constructor Create(const AParentNode: TX3DFileItem; const AExposed: boolean; const AName: string; const AValue: TCastleImage); |
Parameters
- AValue
- is the initial value for Value.
Note - our constructor COPIES passed reference AValue, not it's contents (I mean, we do Value := AValue, NOT Value := ImageCopy(AValue), so don't Free image given to us (at least, don't do this without clearing our Value field)). You can pass AValue = nil, then Value will be initialized to null image TRGBImage.Create.

Properties
|
property Value: TCastleImage read FValue write SetValue; |
|
Current image, expressed as the TCastleImage instance.
The image instance is by default owned by this object, which means that we will free it in destructor or when setting another value.
Value may be IsEmpty, and then we know that there is no image recorded in this field. Value may never be Nil.
