class PixMap from WNT
---Version:
---Purpose: This class defines a windows bitmap
---Keywords: Bitmap, Pixmap
inherits
PixMap from Aspect
uses
Handle from Aspect,
Color from Quantity,
Window from Aspect
raises
PixmapDefinitionError from Aspect,
PixmapError from Aspect
is
Create ( aWindow : Window from Aspect;
aWidth, anHeight : Integer from Standard;
aCDepth : Integer from Standard = 0 )
returns mutable PixMap from WNT
raises PixmapDefinitionError from Aspect;
---Level: Public
---Purpose: Warning! When <aDepth> is NULL , the pixmap is created
-- with the SAME depth than the window <aWindow>

Destroy ( me : mutable )
---Level: Advanced
---Purpose: Destroies the Bitmap
---C++: alias ~
-- Trigger: Raises if Bitmap is not defined properly
raises PixmapError from Aspect is virtual;
Dump ( me; aFilename : CString from Standard ;
aGammaValue: Real from Standard = 1.0 )
returns Boolean
---Level: Advanced
---Purpose:
-- Dumps the Bitmap to an image file with
-- an optional gamma correction value
-- and returns TRUE if the dump occurs normaly.
---Category: Methods to modify the class definition
raises PixmapError from Aspect is virtual;

---Purpose:
-- Returns the pixel color.
