BMP to PNG

Converting BMP to PNG involves transforming raster image data from the BMP format to the PNG format. PNG (Portable Network Graphics) is a lossless compression format suitable for images with high-quality graphics or transparent backgrounds.

Here are the steps to convert BMP to PNG:

1. Read BMP Image: Load the BMP image file from the file system or a URL into memory.

2. Decode BMP Data: Decode the BMP image data to extract pixel values and metadata such as width, height, and color depth.

3. Encode as PNG: Encode the decoded pixel data and metadata into the PNG format. This process involves compressing the image data and storing it in a PNG file structure.

4. Save PNG Image: Save the PNG-encoded image data to a new file or buffer, ready for use or further processing.

Uses of BMP to PNG Conversion:

• Lossless Compression: Convert BMP images to PNG to preserve image quality without introducing compression artifacts or loss of detail.
• Transparent Backgrounds: PNG format supports alpha transparency, making it suitable for images with transparent backgrounds or overlays.
• Web Graphics: Use PNG format for web graphics, logos, icons, and other images requiring high quality and transparency.

Example Inputs and Outputs:

1. Input BMP Image: "image1.bmp" Output PNG Image: "image1.png"

2. Input BMP Image: "photo.bmp" Output PNG Image: "photo.png"

3. Input BMP Image: "logo.bmp" Output PNG Image: "logo.png"

In these examples, the BMP images are converted to PNG format, resulting in PNG images with the same content but lossless compression and support for transparent backgrounds if needed. The converted PNG images can be used in various applications, including web development, graphic design, and digital publishing.
