+# Photoshop Integration
+
+## Setup
+
+The Photoshop integration requires two components to work; `extension` and `server`.
+
+### Extension
+
+To install the extension download [Extension Manager Command Line tool (ExManCmd)](https://github.com/Adobe-CEP/Getting-Started-guides/tree/master/Package%20Distribute%20Install#option-2---exmancmd).
+
+```
+ExManCmd /install {path to avalon-core}\avalon\photoshop\extension.zxp
+```
+
+### Server
+
+The easiest way to get the server and Photoshop launch is with:
+
+```
+python -c ^"import avalon.photoshop;avalon.photoshop.launch(""C:\Program Files\Adobe\Adobe Photoshop 2020\Photoshop.exe"")^"
+```
+
+`avalon.photoshop.launch` launches the application and server, and also closes the server when Photoshop exists.
+
+## Usage
+
+The Photoshop extension can be found under `Window > Extensions > Avalon`. Once launched you should be presented with a panel like this:
+
+![Avalon Panel](panel.PNG "Avalon Panel")
+
+
+## Developing
+
+### Extension
+When developing the extension you can load it [unsigned](https://github.com/Adobe-CEP/CEP-Resources/blob/master/CEP_9.x/Documentation/CEP%209.0%20HTML%20Extension%20Cookbook.md#debugging-unsigned-extensions).
+
+When signing the extension you can use this [guide](https://github.com/Adobe-CEP/Getting-Started-guides/tree/master/Package%20Distribute%20Install#package-distribute-install-guide).
+
+```
+ZXPSignCmd -selfSignedCert NA NA Avalon Avalon-Photoshop avalon extension.p12
+ZXPSignCmd -sign {path to avalon-core}\avalon\photoshop\extension {path to avalon-core}\avalon\photoshop\extension.zxp extension.p12 avalon
+```
+
+### Plugin Examples
+
+These plugins were made with the [polly config](https://github.com/mindbender-studio/config). To fully integrate and load, you will have to use this config and add `image` to the [integration plugin](https://github.com/mindbender-studio/config/blob/master/polly/plugins/publish/integrate_asset.py).
+
+#### Creator Plugin
+```python
+from avalon import photoshop
+
+
+class CreateImage(photoshop.Creator):
+ """Image folder for publish."""
+
+ name = "imageDefault"
+ label = "Image"
+ family = "image"
+
+ def __init__(self, *args, **kwargs):
+ super(CreateImage, self).__init__(*args, **kwargs)
+```
+
+#### Collector Plugin
+```python
+import pythoncom
+
+import pyblish.api
+
+
+class CollectInstances(pyblish.api.ContextPlugin):
+ """Gather instances by LayerSet and file metadata
+
+ This collector takes into account assets that are associated with
+ an LayerSet and marked with a unique identifier;
+
+ Identifier:
+ id (str): "pyblish.avalon.instance"
+ """
+
+ label = "Instances"
+ order = pyblish.api.CollectorOrder
+ hosts = ["photoshop"]
+ families_mapping = {
+ "image": []
+ }
+
+ def process(self, context):
+ # Necessary call when running in a different thread which pyblish-qml
+ # can be.
+ pythoncom.CoInitialize()
+
+ photoshop_client = PhotoshopClientStub()
+ layers = photoshop_client.get_layers()
+ layers_meta = photoshop_client.get_layers_metadata()
+ for layer in layers:
+ layer_data = photoshop_client.read(layer, layers_meta)
+
+ # Skip layers without metadata.
+ if layer_data is None:
+ continue
+
+ # Skip containers.
+ if "container" in layer_data["id"]:
+ continue
+
+ # child_layers = [*layer.Layers]
+ # self.log.debug("child_layers {}".format(child_layers))
+ # if not child_layers:
+ # self.log.info("%s skipped, it was empty." % layer.Name)
+ # continue
+
+ instance = context.create_instance(layer.name)
+ instance.append(layer)
+ instance.data.update(layer_data)
+ instance.data["families"] = self.families_mapping[
+ layer_data["family"]
+ ]
+ instance.data["publish"] = layer.visible
+
+ # Produce diagnostic message for any graphical
+ # user interface interested in visualising it.
