Reader Overview

FME considers a single TARGA file to be a dataset.

The TARGA file contains pixel data, and each pixel in the file is a point in a single FME raster feature.

The reader supports reading 1-band (Monochrome), 2-band (Monochrome with Alpha), 3-band (RGB), and 4-band (RGBA) TARGA images as per the TGA 2.0 standard.

FME Raster Features

FME raster features represent raster data and use several concepts that are unlike those used in the handling of vector data. The topics below describe how FME processes raster data.

TARGA files can be written with non-square pixel dimensions. TARGA supports rasters with a Red8, a Green8, and a Blue8 band, or a single Grey8 band (and optional alpha). (FME also supports 16-bit versions, although they are not explicitly mentioned in the TGA 2.0 standard.)

TARGA also supports rasters with a single UInt8 or UInt16 band that has an RGB24 or RGBA32 palette.
