MioMap & IGO BMP: Understanding the File Format and Compression

What is MioMap & IGO BMP?

MioMap & IGO BMP is a file format used by MioMap and IGO navigation systems to store map images. The format is a compressed version of the BMP (Bitmap) image file, which is a widely used raster image file format. The compression algorithm used by MioMap & IGO BMP is designed to reduce the file size of the map images while maintaining their quality.

Understanding the Compression Format

The compression format used by MioMap & IGO BMP is a lossy compression algorithm, which means that it discards some of the data in the image to reduce its size. This results in a smaller file size, but it also means that the image quality may be affected. The compression algorithm used by MioMap & IGO BMP is designed to reduce the number of colors in the image, which is achieved by reducing the number of unique colors in the image.

Key Features of MioMap & IGO BMP

  • Maximum of 253 colors: The compression format used by MioMap & IGO BMP imposes a maximum of 253 colors in order to compress the image. This means that any image with more than 253 unique colors will be reduced to 253 colors or less during the compression process.
  • Transparency levels: A pixel of one color with a different level transparency will be considered as two different colors in compressed mode. This means that the compression algorithm will treat a pixel with a different transparency level as a separate color, even if it has the same color value.
  • Compressed file size: The compression algorithm used by MioMap & IGO BMP is designed to reduce the file size of the map images. The compressed file size is typically much smaller than the original BMP file size.

How to Compress and Uncompress MioMap & IGO BMP

Compressing and uncompressing MioMap & IGO BMP files can be done using various software tools. Here are the steps to compress and uncompress MioMap & IGO BMP files:

Compressing MioMap & IGO BMP

To compress a MioMap & IGO BMP file, you can use the following steps:

  1. Open the file: Open the MioMap & IGO BMP file using a software tool that supports the format.
  2. Select the compression option: Select the compression option from the software tool's menu.
  3. Choose the compression level: Choose the compression level that you want to use. The higher the compression level, the smaller the file size will be, but the image quality may be affected.
  4. Save the compressed file: Save the compressed file with a new file name.

Uncompressing MioMap & IGO BMP

To uncompress a MioMap & IGO BMP file, you can use the following steps:

  1. Open the file: Open the MioMap & IGO BMP file using a software tool that supports the format.
  2. Select the uncompression option: Select the uncompression option from the software tool's menu.
  3. Choose the uncompression level: Choose the uncompression level that you want to use. The higher the uncompression level, the larger the file size will be, but the image quality may be improved.
  4. Save the uncompressed file: Save the uncompressed file with a new file name.

Software Tools for Compressing and Uncompressing MioMap & IGO BMP

There are various software tools available that can compress and uncompress MioMap & IGO BMP files. Some of the popular software tools include:

  • IrfanView: A free image viewer and editor that supports the MioMap & IGO BMP format.
  • XnView: A free image viewer and editor that supports the MioMap & IGO BMP format.
