Detailed Description

Texture is a wrapper for SDL and OpenGL texture loading, management, and activation. It abstracts differences between SDL and OpenGL renderers for texture creation and usage.

Member Function Documentation

GetHeight()

int Texture::GetHeight

(

)

const

Gets the texture height.

Returns

Height in pixels.

GetSDLTexture()

SDL_Texture * Texture::GetSDLTexture

(

)

const

Gets the internal SDL texture pointer (only valid for SDL renderer).

Returns

Pointer to SDL_Texture.

GetWidth()

int Texture::GetWidth

(

)

const

Gets the texture width.

Returns

Width in pixels.

Load()

bool Texture::Load	(	IRenderer &	pRenderer,
		const std::string &	pFileName )

Loads a texture file using the appropriate renderer (SDL or OpenGL).

Parameters

pRenderer	Reference to the renderer (determines backend).
pFileName	Path to the texture image file.

Returns

True if the texture was successfully loaded, false otherwise.

SetActive()

void Texture::SetActive

(

int

slot

)

const

Binds the texture as the currently active OpenGL texture. Note: This only applies to OpenGL renderers.

SetTextureSize()

void Texture::SetTextureSize	(	int	width,
		int	height )

Manually sets the size of the texture.

Parameters

width	New width.
height	New height.

Unload()

void Texture::Unload

(

)

Frees resources associated with the texture.

UpdateInfo()

void Texture::UpdateInfo	(	int &	pWidthOut,
		int &	pHeightOut )

Outputs the texture dimensions to the given references.

Parameters

pWidthOut	Receives texture width.
pHeightOut	Receives texture height.
