Installation

npm install @rageshpikalmunde/rp-image-editor

Quick Start

Vanilla JavaScript / TypeScript

import { openEditorModal } from '@rageshpikalmunde/rp-image-editor';

const fileInput = document.querySelector<HTMLInputElement>('#fileInput');

fileInput.addEventListener('change', async (e) => {
  const file = (e.target as HTMLInputElement).files?.[0];
  if (!file) return;

  const result = await openEditorModal({
    image: file,
    config: {
      exportFormat: 'jpeg',
      exportQuality: 0.92,
      theme: {
        headerTitle: 'Edit Photo',
        applyButtonBackground: '#4a90d9',
      },
    },
  });

  if (result) {
    console.log(result.file);   // File object — upload via FormData
    console.log(result.base64); // data:image/jpeg;base64,...
    console.log(result.blob);   // Blob
  }
});

Angular / Ionic

import { openEditorModal } from '@rageshpikalmunde/rp-image-editor';

// Or use the ImageEditorService wrapper for centralized config:
// import { ImageEditorService } from './services/image-editor.service';

async onFileSelected(file: File) {
  const result = await openEditorModal({
    image: file,
    config: { exportFormat: 'jpeg', exportQuality: 0.92 },
  });

  if (result) {
    // Upload result.file to your backend
  }
}

React

import { openEditorModal } from '@rageshpikalmunde/rp-image-editor';

function ImageUploader() {
  const handleFile = async (e: React.ChangeEvent<HTMLInputElement>) => {
    const file = e.target.files?.[0];
    if (!file) return;

    const result = await openEditorModal({
      image: file,
      config: { exportFormat: 'jpeg' },
    });

    if (result) {
      // Use result.file, result.base64, or result.blob
    }
  };

  return <input type="file" accept="image/*" onChange={handleFile} />;
}

Programmatic API (Advanced)

import { RpImageEditor } from '@rageshpikalmunde/rp-image-editor';

const container = document.getElementById('editor-container');
const editor = new RpImageEditor(container, {
  exportFormat: 'png',
  maxUndoSteps: 30,
  defaultBrushColor: '#ff0000',
  showToolbar: true,
});

await editor.loadImage(file);

// Control the editor programmatically
editor.setMode('draw');
editor.zoomIn();
editor.rotate(90);

// Export
const result = await editor.getResult();
console.log(result.file);

// Clean up
editor.destroy();

Configuration

interface RpEditorConfig {
  maxResolution?: number | null;    // Max image resolution (auto-detect per platform)
  cropAspectRatios?: CropAspectRatio[];
  exportFormat?: 'png' | 'jpeg';   // Default: 'jpeg'
  exportQuality?: number;          // 0.0–1.0, Default: 0.92
  exportPixelRatio?: number;       // 1 = standard, 2 = retina. Default: 1
  maxUndoSteps?: number;           // Default: 20
  defaultBrushColor?: string;      // Default: '#ff0000'
  defaultBrushWidth?: number;      // Default: 3
  defaultTextColor?: string;       // Default: '#ff0000'
  defaultTextFontSize?: number;    // Default: 24
  colorPalette?: string[];
  showToolbar?: boolean;           // Default: true
  disabledFeatures?: string[];     // Default: [] — see below
  theme?: RpEditorTheme;
  locale?: string;
}

Disabling Features

Hide individual tools or entire groups from the toolbar:

const result = await openEditorModal({
  image: file,
  config: {
    // Hide individual tools
    disabledFeatures: ['eraser', 'reset'],

    // Or hide entire groups
    // disabledFeatures: ['zoom', 'transform'],
  },
});

Individual tool names: move, crop, zoomIn, zoomOut, rotateLeft, rotateRight, draw, text, callout, eraser, undo, redo, reset

Group names (disables all children): zoom (zoomIn + zoomOut), transform (rotateLeft + rotateRight), annotate (draw + text + callout + eraser)

Toolbar Layout

The toolbar is organized into 8 compact items with flyout menus:

| Button | Type | Contains | |---|---|---| | Move | Standalone | Pan / drag mode | | Crop | Standalone | Free & aspect-ratio crop | | Zoom ▾ | Flyout | Zoom In, Zoom Out | | Transform ▾ | Flyout | Rotate Left, Rotate Right | | Annotate ▾ | Flyout | Draw, Text, Callout, Eraser | | Undo | Standalone | Undo last action | | Redo | Standalone | Redo last undone action | | Reset | Standalone | Reset to original image |

const result = await openEditorModal({
  image: file,
  config: {
    theme: {
      headerBackground: '#1a1a2e',
      headerTextColor: '#ffffff',
