TN3 File – What is .tn3 file and how to open it?
TN3 File Extension
Tiny High-resolution Image – file format by Atari
TN3 is a file extension for a Tiny High-resolution Image format developed by Atari. It is a bitmap image format that supports high resolutions and a limited color palette.
Definition and Origins
A TN3 file is a raster image format developed by Atari for use on their Atari ST line of personal computers. TN3 files store bitmap images with a resolution of 320 x 200 pixels and a color depth of 3 bits per pixel, allowing for a maximum of 8 colors. The format was primarily used for storing low-resolution graphics for video games and user interfaces. TN3 files typically have a small file size, making them suitable for use in applications where storage space was limited.
Technical Details
TN3 files use a simple file structure, consisting of a header followed by the image data. The header contains information such as the image width, height, and color depth. The image data is stored in a packed format, with each pixel represented by a single bit. The TN3 format also supports transparency, allowing for the creation of images with transparent areas. Additionally, TN3 files can be interlaced, which can reduce the perceived flicker when the image is displayed.
TN3 File Format
TN3 is a raster graphics format specifically designed for Atari ST computers. Developed by Atari, it utilizes a simple color palette and resolution to create small, high-resolution images. TN3 files are characterized by their compact size, making them suitable for use in resource-constrained environments.
Opening TN3 Files
Opening TN3 files requires software that supports the format. Several applications can open and view TN3 images, including:
- Atari ST Emulators: Emulators such as Hatari and Steem can emulate the Atari ST platform, allowing you to open and view TN3 files within the emulated environment.
- Image Editing Software: Some image editing programs, such as GIMP and Paint.NET, provide support for opening and converting TN3 files into other image formats, making them more accessible for general use.
Atari’s TN3 File Format
The Atari TN3 file format, developed by Atari, is designed for storing Tiny High-resolution Images. TN3 files are bitmap images with a resolution of 160×100 pixels and a color depth of 16 bits. They are commonly used in Atari ST computers and games. TN3 files are compressed using a proprietary algorithm, which reduces their file size without significantly compromising image quality.
Advantages of TN3 Files
One of the primary advantages of TN3 files is their compact size, which makes them suitable for storage and transmission in environments with limited bandwidth. Additionally, the lossless compression algorithm employed by TN3 preserves the original image quality, ensuring that the decompressed image is identical to the original. TN3 files also support transparency, which allows for easy integration with other graphical elements and backgrounds.
