# NAME: POSITION |
||||||
|
# |
||||||
|
# PURPOSE: To position one image relative to another image. |
||||||
|
# |
||||||
|
# DESCRIPTION: POSITION aligns or offsets one image relative to a another |
||||||
|
# image. The second image is positioned relative to the first image either |
||||||
|
# horizontally or vertically. Positioning can be done using X and Y offsets |
||||||
|
# or by specifying one controll point for each image. |
||||||
|
# |
||||||
|
# OPTIONS: |
||||||
|
# |
||||||
|
# -m method ... positioning METHOD. The choices are: offset (o) or cpoints (c). |
||||||
|
# The default=offset. |
||||||
|
# |
||||||
|
# -d direction ... positioning DIRECTION. The choices are: horizontal (h) or |
||||||
|
# vertical (v). The default=horizontal. |
||||||
|
# |
||||||
|
# -o offset ... OFFSET +X+Y values for left/top edge of second image relative |
||||||
|
# to right/bottom edge of first image. This is used when method=offset. |
||||||
|
# Position X and Y offsets may be either positive or negative. The default=+0+0 |
||||||
|
# |
||||||
|
# -l leftpt ... LEFT (first) image control x,y POINT. Values are integers>0. |
||||||
|
# The default=0,0 |
||||||
|
# |
||||||
|
# -r rightpt ... RIGHT (second) image control x,y POINT. Values are integers>0. |
||||||
|
# The default=0,0 |
||||||
|
# |
||||||
|
# -b bcolor ... BGCOLOR is the background color to fill empty spaces. Any |
||||||
|
# Imagemagick color is allowed. The default=none (transparent) |
||||||
|
# |
||||||
|
# -f format ... output color FORMAT; The choices are: RG, GB, BR or RGB. |
||||||
|
# RGB is the normal color image. RG, for example, is first image in Red and |
||||||
|
# second image in Green and any overlay will show in yellow (mix of Red and |
||||||
|
# Green). The default=RGB. |
||||||
|
# |
||||||
|
# -T trim ... TRIM output to remove any background fill areas. |
||||||
|
# Choices are: yes (y) or no (n). The default=no. Background color must be |
||||||
|
# unique in the image for the trim to work properly. |
||||||
|
# |
||||||
|
# LIMITATIONS: TRIM option only works for Imagemagick 7.0.9-0 or higher. |
||||||
|
# |
||||||
|
# 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. |
