Example 1: Copying an image

The following code is used to copy the content of an Image control (IMG_SourceImage) into a second Image control (IMG_DestinationImage). The user selects the copy mode via a List Box control (LIST_ListMode).

// Declare the variables
ResCopy is boolean
CopyMode is int

// Retrieve the copy mode
SWITCH LIST_ListMode
CASE 1: CopyMode = copyBlackness
CASE 2: CopyMode = copyDstInvert
CASE 3: CopyMode = copyMergeCopy
CASE 4: CopyMode = copyNotSrcCopy
CASE 5: CopyMode = copyNotSrcErase
CASE 6: CopyMode = copySrcAnd
CASE 7: CopyMode = copySrcCopy
CASE 8: CopyMode = copySrcErase
CASE 9: CopyMode = copySrcInvert
CASE 10: CopyMode = copySrcPaint
CASE 11: CopyMode = copyWhiteness
CASE 12: CopyMode = copyMergePaint
CASE 13: CopyMode = copyPatCopy
CASE 14: CopyMode = copyPatInvert
CASE 15: CopyMode = copyPatPaint
END

// Copy the content of the Image control
ResCopy = dCopyImage(IMG_SourceImage, IMG_DestinationImage, CopyMode)

// Error?
IF ResCopy = True THEN
Info("The copy was performed")
ELSE
Info("The copy was not performed")
END

Example 2: Zoom on an image

The following code is used to reduce by 50% an image displayed in an Image control (IMG_SourceImage) whose coordinates are (0,0), (150,200). The reduced-size image is copied into a second Image control (IMG_DestinationImage).

// Declare the variables
ResCopy is boolean

// Reduce the size of the selected image
ResCopy = dCopyImage(IMG_SourceImage, IMG_DestinationImage,...
copySrcCopy, 0, 0, 150, 200, 0, 0, 75, 100)

// Error?
IF ResCopy = True THEN
Info("The reduce operation was performed")
ELSE
Info("The reduce operation was not performed")
END
