Detailed Description

Base class for texture implementations that depend on the backend.

Member Function Documentation

getSize()

virtual Vector2u tgui::BackendTextureBase::getSize ( ) const

virtual

Returns the size of the entire image.

Returns

Texture size

isSmooth()

virtual bool tgui::BackendTextureBase::isSmooth ( ) const

virtual

Returns whether the smooth filter is enabled or not.

Returns

True if smoothing is enabled, false if it is disabled

isTransparentPixel()

bool tgui::BackendTextureBase::isTransparentPixel

(

Vector2u

pixel

)

const

Checks if a certain pixel is transparent.

Parameters

pixel

Coordinate of the pixel

Returns

True when the pixel is transparent, false when it is not

load()

virtual bool tgui::BackendTextureBase::load ( Vector2u  size, std::unique_ptr< std::uint8_t[]>  pixels  )

virtual

Loads the texture from an array of 32-bits RGBA pixels.

Parameters

size	Width and height of the image to create
pixels	Moved pointer to array of size.x*size.y*4 bytes with RGBA pixels, or nullptr to create an empty texture

setSmooth()

virtual void tgui::BackendTextureBase::setSmooth ( bool  smooth )

virtual

Changes whether the smooth filter is enabled or not.

Parameters

smooth

True if smoothing should be enabled, false if it should be disabled
