CImage:Create
The Create method constructs a new image of specified properties and attaches it to the CImage object. Until saved, the image is not associated with any file. The image should be removed from memory using the class methods Close or delete.
|
bTrue = CImage:Create( nCols, sDatatype ) bTrue = CImage:Create( nCols, nRows, sDatatype ) |
nCols is the number
of columns in the image.
nRows is the number
of rows in the image.
sDatatype is a string
that describes the image data type (e.g., "16 bit unsigned")
On success,
this method returns true.
On failure,
this method returns false.
The image is created with the pixel values set to 0. You can change all, most, or some of the pixel values using the SetRegionVal and SetVal methods.
