How Styles Define Images

RetroCapture images are generated using an image-style definition as follows:

• A passphrase is generated according to this image-style's specification.
• All style objects are reset and prepared to create a new image. For example, the 'twist' warp-style selects a new angle of twist at random for the image.
• An empty, monochrome (grayscale) image canvas is created in memory, painted white.
• Each paint-style in this image-style is applied in turn to the canvas.
• An edge-fade is applied, if requested in the image-style.
• The passphrase text is applied to the canvas, using each warp-style in this image-style in turn.
• The monochrome canvas is recolored using the image-style's color.
• The canvas is rendered as an interlaced GIF89a image, which is either output to file or provided as a byte-stream through the Java API.
• A mapping entry is made for the image and its passphrase.
