-Collection Overview</title><shortdesc>The Graphics Device Interface (GDI) collection is an important
-collection within the Graphics subsystem. It provides a suite of abstract

-and printers. </shortdesc><prolog><metadata><keywords/></metadata></prolog><conbody>
-<section><title>Architectural Relationship</title> <p>The GDI collection provides
-base classes and utility functions. Every graphics component ends up using
-it. The components in this collection are closely linked and provide important
-functionality. The GDI component is a low-level component in this collection,
-BitGDI is based on this and DirectGDI is a potentially faster alternative
-to BitGDI. The Colour Palette provides coloring indexing operations. </p> </section>
-<section><title>Description</title> <p>GDI consists of a large number of diverse
-APIs that cover many different aspects of graphics including graphics device
-abstraction, color value handling, linear digital differential analysis, font
-description and information, printer devices abstraction, line breaking, text
-rendering, handling of bidirectional text, text wrapper and linked font creation. </p> <p>Graphics

-is a low level component. Two key concepts related to GDI are Device (<xref href="GUID-500FC564-35E9-3B66-A0C2-1269371A2EA0.dita"><apiname>CGraphicsDevice</apiname></xref>)
-and Context (<xref href="GUID-DAD09DCF-3123-38B4-99E9-91FB24B92138.dita"><apiname>CGraphicsContext</apiname></xref>). Throughout the Graphics
-sub-system a graphics device provides a graphics context through which the
-device may be drawn to. The context maintains 'settings', such as the pen
-and brush colors and styles in use, and provides a rich API of drawing commands
-for creating graphical and textual output. </p> <p>Most display devices use
-bitmap graphics and the GDI provides specializations of both <xref href="GUID-500FC564-35E9-3B66-A0C2-1269371A2EA0.dita"><apiname>CGraphicsDevice</apiname></xref> and <xref href="GUID-DAD09DCF-3123-38B4-99E9-91FB24B92138.dita"><apiname>CGraphicsContext</apiname></xref> to
-act as base classes for bitmap devices: namely <xref href="GUID-2DEFEC47-F36E-3133-A08D-55F7C2534CC0.dita"><apiname>CBitmapDevice</apiname></xref> and <xref href="GUID-FC746873-0570-3900-AD89-42B205FDC0D3.dita"><apiname>CBitmapContext</apiname></xref>.
-These add, amongst other attributes, pixel awareness, blitting, scanlines
-and fading. </p> <p>The GDI defines abstract base classes for storing and
-manipulating fonts (<xref href="GUID-2A12FE3B-47F2-3016-8161-A971CA506491.dita"><apiname>CFont</apiname></xref>, <xref href="GUID-0CA79D2D-827F-3A20-A10C-1CC9C576E803.dita"><apiname>CTypefaceStore</apiname></xref>, <xref href="GUID-B68B7BC8-CFBA-32F4-A0BE-8378F0C105DA.dita"><apiname>CFontCache</apiname></xref>)
-and additional supporting classes and structures. </p> <p>The GDI defines
-the interface for mapping between device-specific pixels and real-world twips.
-A twip is a twentieth of a point and a point is 1/72 of an inch. That makes
-a twip 1/1440 of an inch, 1/567 of a centimeter or about 0.018mm. </p> <p>The
-GDI defines a base class for representing embedded pictures, <xref href="GUID-829D57CD-9659-347B-AAE9-5F0A0ECD555C.dita"><apiname>CPicture</apiname></xref>,
-and supporting classes. It also provides base classes, interfaces and structures
-for printing. </p> </section>

-Palette</title> <p>The <xref href="GUID-E82FABA9-9CCC-548F-99DB-EF2B9036B405.dita">Colour
-Palette component</xref> provides coloring functionality. A user can specify
-the use of a particular color, as described by a <xref href="GUID-F84C7F40-6DEB-39D1-B172-CB0CC3918E27.dita"><apiname>TRgb</apiname></xref>,
-and have that color rendered on a machine’s display device as closely as possible
-to the color specified. A related functionality allows arrays of colors to
-be stored as bitmaps, and displayed at a later date in the same manner. </p> <p>Color
-palettes also provide user-definable palette support to the GDI. A palette
-is a user-defined set of colors, which is a subset of the full range of 24-bit
-colors. This allows users the advantages of having a low bpp color mode whilst
-being able to specify the colors available in that mode. Only a palette of
-16 colors enables changing the palette. Palettes are also used to allow 24-bit
-bitmaps to be stored in a more compressed form by finding the actual number
-of different colors used in the bitmap. This creates a palette that allows
-mapping of colors to a smaller index space. The pixels of the bitmaps are
-encoded using indexes to this new index space. A palette has a size which
-is set at its creation and cannot alter the number of entries in the palette.
-Each entry in a palette is a mapping between that entry's index and a <codeph>TRgb</codeph> value.
-Palette entries can be got and set at any time between the palette's creation
-and destruction. The GDI's palette support also provides functions to find
-the nearest palette color to a requested <codeph>TRgb</codeph> color. </p> </section>
