Belated Cloud App Suite
Great! Let's focus on developing a **basic photo editing application** inspired by Photoshop, as a starting point. I'll provide a **detailed development plan** and some **sample code snippets** to help you get started.
---
## Phase 1: Basic Photo Editor Development Plan
### Core Features:
- Load images (JPEG, PNG)
- Display image on a canvas
- Basic editing tools:
- Draw (brush)
- Eraser
- Fill (bucket tool)
- Crop
- Layers (simple implementation)
- Save/export edited image
### Technologies:
- **Framework:** Electron + React (or plain HTML/JS)
- **Rendering:** HTML5 Canvas API
- **File Handling:** FileReader API, Node.js fs module (for Electron)
---
## Step-by-step Implementation
### 1. **Setup Project Environment**
- Initialize a new Electron app with React or plain HTML/JS
- Create a main window with a menu bar
### 2. **Create UI Components**
- Toolbar with tools (brush, eraser, fill, crop)
- Canvas for image display
- Open/Save buttons
### 3. **Image Loading & Display**
- Load image into canvas
- Support drag-and-drop or file dialog
### 4. **Implement Drawing Tools**
- Draw freehand with mouse
- Erase parts of image
- Fill areas with color
### 5. **Save & Export**
- Save the current canvas as PNG/JPEG
---
## Sample Code Snippets
### **A. Load Image into Canvas**
```html
<input type="file" accept="image/*" id="upload" />
<canvas id="canvas"></canvas>
```
```js
const upload = document.getElementById('upload');
const canvas = document.getElementById('canvas');
const ctx = canvas.getContext('2d');
upload.addEventListener('change', (e) => {
const file = e.target.files[0];
const reader = new FileReader();
reader.onload = () => {
const img = new Image();
img.src = reader.result;
img.onload = () => {
canvas.width = img.width;
canvas.height = img.height;
ctx.drawImage(img, 0, 0);
};
};
reader.readAsDataURL(file);
});
```
### **B. Basic Drawing Tool (Brush)**
```js
let drawing = false;
let currentTool = 'brush';
canvas.addEventListener('mousedown', () => { drawing = true; });
canvas.addEventListener('mouseup', () => { drawing = false; });
canvas.addEventListener('mousemove', (e) => {
if (!drawing || currentTool !== 'brush') return;
ctx.lineWidth = 5;
ctx.lineCap = 'round';
ctx.strokeStyle = '#000'; // black brush
ctx.lineTo(e.offsetX, e.offsetY);
ctx.stroke();
ctx.beginPath();
ctx.moveTo(e.offsetX, e.offsetY);
});
```
### **C. Fill Tool (Bucket Fill)**
```js
canvas.addEventListener('click', () => {
if (currentTool !== 'fill') return;
const imageData = ctx.getImageData(0, 0, canvas.width, canvas.height);
// Implement flood fill algorithm here
});
```
*Note:* Flood fill implementation is more complex; can be added with a recursive or queue-based algorithm.
### **D. Save Image**
```js
function saveCanvas() {
const dataURL = canvas.toDataURL('image/png');
const link = document.createElement('a');
link.href = dataURL;
link.download = 'edited_image.png';
link.click();
}
```
---
## Next Steps:
- Expand tools: selection, crop, layers
- Add undo/redo functionality
- Improve UI/UX
- Integrate more advanced editing features

**Would you like me to generate a complete starter project codebase, or focus on specific tools or features next?**
