Terminology
What some non-obvious terms mean in Blitline
There are some image processing terms that may not make sense to those unfamiliar with ImageMagick or Blitline.
GRAVITY
Gravity defines where a selection should be placed within the context of an image.
For example: WestGravity would mean "left-align" the image
There are 10 different possible gravity settings:
- CenterGravity
- NorthWestGravity
- NorthGravity
- NorthEastGravity
- EastGravity
- SouthEastGravity
- SouthGravity
- SouthWestGravity
- WestGravity
COMPOSE OPERATIONS
During a composite operation (which overlays one image on top of another), there are many different ways the images can be combined together.
You can read more about them here: https://legacy.imagemagick.org/Usage/compose/
Generally you will normally just use the defaults.
