KGy SOFT Drawing Debugger Visualizers
This package provides debugger visualizers for several System.Drawing types such as Image, Bitmap, Metafile, Icon, BitmapData, Graphics, ColorPalette, Color. It supports multi-page, multi-resolution and animated images as well as saving them in various formats.
When a type is debugged in Visual Studio and there is a debugger visualizer installed for that type, then a magnifier icon appears that you can click to open the visualizer.
Either click the magnifier icon or choose a debugger visualizer from the drop down list (if more visualizers are applicable).
If an image or icon instance is debugged in a non read-only context, then it can be modified, replaced or cleared.
Several modifications are allowed on non-read-only images such as rotating, resizing, changing pixel format with quantizing and dithering, adjusting brightness, contrast and gamma, or even editing the palette entries of indexed bitmaps.

FAQ
Q: Can I use the debugger visualizers for other Visual Studio versions?
A: The VSIX installer supports Visual Studio 2013 and newer versions (tested until 2019). However, you can install the debugger visualizers manually for any version starting with Visual Studio 2008. See the installation steps at the project site.
Q: Is Visual Studio Code supported?
A: As it has a completely different API, it is not supported yet.
Q: I get an error message when I click the magnifier icon.
A: It can have several reasons. See the Troubleshooting section at the project site.
Q: Are WPF image types supported?
A: No, these visualizers are for System.Drawing types. But the built-in Dependency Object visualizer is able to display image sources anyway.
Q: I have removed the debugger visualizer extension, and it is still working. How can I remove it completely?
A: When the extension is active it copies the visualizers into the Documents\Visual Studio <version>\Visualizers folder if it is not there. Unlike an MSI installer the VSIX packages do not support uninstall actions so this copied content will not be removed automatically. However, the extension creates also a KGy SOFT Drawing Debugger Visualizers/Manage Installations... menu item under the Tools menu where you can remove the installation from the Documents folder. So the proper way of a complete uninstall:
- Click Tools/Drawing Debugger Visualizers/Manage Installations...
- Select the current Visual Studio version and click "Remove"
- Now uninstall the extension from the Tools/Extensions and Updates... (2019: Extensions/Manage Extensions) menu. Without this last step the debugger visualizers will be automatically reinstalled when you restart Visual Studio.
