FAQ
CT1 to HPG Conversion
What are CT1 files?
CT1 is a raster image file extension used for CALS Type 1 files, defined by the U.S. Department of Defense Computer-aided Acquisition and Logistic Support (CALS) initiative in the MIL-R-28002 specification, and later incorporated into MIL-STD-1840 for the exchange of technical documentation. A file of this type contains a single black-and-white page, stored as a bilevel image compressed with the CCITT Group 4 (ITU-T T.6) method, which made it well suited to scanned engineering drawings, manuals, and archival paper documents. The page is preceded by a fixed-length text header that identifies the source document, the figure, the document class, the pixel dimensions, the page orientation, and the scanning density. The format supports no color or grayscale, and remains in use in legacy technical document archives.
What are HPG files?
HPG is a vector image format created in a standard programming language called HPGL (Hewlett-Packard graphics language). Other extensions created in this language include PLT, HP2 and PL2. All are called "plotter files" and are created by drawing programs such as AutoCAD to be printed using a device specialized in vector graphics. An HPG file uses a line series of two-letter codes to render an image and can also include parameters.
