Aspose.Drawing vs System.Drawing.Common

Aspose.Imaging Product Family
#1

Hi
I have created a simple .NET 6.0 application to convert an image to PDF.
For this I use Aspose.Drawing instead of System.Drawing.Common.

But when I run the application, I get an error: Unhandled exception. System.IO.FileNotFoundException: Could not load file or assembly ‘System.Drawing.Common, Version=5.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51’. The specified file cannot be found.
File name: ‘System.Drawing.Common, Version=5.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51’
at Aspose.Imaging.Image.#=zdhS8Vtln7VSf(StreamContainer #=z9ROXOM6FvRVD, LoadOptions #=zYCOM1eZ$0uII)
at Aspose.Imaging.Image.Load(String filePath)
at Program.$(String[] args) in C:\Users\Yura\Documents\Visual Studio 2022\Projects\ConsoleApp1\ConsoleApp1\Program.cs:line 7

What have I done wrong?

If I use Aspose.PDF instead of Aspose.Imaging to insert images, then the error is the same.

                    using (var pdf = new Aspose.Pdf.Document())
                    {
                        using (var bitmap = new Bitmap(input))
                        {

@PoweRDeaD, Aspose.Imaging has version that supports Aspose.Drawing as default graphics engine it is available here https://www.nuget.org/packages/Aspose.Imaging/22.10.0-beta and you can try it. If your question is related to usage of Aspose.PDF with Aspose.Drawing you can ask this question in PDF related forum https://forum.aspose.com/c/pdf/10

Ok.

If I use Aspose.Drawing and Aspose.Imaging in the same project:

<PackageReference Include="Aspose.Drawing" Version="22.11.0" />
<PackageReference Include="Aspose.Imaging" Version="22.10.0-beta" />

I get an error:

Aspose.Imaging.CoreExceptions.ImageLoadException: Image loading failed.

Using ‘Aspose.Drawing’ version 22.6.0 helped me:

<PackageReference Include="Aspose.Drawing" Version="22.6.0" />
<PackageReference Include="Aspose.Imaging" Version="22.10.0-beta" />

@PoweRDeaD, thank you for information. Please note, that we have plans to release Aspose.Imaging for .NET7 in Apr-May 2023, which will contain Aspose.Drawing as default graphics engine.
