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
pixelCoordinate 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
sizeWidth and height of the image to create
pixelsMoved 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
smoothTrue if smoothing should be enabled, false if it should be disabled
