# 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. |
