Public Functions#

	Name
	CompressionInfo_t() Creates and initializes a compression info struct.

	Name
bool	hasCompressedImage True if grab buffer/result provided contains a compressed image (otherwise false if buffer/result is already decompressed).
ECompressionStatus	compressionStatus Status of compression (see ECompressionStatus).
bool	lossy True if image was compressed lossily (otherwise false if it was compressed losslessly).
EPixelType	pixelType Pixel type of compressed image.
size_t	width Width (in pixels) of compressed image.
size_t	height Height (in pixels) of compressed image.
size_t	offsetX X offset (in pixels) of compressed image.
size_t	offsetY Y offset (in pixels) of compressed image.
size_t	paddingX X padding (line padding; in bytes) of compressed image.
size_t	paddingY Y padding (image padding; in bytes) of compressed image.
size_t	decompressedImageSize Size (in bytes) required for decompressed image (only valid if hasCompressedImage is true).
size_t	decompressedPayloadSize Size (in bytes; including chunk data) required for decompressed payload (only valid if hasCompressedImage is true).

struct Pylon::CompressionInfo_t;
