WebP is an image format employing both lossy and losslesscompression. It is currently developed by Google, based on technology acquired with the purchase of On2 Technologies. As a derivative of the VP8 video format, it is a sister project to the WebM multimedia container format. WebP-related software is released under a BSD license. The format was first announced in 2010 as a new open standard for lossily compressed true-color graphics on the web, producing smaller files of comparable image quality to the older JPEG scheme.
Truevision TGA, often referred to as TARGA, is a raster graphics file format created by Truevision Inc. (now part of Avid Technology). It was the native format of TARGA and VISTA boards, which were the first graphic cards for IBM-compatible PCs to support Highcolor/truecolor display. This family of graphic cards was intended for professional computer image synthesis and video editing with PCs; for this reason, usual resolutions of TGA image files match those of the NTSC and PAL video formats. TARGA is an acronym for Truevision Advanced Raster Graphics Adapter;TGA is an initialism for Truevision Graphics Adapter.
