Photoshop 24.2 (February 2023)

Imaging API Beta

We are excited to provide an entirely new capability with the Imaging API. Anyone that has been eagerly awaiting the ability to directly get and set pixels in a document should head to the dedicated page. Note: we are serious about the Beta label. While this is exciting new territory, keep in mind that the API is in an early form. We want your feedback to help guide it toward maturity.

Text support

The UXP DOM features a variety of new text-related APIs, that provide a more robust and consistent experience for developers. Instead of aiming for ExtendScript parity, the UXP DOM has been designed to provide a more modern and intuitive API surface. While still providing the old functionality, it's been extended to cover many features that weren't previously available.

  • A Document.createTextLayer method was added, which allows developers to create a new text layer in a document. It accepts a TextLayerCreateOptions object, which can be used to set the initial text content, style, and other properties.
  • The textItem property of a Text Layer is the entrypoint for everything text-related. It provides direct access to a few properties and methods:
    • contents
    • isParagraphText
    • isPointText
    • orientation
    • textClickPoint
    • convertToParagraphText()
    • convertToPointText()
    • convertToShape()
    • createWorkPath()
  • Properties and methods related to features made available by Photoshop in the Character palette are now grouped in the textItem.characterStyle object:

Other fixes

  • solidColor.cmyk no longer shows undefined for yellow color. Also setter is now fixed.
  • SolidColor - Adds range validation for all color modes and its components so it should not be possible to enter invalid value. This should also fix invalid hex code value.
  • Adds setter to the app.backgroundColor so it can be changed.
  • app.backgroundColor and app.foregroundColor were broken when color was was not picked as RGB color*
  • RGB32 is currently not supported. If RGB 32 bit per channel is obtained, it will be converted automatically into nearest RGB 16 bit per channel.

UXP v6.5 Integration

New

Photoshop 24.1 (December 2022)

app.getColorProfiles

Color profiles are needed for the Imaging API, so a new method on the app is introduced to return profile names. At this time, only profiles for RGB and Gray are available.

CountItems support

The CountItems DOM API is now available in Photoshop.

  • The CountItems collection behaves like other collections at the Document level in the API. CountItems further support the following properties and methods:
    • typename, length, parent.
    • add(), removeAll(), getAll(), createGroup(), renameActiveGroup(), removeGroupByIndex(), toggleActiveGroupVisibility(), activateGroupByIndex(), setActiveMarkerSize(), setActiveLabelSize(), setActiveColor().

Other fixes

We now throw errors in more situations with layer blend modes

  • Passing a value that is not in Constants.blendMode.

  • Passing a blend mode that is not compatible with the document's color mode or bit depth. Previously, this call would fail silently.

  • Attempting to set the blend mode on the Background layer. Previously, doing so would convert Background to a regular layer and generate a new layer ID. Automatic Background promotion is undesirable as a side effect in this case. This action is not available via the UI.

  • The CountItem class implements the following properties and methods:

    • typename, parent, itemIndex, groupIndex, position
    • move(), remove()

UXP v6.4 Integration

New

Bugs Fixes

  • Provide an API to programmatically close dialog in pop-out/theatre mode.
  • Plugin Data folder shouldn't be created for scripts
  • Crash on exit
  • script.setResult("kSuccess") not working
  • Resource Leaks in Window Dialog on UWP
  • Privilege plugin fail to add in XD in certain cases
  • Fixed mouse/keyboard events within Webview in XD v55 and Win 10.

Photoshop 24.0 (October 2022)

Preferences

Adds API to change some of the Photoshop preferences. Only first set of 38 preferences was added. More will follow.

ColorSamplers support

The ColorSampler DOM API is now available in Photoshop.

  • The ColorSamplers collection behaves like other collections at the Document level in the API. ColorSamplers further supports the following methods:
    • colorSamplers.add()
    • colorSamplers.removeAll()
  • The ColorSamplers class implements the following properties and methods:
    • typename: String
    • parent: Document
    • position: {x: number, y: number}
    • color: SolidColor
    • move({x: number, y: number})
    • remove()
  • The Document class implements a new sampleColor() method that samples an {x, y} position on the fly, returning a SolidColor object without the need to create a ColorSampler object.

Layer Comps support

  • Document.layerComps property is now added, giving access to similar APIs from ExtendScript to work with layer comps.
  • LayerComps collection
    • Adds the following Layer Comp methods: add(), removeAll(), getByName()
    • Create new layer comps in the document using LayerComps.add() method. Constructors for them can be found in app object.

  • PathItem.subPathItems provides the collection class SubPathItems, which is a collection of SubPathItem objects.
  • SubPathItem.pathPoints provides the collection class PathPoints, which is a collection of PathPoint objects.
  • Create new paths in the document using PathItems.add method by providing PathPointInfo and SubPathInfo objects. Constructors for them can be found in app object.

