ICO to TGA converter

ICO is a graphics file format used for computer icons. It was created by Microsoft for use with Windows, and most image editors support the creation and saving of this image type. ICO files contain small images and are typically saved in either 16x16 pixel or 32x32 pixel sizes, but larger sizes are also supported.

ICO files use a specific header which contains metadata, followed by an array of bits that represent the pixels. It supports several color depths (typically 1, 4 and 8 bits per pixel) and can include optional transparency and alternative image formats. ICO files can sometimes contain multiple sizes or variations of the same icon, allowing it to be scaled to different sizes while maintaining a consistent appearance.

TGA is a raster graphics file format developed by Truevision, Inc. It is primarily used for gaming purpose. It is a popular format for storing high-dynamic range content and intermediary frames for video production. TGA files come in uncompressed and compressed form and can be 8-bit or 16-bit. It can also contain 24-bit or 32-bit RGB color values.

A TGA file is composed of one or more Image Descriptors (ID), which contain information about the format and size of the image, as well as some other useful information such as bits per pixel, palette colors, etc. The TGA file format also supports various compression techniques such as RLE and ZIP compression.
