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.
An SVGZ file is a Scalable Vector Graphics (.SVG) file compressed with gzip compression. It contains graphics data in an XML format and supports graphical elements including transparency, gradients, animations, and filters.
