Importing a JPEG image to excel as matrix

[qia li]

HI guys,
Is there a way to convert a JPEG image into a matrix of integers (code
index)?

Thanks

You may be able to use your scanner's OCR program if it can read .jpg files.

If it can't, maybe you could print it and then scan it and then use the OCR program.

Either way, I'd invest a lot of time checking that data. I've never seen an OCR
program that was 100% accurate.

I am actually trying to write a OCR program in excel, but as the first
step I need to import the image into my program, individual point and
the corresponding color index.
Anyone could advise?
Thanks

The question as posed is ambiguous, but assuming the OP wants to load
the red, green and blue components of a JPEG image into Excel then the
simple answer is no. The slightly longer answer is to save the JPEG file
as a windows BMP file and then load that image into Excel.

XL2003 and earlier the shortest dimension must be < 256.
XL2007 removes this limitation but will be glacially slow.
