CRect:Set
The Set method initializes the 4 data members of the CRect to specific values or to values in another CRect. To initialize to a full image, use SetToImage.
|
CRect:Set( nXmin, nXmax, nYmin, nYmax ) |
nXmin, nXmax, nYmin,
nYmax are numbers that specify the rectangle limits in terms
of pixel
coordinates. They may be positive or negative.
CRect:Set( CRect )
TheCRect argument is copied to the data members of the
current CRect.
The following script fragment initializes the 4 dimensions of the CRect as xmin=100, xmax=200, ymin=40.5, ymax=300.25. Note the order in which the values are passed, with both x values first, followed by both y values:
|
R = CRect:new() |
-- create a CRect object |
|
R:Set(100,200,40.5,300.25) |
-- specify the values |
