Member Function Documentation

◆ allocate()

void OpenGL::FakeTexture::allocate ( uint  width,
uint  height 
)
overridevirtual

Allocate storage for surface.

Parameters
widthThe desired logical width.
heightThe desired logical height.

Reimplemented from OpenGL::Texture.

◆ setMask()

void OpenGL::FakeTexture::setMask ( const byte *  mask)
overridevirtual

Assign a mask to the surface, where a byte value of 0 is black with 0 alpha and 1 is the normal color.

Parameters
maskThe mask data.

Reimplemented from OpenGL::Surface.

◆ getFormat()

Graphics::PixelFormat OpenGL::FakeTexture::getFormat ( ) const
inlineoverridevirtual
Returns
The logical format of the texture data.

Reimplemented from OpenGL::Texture.

◆ hasPalette()

bool OpenGL::FakeTexture::hasPalette ( ) const
inlineoverridevirtual
Returns
Whether the surface is having a palette.

Reimplemented from OpenGL::Surface.

◆ setColorKey()

void OpenGL::FakeTexture::setColorKey ( uint  colorKey)
overridevirtual

Set color key for paletted textures.

This needs to be called after any palette update affecting the color key. Calling this multiple times will result in multiple color indices to be treated as color keys.

Reimplemented from OpenGL::Surface.

◆ updateGLTexture()

void OpenGL::FakeTexture::updateGLTexture ( )
overridevirtual

Update underlying OpenGL texture to reflect current state.

Reimplemented from OpenGL::Texture.

Reimplemented in OpenGL::TextureRGBA8888Swap, and OpenGL::TextureRGB555.
