Resizing images is a common task in image processing, and Java provides several libraries and methods to accomplish this.

Solution Using imgscalr

imgscalr is a popular open-source Java library specifically designed for image scaling. It offers a user-friendly interface and multiple optimization algorithms to choose from.

<code class="java">BufferedImage scaledImage = Scalr.resize(myImage, 200);</code>

This line resizes the image myImage within a bounding box of 200 pixels wide and 200 pixels tall, maintaining its original aspect ratio. imgscalr automatically selects the best optimization algorithm based on the input parameters.

Additional Features of imgscalr

• Resize to specific width or height, preserving aspect ratio
• Scale proportionally
• Crop or pad images
• Rotate and flip images
• Apply various filters (e.g., sharpen, blur)
