These following parameters control how a GME effect renders the four-corner pin. Some of them are set during the analysis pass.
Filtering - This controls the quality of the rendering.
• Low - uses nearest neighbor filtering. This gives low quality but is quick to render.
• Medium - uses a bilinear filter. This gives good results and is quicker to render than high filtering.
• High - uses a sinc filter to interpolate pixels giving a sharper repair. This gives the best results but takes longer to process.
Invert - If set, then the inverse of the calculated four-corner pin is used during render.
Four Corner Pin - The corner pins calculated during the analysis pass:
• Bottom Left - the lower left corner pin.
• Bottom Right - the lower right corner pin.
• Top Left - the upper left corner pin.
• Top Right - the upper right corner pin.
