Magnum::Trade::TgaImporter class

TGA importer plugin.

Supports Truevision TGA (*.tga, *.vda, *.icb, *.vst) uncompressed BGR, BGRA or grayscale images with 8 bits per channel.

This plugin depends on the Trade library and is built if WITH_TGAIMPORTER is enabled when building Magnum. To use as a dynamic plugin, you need to load the "TgaImporter" plugin from MAGNUM_PLUGINS_IMPORTER_DIR. To use as a static plugin or use this as a dependency of another plugin with CMake, you need to request the TgaImporter component of the Magnum package and link to the Magnum::TgaImporter target. See Downloading and building, Usage with CMake and Loading and using plugins for more information.

The images are imported with PixelType::UnsignedByte and PixelFormat::RGB, PixelFormat::RGBA or PixelFormat::Red, respectively. Grayscale images require extension ARB_texture_rg. Imported images are imported with default PixelStorage parameters except for alignment, which may be changed to 1 if the data require it.

In OpenGL ES 2.0, if EXT_texture_rg is not supported and in WebGL 1.0, grayscale images use PixelFormat::Luminance instead of PixelFormat::Red.
