Method Detail

getLayouts

public final LinkedHashMap<String,IDrawingLayout<DgnDrawableEntityBase>> getLayouts()

Gets the layouts map.

Specified by:

getLayouts in interface IHasLayouts<IDrawingLayout<DgnDrawableEntityBase>,DgnDrawableEntityBase>

Returns:

The layouts.

getEntities

public final List<DgnDrawableEntityBase> getEntities()

<inheritdoc></inheritdoc>

Specified by:

getEntities in interface IHasEntities<DgnDrawableEntityBase>

tryRemoveEntity

public final void tryRemoveEntity(DgnDrawableEntityBase entityToRemove)

<inheritdoc></inheritdoc>

Specified by:

tryRemoveEntity in interface IHasEntities<DgnDrawableEntityBase>

Parameters:

entityToRemove - Entity to remove

getSubUnitType

public UnitType getSubUnitType()

Gets current sub-unit type.

isCached

public final boolean isCached()

Gets a value indicating whether object's data is cached currently and no data reading is required.

Specified by:

isCached in class DataStreamSupporter

Returns:

true if object's data is cached; otherwise, false.

getVersion

public DgnFileVersion getVersion()

Gets DGN version of loaded image

getIs3DImage

public boolean getIs3DImage()

Gets a value indicating whether file is 3D or not

getWidth

public int getWidth()

Gets the image width. Defines the X-axis distance between the leftmost point of all graphic objects in the image and their rightmost point. The distance is measured in units corresponding to the value of the property Image.UnitType(Image#getUnitType)

 Uses image width value to set rasterization options.
 
 string fileName = "ExampleFile;
 string file = string.Format("{0}.dgn", fileName);
 string outPath = string.Format("{0}.pdf", fileName);
 using (FileStream inStream = new FileStream(file, FileMode.Open))
 using (DgnImage image = (DgnImage) Image.Load(inStream))
 {
     CadRasterizationOptions rasterizationOptions = new CadRasterizationOptions();
     rasterizationOptions.PageSize = new SizeF(image.Width, image.Height);
     rasterizationOptions.PageHeight = image.Height;
     rasterizationOptions.PageWidth = image.Width;
     rasterizationOptions.UnitType = image.UnitType;
     PdfOptions pdfOptions = new PdfOptions { VectorRasterizationOptions = rasterizationOptions };
     image.Save(outPath, pdfOptions);
 }
 
 

Value: The image width.

Specified by:

getWidth in interface IObjectWithBounds

Specified by:

getWidth in class Image

getHeight

public int getHeight()

Gets the image height. Defines the Y-axis distance between the bottommost point of all graphical objects in the image and their topmost point. The distance is measured in units corresponding to the value of the property Image.UnitType(Image#getUnitType)

 Uses image height value to set rasterization options.
 
 string fileName = "ExampleFile;
 string file = string.Format("{0}.dgn", fileName);
 string outPath = string.Format("{0}.pdf", fileName);
 using (FileStream inStream = new FileStream(file, FileMode.Open))
 using (DgnImage image = (DgnImage) Image.Load(inStream))
 {
     CadRasterizationOptions rasterizationOptions = new CadRasterizationOptions();
     rasterizationOptions.PageSize = new SizeF(image.Width, image.Height);
     rasterizationOptions.PageHeight = image.Height;
     rasterizationOptions.PageWidth = image.Width;
     rasterizationOptions.UnitType = image.UnitType;
     PdfOptions pdfOptions = new PdfOptions { VectorRasterizationOptions = rasterizationOptions };
     image.Save(outPath, pdfOptions);
 }
 
 

Value: The image height.

Specified by:

getHeight in interface IObjectWithBounds

Specified by:

getHeight in class Image

getDepth

public int getDepth()

Gets the image depth.

 Prints drawing's depth
 
 Image drawing = ...
 System.Console.WriteLine("Drawing's depth: " + drawing.Depth);
 
 

Value: The image depth.

Overrides:

Specified by:

cacheData in class DataStreamSupporter

getStrings

public String[] getStrings()

Gets all string values from image.

Overrides:

getStrings in class Image

Returns:

The array with string values.
