Format of a text file of a raster mask |
The file should have the quantity of lines corresponding to the height of a raster. Each line of a text file describes a corresponding ruler of pixels of a raster. Passing by a raster is doing from top to down, i.e. the uppermost ruler of pixels corresponds to the first line of a file, etc. Into a file of a mask the numbers of displayed pixels of the raster standing on border of invisible zones are entered. The line of a mask file begins from the numerical value designating quantity of alternating zones in a ruler of pixels: 1 - all pixels of a ruler are displayed; 2 - the ruler of pixels contains displayed and not displayed sites; 3 - the ruler of pixels contains 3 sites: displayed, not displayed, displayed; etc. If all ruler of pixels is displayed the values are entered into a mask: 1 (width-1), where width - width of the image of a raster in pixels. Example of a text file of a mask for the raster image with a width 4043 pixels:
