Contents: Description, Arguments, Usage, Examples, Images, Sub-Functions, Related Functions, Source Supported Under Version: >1.00 Current .dvrc Version: 1.03 Description Used to blend two images of equal x and y dimension together only in x-direction. Primarily used in mosaics. Arguments and Return Values Arguments: Two v_objects containing geometrically overlapping data to be blended together, a value designating the number of pixels from the edge of the data to blend and the numeric value of non-data points. Return Value: The second v_object of the inputs will be altered containing a blended composite of the two input images. Usage Syntax: blend(src,dst,stp,ignore) src - A v_object structure containing the image you wish to add to the other image. dst - A v_object structure that will have the src image added to it. stp - An optional numeric value for the algorithm to stop counting pixels from the edge of the image. The smaller the stp value the sharper/shorter the ramp. ignore - The value of 'blank' pixels in the data. The numeric value of black space. The data elements of the two v_objects need not be the same size.
