TRasterImage.LoadFromRawImage procedure
Loads image data from the specified TRawImage instance.
Declaration
procedure LoadFromRawImage(const AIMage: TRawImage; ADataOwner: Boolean)Arguments
AIMage | Raw image instance loaded in the method. |
ADataOwner | True if the image owns the raw image data. |
Description
LoadFromRawImage is a procedure used to load raw image data in
AImage into the class instance.
LoadFromRawImage calls BeginUpdate to increment the update process
count, and calls EndUpdate when the image data has been loaded in
the method.
LoadFromRawImage calls Clear to free the internal save stream for
the class instance, and calls SetSize to reflect an empty image.
No additional actions are performed in the method If AImage contains an empty
image.
The Image Descriptor in AImage is assigned to the internal
TRawImage instance to capture the image metadata.
ADataOwner indicates if the internal TRawImage instance is the
owner for the image data in AImage. When set to
True, values in AImage
data are assigned directly to the pointer to the internal raw image data.
Values include the size and content for the image data, the image mask, and
the palette. When set to
False, storage for values is allocated using
GetMem and copied from AImage using the
Move routine.
