A.2.57 4D CAD 1.0

(363) Improved the appearance of the printing clip box on Windows.
(364) Implemented raster images on Windows. This affects the following methods:
CADAddImage , CADGetImageInfo , CADGetImageFileInfo , CADGetImageFile , CADImportImage , CADLoadFromFile , CADLoadFromPict , CADStoreToPict , CADStoreToFile , CADObjImage .
- CAD uses an internal (lossles) compressor for raster images. The compressor is quite suitable for computer graphics, but ineffective for photographic images. QuickTime compression and an internal (lossles) compressor for photographic images are left to a future version.
- On Windows, CADLoadFromPict and CADLoadFromFile can not load CAD drawings that contain raster images stored on Macintosh with a CAD release prior to 1.0. To load these on Windows, restore them on Macintosh with CAD 1.0 (or later).
- On Windows, selected or color-attributed raster images may not look good. This is due to limitations of Windows graphics.
- On Windows NT, displaying large bitmaps takes a lot of (slow) virtual memory. The cause is probably a bug in Windows NT (that may even crash the Windows NT kernel). Try decreasing the number of colors in the Display Control Panel.
- For the same reason, large bitmaps may not print on Windows NT.
- Raster images on Windows can be mirrored, both on screen and on paper. However, they can not (yet) be rotated. Please, note that this affects thePrintOrientation parameter of CADSetPrintSpecs.
- On Windows, CADGetImageFileInf and CADImportImage use QuickTime for Windows. If QuickTime isn’t installed, error kQuickTimeNotInstalled is returned.
- On Windows, QuickTime is started when CADGetImageFileInf or CADImportImage are called the first time. Starting QuickTime on Windows is a slow operation.
- On Windows, CADObjImage will return kCADImplementationRestriction if theRasterImageFlag is set to kCADTrue . This is due to bugs in ASINTPPC.DLL.
- On Windows, theShowImportFilesOnlyFlag of CADGetImageFile is ineffective. Instead, a filter path is used (located in a STR# resource ID 18701, 17).
(365) CADGetImageFileInf now returns an error if it can’t create a preview picture. Previously, it returned an empty preview picture. Consequently, you may have to call CADGetImageFileInf a second time, setting thePreviewPictureFlag to kCADFalse .
(366) On Windows, creating a preview picture with CADGetImageFileInf, takes a lot of time and memory. The problem is located in QuickTime for Windows.
(367) API change − removed theHatchID parameter of CADObjSquare , CADObjRectangle , CADObjPolyLine , CADObjCircle , CADObjCircleArc , CADObjEllipse and CADObjEllipseArc .
