Yet another CFImage bug

Forum|Forum|17 years ago

Sorry for the sarcastic title, but this is the third major CFImage bug I've found in 2 weeks.... I love ColdFusion, but this is getting ridiculous.

The error occurs when writing a JPG file to disk using cfImage action="write". In our scenario, the file is uploaded by a user, then read in using cfimage action="read". The error below occurs when the file is written.

The following image will cause the error:
http://img246.imageshack.us/img246/7003/024nt5.jpg

Error:
javax.imageio.IIOException: Quantization table 0x02 was not defined at com.sun.imageio.plugins.jpeg.JPEGImageWriter.writeImage(Native Method) at com.sun.imageio.plugins.jpeg.JPEGImageWriter.write(JPEGImageWriter.java:996) at coldfusion.image.ImageWriter.writeJPeg(ImageWriter.java:60) at coldfusion.image.ImageWriter.writeImage(ImageWriter.java:119) at coldfusion.image.Image.write(Image.java:578) at coldfusion.tagext.io.ImageTag.performWrite(ImageTag.java:593)

If someone can please verify it that would be great.

One note, I have not installed the patch recommended for one of the other issues, located here:

The patch notes didn't make any mention of this problem, and I haven't had a chance to test it yet.

I confirmed too. hf801-71557.zip kb403411 fixed this issue but not the cumulative ColdFusion 8.0.1 cumulative hot fix 1.

There are two problems mentioned within this topic, the "Quantization table 0x02 was not defined" error with some jpegs and the file locking issue.

Can anyone confirm that both of these issues are resolved by installing the hot fix? I have three cf8 servers to look after and have to schedule downtime with customers to install a hot fix - I want to be sure it's worth the hassle.

Thanks

markthickpaddy,

There were a total of four issues, across several different threads:

1. Quantization table 0x02 was not defined (this thread)
2. Image files locked on error (this thread)
3. Missing Huffman code table entry
4. Files get locked by cfimage, can't delete them

So far the updated hotfix (dated 05/07/2008) has fixed all (4) of the issues for me. I noticed hans blix marked all of his threads as answered. So I would guess the hotfix worked for him as well, but confirm it with him.

I've confirmed the fix for all these issues too.

You could try messing about with temporary files to work around this - have imageWrite write to a temp file and if it succeeds, move the file to the destination, if it fails, try to delete it (which might fail, but what the hell). As far as I recall, imageCFC does this.

I like the idea of trying CF's imageWrite function first, but that's just because I'm assuming that there is some good reason why adobe chose not to use ImageIO to write the images (performance, support for more jpeg sub-types, I dunno).

markthickpaddy,

Yes, the ideal would be to use ImageWrite. However, there are several issues that appear to be related to ImageWrite, not just this one.

I did try the temp file idea, but the failed image file generated by ImageWrite could not be deleted. Not that surprising considering the "sharing violation" error I received earlier when trying to open the image with another program.

I do not know what ImageWrite uses behind the scenes. Just that there seems to be a difference between the method it uses and the one used here. Due to the fact that there are multiple issues related to ImageWrite, I am sticking with the function above for now. I will replace it with ImageWrite once the issues are resolved.

I tested the image with the patch applied. The result is the same: javax.imageio.IIOException: Quantization table 0x02 was not defined ... However, ImageIO.write is able to save this image to disk

<cfscript>
imageVariable = ImageNew( ExpandPath('024nt5.jpg') );
bi = ImageGetBufferedImage(imageVariable);
outFile = createObject("java", "java.io.File").init( ExpandPath('024nt5_savedWithImageIO.jpg') );
ImageIO = createObject("java", "javax.imageio.ImageIO");
ImageIO.write( bi, "jpeg", outFile );
</cfscript>

I assume this does not happen with every image, just certain image files? Again, while I suspect it may be a bug, without knowing more about the internals of CF's image handling, there is still a small chance that the cause may be the image file itself. I know that does not help with your current issue, but using the ImageIO.write work-around will let you to write the images to disk. At least until you have a definitive answer, one way or the other.

I also stumbled upon the exact same problem after running the cf 8.01 updater. I've added a function to my code to allow the image to be written using ImageIO or the JPEG encoder if imageWrite fails. I've attached it if anyone else wants to use it.

Thanks for the workarounds and confirmations. I've reported the bug to Adobe. Out of curiosity, has anyone tried performance testing the ImageIO method?
