ImageSharp | : camera : A modern , cross-platform , 2D Graphics | Computer Vision library

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.

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.

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:

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:

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

In c# (Windows), with the width, height and stride of an image, we can convert an Intptr to Bitmap as follows:

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

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?

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.

I did find this:
