You should use TIFFReadScanline() to read each scanline into memory you have allocated.
Good advice. Especially if you plan to next explain how tiling issues require another low-level approach. And explain that the interface will still work only with these 4bit images, or either explain planarconfiguration issues, subsampling issues, all color convertion issues, etc.
