not making much sense of how to build an image/bitmap from the wavelet data.

You can take a look at the United States Patent and Trademark Office and search for applicant Corel Corporation. There certainly has to be a patent for this format since they have to cover their back in order to use it. If there is a patent then in this patent there will be a detailed description of the format. Corel Corporation is from canada and definitely there will be in the USPTO a patent. The applicant has to be Corel Corporation. If not in the USPTO then search in the institution that software copyright is set in Canada or United States.
