Read huge jpg file ,get error: javax.imageio.IIOException: Can not read image of the size 54948 by 45620 about twelvemonkeys HOT 2 CLOSED

Sorry to bother you

I solved it by implementation 'com.twelvemonkeys.imageio:imageio-jpeg:3.9.4' in gradle .

I read tiff file by implementation 'com.twelvemonkeys.imageio:imageio-tiff:3.9.4' in gradle, because tiff file type is not suported by origin ImageIO. And I do not import com.twelvemonkeys.imageio:imageio-jpeg:3.9.4, because Jpeg is supported by origin ImageIO and It make error.
I guess com.twelvemonkeys.imageio:imageio-jpeg:3.9.4' has made some optimization for read jpeg file .

When reading huge picture,I am wonder whether it is necessary to import specail plugin for specail file type? For example, import com.twelvemonkeys.imageio:imageio-bmp:3.9.4 for BMP file type.

Thanks

Hi,

No worries! Glad you found a solution!

I think there was/is a bug in the JDK code for how the maximum size is computed (in javax.imageio.ImageReader#getDestination), so I have a different way of computing it, taking subsampling and/or tiling into account. The JDK version only verifies against the original dimensions of the file. There might be similar issues for other formats, though I believe BMP files that large is quite rare.
