I am having issues converting a png to tiff. The conversion goes fine, but the image is huge. I think the issue is that I am not doing the compression correctly? Anyone h

    I don't know Java IO, but generally you want to look at a few things

    1. Can you use JPEG compression instead of LZW?
    2. See how to set the TIFF strip size -- if small size is what you want, set it to the height of the image.

    Edit: Looks like a TiffWriteParam has the following methods

    tiffWriteParam.setTilingMode(ImageWriteParam.MODE_EXPLICIT);
    tiffWriteParam.setTiling(imageWidth, imageHeight, 0, 0);
    

    set the imageWidth and imageHeight vars to your image's size. The downside is that it will be slower to read out regions of the image.
