for what?
ok ... lets do some basics... our temp picutre has 64 columns?
our source (my desktop) is 1600 columns wide?
... so i Have to grab every 64th Pixel?
a simple calculation would result into
destination column 0: --> source column 0
destincation column 63: --> source column 1575 ... so we will lose 25 pixel to the right?
so m_lShift is the value we have to move the "Grab Raster to right" so that
destination column 0: --> source column 12
destincation column 63: --> source column 1587 ... so we will lose 12 pixel to the right and 12 to the left.. a nice small ignored Border around...
that same happens to the row position...
