### Process: ImageDecoder ### Process: ImageDecoder
This process can decode images (PNG, JPEG, BMP, ICO, PBM, etc.) into bitmaps. Each image is decoded in a fresh **ImageDecoder** process. These are strongly sandboxed and can't do much except receive encoded bitmap data and return a bitmap to **WebContent** if decoding successful.
