The .i.IFF.i. format is described in the Amiga ROM Kernel Manual, and sample programs to read and write such files may be found i The file formats used by the Sculpt series of programs for the Amiga are constantly changing, through the addition of new chunk types and the definition of reserved 'padding' bytes in existing chunks. In most cases this will not present problems either Image files Images are written as .i.ILBM; IFF files and need little further explanation here, since they conform to the published standards. Because of the variety of image size and mode that Sculpt Animate uses, programs which intend to use these images shouldn' Images saved in conjunction with frame buffer usage are non-standard, but follow the ILBM format. These images have no CMAP chunk, so the bit planes represent actual 24-bit color intensity values: 8 planes each of red, green, and blue--stored in that Scene files Scene files contain a number of data chunks.
