USAGE: diagcollage [-h or -help]

-s .... size ......... square output size; even integer>0; default=400
-b .... bcolor ....... border color; default=white
-t .... thick ........ border thickness; even integer>>; default=10
-d .... direction .... direction of 5 deg rotation; p (positive) or
...................... n (negative); default=p
-g1 .... gravity1 .... crop gravity setting for image 1; default=center
-g2 .... gravity2 .... crop gravity setting for image 2; default=center
-g3 .... gravity3 .... crop gravity setting for image 3; default=center
-c1 .... crop1 ....... crop offsets for image 1; default="+0+0"
-c2 .... crop2 ....... crop offsets for image 2; default="+0+0"
-c3 .... crop3 ....... crop offsets for image 3; default="+0+0"

PURPOSE: Collages three images in a diagonal orientation.

DESCRIPTION: DIAGCOLLAGE collages three images in a diagonal orientation. The first image will span the top half (before rotation) and the other two images will be on the bottom left and bottom right quadrants, respectively.

ARGUMENTS:

-s size ... SIZE is the even square output size. Values are even integers>0. The default=400.

-b bcolor ... BCOLOR is the border color. Any valid IM opaque color is permitted. The default=white.

-t thick ... THICK is the border thickness. Values are even integer>0. The default=10.

-d direction ... DIRECTIONS of the 5 deg rotation. Values are: p (positive) or n (negative). The default=p (positive).

-g1 gravity1 ... GRAVITY1 is the crop gravity setting for image 1. Any IM gravity setting is allowed. The default=center.

-g2 gravity2 ... GRAVITY2 is the crop gravity setting for image 2. Any IM gravity setting is allowed. The default=center.

-g3 gravity3 ... GRAVITY3 is the crop gravity setting for image 3. Any IM gravity setting is allowed. The default=center.

-c1 crop1 ... CROP1 is the crop offsets for image 1. The format is +-X+-Y. The default="+0+0".

-c2 crop2 ... CROP2 is the crop offsets for image 1. The format is +-X+-Y. The default="+0+0".

-c3 crop3 ... CROP3 is the crop offsets for image 1. The format is +-X+-Y. The default="+0+0".

What the script does is as follows:

  • Crops each image appropriately, then resizes, then crops again,
    then adds a border where needed
  • Appends them with the first on top and the other two side-by-side below
  • Rotates, crops and finally adds a final border

This is equivalent to the following IM commands for
the case of horizontal append:

  • osize=`convert xc: -format "%[fx:$size-2*$thick]" info:`
  • size=`convert xc: -format "%[fx:1.1*$size]" info:`
  • size2=`convert xc: -format "%[fx:$size/2]" info:`
  • thick2=`convert xc: -format "%[fx:$thick/2]" info:`
  • if [ "$direction" = "p" ]; then
    sign="+"
    elif [ "$direction" = "n" ]; then
    sign="-"
    fi
  • convert \

    -crop ${size}x${size2}+0+0 +repage -background $bcolor -gravity south -splice 0x$thick \) \

    \( -clone 1 -clone 2 +append \) \
    -delete 1,2 -append \
    -background $bcolor -rotate ${sign}5 +repage \
    -gravity center -crop ${osize}x${osize}+0+0 +repage \
    -bordercolor $bcolor -border $thick "$outfile"
