kandi X-RAY | ImageSharp Summary
ImageSharp is a new, fully featured, fully managed, cross-platform, 2D graphics library. Designed to simplify image processing, ImageSharp brings you an incredibly powerful yet beautifully simple API. ImageSharp is designed from the ground up to be flexible and extensible. The library provides API endpoints for common image processing operations and the building blocks to allow for the development of additional operations. Built against .NET Standard 2.0, ImageSharp can be used in device, cloud, and embedded/IoT scenarios.

It looks like the ImageSharp folks have been toiling away at WebP support.
This issue does a great job of describing where the progress is at:
As the title says. It seems that Avalonia Bitmap requires file path, so the only solution that comes to my mind is saving image, and then displaying it. But it's not exactly what I want to do, I would want to directly display the image from memory....
ANSWERAnswered 2022-Mar-22 at 06:04
You can save the Image's data into a memory stream and pass it in to Avalonia's Bitmap.
However, the solution won't work on linux machine since
Bitmap requires few libraries pre-installed on the system.
I've tried ImageSharp to convert the
SixLabors.ImageSharp.Image.Load(rawBytes), however, it throws
Unhandled exception. SixLabors.ImageSharp.InvalidImageContentException: PNG Image does not contain a data chunk.
Does anyone knows any alternative to achieve this.

This works fine with ImageSharp assuming Docnet works then ImageSharp will work fine for you.
The trick is you want to be using the

I'm trying to parallelize the processing of an image using ImageSharp. The documentation here: https://docs.sixlabors.com/articles/imagesharp/pixelbuffers.html has an example of processing two images in parallel with the following code:...
ANSWERAnswered 2022-Mar-09 at 03:26
I would normally recommend using our higher level pixel buffer manipulation for pixel access. While not parallel by default (the
Vector4 variant is) they're extremely efficient.
However, if you want to use parallel processing you should use
ParallelRowIterator from the
SixLabors.ImageSharp.Advanced namespace. This splits the processing into blocks based up on the number of available processors applying a user defined
IRowOperation instance to the image.
Here's a basic example applying random pixels from a source to a destination.
I'm converting ASP.NET WebForms code to ASP.NET Core Razor pages which is new to me. I'm trying to retrieve an image MemoryStream from a business class (based on SixLabors awesome ImageSharp) and have the page render the JPEG -- no HTML, just the image. I intend to use this page elsewhere as an

I think Razor pages are intented to return html content.
However it seems to be possible to return different types of result in OnGet e.g. you could return a new FileContentReset (FileStreamResult seems to have issues with contentlength)
Following the docs at the Getting Started page (although without newer language features), I have the following code:...

This turns out to have been a language version problem.
The Project was set to the default of "C# major latest version" in Advanced Build Settings (being 7.0 in VS2017).
Changing it to "C# 7.3" fixed the error message and allowed the build to succeed.
In c# (Windows), with the

I found a GitHub issue showing how to remove an Image's exif data by setting its ExifProfile to null:...
ANSWERAnswered 2022-Feb-14 at 21:48
Turns out there are two different types of metadata - EXIF and XMP. It is necessary to set both objects to null to remove them all:
I’m trying to reduce the size of photo thumbnails (100x75 px) generated with SixLabors ImageSharp, using the JpegEncoder. However the images don’t seem to vary in file size much, despite quality level used.
In my legacy System.Drawing code, when I used an ImageCodecInfo encoder and an EncoderParameter for Imaging.Encoder.Quality set to 30, I’d receive nice low-quality images — about 2k. Perfect for thumbnails.
With ImageSharp, no matter what I set the SixLabors.ImageSharp.Formats.Jpeg.JpegEncoder.Quality to, the images are always about 24k. Quality can be set 0-100, and the visible quality goes down, but the file size doesn’t dip much — even when the jpegs are comically compressed. Always about 24k.
Can anyone explain why this is? Why does an image at .Quality 5 get written to about the same size as 90, despite dramatic visible compression? Are there other properties I need to set with this encoder? Should I be using a different format for better results?...
ANSWERAnswered 2022-Feb-14 at 16:37
It was the XMP metadata. Resizing source images down to thumbnails maintains their meta collections. You must remove it prior to saving. Alternatively, use the method to extract the actual thumbnail from the metadata rather than create it new.

I am trying to extract thumbnails from source jpegs and save them to the file system, using the C# ImageSharp library. I see there is some mention of it in the intellisense for the component: SixLabors.ImageSharp.Image.Metadata.ExifProfile.CreateThumbnail()

TPixel would be any of the pixel formats in the
SixLabors.ImageSharp.PixelFormats namespace. But unless you are planning on interoperating with other systems that require the pixel data layed out in memory in specific ways you will likely just want to use

If you prefer, you can compile ImageSharp yourself (please do and help!).
Using Visual Studio 2019 Make sure you have the latest version installed Make sure you have the .NET 5 SDK installed
