FromTiff

Bake a 16-bit (or 8-bit or floating point) single-band TIFF.

Declaration

EOrreryTerrainBrushBake FromTiff(const uint8* Data, int64 Size, const FBakeSpec& Spec,
                                                        std::shared_ptr<const OrreryTerrain::Native::FBrushMask>& OutMask, FString* Why = nullptr);

Header: #include "OrreryTerrainBrushAsset.h"
Module: PublicDependencyModuleNames.Add("OrreryTerrain"); in your module’s Build.cs.
Stability: Stable: changes within a major version only add.
Thread: Any thread.

Description

The samples are read as the DEM importer reads heights, then normalised to the file's own range: its lowest valid sample becomes black and its highest white, so a DEM snippet becomes a mountain whose Stamp Strength is its peak. A file with no valid sample, or a flat one, bakes to black. Samples without data are black.

Parameters

Name	Type	Default	Meaning
`Data`	`const uint8*`	—	The whole file.
`Size`	`int64`	—	Bytes in the file.
`Spec`	`const FBakeSpec&`	—	The bake settings; the channel is ignored.
`OutMask`	`std::shared_ptr<const OrreryTerrain::Native::FBrushMask>&`	—	The mask on Ok.
`Why`	`FString*`	`nullptr`	Optional; on BadTiff the reader's message.

Returns

Ok, BadTiff, BadSize or Refused.

Note.
