Constructor & Destructor Documentation

ImageManager ( size_t capacity )

Construct a new manager

Parameters

capacity Fixed capacity

~ImageManager ( )

override

Member Function Documentation

bool contains ( const std::string & name ) const

Returns true if an image with the given name exists

Parameters

name	Name of the image

Image& create	(	const std::shared_ptr< vireo::Image > &	image,
		const std::string &	name = `"Image"`
	)

Creates a bitmap from an array in memory

Parameters

image
name	Optional name

Image& create	(	const void *	data,
		uint32	width,
		uint32	height,
		vireo::ImageFormat	imageFormat = `vireo::ImageFormat::R8G8B8A8_SRGB`,
		const std::string &	name = `"Image"`
	)

Creates a bitmap from an array in memory

Parameters

data	Pixels array
width	Width in pixels
height	Height in pixels
imageFormat	Pixel format
name	Optional name

bool destroy ( const Image & res )

inlineoverridevirtual

Releases a resource by reference, decrementing its reference counter.

Parameters

res	Resource to destroy.

Returns: true if the resource was actually freed, false if references remain.

Reimplemented from lysa::ResourcesManager< Image >::destroy()

bool destroy ( unique_id id )

overridevirtual

Releases a resource by ID, decrementing its reference counter. The slot is returned to the free list only when the counter reaches zero.

Parameters

id	Unique identifier of the resource to destroy.

Returns: true if the resource was actually freed, false if references remain.

Reimplemented from lysa::ResourcesManager< Image >::destroy()

Image& get ( const std::string & name )

Returns the image with the given name, or raise an Exception if not found

Parameters

name	Name of the image (as stored at creation)

auto getBlankCubeMap ( ) const

inline

Returns the default cubemap blank image used as a safe fallback.

auto getBlankImage ( ) const

inline

Returns the default 2D blank image used as a safe fallback.

auto getImages ( ) const

inline

Return the global GPU image array

Image& load	(	const std::string &	filepath,
		vireo::ImageFormat	imageFormat = `vireo::ImageFormat::R8G8B8A8_SRGB`
	)

Load a bitmap from a file.
Supports JPEG and PNG formats

Parameters

filepath	Source file URI
imageFormat	Image pixel format

void save	(	unique_id	image_id,
		const std::string &	filepath
	)

Save an image into a file.
Supports PNG and HDR formats.

Parameters

image_id	Image
filepath	Destination file URI
