Error while reading dicom file

KristinWang opened this issue 6 years ago · 6 comments

Hi there,

I was trying to load a dicom file through papaya. But it gave an error saying 'offset is outside the bounds of DataView", at line "Daikon.tag.getFloat64()".

Inside this function, the boundary of the FOR loop, is smaller than '1' (in this case, m=0.5), while the iterator 'u' starts from '0', and increment is '1'. So in this case, the line 'a.getFloat64()' throw an error.

I wonder, isn't it reasonable to do Math.floor() on the 'm' ? Any ideas on this would be appreciated!

Thanks,
Kristin

For m to be 0.5, something really must have gone wrong. m should always be a whole number and a.byteLength some multiple of 8. If you can share with me an example image that demonstrates that issue we can get it fixed. Thanks.

Hi. I'm sorry but I never received any email from you. I'm not sure which email GitHub shows. If it's my university email, it might have gotten filtered if you included code in the email content. To email me directly please use: michaeljohnmartinez@gmail.com . Thanks.

Hi, I have sent you an email to your gmail (sample images were attached) two days ago. If you didn't receive any email again, please let me know so that I can try to send you the images in other way.
Thanks very much.

Ok, this should be fixed now. It was more of a data issue than anything else. There were two tags that had a Float Double type but were less than 8 bytes, which isn't valid. I added a check for this such that if the value length is less than 8, it returns 0.
