Raster Image not visible when rotated (C# .NET API)

L D · February 2017

Hello,

I am inserting a raster image with C# .NET API, it works fine, but when I select the raster image in BricsCAD and rotate it, the raster image is not visible, only its frame. Curiously, if the raster image is rotated a multiple of 90 degree ,it works fine, but any other angle does not.

¿Any other thing is needed to make this works or it is a bug in the API? If a raster image is inserted directly with BricsCAD it works fine.

[code] AutoCAD.Common.TransactionManager trans = new AutoCAD.Common.TransactionManager(document);

trans.StartAcadTransaction();

ObjectId imageDictId = RasterImageDef.GetImageDictionary(document.Database);

if (imageDictId.IsNull)

{

imageDictId = RasterImageDef.CreateImageDictionary(document.Database);

}

DBDictionary imageDictionary = trans.Transaction.GetObject(imageDictId, OpenMode.ForRead) as DBDictionary;

ObjectId acImgDefId;

RasterImageDef acRasterDef = new RasterImageDef();

acRasterDef.SourceFileName = @C:\test.png;

imageDictionary.UpgradeOpen();

acImgDefId = imageDictionary.SetAt(rasterName, acRasterDef);

imageDictionary.DowngradeOpen();

trans.Transaction.AddNewlyCreatedDBObject(acRasterDef, true);

RasterImage acRaster = new RasterImage();

acRaster.ImageDefId = acImgDefId;

Vector3d width = new Vector3d(1000, 0, 0);

Vector3d height = new Vector3d(0, 1000, 0);

Point3d insPt = new Point3d(0, 0, 0.0);

CoordinateSystem3d coordinateSystem = new CoordinateSystem3d(insPt, width, height);

acRaster.Orientation = coordinateSystem;

acRaster.ShowImage = true;

BlockTable acBlkTbl = trans.Transaction.GetObject(document.Database.BlockTableId, OpenMode.ForRead) as BlockTable;

BlockTableRecord acBlkTblRec = trans.Transaction.GetObject(acBlkTbl[BlockTableRecord.ModelSpace], OpenMode.ForRead) as BlockTableRecord;

acBlkTblRec.UpgradeOpen();

acBlkTblRec.AppendEntity(acRaster);

acBlkTblRec.DowngradeOpen();

trans.Transaction.AddNewlyCreatedDBObject(acRaster, true);

acRaster.AssociateRasterDef(acRasterDef);

trans.Commit();[/code]

What a mess with the code format, I post it again:

AutoCAD.Common.TransactionManager trans = new AutoCAD.Common.TransactionManager(document);
