TwoPassConfig¶

Overview¶

Type TwoPassConfig¶

Raw type for a TwoPassConfig

Notes about relationships for the various properties (how we align bins and tiles, index things, including pixels):

raster-width, raster-height tile-width, tile-height ---- ensure tile-x < tile-width and tile-y < tile-height!!! (tile index = tile-x + tile-y * tile-width) num-tiles = tile-width * tile-height bin-width, bin-height --- ensure bin-x < bin-width and bin-y < bin-height!!! (bin index = ( rel-bin-x + rel-bin-y * 16 ) + tile-index << 8?) - guarantee 256 bins per tile? BUT don't compute ones outside? num-bins = 256 * num-tiles --- note not all will be used

tile-size: 16 * bin-size bin-size: usually subdivide-size (16), but could be 15 or 13 if bilinear/bicubic

filter: box, bilinear, bicubic adjust-filter-size: 1 or THE SCALE of the filter --- if non-1, we won't use the "grid filter" approach filter-radius (how much we need to expand by) [defer] tile/bin enabled mask (whether it should compute or write out)
