Prerequisites

Following prerequisites are required only in React Component installation, but they're included in CDN bundle installation and added as dependencies of other bridges/adapters packages.

All of the following libraries are required, as the plugin is depending on them in the implementation.

• react, react-dom: >= v17.0.0
• react-konva >= v17.0.0
• styled-components: >= v5.3.5

Compatability table (installed version of react should meet the opposite react-konva version in the table).

npm install --save react react-dom react-konva styled-components

Installation

NPM

React component

npm install --save react-filerobot-image-editor

VanillaJS

npm install --save filerobot-image-editor react-filerobot-image-editor

NOTE: if your npm version < 7 you don't need to install react-filerobot-image-editor .

CDN

VanillaJS only

// latest => last production version of the plugin, possible to replace with some earlier version (ex. 3.17.0) & if available will be requested
<script src="https://scaleflex.cloudimg.io/v7/plugins/filerobot-image-editor/latest/filerobot-image-editor.min.js"></script>

IMPORTANT NOTE: In all installation cases you must import the font family that will be used from your side as it is not included in the library by default, the default font family used is Roboto in 2 font-weight (normal === 400 & medium === 500) which fall-backs to Arial if not found.

Just import the font in your HTML/JS file before loading the plugin whether it's Roboto or you have provided another fontFamily from theme property and that's all!

NOTE: if you are importing the library from CDN then you could access it using window.FilerobotImageEditor and access both TABS & TOOLS from window.FilerobotImageEditor.TABS & window.FilerobotImageEditor.TOOLS, see tabsIds.

Config

NOTE: The plugin respects the container/wrapper HTML element through CSS by having both width & height set 100% so you could change the width/height of the plugin through adding/changing width/height of the wrapper HTML element.

Properties

source

Type: string | HTMLImageElement Required.

Supported version: +v4.0.0

Default: undefined.

The image url or an HTMLImageElement for the image which the operations/edits will be applied on.

theme

Type: object

Supported version: +v4.0.0

Default:

Theme from @scaleflex/ui deep merged with following overrides

// Overrides
{
  palette: {
    'bg-primary-active': '#ECF3FF',
  },
  typography: {
    fontFamily: 'Roboto, Arial',
  },
}

// Used properties in case you need to provide your custom colors/theme, you should customize those properties (all or any of them) with your color hex/name string values.
{
  palette: {
    'bg-secondary': '....',
    'bg-primary': : '....',
    'bg-primary-active': : '....',
    'accent-primary': : '....',
    'accent-primary-active': : '....',
    'icons-primary': : '....',
    'icons-secondary': : '....',
    'borders-secondary': : '....',
    'borders-primary': : '....',
    'borders-strong': : '....',
    'light-shadow': : '....',
    'warning': : '....',

  },
  typography: {
    fontFamily: : '....', // Font family string value, you should import this font in your app.
  },
}

Almost you would need those 2 objects (palette values are the possible keys for palette object & typograpghy) to have the proper theme you want.

As the colors of the plugin are retrieved dynamically from the theme object, it gives you the possibility to customize the colors and font-family to yours.

NOTE: You must import the font family from your side in 2 weights (Normal === 400, Medium === 500) to have fonts work properly and show text as expected, which means Roboto is not included in the plugin by default so you must import it from your side too if you have provided another font family value through theme don't forget to import it from your side too.

savingPixelRatio

Type: number

Supported version: +v4.0.0

Default: 4

The pixel ratio used in saving the image (higher the ratio, higher the resolution of the saved image till reaching the possible max. resolution for the image, higher the memory used & processing time of saving).

previewPixelRatio

Type: number

Supported version: +v4.0.0

Default: window.devicePixelRatio

The pixel ratio used in previewing the image while doing the operations (higher the ratio, higher the resolution of the drawn/previewed image in the plugin till reaching the possible max. resolution for the image, higher the processing time of drawing the image & more memory used).

High pixel ratio might cause some device crashes/slowness while drawing/previewing and doing operations so consider choosing an appropriate ratio for your use case.

If left provided [] or left default value the arrow button that would open the menu will be hidden, otherwise it'll be shown

Option's object to be provided,

NOTE: you must provide an onSave callback function on using any of the passed functions to the option's onClick function. example,

[
  {
    label: 'Save as new version',
    onClick: (triggerSaveModal, triggerSave) =>
      triggerSaveModal((...args) => {
        console.log('saved', args);
      }), // Required to pass the callback function
    icon: '<svg width="14" height="14" viewBox="0 0 14 14" fill="none" xmlns="http://www.w3.org/2000/svg">...</svg>', // HTML Element as string
  },
  {
    label: 'Save as new file',
    onClick: (triggerSaveModal, triggerSave) =>
      triggerSave((...args) => {
        console.log('saved', args);
      }), // Required to pass the callback function
    icon: () => (
      <svg
        width="14"
        height="14"
        viewBox="0 0 14 14"
        fill="none"
        xmlns="http://www.w3.org/2000/svg"
      >
        ...
      </svg>
    ), // React Function component
  },
];

observePluginContainerSize

Type: boolean

Supported version: +v4.0.0

Default: false

By default the plugin's root HTML Element is set with 100% for both height & width to respect the plugin's container HTML element size using CSS, If provided true to this property then that root element will always be the same absolute width & height values of the plugin's container HTML Element through JS observable not CSS.

