NAME¶
xmorph - image warping and dissolving (morphing) for X window system morph - command line interface image morphing programSYNOPSIS¶
xmorph [-start srcimgfile [-finish destimgfile]] [-src srcmeshfile [-dst dstmeshfile ]] [-help] morph [-start srcimgfile [-finish destimgfile]] [-src srcmeshfile [-dst dstmeshfile ]] [-out outimgfile ] [-mt morphtween ] [-dt dissolvetween ] [-help]DESCRIPTION¶
xmorph is a digital image warping and dissolving program, also known as a "morphing" program. It runs under the X Window System. The primary use of xmorph is to generate and modify meshes which control the shape of an image. xmorph also has the capacity to dissolve images together, and to generate a sequence of warped and dissolved images. When this sequence is made into a movie, it is called a "morph". morph is a morphing program with no graphical user interface. morph performs image warping and dissolving but provides no means to create or modify meshes. The intent is to use morph after meshes have already been generated with xmorph. Since morph has no GUI, it can be run as a background job and can be distributed over many machines or processes. This parallelization of the task can significanly speed up the image processing. morph can run on machines which have no display whatsoever, and is therefore very portable. Both xmorph and morph use a library called libmorph which can be used separately in the creation of other morphing programs. If imgfile names are provided on the command line, then those images are loaded in. Otherwise, xmorph generates images to be used in lieu of images provided by the user. Images may be loaded from menus within xmorph. xmorph has built-in help pages that answer questions about the details of its use. Run xmorph and look at the online help for more information.OPTIONS¶
- -start srcimgfile
- Read the srcimgfile as the "source" image.
- -finish destimgfile
- Read the destimgfile as the "destination" image.
- -src srcmeshfile
- Read the srcmeshfile as the "source" mesh.
- -dst destmeshfile
- Read the destimgfile as the "destination" mesh.
- -help
- Display command line options.
MORPH OPTIONS¶
- -out outimgfile
- Write the the output image to outimgfile .
- -mt morphtween
- Use morphtween as the warping tween parameter. Values are from 0 to 1. 0 means that the shape of the output is according to the source mesh. 1 means that the shape is according to the destination mesh. Default value is 0.
- -dt dissolvetween
- Use dissolvetween as the dissolve tween parameter. Values are from 0 to 1. 0 means that the image of the output is according to the source image. 1 means that the image is according to the destination image. Negative values indicate that a sigmoid sharpening function is to be applied to make the dissolving more concentrated to values near 0.5. The idea is that the dissolvetween value should be the negative of the morphtween value in order to have the dissolve be more rapid during middle values of the warp tween parameter, and less rapid otherwise. This makes the morph more visually acceptable. Default value is 0.
