Member Function Documentation

convertToStandardFormat()

SDL_Surface * fcn::sdl2::ImageLoader::convertToStandardFormat ( SDL_Surface * surface )

protectedvirtual

Convert a surface to a standard internal format (internal).

Definition at line 95 of file imageloader.cpp.

Referenced by fcn::opengl::ImageLoader::load(), and load().

getSDLPixelFormat()

SDL_PixelFormat const & fcn::sdl2::ImageLoader::getSDLPixelFormat

(

)

Return the current SDL pixel format used for conversions.

Definition at line 156 of file imageloader.cpp.

load() [1/2]

Image * fcn::ImageLoader::load ( std::string const & filename )

inline

Loads an image.

The single-argument overload forwards to the two-argument overload requesting conversion to display format.

NOTE: The functions Image::getPixel and Image::putPixel are only guaranteed to work before an image has been converted to display format.

Parameters

filename

The filename of the image to load.

Definition at line 59 of file imageloader.hpp.

load() [2/2]

fcn::Image * fcn::sdl2::ImageLoader::load ( std::string const & filename, bool convertToDisplayFormat )

overridevirtual

Load an image from filename.

Implements fcn::ImageLoader.

Definition at line 36 of file imageloader.cpp.

References fcn::sdl2::Image::convertToDisplayFormat(), convertToStandardFormat(), and loadSDLSurface().

loadSDLSurface()

SDL_Surface * fcn::sdl2::ImageLoader::loadSDLSurface ( std::string const & filename )

protectedvirtual

Load an SDL_Surface from disk (internal).

Definition at line 65 of file imageloader.cpp.

Referenced by fcn::opengl::ImageLoader::load(), and load().

loadSDLTexture()

SDL_Texture * fcn::sdl2::ImageLoader::loadSDLTexture ( std::string const & filename )

protectedvirtual

Load an SDL_Texture from disk (internal).

Definition at line 80 of file imageloader.cpp.

setRenderer()

void fcn::sdl2::ImageLoader::setRenderer

(

SDL_Renderer *

renderer

)

Set the SDL renderer used when creating textures.

Definition at line 60 of file imageloader.cpp.

setSDLPixelFormat()

void fcn::sdl2::ImageLoader::setSDLPixelFormat

(

SDL_PixelFormat const &

format

)

Set the SDL pixel format used for conversions.

Definition at line 161 of file imageloader.cpp.
