imagesharp load image from stream

This is the same functionality Dimitri described, I will just convert his code to use ImageSharp instead. In contrast, to add the CoreCompat.System.Drawing packages you have to include three different packages when writing cross-platform code - the library itself and the run time components for both Linux and OS X: Obviously, if you are running on only a single platform, then this probably won't be an issue for you, but it's something to take into consideration. (HttpWebResponse)imgRequest.GetResponse(); This method can be seen as an inline implementation of an `IImageProcessor`: (The combination of `IImageOperations.Apply()` + this could be replaced with an `IImageProcessor`). While for ImageSharp we have the following: Obviously the HttpClient code is identical here, but there is less faffing required to actually read an image from the response stream. Stay up to the date with the latest posts! We first download the image, crop it and then save it to a MemoryStream. public static Image ToImageSharpImage (System.Drawing.Bitmap bitmap) { using (var memoryStream = new MemoryStream ()) { bitmap.Save (memoryStream, System.Drawing.Imaging.ImageFormat.Jpeg); memoryStream.Seek (0, SeekOrigin.Begin); return Image.Load (memoryStream, new JpegDecoder ()); } } /// The containing image data. Better way to check if an element only exists in one array. No worries. Sponsored by MailBee.NET Objectssend, receive, process email and Outlook file formats in .NET apps.

It rotates/flips the image based on EXIF data. Thanks again. This bug still exists in 1.0.0-beta0007. /// By reading the header on the provided stream this calculates the images format type. This file contains bidirectional Unicode text that may be interpreted or compiled differently than what appears below. To retrieve image metadata, either load an image with Image.Load or use Image.Identify (this will not decode the complete image, just the metadata). For the purposes of this comparison, I'm going to start with the code presented by Dmitry in his post and convert it to use ImageSharp. By voting up you can indicate which examples are most useful and appropriate. I specified the version 1.0.0-* to fetch the latest version from the feed (1.0.0-alpha7 in my case). at ImageSharp.Image.Load[TColor](Configuration config, Stream stream, IDecoderOptions options) Learn more about bidirectional Unicode characters. This will contain the following profiles, if present in the image: ExifProfile IccProfile You can find the source code for his project on GitHub here, and the source for my version here. ImageSharp can already tell you the mimetype of the input image. var bytes = image.SavePixelData () If you are looking to convert the encoded stream as a byte [] (which I suspect is what you are looking for). so if you need a drop in replacement for System.Drawing then it's a good place to start. In contrast, the ImageSharp version of this method would look something like the following: I think you'd agree, this is much easier to understand! It accepts the posted file as a stream: using var image = Image.Load(file.OpenReadStream()); Once you get an instance of the image, you can start manipulating it using the Mutate method. The first step is to add the ImageSharp package to your project. x.Fill(graphicOptions, Rgba32.LimeGreen, corners)); then cut out of the square a circle so we are left with a corner, corner is now a corner shape positions top left, lets make 3 more positioned correctly, we can do that by translating the orgional artound the center of the image, move it across the width of the image - the width of the shape. ImageSharp offers an incredibly flexible collection of resize options that allow developers to choose sizing algorithms, sampling algorithms, and gamma handling as well as other options. This is a brand new library that is designed from the ground up to be cross-platform by using only managed-code. Colorspace transforms (RGB/CMYK/Grayscale/CIELab and many more).

(Image Image, IImageFormat Format) imf = await Image.LoadWithFormatAsync (file.OnDiskFilename); using Image img = imf.Image; img.Save (Response.Body, imf.Format); Instead of using an Enum to specify the output formatting, you pass an instance of an IImageEncoder, in this case the JpegEncoder. Now the library is installed, we can start converting the code. How is Jesus God when he sits at the right hand of the true God? Regarding interop. /// /// The specialized decoder options. Since you've registered your Middleware after the ImageSharp Middleware in Startup, the ImageSharp Middleware has already processed the request before yours intercepts the request. The biggest problem with this is that resizing an image is relatively expensive, taking multiple seconds to process large images. It just involves changing the type of the destination image to be Image (as mentioned in the previous section), and updating the last line, in which we save the image to a stream. -ImageSharp.Formats.JpegFormat This approach is more extensible, though it is slightly less discoverable then the System.Drawing approach.
