#
# NAME: MULTICROP2
#
# PURPOSE: To crop and unrotate multiple images from a scanned image.
#
# DESCRIPTION: MULTICROP2 crops and unrotates multiple images from a scanned image.
# The images must be well separated so that background color shows between them.
# The process uses a floodfill technique based upon a seed coordinate and a fuzz
# value to separate the individual images from the background of the scan.
# The correct choice of fuzz factor is very important. If too small, the images
# will not be separate. If too large, parts of the outer area of the image
# containing similar colors will be lost and the image may be separated into
# multiple parts. There are two unrotate methods. The first uses the IM deskew
# function, but is limited to 5 degrees of rotate or less. The second uses my
# unrotate script. It allows much larger rotations, but will be slower. If
# using the second method, my unrotate script must be downloaded and installed.
#
# IMPORTANT: The images in the scanned file must be well separated in x and y
# so that their bounding boxes do not overlap. This is especially important
# if the images have a significant rotation.
#
# The output images will be named from the specified outfile and -000, -001,
# -002 etc, will be appended before the .suffix.
#
# Arguments:
#
# -c coords ... COORDS is any location within the background (non-image) area
# for the algorithm to find the background color. It may be specified in terms
# of gravity parameters (NorthWest, North, NorthEast, East, SouthEast, South,
# SouthWest or West) or as a pixel coordinate "x,y". The default is the
# upper left corner = NorthWest = "0,0".
#
# -b bcolor ... BCOLOR is the background color to use for flood fill instead
# of extracting this color from the image. This is useful when an image has
# no borders so that the sub-images are hard against the edges. The bcolor
# will be used to put a one pixel border around the image and coords will be
# set to 0,0. Any valid IM color is allowed. The default is to use option -c.
#
# -f fuzzval ... FUZZVAL is the fuzz amount specified as an integer percent
# value between 0 to 100 (without the % sign). The correct choice of fuzz
# factor is very important. If too small, the images will not be separate.
# If too larger, parts of the outer area of the image containing similar
# colors will be lost and the image may be separated into multiple parts.
# Typical values are probably between 5 and 20 percent. The default=10
#
# -d discard ... DISCARD any region that has an area smaller than the
# specified discard size. Values are integer>0. The default is to keep all
# regions.
#
# -u unrotate ... UNROTATE is the unrotation method. Choices are: 1, 2 or 3.
# The default is unrotate=1, which is fast and uses the IM -deskew function,
# but is limited to images that are rotated no more than 5 degrees in the scan
# and generally a light background color. Option unrotate=2 uses my unrotate
# script. It can handle larger rotations, but is slower. If using the latter
# method, my unrotate script must be downloaded and also installed so that it
# is available for this script to use. Option unrotate=3 makes no attempt to
# unrotate the images.
#
# -i innertrim ... INNERTRIM trims inside the cropped area to an orthogonal
# rectangle. Requires my script, autotrim. The choices are: yes or no.
# The default=no.
#
# -e extend ... EXTEND crop on each side for the output images in pixels.
# The extended region will come from the background of the image. Values are integers.
# Positive makes the results larger. Negative makes the results smaller. Positive
# values are only allowed for unrotate=3 (no unrotation) and innertrim=no. The default=0.
#
# -m mask ... MASK provides several options for reviewing the initial mask that
# is generated by the fuzz value. The choices are: view (display to X11 window),
# save (to disk) along with the images, or output (without processing the images).
# The default is to simply process the images without showing or saving the mask.
# If using the view mode, then processing will stop until the image is closed.
# But this allows you to then kill the script if the mask is not appropriate.
# A good approach is to use the output mode repeatedly with various fuzzvals
# until a reasonable mask is created. Note that the mask must separate the
# images, but the background can "eat" a little into the images so long as no
# full edge is lost or the images is split into multiple parts.
#
# -t threshold ... THRESHOLD on the number of objects. The script aborts, if
# more than the threshold number of objects are detected. Value must be
# integers greater than 0. The default is no abort and keep all objects.
# To avoid an abort, use the -d discard option.
#
# -r resize ... RESIZE amount in percent to scale the image down. Values are floats>0.
# The default is no resizing. This is useful to improve speed and floodfilling
# when you have a large image, especially if the background is grainy. Note: do not
# include the % symbol.
#
# -D density ... DENSITY to use when reading a single page of a PDF. Multipage pdf
# files are not permitted. Values are integers>0. The default is no assigned density.
#
# -S sortval ... SORT regions by their upper left bounding box x,y coordinates
# rounded to the specified positive integer increment. The default is
# no sorting.
#
# -s showstats ... SHOWSTATS shows the connected components statistics.
# Choices are: yes (y) or no (n). The default=no.
#
# -v ... keep VIRTUAL CANVAS. The default is not to keep virtual canvas. This option
# is only valid for -u=3 (no unrotate) and for output format that supports virtual
# canvas such as PNG or TIFF.
#
# REQUIREMENTS: IM 6.8.9.10 due to the use of -connected-components.
# If using unrotate method 2, then my script, unrotate, is required.
# If using innertrim, then my script, autotrim is required.
#
# CAVEAT: No guarantee that this script will work on all platforms,
# nor that trapping of inconsistent parameters is complete and
# foolproof. Use At Your Own Risk.
