Constructor.

Parameters ​

Example

import { McDbRasterImageDef } from "mxcad";

const imageDef = new McDbRasterImageDef()

Overrides ​

McDbObject.constructor

Properties ​

imp ​

• imp: any = 0

Internal implementation object.

Inherited from ​

McDbObject.imp

Accessors ​

dxf0 ​

• get dxf0(): string

Obtain the type name of the object's DXF group code, which is the same as the DXF group code in AutoCAD. For example, the type name of the line is McDbLine, and the group code value for DXF0 is: LINE and DXF0 group code values can be used for type filtering when constructing sets.

Returns ​

string

Inherited from ​

McDbObject.dxf0

objectName ​

• get objectName(): string

Get the object name.

Returns ​

string

Return object name

Example

import { McRxObject } from 'mxcad';

let obj = new McRxObject();
console.log(obj.objectName);

Inherited from ​

McDbObject.objectName

sourceFileName ​

• get sourceFileName(): string

Returns ​

string

• set sourceFileName(sPathName): void

Get or set the path of the raster image file.

Parameters ​

Returns ​

void

Example

import { McDbRasterImageDef } from "mxcad";

const imageDef = new McDbRasterImageDef();

const pathName = imageDef.sourceFileName;
Console.log (file path: ", pathName);

Methods ​

assertObjectModification ​