+ self.log.info("Found: \"%s\" " % instance.data["name"])
+```
+
+#### Extractor Plugin
+```python
+import os
+
+import openpype.api
+from avalon import photoshop
+
+
+class ExtractImage(openpype.api.Extractor):
+ """Produce a flattened image file from instance
+
+ This plug-in takes into account only the layers in the group.
+ """
+
+ label = "Extract Image"
+ hosts = ["photoshop"]
+ families = ["image"]
+ formats = ["png", "jpg"]
+
+ def process(self, instance):
+
+ staging_dir = self.staging_dir(instance)
+ self.log.info("Outputting image to {}".format(staging_dir))
+
+ # Perform extraction
+ stub = photoshop.stub()
+ files = {}
+ with photoshop.maintained_selection():
+ self.log.info("Extracting %s" % str(list(instance)))
+ with photoshop.maintained_visibility():
+ # Hide all other layers.
+ extract_ids = set([ll.id for ll in stub.
+ get_layers_in_layers([instance[0]])])
+
+ for layer in stub.get_layers():
+ # limit unnecessary calls to client
+ if layer.visible and layer.id not in extract_ids:
+ stub.set_visible(layer.id, False)
+
+ save_options = []
+ if "png" in self.formats:
+ save_options.append('png')
+ if "jpg" in self.formats:
+ save_options.append('jpg')
+
+ file_basename = os.path.splitext(
+ stub.get_active_document_name()
+ )[0]
+ for extension in save_options:
+ _filename = "{}.{}".format(file_basename, extension)
+ files[extension] = _filename
+
+ full_filename = os.path.join(staging_dir, _filename)
+ stub.saveAs(full_filename, extension, True)
+
+ representations = []
+ for extension, filename in files.items():
+ representations.append({
+ "name": extension,
+ "ext": extension,
+ "files": filename,
+ "stagingDir": staging_dir
+ })
+ instance.data["representations"] = representations
+ instance.data["stagingDir"] = staging_dir
+
+ self.log.info(f"Extracted {instance} to {staging_dir}")
+```
+
+#### Loader Plugin
+```python
+from avalon import api, photoshop
+
+stub = photoshop.stub()
+
+
+class ImageLoader(api.Loader):
+ """Load images
+
+ Stores the imported asset in a container named after the asset.
+ """
+
+ families = ["image"]
+ representations = ["*"]
+
+ def load(self, context, name=None, namespace=None, data=None):
+ with photoshop.maintained_selection():
+ layer = stub.import_smart_object(self.fname)
+
+ self[:] = [layer]
+
+ return photoshop.containerise(
+ name,
+ namespace,
+ layer,
+ context,
+ self.__class__.__name__
+ )
+
+ def update(self, container, representation):
+ layer = container.pop("layer")
+
+ with photoshop.maintained_selection():
+ stub.replace_smart_object(
+ layer, api.get_representation_path(representation)
+ )
+
+ stub.imprint(
+ layer, {"representation": str(representation["_id"])}
+ )
+
+ def remove(self, container):
+ container["layer"].Delete()
+
+ def switch(self, container, representation):
+ self.update(container, representation)
+```
+For easier debugging of Javascript:
+https://community.adobe.com/t5/download-install/adobe-extension-debuger-problem/td-p/10911704?page=1
+Add --enable-blink-features=ShadowDOMV0,CustomElementsV0 when starting Chrome
+then localhost:8078 (port set in `photoshop\extension\.debug`)
+
+Or use Visual Studio Code https://medium.com/adobetech/extendscript-debugger-for-visual-studio-code-public-release-a2ff6161fa01 
+
+Or install CEF client from https://github.com/Adobe-CEP/CEP-Resources/tree/master/CEP_9.x
