# Input sources: Full, selection, dimensions, latest taken screenshot

# Filters: Resize, drop-shadow
|

# Output sources: File, clipboard

# Screenshot default: .png

# Each screenshot has 1 or more input sources and 1 or more output sources. The
|
|
||||||
# image extention is determined by the output file, --extension option, or
|
|
||||||
# defaults. Regardless of extension, every screenshot is first saved as a
|
|
||||||
# lossless PNG then converted to other formats. All intermediate files are
|
|
||||||
# saved in a temporary directory set by the --tmp-dir option
|
|
||||||
#
|
|
||||||
# Setting the --tmp-dir alongside the --resize option will modify the latest
|

# image in that directory
