Copy in the entire region access area from a source region access.
Namespace: MediaCy.IQL.Engine
Assembly: MediaCy.IQL.Engine (in MediaCy.IQL.Engine.dll) Version: 10.0.6912.0
SyntaxVB
Sub CopyInEntireArea ( SourceRegionAccess As McRegionAccess )
Parameters
- SourceRegionAccess
- Type: MediaCy.IQL.EngineMcRegionAccess
IMcRegionAccess* : The source region access. This must have the same bounds as the current region access and also be of a "compatible" image type.
RemarksThis routine encapsulates the common task of copying the entire bounds
of one region access to another. Here, this region access is the destination,
while the argument is the source. If a RegionMask property is set, the copy is masked.
You should use this method rather than Src.GetArea followed by a Dst.PutArea,
because this method does the copy in strips, so that the full image does
not have to be in memory all at once. This is critical to avoid thrashing
for images that are larger than about one half the size of installed physical
memory.
