Key Features and Functionalities
- Image Upload: This program allows users to upload images in various formats (e.g., JPEG, PNG) by using the file upload function. This is powered by the input type=”file” tag, which is configured to accept only image files (accept=”image/*”).
- Canvas Display: Once an image is uploaded, it is displayed on a canvas . The canvas is a powerful HTML5 element/function which enablesdynamic rendering of graphics, which is ideal for real-time image manipulation. The canvas is REAL TIME responsive, adjusting its size based on the device’s screen size, ensuring a consistent user experience across different devices.
- Real-Time Image Enhancement: The core of this tool is its ability to enhance images in real-time. Users can adjust several parameters to modify the image:
- Brightness: Adjusts the overall lightness or darkness of the image.
- Contrast: Increases or decreases the difference between the lightest and darkest parts of the image.
- Sharpness: Enhances the clarity and detail of the image.
- Scale: Allows users to zoom in or out on the image.
- Color Channels (Red, Green, Blue): Adjusts the intensity of the red, green, and blue color channels, allowing for fine-tuned color correction.
- JavaScript Image Processing: The image processing is handled by JavaScript, which dynamically updates the canvas based on the user’s input. The ctx.filter property is used to apply CSS filters to the image, enabling real-time adjustments to brightness, contrast, and color channels. The ctx.drawImage method is used to scale the image based on the user’s input.
- Download Enhanced Image: After enhancing the image, users can download the modified image by clicking the “Download Enhanced Image” button. This functionality is achieved using the canvas.toDataURL() method, which converts the canvas content into a data URL that can be downloaded as an image file.
