%description
Uses convolution-based techniques to generate simulated camera bokeh,
depth of field, and other camera effects, using an image and an optional
depth map. Accepts both filename inputs and in-memory array
representations of images and matrices, including common raster formats
such as 'JPEG', 'PNG', 'TIFF', 'TGA', 'BMP', 'PSD', 'GIF', 'HDR', 'PIC',
'PNM', 'DNG', and 'EXR'. Includes functions to perform 2D convolutions,
color correction, colorspace conversion, image/matrix reorientation and
resizing, image and text overlays, exposure adjustment, camera vignette
effects, and image titles.
