	)

static

Load an image from a memory buffer.

static ByteArray* omega::ImageUtils::encode	(	PixelData *	data,
		ImageFormat	format
	)

static

Encodes an image using the specified format. Returns a byte array containing the encoded image data.

static

static Ref<PixelData> omega::ImageUtils::loadImage	(	const String &	filename,
		bool	hasFullPath = `false`
	)

static

Load an image from a file.

static LoadImageAsyncTask* omega::ImageUtils::loadImageAsync	(	const String &	filename,
		bool	hasFullPath = `false`
	)

static

Load image from a file (async)

static Ref<PixelData> omega::ImageUtils::loadImageFromStream	(	std::istream &	fin,
		const String &	streamName
	)

static

Load an image from a stream.

static void omega::ImageUtils::loadImagesAsync ( const std::list< Ref< LoadImageAsyncTask > > & tasks )

static

static bool omega::ImageUtils::preallocateBlocks	(	size_t	size,
		int	numBlocks
	)

static

Preallocated memory management.

Preallocate memory blocks for image loading and processing.

Returns: true if preallocation succeeded. False otherwise.

static bool omega::ImageUtils::saveImage	(	const String &	filename,
		PixelData *	data,
		ImageFormat	format
	)

static

Save PixelData to a file with format.

static void omega::ImageUtils::setImageLoaderThreads ( int num )

inlinestatic

Sets the number if image loading threads. Must be called before the fist call to loadImageAsync.

static void omega::ImageUtils::setLoadPreallocatedBlock ( int blockId )

static

Specified which preallocated block to use when loading images.

Pass -1 to disable preallocated block usage on image loading.

static void omega::ImageUtils::setVerbose ( bool value )
