Usage: you must use this class as is. You should never derive it.
public class CAT2DImagePixelRep
Class to create a representation of a 2D image.
Role:
This representation allows to constructs an image with pixels
in 2D.
Constructor and Destructor Index
- o
CAT2DImagePixelRep(float[2],CATPixelImage*,int,int,int,int)
- Constructs a 2D image representation.
- o
~CAT2DImagePixelRep()
-
Method Index
- o
GetPixelImage()
- Returns the 2D pixel image associated with the representation.
- o
Modify(float[2])
- Modifies the position of the 2D image representation.
- o
SetAlphaMode(int)
- Sets the alpha mode.
Constructor and Destructor
o CAT2DImagePixelRep
| public CAT2DImagePixelRep( | const | iPoint, |
| const | iPixelImage, |
| | iZoomQuality | = 0, |
| | iXPixelOffset | = 0, |
| | iYPixelOffset | = 0, |
| | iScaleOffset | = 0) |
-
Constructs a 2D image representation.
- Parameters:
-
- iPoint
- the position of the graphic primitive in a 2D space (in model coordinates).
- iPixelImage
- the 2D image used to create the 2D graphic primitive.
- iZoomQuality
- the zoom quality.
legal values:
- 0 : no zoom available.
- 1 : low quality zoom.
- 2 : high quality zoom (smooth).
The default value is 0 (no zoom).
- iXPixelOffset
- The offset along X axis. It allows to translate the graphic primitive from
the iPoint. iXPixelOffset is expressed in pixels.
legal values:
the default value is 0 (no translation along X axis)
- iYPixelOffset
- The offset along Y axis. It allows to translate the graphic primitive from
the iPoint. iYPixelOffset is expressed in pixels.
legal values:
the default value is 0 (no translation along Y axis)
- iScaleOffset
- Do not use.
o ~CAT2DImagePixelRep
| public virtual ~CAT2DImagePixelRep( | ) |
-
Methods
o GetPixelImage
-
Returns the 2D pixel image associated with the representation.
o Modify
| public Modify( | const | oPoint) |
-
Modifies the position of the 2D image representation.
- Parameters:
-
- oPoint
- the position of the 2D image representation.
o SetAlphaMode
| public SetAlphaMode( | | iOnOff) |
-
Sets the alpha mode.
Alpha mode allows to define a degree of transparency for each pixel of the
2D image representation.
- Parameters:
-
- iOnOff
- the integer which defines the alpha mode.
legal values:
- 0 : alpha mode is not activated
- 1 : alpha mode is activated and transparency is managed as a mask:
if alpha is inferior to 128 the color is fylly transparent, if it is superior the color is fully opaque.
- 2 : alpha mode is activated and transparency is managed as true transparency
