Constructor & Destructor Documentation

◆ Texture() [1/2]

tgui::Texture::Texture ( const char *  id,
const UIntRect partRect = UIntRect(0, 0, 0, 0),
const UIntRect middlePart = UIntRect(0, 0, 0, 0),
bool  smooth = true 
)
inline

Constructor that created the texture.

Parameters
idId for the the image to load (for the default loader, the id is the filename)
partRectLoad only part of the image. Pass an empty rectangle if you want to load the full image
middlePartChoose the middle part of the image for 9-slice scaling (relative to the part defined by partRect)
smoothEnable smoothing on the texture

◆ Texture() [2/2]

tgui::Texture::Texture ( const String id,
const UIntRect partRect = UIntRect(0, 0, 0, 0),
const UIntRect middlePart = UIntRect(0, 0, 0, 0),
bool  smooth = true 
)

Constructor that created the texture.

Parameters
idId for the the image to load (for the default loader, the id is the filename)
partRectLoad only part of the image. Pass an empty rectangle if you want to load the full image
middlePartChoose the middle part of the image for 9-slice scaling (relative to the part defined by partRect)
smoothEnable smoothing on the texture

This constructor just calls the corresponding load function.

Member Function Documentation

◆ getBackendTextureLoader()

static const BackendTextureLoaderFunc& tgui::Texture::getBackendTextureLoader ( )
static

Returns the used backend texture loader.

Returns
Backend texture loader that is currently being used
See also
setBackendTextureLoader

◆ getColor()

const Color& tgui::Texture::getColor ( ) const

Returns the global color of the texture.

This color is modulated (multiplied) with the pixel color. It can be used to colorize the texture, or change its global opacity. Note that the alpha component is multiplied with the opacity of the widget.

By default, the texture's color is opaque white.

Returns
Current color of the texture

◆ getData()

std::shared_ptr<TextureData> tgui::Texture::getData ( ) const

Returns the texture data.

Returns
Data of the texture

◆ getId()

const String& tgui::Texture::getId ( ) const

Returns the id that was used to load the texture (for the default loader, the id is the filename)

Returns
Id of the texture

◆ getImageSize()

Vector2u tgui::Texture::getImageSize ( ) const

Returns the size that the loaded image, or the size of the part if only a part of the image is loaded.

Returns
Size of the image like it was when loaded (no scaling applied)

◆ getMiddleRect()

UIntRect tgui::Texture::getMiddleRect ( ) const

Returns the middle rect of the texture which is used for 9-slice scaling.

Returns
Middle rect of the texture

◆ getPartRect()

UIntRect tgui::Texture::getPartRect ( ) const

Returns which part of the image was loaded.

Returns
Part of the image that was loaded

◆ getTextureLoader()

static const TextureLoaderFunc& tgui::Texture::getTextureLoader ( )
static

Returns the used texture loader.

Returns
Texture loader that is currently being used
See also
setTextureLoader

◆ isSmooth()

bool tgui::Texture::isSmooth ( ) const

Tells whether the smooth filter is enabled or not.

Returns
True if smoothing is enabled, false if it is disabled

◆ isTransparentPixel()

bool tgui::Texture::isTransparentPixel ( Vector2u  pos) const

Checks if a certain pixel is transparent.

Parameters
posCoordinate of the pixel
Returns
True when the pixel is transparent, false when it is not

◆ load()

void tgui::Texture::load ( const String id,
const UIntRect partRect = {},
const UIntRect middleRect = {},
bool  smooth = true 
)

Creates the texture.

Parameters
idId for the the image to load (for the default loader, the id is the filename)
partRectLoad only part of the image. Don't pass this parameter if you want to load the full image
middleRectChoose the middle part of the image for 9-slice scaling (relative to the part defined by partRect)
smoothEnable smoothing on the texture

◆ setBackendTextureLoader()

static void tgui::Texture::setBackendTextureLoader ( const BackendTextureLoaderFunc &  func)
static

Sets a different backend texture loader.

Parameters
funcNew backend texture loader function

The backend texture loader will be called inside the texture loader to create the backend texture.

The default loader will simply load the image from a file.

◆ setColor()

void tgui::Texture::setColor ( const Color color)

Sets the global color of the texture.

This color is modulated (multiplied) with the pixel color. It can be used to colorize the texture, or change its global opacity. Note that the alpha component is multiplied with the opacity of the widget.

By default, the texture's color is opaque white.

Parameters
colorNew color of the texture

◆ setCopyCallback()

void tgui::Texture::setCopyCallback ( const CallbackFunc &  func)

Sets a callback function for when this texture is copied.

Parameters
funcFunction that will be called when this texture is copied

This function can be useful when implementing a resource manager.

◆ setDestructCallback()

void tgui::Texture::setDestructCallback ( const CallbackFunc &  func)

Sets a callback function for when this texture is destroyed.

Parameters
funcFunction that will be called when this texture is destroyed

This function can be useful when implementing a resource manager.

◆ setTextureLoader()

static void tgui::Texture::setTextureLoader ( const TextureLoaderFunc &  func)
static

Sets a different texture loader.

Parameters
funcNew texture loader function

The texture loader will initialize this Texture object.

The default loader will use an internal texture manager to prevent the same thing from being loaded twice.
