WINAPI can read and store files in all graphics formats supported by DaVinci. Printing and internal differentiation between metafiles and bitmaps is also supported.
However, MFC can only import and export bitmap data formats. Metafiles (vector graphics) must first be converted into bitmaps for use with MFC functions.
DAVDEMO will open images in DaVinci’s supported formats, display them onscreen, and export them to any of the compatible supported formats. The demo application works with the image internally as a device-dependent bitmap (DDB). Palette conversion to 256 colors and scrolling are also demonstrated.
DAVIEW, like WINAPI, is based on Windows API functions, and contains additional functions such as control over the flag values used by the ipImportInd and ipExportInd functions. It also demonstrates how to display of DXFs as white lines on black backgrounds, image rotation, and modification of color depth among others.
Pascal and Delphi users may also wish to explore the GETDIB.PAS and GETTEST.PAS sample units. They demonstrate how DIB data can be addressed in PASCAL applications, and provide useful, ready-to-use utility graphics functions.
