/** |
|
@brief TGA importer plugin |
|
|
|
Supports 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_LIBRARIES}`. See |
|
@ref building, @ref cmake and @ref plugins for more information. |
|
|
|
The images are imported with @ref ColorType::UnsignedByte and @ref ColorFormat::BGR, |
|
@ref ColorFormat::BGRA or @ref ColorFormat::Red, respectively. Grayscale images |
|
require extension @extension{ARB,texture_rg}. |
|
|
|
In OpenGL ES BGR and BGRA images are converted to @ref ColorFormat::RGB |
|
and @ref ColorFormat::RGBA. In OpenGL ES 2.0, if @es_extension{EXT,texture_rg} |
|
is not supported, grayscale images use @ref ColorFormat::Luminance instead of |
|
@ref ColorFormat::Red. |
