composite_alpha_outline_image

Internal helper that composites the original source image over
the generated outline using source-over alpha compositing. The outline is the
backdrop and the source image is the foreground. Colors are treated as
straight, non-premultiplied alpha, using
<code>Ao = Af + Ab * (1 - Af)</code> and
<code>Co = (Cf * Af + Cb * Ab * (1 - Af)) / Ao</code>. Fully transparent output pixels
are forced to black to avoid carrying arbitrary color values.

internal

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.