NOTE: This property might be useful in some cases (one of them if you leave height of the container element to auto or didn't set it) in those cases the root element will be the same current size values of the container by JS.

showCanvasOnly

Type: boolean

Supported version: +v4.0.0

Default: false

Hides all the UI of the plugin including (save & close buttons, tabs & tools bars...etc.) except the canvas only if true, otherwise the whole UI will be shown as normal.

This prop might be useful if are using the editor in different ways in the same project, (ex. using the editor in doing different transformations for quick photo editing & using the editor after uploading some profile photo to crop the photo only and dismiss other transformations).

getCurrentImgDataFnRef

Type: React Ref | Object

Supported version: +v4.0.0

Default: undefined

If provided the canvas processing/saving/manipulating function will be assigned as .current property to this passed Object | React Ref to be used/called somewhere else other than the default save button and returns both the final transformed image data object & current design state which are same as params as onSave callback,

The passed object/ref becomes with the following syntax after assigning internally

{
  current: (
    imageFileInfo = {},
    pixelRatio = false,
    keepLoadingSpinnerShown = false,
  ) => ({
    imageData, // An object has the current image data & info
    designState, // An object contains the current design state of the image's editor
    hideLoadingSpinner, // A function hides the loading spinner on calling if not already hidden (useful in case you have provided `keepLoadingSpinnerShown` param with `true` and wants to hide the spinner after finishing some operation from ur side)
  });
}

The function has the following params:

• imageFIleInfo: An object, defines the info of the file to be considered while saving, and contains the following properties:

  {
    name,
    extension,
    quality, // applied in JPEG/JPG/WEBP formats only
    size: { // used in resizing
      width, height
    },
  }

• pixelRatio: A number, that defines the pixel ratio used in transforming/saving the image (higher the ratio, higher the resolution of the saved image till reaching the possible max. resolution for the image, higher the memory used & processing time of saving/transforming).

NOTE: Calling the assigned function will be UI blocker so take care where & when you are calling the function.

updateStateFnRef

Type: React Ref | Object

Supported version: +v4.0.0

Default: undefined

Assigns the update state main function of the plugin inside .current property of the passed object/ref to be used in changing the main state of the application, the function has 1 paramter that could be either (function | object) the function receives the current state object as argument. The object is the new state part, in both types not required to return/pass the whole state object as it gets deep merged with the current state.

NOTE: Be-aware while using this function as it might cause an un-expected behavior and we don't recommend to use it unless you know what you are doing.

useZoomPresetsMenu

Type: Boolean

Supported version: +v4.1.0

Default: true

On clicking on the zoom percentage and having this property set true some zoom presets percentages will be shown for the user to quickly choose some zoom percentage, if set to false the zoom presets won't be shown and only fit percentage will be used as default.

Note: If disableZooming property is true then this property won't have any effect.

disableZooming

Type: Boolean

Supported version: +v4.2.0

Default: false

If true, there will be no zooming functionality available in the plugin & UI related to zooming will be removed.

Callbacks

onBeforeSave

Type: function(imageFileInfo) {}

Supported version: +v4.0.0

Default: undefined

This function will be fired once the user clicks save button and before triggering the default saving behavior...

If the function returned false then the default saving behavior implemented in the plugin won't be triggered.

This function doesn't work in (cloudimage mode & moreSaveOptions) and the onSave is fired directly.

onSave

Type: function(imageData, imageDesignState) {}

Supported version: +v4.0.0

Default: undefined

it's used for handling the save functionality which is triggered once the user clicks on save button of the saving modal or once clicking the save button if the default behavior is prevented from onBeforeSave function, If you need to keep showing the loading spinner (shown on start saving) till you finish some functionality/operation from your project's side (ex. async uploading file to your server) then you must return a Promise otherwise returning nothing/void is fine.

In imageData parameter you have 2 formats (Base64 string & Canvas HTML element) of saved image, the Canvas HTML element format doesn't support quality chosen while saving from default behavior.

onModify

Type: function(currentImageDesignState)

Supported version: +v4.0.0

Default: undefined

Called after any operation/transformation is applied on the image (ex. Add/change filter, resize the image...etc.).

• currentImageDesignState: An object contains the latest design state of the current state of the plugin.

NOTE: This callback might be triggered multiple times at changing some properties related to same operation/functionality so please make sure you have checked when it's called to understand the behavior you'll have.

onClose

Type: function(closingReason, haveNotSavedChanges) {}

Supported version: +v4.0.0

Default: undefined

Triggered once the user clicks either close/cancel button or back button, if not provided then the closing button won't shown at all.

• closingReason: A string value showcases the place/reason the plugin closed.
• haveNotSavedChanges: A boolean value, true means the user has clicked the close button before saving latest changes otherwise he closed after saving.
