CImage:TableToCol

The TableToCol method pastes (imbeds) a 1-dimensional array into a column of the CImage object. The length of the array determines the row extent of the column. The table is imbedded at the specified integer-valued (column, row) offsets. This method is similar to the Imbed method, except that it imbeds a 1-dimensional array rather than another CImage. The inverse operation, copying a CImage column to a 1-dimensional array, uses the ColToTable method.

Syntax

nResult = CImage:TableToCol( tbl, nColMin, nRowMin )

bullet.gif    tbl is a 1-dimensional array to be imbedded as a column in the CImage.

bullet.gif    nColMin and nRowMin are the integral (column, row) offsets to the corner where tbl is imbedded.

bullet.gif    On success, this method returns nResult = 1.

bullet.gif    On failure, nResult contains the following error codes:

bullet.gif    -1: The 1-dimensional array tbl is not valid.

bullet.gif    -2: Not enough parameters were passed.

bullet.gif    -3: Invalid CImage object.

bullet.gif    -4: Internal error.

bullet.gif    -5: The column coordinate is invalid.

bullet.gif    -6: The row coordinate is invalid.

Example

Suppose that a CImage I exists. The following script imbeds a column of values into the CImage. The imbedding corner is set to coordinates (100,250):

nMinC = 100 ; nMinR = 250

-- position the corner of tbl at these offsets in I

tbl = {}

-- create a table (this will be a 1-D table)

tbl[1] = 15.3

-- assign the first value

tbl[2] = 12.592

-- assign the second value

-- complete the column...

 

nRet = I:TableToCol( tbl, nMinC, nMinR )

-- imbed tbl as a column at corner (100,250)

if nRet != 1 then Printf("Err %d\n", nRet) end

-- an error occured
