/** |
|
@brief TGA importer plugin |
|
|
|
Supports Truevision TGA (`*.tga`, `*.vda`, `*.icb`, `*.vst`) uncompressed BGR, |
|
BGRA or grayscale images with 8 bits per channel. |
|
|
|
This plugin is built if `WITH_TGAIMPORTER` is enabled when building Magnum. To |
|
use dynamic plugin, you need to load `TgaImporter` plugin from |
|
`MAGNUM_PLUGINS_IMPORTER_DIR`. To use static plugin or use this as a dependency |
|
of another plugin, you need to request `TgaImporter` component of `Magnum` |
|
package in CMake and link to `Magnum::TgaImporter` target. See @ref building, |
|
@ref cmake and @ref plugins for more information. |
|
|
|
The images are imported with @ref PixelType::UnsignedByte and @ref PixelFormat::RGB, |
|
@ref PixelFormat::RGBA or @ref PixelFormat::Red, respectively. Grayscale images |
|
require extension @extension{ARB,texture_rg}. Imported images are imported with |
|
default @ref PixelStorage parameters except for alignment, which may be changed |
|
to `1` if the data require it. |
|
|
|
In OpenGL ES 2.0, if @extension{EXT,texture_rg} is not supported and in |
|
WebGL 1.0, grayscale images use @ref PixelFormat::Luminance instead of |
|
@ref PixelFormat::Red. |
