report deflate decoding bug (see: 51720a8)
improve performance of decoders at 1.1x - 2.5x (see: 1b32629)

* Update metadata names * Use WithIterationCount * Format Benchmark documents * Update copyright assignment to Six Labors & Contributors * Update deps * React to Benchmark library update

- ResizeWindow -> ResizeWorker - Most logic moved to ResizeWorker

which has been renamed from CalculateResizeWorkerWindowCount()

…nit-tests for Tiff decoder.

…s#979) * remove some redundant constructor overloads from exceptions * re add ImageProcessingException ctor only used in release

… tiff-codec # Conflicts: # src/ImageSharp/Configuration.cs # src/ImageSharp/PixelFormats/PixelBlenders/DefaultPixelBlenders.Generated.cs # src/ImageSharp/PixelFormats/PixelBlenders/DefaultPixelBlenders.Generated.tt # src/ImageSharp/PixelFormats/PixelBlender{TPixel}.cs # tests/ImageSharp.Tests/ConfigurationTests.cs

Correct Metadata updated name (for Resolution properties), temporary disable tiff native metadata properties.

@Sergio0694 can you help a bit? Doest the bokeh blur processor + test code look up to date on this branch?

EDIT:
Or does it need a submodule update to get the latest reference images?

James-Jackson-South · 2019-08-23T03:55:14Z

@antonfirsov @Sergio0694 I can have a look, I'm familiar with that code also now.

IldarKhayrutdinov · 2019-08-23T07:26:02Z

@antonfirsov @Sergio0694 Thanks! Really I forgot to update submodules 😃
@antonfirsov @James-Jackson-South @Andy-Wilkinson Now I have passed the tests locally and I expect that on the CI will pass. Please code review.
I continue to work on Tiff format, soon I will prepare new PR.

Sergio0694 · 2019-08-23T09:59:47Z

Thanks @James-Jackson-South!
@antonfirsov I think James is actually more familiar than me with the tests part of the bokeh blur processor actually, as he kindly set that part up after I finished working on the last tweaks for the processor itself 😄

1198 files! Crikey!

I'll do a folder check via BeyondCompare before digging through the diff. Everything should be identical except for the new Tiff code.

Sure, the most of changes are merge from master.

antonfirsov · 2019-08-24T21:09:06Z

@James-Jackson-South since this is not going into main, I think we can merge it as-is as soon as the tests in TiffDecoderTests are matching the current capabilities of the decoder.

I see a few improvement points, but I don't think it's a good idea to address them in this huge PR, let's do them later:

Using MemoryAllocator and disposable buffers instead of ArrayPool.Shared
Consider sharing code with other decoders. Eg. TiffLzwDecoder looks pretty much the same as SixLabors.ImageSharp.Formats.Gif.LzwDecoder

antonfirsov · 2019-08-24T21:20:50Z

@James-Jackson-South see #988 for the diff.

JimBobSquarePants · 2019-08-25T02:32:00Z

Thanks, I’ll have a look later today. 👍

JimBobSquarePants · 2019-08-25T13:34:59Z

Looks good to me. Will merge now.
