PNG graphics format information and DataType
.description
The DataType reads bitmap images stored in the PNG (Portable Network
Graphics) format.
The DataType supports all types of PNG-encoded images. Grayscale images
are converted to palette-based images. This version of the DataType
supports 24-bit DataType tag extensions, and can pass true color data to
supporting applications (e.g. Cybergraphics software). In a palette-based
environment, true color (up to 48-bit) images are dithered using a fast
Floyd-Steinberg method.
This DataType also reads the Author, Copyright and Comment fields
(DTA_ObjAuthor, DTA_ObjCopyright and DTA_ObjAnnotation DataType
attributes).
Two versions of the DataType are included here: 68000 and 68020+.
Also included, an example of DataType-based image viewer (ViewDT), with
source code.
