proc convertToImage(png: Png): Image {....raises: [], tags: [].}: Converts a PNG into an Image by moving the data. This is faster but can only be done once. Source Edit
proc decodePng(data: pointer; len: int): Png {....raises: [PixieError], tags: [].}: Decodes the PNG data. Source Edit
proc decodePng(data: string): Png {.inline, ...raises: [PixieError], tags: [].}: Decodes the PNG data. Source Edit
proc decodePngDimensions(data: pointer; len: int): ImageDimensions {. ...raises: [PixieError], tags: [].}: Decodes the PNG dimensions. Source Edit
proc decodePngDimensions(data: string): ImageDimensions {.inline, ...raises: [PixieError], tags: [].}: Decodes the PNG dimensions. Source Edit
proc encodePng(image: Image): string {....raises: [PixieError], tags: [].}: Encodes the image data into the PNG file format. Source Edit
proc encodePng(png: Png): string {....raises: [PixieError], tags: [].}: Source Edit
proc encodePng(width, height, channels: int; data: pointer; len: int): string {. ...raises: [PixieError], tags: [].}: Encodes the image data into the PNG file format. If data points to RGBA data, it is assumed to be straight alpha. Source Edit
proc newImage(png: Png): Image {....raises: [PixieError], tags: [].}: Creates a new Image from the PNG. Source Edit
