.NET5 notice:

You need update your apps to use :

System.Drawing.Common Version=“5.0.0” System.Text.Encoding.CodePages Version=“5.0.0”

if you use reference to Aspose.Imaging.dll rather than nuget reference.

Public API changes:

Added APIs:

Method Aspose.Imaging.FileFormats.Apng.ApngImage.GetDefaultOptions(System.Object[])

Method Aspose.Imaging.FileFormats.Apng.ApngImage.GetModifyDate(System.Boolean)

Method Aspose.Imaging.FileFormats.Apng.ApngImage.GetOriginalOptions

Removed APIs:

Usage Examples:

IMAGINGNET-4480 Resizing the image crops the output image

    Console.WriteLine("Starting resize of " + inputFile + " (" + image.Width + "x" + image.Height + ") to " + newWidth + "px width...");
    image.ResizeWidthProportionally(newWidth);

    // saving result
    image.Save(inputPath + outputFile);
    Console.WriteLine("File resized into : " + outputFile + " (" + image.Width + "x" + image.Height + ")");