Load on Launch support

You can now set your plugin manifest to load your plugin on app launch. See Photoshop Manifest for details.

batchPlay development helper: Copy as Javascript

It is now possible to use the Photoshop Actions panel to help build your plugin. Record valid actions, and let Photoshop generate readable and valid batchPlay to use in your UXP plugin. See the batchPlay documentation under "Accepted action descriptors".

Core event: "userIdle"

This event is generated when Photoshop detects that a user becomes idle, while Photoshop is the foreground application. A plugin must specify a number of idle seconds, and then may choose to batch process-intensive tasks. See photoshopCore.

Interactive Mode for executeAsModal

As an alternative to a UI-blocking progress bar when a plugin is within a Modal Execution scope, interactiveMode can be requested to allow for user interaction in specific circumstances. See Interactive Mode.

Photoshop 23.2 (February 2022)

  • Core Module: setExecutionMode()
  • Core Module: getPluginInfo()

Photoshop 23.1 (December 2022)

Document.suspendHistory

This API wraps around core.executeAsModal within a single document to make it easier for you to run your code under a single history state. Unlike it's ExtendScript predecessor, this method takes a Javascript function, rather than a script string.

Layer Move APIs

  • Arrange layers with layer.move(targetLayer, Constants.ElementPlacement). Added Constants.ElementPlacement for moving layers: "placeAfter" (place below a layer, below group if group layer), "placeBefore" (place above a layer, above group if group layer), and "placeInside" (inside group layers only).
  • Send a layer to the back or bring a layer to the front with layer.sendToBack() and layer.bringToFront(). If layer is within a group, the commands will operate within that group.

Adobe Photoshop Prerelease Build 61: Jun 24, 2021 (22.5)

Updated DOM API

  • New Layers collection, the old layerTree object is now called layers but as a collection using the JavaScript Proxy object. See below for introduction of collections. The old layers behavior is no longer part of the DOM. Most scripts can be updated to replace layerTree with layers. A document and a layer, if the layer kind is group, will have a valid layers collection. A pixel layer will have null for the layers property. A collection has the same semantics as an Array. The additional ExtendScript routines of add and getByName are also available. Use LayerKind.GROUP on a layer to see if any layers are available.
  • GroupLayer has been removed. Use activeLayer.kind === LayerKind.GROUP instead.
  • Constants.LayerKind, similar to ExtendScript version, but with "group" layer addition.
  • Layer APIs
    • new locked, read-only way to tell if any of the properties are locked
    • allLocked, pixelsLocked, positionLocked, transparentPixelsLocked properties
    • Some existing properties exposed in documentation

Adobe Photoshop Prerelease Build 60: Jun 10, 2021 (22.5)

This update contains changes that were made since the MAX 2020 (Adobe Photoshop 22.0) release.

Breaking changes

To use the new set of APIs, your project's manifest.json must be updated to include the following under the host object:

Copied to your clipboard
    "data" : {
        "apiVersion": 2
    }

Further, your manifest.json must use version 4:

Copied to your clipboard
  "manifestVersion": 4

To roll back to the MAX 2020 version of the Photoshop DOM API, set the apiVersion to 1.

Updated DOM API

  • Collections
    • We're introducing collection classes built using Proxies, to make it easier to interact with the DOM.
    • Try iterating through all the documents as such: app.documents.forEach(h => console.log(h.title));
  • HistoryStates collections and HistoryState API
    • We've built HistoryStates to mirror ExtendScript functionality. length, parent, and getByName(name) are provided. You can also use indices as such: activeDocument.historyStates[2].
    • HistoryState provides name, parent, snapshot.
  • Documents collections
    • Documents also follows ExtendScript functionality. length, add, getByName(name), parent are provided.
  • Constants module, collecting all enumerations and constants used in DOM API. Accessible via require("photoshop").constants.
  • Updated app.createDocument / app.add
    • Create a document with no params for a default document, with a predefined preset, or by providing a host of DocumentCreateOptions).
  • Updated document.save and document.saveAs
    • save no longer infers the file type from the requested file name. Instead, it invokes a save dialog for unsaved files, and performs a save operation for saved, modified files.
    • saveAs is provided for bmp, gif, jpg, png, psb, psd formats. Use SaveOptions objects to request specific saves (e.g. PhotoshopSaveOptions).
  • layer.id getter
  • Updated document.createLayer and document.createLayerGroup
    • With respective Create options: LayerCreateOptions and GroupLayerCreateOptions.
    • Collection access updates for Layer and Layer-like items are planned for upcoming releases.

Photoshop Core updates

  • Execute as Modal allows you to create plugins that can be guaranteed exclusive control over Photoshop during execution. It further allows for clear user feedback when this is occuring, and allows plugins to suspendHistory and resumeHistory.
