| - | ===== Flood -- Flood fill an intensity region starting from a seed point in a 3D image volume ===== | ||
| - | |||
| - | | ||
| - | |||
| - | The FLAG argument controls options. | ||
| - | | ||
| - | FLAG values: | ||
| - | 0 - use current cursor location as seed loc. (default) | ||
| - | 1 - use origin (0,0,0) of region as seed loc. | ||
| - | 2 - use center of region as seed loc. | ||
| - | 4 - start at seed, then find nearest VALUE (or VALUE-RANGE) voxel | ||
| - | 010 - Binary: treat VALUE and RANGE as bit values | ||
| - | 020 - assume a 2-bit mask; otherwise 1 bit | ||
| - | 040 - use highest data bit(s) as mask (default is lowest) | ||
| - | 0100 - Inverse: flood values that DON'T match VAL/RANGE | ||
| - | 0200 - RANGE value is relative to neighbor (+- RANGE intensity) | ||
| - | 0400 - RANGE value is % relative to neighbor (+- RANGE %) | ||
| - | 01000 - don't include edges (voxels touching outside voxels) | ||
| - | 02000 - set edge voxels to FILL_EDGE value (2) | ||
| - | 04000 - only flood in the seed plane (default is 3-D volume) | ||
| - | | ||
| - | Values to flood depend on FLAG, VALUE, & RANGE. | ||
| - | If (FLAG & BINARY): | ||
| - | VALUE: | ||
| - | RANGE: | ||
| - | | ||
| - | Otherwise: | ||
| - | VALUE: | ||
| - | RANGE: > 0, neighbors must be within RANGE % of VALUE to be filled | ||
| - | < 0, neighbors must be within -RANGE of VALUE to be filled | ||
| - | = 0, neighbors must match VALUE to be filled | ||
| - | | ||
| - | Values being flooded will be replaced with the original value, masked by | ||
| - | DATAMASK and OR'd with FILLVALUE. | ||
| - | If FILLVALUE was not specified, it will be set to: | ||
| - | | ||
| - | If DATAMASK was not specified, it will be set to: | ||
| - | | ||
| - | | ||
| - | For binary masked data: | ||
| - | data bit 0 (1's) - ON/OFF | ||
| - | data bit 1 (2's) - FILLED/not FILLED (or INTERIOR/ | ||
| - | data bit 2 (4's) - EDGE/not EDGE | ||
| - | | ||
| - | | ||
| - | ROINUM - if this is a BLOCK ROI, filling is only done within the ROI | ||
| - | SEEDLOC - XYZ location from which to start filling | ||
| - | If SEEDLOC == 0, the seed locations is determined by the FLAG value | ||
| - | T0 - which volume to use (if nt > 1) | ||
