I wanted o know whether it’s possible to compress a given image to a predefined size in apache POI.
Say I have an input image of 500X500, and I want to convert to a thumbnail size (40X40), can I do it in apache POI?

if not, does java library provide any image processing capabilities?

Right now, I was able to embed images using apache POI, but I have no control over forcing the image to be with in a certain cell size.

Thanks.

    The Picture interface in POI has resize methods as in the Javadocs

    void resize(double scale)

    Parameters:

    scale – the amount by which image dimensions are multiplied relative
    to the original size. resize(1.0) sets the original size, resize(0.5)
    resize to 50% of the original, resize(2.0) resizes to 200% of the
    original.

    Use either the HSSFPicture or XSSFPicture implementations
