Imageprocessor: ImageFormatException: Unknown component selector
Hi,
I'm trying to add an image processing functionality to my ASP.NET Core project, and I'm getting the following exception while attempting to create a new Image instance:

Ways to reproduce:
- Download a profile picture from FB.
- Instantiating a new Image:
using (var stream = System.IO.File.OpenRead(@"C:\Users\gbyah\Desktop\foo.jpg"))
{
//return File(buffer, "image/jpeg");
var image = new Image(stream);
}
I've tested the code with the images attached to the project samples, and they do work correctly. I'm wonering maybe Facebook images lack of some meta information?

Hi there,
Thanks for this.
It seems that within the images saved by Facebook there are multiple SOS (Start of scan) markers. This will be due to the images being saved in progressive format.
Oddly when parsing the second marker the ProcessSOS method returns the number of components as 1, previous scans are 3. I've been reading about and it looks to me like LibJpeg.NET uses similar logic.
@mweber26 Could you please compare our version to the golang to see if they suffer the same issue? I don't know how to do that.
Cheers

JPEGsnoop output of this image.
It's this marker that seems to be throwing everything out of whack. I'm going to investigate a better way to identify the huffman tables.

PLEASE ADD TO DATABASE with [Tools->Add Camera to DB]
Progressive does appear to be in the golang version. I will fix and submit a pull request.

Thank you guys for the fast responses and dedicated work! You're awesome!

Ok -- found the first problem. There was a problem with the go conversion. I have fixed that but the image still doesn't decode. I will continue to search for the problem.
I have verified that the image does work with golang. So I just have to track down the conversion error I made.

This image decoding is fixed with #351
I have another sample image (http://www.reasoft.com/tutorials/web/img/progress.jpg) that fails though -- still looking at that.

Excellent! @YahavGB I've merged those fixes in and tested against both images. Everything now works as expected.
Much appreciated @mweber26. I'm gonna have a good dig through those classes to get a much better understanding of what is going on.

It's not that complicated. I'm not sure you would have found these bugs since they were just golang conversion issues and without reviewing the go source I don't think they would be obvious. But you can certainly learn a lot about jpeg from that code now.

Definitely! I'm going to be refactoring a few things to more closely match my style and add a lot of commenting for other developers. I've got a great book which goes through the entire spec in great detail.

Hi
I'm trying to use an image processing in my ASP.NET Core. I am uploading images from web as stream. With some images is ok, but with other is not. I have newest version from repo.
Image image = new Image(stream);
Exception message: "Bad RST marker"
Stack trace:
w ImageProcessorCore.Formats.JpegDecoderCore.ProcessSOS(Int32 n)
w ImageProcessorCore.Formats.JpegDecoderCore.Decode(Stream stream, ImageBase image, Boolean configOnly)

w ImageProcessorCore.Image.Load(Stream stream, IList`1 formats)
w ImageProcessorCore.Image..ctor(Stream stream, IImageFormat[] formats)

For png

Any ideas pls?

For the jpeg image, we will need a copy of the jpeg you are trying to open.

Thx a lot. Now it works. Do you have any idea about png?

@ArturGol That looks like a reference error in your solution to me. I can't download your png to test, it keeps timing out.
