How Can I Resize an Image in C# Without Significant Quality Loss?

Maintaining Image Quality During Resizing in C#

Resizing images without noticeable quality degradation is a frequent challenge. While completely eliminating quality loss is impossible, smart techniques can significantly minimize it.

Optimal C# Resizing Method

The following C# code provides a high-quality resizing solution:

Bitmap newImage = new Bitmap(newWidth, newHeight);
using (Graphics gr = Graphics.FromImage(newImage))
{
    // Optimize for quality
    gr.SmoothingMode = SmoothingMode.HighQuality;
    gr.InterpolationMode = InterpolationMode.HighQualityBicubic;
    gr.PixelOffsetMode = PixelOffsetMode.HighQuality;

    // Resize the image
    gr.DrawImage(srcImage, new Rectangle(0, 0, newWidth, newHeight));
}

This code uses superior settings for smoothing, interpolation, and pixel offset, resulting in a resized image with minimal quality compromise, retaining sharpness and detail.
