photoshopCore

The module that allows access to specialized commands within the application. Various application state can be modified or queried here.

var PhotoshopCore = require('photoshop').core;
CopyCopied to your clipboard
var PhotoshopCore = require('photoshop').core;

Variables#

apiVersion#

• Let apiVersion: number

API Version declared by the plugin's manifest.json under host.data.apiVersion field.

If value 1, you will have access to Photoshop 22.0 DOM and be able to make mutable calls outside a modal state. If 2, you will have access to latest DOM, modal execution and everything else new we're adding.

Functions#

addNotificationListener#

Promise<void>

Attach a listener to a Photoshop core event. A callback in the form of (eventName: string, descriptor: Descriptor) => void will be performed. The event(s) below are supported:

group: 'UI', event: 'userIdle'

• Invoked after the Photoshop user idles for a specified number of seconds. See setUserIdleTime.
• Invoked a second time with the descriptor {idleEnd: true} if the user is no longer idle. This signal can be used to finish up tasks being performed during the idle time.

await PhotoshopCore.addNotificationListener('UI', ['userIdle'], onUserIdle)
CopyCopied to your clipboard
await PhotoshopCore.addNotificationListener('UI', ['userIdle'], onUserIdle)

Parameters#

calculateDialogSize#

Promise<{ height: number ; width: number }>

Returns the effective size of a dialog.

var idealSize = { width: 200, height: 500 }
{ width, height} = await PhotoshopCore.calculateDialogSize(idealSize)
CopyCopied to your clipboard
1var idealSize = { width: 200, height: 500 }
2{ width, height} = await PhotoshopCore.calculateDialogSize(idealSize)

Parameters#

convertColor#

ColorDescriptor

Converts the given color (in descriptor form) to the given color space, returning the color descriptor.

This is an internal API that is used for SolidColor and all the other color classes.

Currently, this API uses the application color settings for conversion (Edit > Color Settings...). ' In the future, we will provide color conversion based on embedded color profiles.

Parameters#

endModalToolState#

Promise<void>

End the current modal tool editing state.

// close the modal dialog, cancelling changes
await PhotoshopCore.endModalToolState(false)
CopyCopied to your clipboard
1// close the modal dialog, cancelling changes
2await PhotoshopCore.endModalToolState(false)

Parameters#

executeAsModal#

Promise<void>

ExecuteAsModal is needed when a plugin wants to make modifications to the Photoshop state. This includes scenarios where the plugin wants to create or modify documents, or the plugin wants to update UI or preference state.

ExecuteAsModal is only available to plugin that is using apiVersion 2 or higher.

See Modal Execution for details

Parameters#

getActiveTool#

Promise<{ classID: string ; isModal: boolean ; key: string ; title: string }>

Returns information about the active Photoshop tool.

{ title } = await PhotoshopCore.getActiveTool()
CopyCopied to your clipboard
{ title } = await PhotoshopCore.getActiveTool()

getCPUInfo#

CPUInfo

Returns information about the host CPU.

{ logicalCores, frequencyMhz, vendor } = PhotoshopCore.getCPUInfo()
var isAMD = vendor === "AMD"
var isARM = vendor === "ARM"
CopyCopied to your clipboard
1{ logicalCores, frequencyMhz, vendor } = PhotoshopCore.getCPUInfo()
2var isAMD = vendor === "AMD"
3var isARM = vendor === "ARM"

getGPUInfo#

GPUInfo

Returns OpenGL and OpenCL information about the available graphics processor.

{ gpuInfoList, clgpuInfoList } = PhotoshopCore.getGPUInfo()
console.log(JSON.stringify(gpuInfoList))
// > [{"version":"2.1 ATI-4.5.14","memoryMB":8192,"name":"16915464", ...}]
console.log(JSON.stringify(clgpuInfoList))
// > [{"version":"OpenCL 1.2 ","memoryMB":8589,"name":"AMD Radeon Pro 580X Compute Engine", ...}]
CopyCopied to your clipboard
1{ gpuInfoList, clgpuInfoList } = PhotoshopCore.getGPUInfo()
2console.log(JSON.stringify(gpuInfoList))
3// > [{"version":"2.1 ATI-4.5.14","memoryMB":8192,"name":"16915464", ...}]
4console.log(JSON.stringify(clgpuInfoList))
5// > [{"version":"OpenCL 1.2 ","memoryMB":8589,"name":"AMD Radeon Pro 580X Compute Engine", ...}]

getMenuCommandState#

Promise<boolean>

Returns whether a command menu item is available for invoking.

// can a Fill be performed?
var canFill = await PhotoshopCore.getMenuCommandState({ commandID: 1042 })
CopyCopied to your clipboard
1// can a Fill be performed?
2var canFill = await PhotoshopCore.getMenuCommandState({ commandID: 1042 })

Parameters#

getMenuCommandTitle#

Promise<string>

Returns the localized menu title of the menu command item.

var renameLayerStr = await PhotoshopCore.getMenuCommandTitle({ commandID: 2983 })
CopyCopied to your clipboard
var renameLayerStr = await PhotoshopCore.getMenuCommandTitle({ commandID: 2983 })

Parameters#

getPluginInfo#

Promise<ActionDescriptor>

Return information about the execution of the plugin. This method is intended for developing plugins. Shipping code should not use this method.

The returned information include the following properties:

numberOfPendingMainThreadTasks: Number of pending promises.

batchPlayCount: Number of batchPlay calls since the plugin was loaded.

mainThreadTimeOutCount: Number of JavaScript calls that have timed out. This is typically caused by executing commands while Photoshop is modal without using executeAsModal.

v8HeapSize: V8 heap allocated for the plugin. This number is only accurate when loading plugins through the UXP Developer Tool.

await PhotoshopCore.getPluginInfo()
CopyCopied to your clipboard
await PhotoshopCore.getPluginInfo()

isModal#

boolean

Returns true if the plugin is currently in a modal state using executeAsModal

performMenuCommand#

Promise<boolean>

Invokes the menu command via its commandID. Returns false on failure, or if the command is not available.

// select all
await PhotoshopCore.performMenuCommand({ commandID: 1017 })
CopyCopied to your clipboard
1// select all
2await PhotoshopCore.performMenuCommand({ commandID: 1017 })

Parameters#

setExecutionMode#

Promise<void>

The execution mode can be used while debugging a plugin. It is only available when the developer mode is enabled.

The following example illustrate how to enable stacktraces for batchPlay commands that fail. When stacktraces are enabled, then an error result descriptor from a batchPlay request will include a stacktrace property. The property can be used when reporting bugs to Adobe.

await PhotoshopCore.setExecutionMode({ enableErrorStacktraces: true })
CopyCopied to your clipboard
await PhotoshopCore.setExecutionMode({ enableErrorStacktraces: true })

The following illustrates how to enable console warnings when a promise is rejected:

await PhotoshopCore.setExecutionMode({ logRejections: true })
CopyCopied to your clipboard
await PhotoshopCore.setExecutionMode({ logRejections: true })

Parameters#

setUserIdleTime#

Promise<void>

Specifies the number of seconds a user must be idle on Photoshop before invoking the userIdle event handler defined with addNotificationListener. An idleTime of 0 turns off idle notifications.

await PhotoshopCore.setUserIdleTIme(3)
CopyCopied to your clipboard
await PhotoshopCore.setUserIdleTIme(3)

Parameters#

showAlert#

Promise<void>

Show a generic alert box to the user. 'OK' to dismiss.

// script has completed.
