CImage:ColToTable The ColToTable method copies the pixels of a CImage column into a 1-dimensional array. If the CImage has a numeric pixel type (e.g., "ushort", "float", etc.) then the array has numeric values. If the CImage has an rgb pixel type, then the array has rgb strings as values, for example "255,0,0" for pure red. See Pixel Types. The inverse operation, pasting a column into a CImage, is done using the TableToCol method. Syntaxlua_table = CImage:ColToTable(nCol) lua_table = CImage:ColToTable(nCol, nRowMax) lua_table = CImage:ColToTable(nCol, nRowMin, nRowMax)
ExamplesThe following script creates a 1-dimensional table consisting of image column 40. The number of table elements equals the number of rows in the image:
The next script creates a 1-dimensional table consisting of image column 40 over rows 200 to 300. The table will have 101 elements:
