            It looks like the ImageSharp folks have been toiling away at WebP support.

            Display ImageSharp Image in Avalonia UI
            Asked 2022-Mar-22 at 06:04

            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.



            Answered 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.



            System.Drawing.Common.Bitmap cross platform alternatives
            Asked 2022-Mar-15 at 16:00

            I am looking to convert PDF files into images. Docnet is able to convert the pdf into bytes[] and their samples show how to save this byte[] into an image file using Bitmap. Documentation

            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 byte[] using 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.

            PS - I'm open to explore any other cross platform FREE supported alternatives to convert PDF files to images.



            Answered 2022-Mar-15 at 16:00

            This works fine with ImageSharp assuming Docnet works then ImageSharp will work fine for you.

            The trick is you want to be using the Image.LoadPixelData(rawBytes, width, height); API not the Image.Load(encodedBytes); one.



            Right way to parallelize pixel access across multiple images using ImageSharp
            Asked 2022-Mar-10 at 15:13

            I'm trying to parallelize the processing of an image using ImageSharp. The documentation here: has an example of processing two images in parallel with the following code:



            Answered 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.



            How do I write an image's MemoryStream to the page body?
            Asked 2022-Mar-08 at 14:18

            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 src, like

            In Render.cshtml.cs:



            Answered 2022-Mar-07 at 21:07

            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)



            How to new an Image with ImageSharp 2.0.0 in VS2017
            Asked 2022-Feb-26 at 12:12

            Following the docs at the Getting Started page (although without newer language features), I have the following code:



            Answered 2022-Feb-26 at 12:10

            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.

            (Guessing that it relates to the unmanaged constraint added in that version - it's not mentioned by name in the version history, but is in this blog post.)

            How do I clear an Image's EXIF data with ImageSharp?
            Asked 2022-Feb-14 at 21:48

            I found a GitHub issue showing how to remove an Image's exif data by setting its ExifProfile to null:



            Answered 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:



            Why does file size remain static despite ImageSharp JpegEncoder.Quality setting?
            Asked 2022-Feb-14 at 16:37

            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?



            Answered 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()

            ...but I can't seem to find any documentation for it or examples to call it correctly.

            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 Rgba32
