Public Attributes
std::unordered_map< RDevice *, CZBitset< RImageCap > >	caps
	Required caps for each device. Leave empty to disable constraints.
std::unordered_set< RFormat >	readFormats
	Required read formats (the image must support at least one). Leave empty to disable constraints.
std::unordered_set< RFormat >	writeFormats
	Required write formats (the image must support at least one). Leave empty to disable constraints.
RDevice *	allocator { nullptr }
	The allocator device; if nullptr, RCore::mainDevice() is used.

Detailed Description

Constraints applied when allocating an RImage.

Used by the RImage factory functions to require specific capabilities and formats.

caps

std::unordered_map<RDevice*, CZBitset<RImageCap> > caps

Required caps for each device. Leave empty to disable constraints.
