Creating Icons for Custom Nodes

Custom nodes, that are the part of package, support icons.

1. Get ID of custom node. Open node with Notepad. Find its ID. It will look something like ID="4cdf5500-fe21-402e-acb7-bb9fc1b5a64b"

2. Open Visual Studio. As a template, choose Visual C# > Class Library. Create in your solution resx file, named PackageImages.resx.

3. Add to recently created file your image. Change your image name to .Small.png

4. Change icon persistence to Embedded in .resx

5. Open .csproj file. Use Notepad.
6. Uncomment BeforeBuild part.
7. Write next code:

<Target Name="BeforeBuild">`
<GetReferenceAssemblyPaths TargetFrameworkMoniker=".NETFramework, Version=v2.0">`
<Output TaskParameter="FullFrameworkReferenceAssemblyPaths" PropertyName="FrameworkAssembliesPath" />`
</GetReferenceAssemblyPaths>`
<GenerateResource UseSourcePath="true" Sources="$(ProjectDir)PackageImages.resx"` 
  OutputResources="$(ProjectDir)PackageImages.resources"` 
  References="$(FrameworkAssembliesPath)System.Drawing.dll" />`
<AL TargetType="library" EmbedResources="$(ProjectDir)PackageImages.resources"`
OutputAssembly="$(OutDir)Package.customization.dll" />`
</Target>

8. Rebuild your project. Package.customization.dll will be in project's output folder.

9. Add Package.customization.dll to your package.

NB! Default icon

You can add default icon, if you want to use 1 icon for all custom nodes. You have to make all steps, described above. But name of your icon should be DefaultCustomNode.Small

##Extracting a large number of node IDs If your package contains a large number of nodes you can use this script to automatically extract the IDs of all nodes in a given directory: https://raw.githubusercontent.com/CAAD-RWTH/ClockworkForDynamo/master/workflow_samples/0.7.x/ExtractNodeIDs/ExtractNodeIDs.dyn
