Default threshold The "magic wand" tool creates selections that consist of contiguous regions, i. e., regions that are not divided
by swaths of open space. This option determines how near each other two pixels need to be in order to be considered
contiguous.
SCALING
Default interpolation When you scale something, each pixel in the result is calculated by interpolating several pixels in the
source. This option determines the default interpolation method: it can always be changed, though, in the Tool Options
dialog. There are three choices:
None is fastest, but quite crude: you should only consider using it if your machine is very seriously speed-impaired.
Linear is the default, and is good enough for most purposes.
Cubic is the best (although it can actually look worse than Linear for some types of images), but also the slowest.
PAINT OPTIONS SHARED BETWEEN TOOLS
Brush, Pattern, Gradient You can decide here whether changing the brush etc for one tool should cause the new item to be
used for all tools, or whether each individual tool (pencil, paintbrush, airbrush, etc) should remember the item that was last
used for it specifically.
MOVE TOOL
Change current layer or path You can decide here whether changing the current level or path when using the move tool and
without pressing any key.
