How do I access layers from a C++ plugin?

To my knowledge, accessing individual layers is possible only from automation plugin but it cannot access individual pixels.

But automation plugin can call other plugins. Take a look at automationfilter example in SDK.

It calls filter plugin “hidden” also from SDK which can access pixels.

Hope this helps,

The ExportRecord of the plugin type contains a pointer to the documentInfo.

The layerDescriptor can then be iterated over for every layer in the document.

You can use the ChannelPortsProcs to read the data from those layers.
