Contents: Description, Arguments, Usage, Examples, Related Functions Supported Under Version: >1.69 Current Davinci Version: 2.27 64-bit Safe: Yes Description Resizes a multiband image/numerical data upwards or downwards Arguments and Return Values Input: Data array and factor information Output: An resized array Usage Syntax: image_resize(data = VAL [, factor = DOUBLE] [, xfactor = DOUBLE] [, yfactor = DOUBLE ] [,width = INT ] [,height = INT] [,lockratio=bool] [,interp={'bilinear' | 'bicubic' | 'none'}] [,ignore = DOUBLE]) 'factor' - Resize factor 'xfactor' - Resize x factor 'yfactor' - Resize x factor 'width' - Resize an image to a specified width 'height' - Resize an image to a specified height 'lockratio' - Locks the image aspect ratio 'interp' - Interpolation algorithm. For scaling up the available options are 'bicubic', 'bilinear' or 'none'. For scaling down it uses the average box algorithm by default or 'none' if specified.
