-class ImageManager from WNT inherits TShared from MMgt
-
- ---Purpose: This class defines image management
-
- uses
-
- Handle from Aspect,
- Window from WNT,
- SequenceOfImage from WNT,
- TypeOfImage from WNT,
- Image from WNT,
- WindowPtr from WNT
-
- is
-
- Create ( aWindow : WindowPtr from WNT )
- returns mutable ImageManager from WNT;
- ---Purpose: Creates a class instance
-
- Destroy ( me : mutable )
- is virtual;
- ---Purpose: Deletes all resources associated with the class instance.
- ---C++: alias ~
-
- SetFormat ( me : mutable; aFormat : TypeOfImage from WNT = WNT_TOI_XWD )
- is static;
- ---Purpose: Sets image format for output.
-
- Add ( me : mutable; anImage : Image from WNT )
- is static;
- ---Purpose: Adds <anImage> to manager.
-
- Image ( me : mutable; anIndex : Integer from Standard )
- returns Image from WNT is static;
- ---Purpose: returns Image stored at <anIndex>.
-
- Load ( me : mutable; aFileName : CString from Standard )
- returns Integer from Standard
- is static;
- ---Purpose: Loads image from file and returns its index in the
- -- sequence.
- -- Warning: Returns 0 if loading was failed.
-
- Save (
- me;
- aFileName : CString from Standard;
- aX, aY, aWidth, aHeight : Integer from Standard
- )
- returns Boolean from Standard
- is static;
- ---Purpose: Stories image to the file according to <myFormat>
- -- class field. Returns True on success, otherwise
- -- returns False.
-
- SaveBuffer (
- me;
- aFileName : CString from Standard;
- aX, aY, aWidth, aHeight : Integer from Standard
- )
- returns Boolean from Standard
- is static;
- ---Purpose: Stories contents of the double buffer window pixmap.
- -- See "Save" method.
-
- Draw (
- me : mutable;
- anIndex : Integer from Standard;
- Xc, Yc : Integer from Standard;
- aWidth : Integer from Standard;
- aHeight : Integer from Standard;
- anAngle : Real from Standard = 0.0
- )
- is static;
- ---Purpose: Displays the image according to the DoubleBuffer state
- -- of the associated window.
-
- Delete ( me : mutable; anIndex : Integer from Standard )
- is static;
- ---Purpose: Deletes an image at index <anIndex>.
-
- Discard ( me : mutable; anIndex : Integer from Standard )
- is static;
- ---Purpose: Places an image to the trash
-
- Scale (
- me : mutable;
- anIndex : Integer from Standard;
- aScaleX : Real from Standard;
- aScaleY : Real from Standard;
- aReplace : Boolean from Standard = Standard_False
- ) returns Handle from Aspect is static;
- ---Purpose: Scales the specified image.
-
- Size ( me ) returns Integer from Standard is static;
- ---Purpose: Returns number of loaded images.
-
- ImageHandle (
- me : mutable;
- anIndex : Integer from Standard
- ) returns Handle from Aspect is static;
- ---Purpose: Returns image handle.
-
- Dim (
- me : mutable;
- anIndex : Integer from Standard;
- aWidth, aHeight : out Integer from Standard
- )
- is static;
- ---Purpose: Returns image dimensions.
-
- HashCode (
- me : mutable;
- anIndex : Integer from Standard
- )
- returns Integer from Standard is redefined static;
- ---Purpose: Returns image's hash code.
-
- Index (
- me : mutable;
- aHashCode : Integer from Standard
- )
- returns Integer from Standard is static;
- ---Purpose: Returns image's index.
-
- StringHashCode (
- me : mutable;
- aString : CString from Standard
- )
- returns Integer from Standard is static;
- ---Purpose: Returns hash code of the string.
-
- Open (
- me : mutable;
- aDC : Handle from Aspect;
- aWidth : Integer from Standard;
- aHeight : Integer from Standard;
- aHashCode : Integer from Standard
- )
- returns Integer from Standard is static;
- ---Purpose: Creates new empty image and returns its index
