Imageprocessor: CloudImageService - Image larger when no querystring in set (both png and jpg)

[alecrt]

Description

Hi,

i'm facing the following issue:

Original image: 97KB
https://macroluxproduction.blob.core.windows.net/catalog/5ae70c760a902e3090234da1/images/800*800-2.jpg

Through ImageProcessingModule: 128KB
http://cdnmacrolux.flyweb.it/media/5ae70c760a902e3090234da1/images/800*800-2.jpg

From your source code i found a simple Stream.CopyTo when image has no querystring so should not be processed at all and saved to disk as is. Am I correct?

What's even more weird is that all images with original size lower than 128KB grow to exactly 128KB after being processed by the httpmodule; images bigger than 128KB grow to 1.0MB!!
Here it's an example:
https://macroluxproduction.blob.core.windows.net/catalog/5ae70c760a902e3090234da1/images/800800.jpg
http://cdnmacrolux.flyweb.it/media/5ae70c760a902e3090234da1/images/800800.jpg

Steps to Reproduce

I can share the project GIT with you if required (on bitbucket)

Why did you delete the issue template? How am I supposed to determine what version you are using etc?

Sorry @JimBobSquarePants, my mistake.
I've update the issue using your template.

Thank you

Thanks for adding the extra detail. I've figured out what is going wrong and will have a fix deployed in the next few days.

Cheers!

Oh!
You were getting the full buffer chunk instead of picture’s bytes only. That was the problem!

Thank you man, great libraries

Thanks,

Yeah since the stream could grab a buffer of any potential length to satisfy the request.

Hi James,

any ETA for the nuget package?

Thank you,

When it's ready. I'm not a robot.
