Insert picture in a .dwg

[yannick]

Hello,

I would like to insert a picture (.jpg or .ico or.bmp) in a new layer of a dwg file.
I would like to create a block which contain a picture and CADMtext. After i will add some insert of this block.

But i don't find how to load picture. CADImageDef.LoadFile() is protected so i can't call it.
I don't understand difference between CADImageDef and CADImageEnt.

EditorDemo allow to add some picture by using class EntitiesCreator. But I don't get code of EntitiesCreator, is it possible to get it in order to copy some code?

Best regards, yannick.

Hello!

Please try the following code:

Code: Select all

{
	if(this.cadImage == null) 
	{
		this.cadImage = new CADImage();
		this.cadImage.InitialNewImage();
		this.cadImage.UseDoubleBuffering = false;
	}
	this.cadImage.UseDoubleBuffering = false;

	[color=#40FF80]//add MText[/color]
	CADMText entMText = new CADMText();
	entMText.Text = "Hello World!";
	entMText.Color = Color.Red;
	entMText.Point = new DPoint(0,0,0);
	entMText.Height = 10;						
	entMText.Loaded(this.cadImage.Converter);						
	this.cadImage.Converter.OnCreate(entMText);		
	
	[color=#40FF80]//add ImageEnt[/color]
	CADImageEnt entImage = new CADImageEnt();
	string tmp = "c:\\Test.bmp";
	if(! System.IO.File.Exists(tmp)) return;
	Bitmap bmpTmp;
	try
	{
		bmpTmp = new Bitmap(tmp);
	}
	catch
	{
		return;
	}
	entImage.SetImage(bmpTmp);
	entImage.Color = Color.Bisque;			
	entImage.Point = new DPoint(0,0,0);
	entImage.Point1 = new DPoint(bmpTmp.Width, -bmpTmp.Height,0);
	entImage.Point2 = new DPoint(0,0,0);
	entImage.Point3 = new DPoint(1, 1, 1);
	entImage.Rotate = 0;
	entImage.LineWeight = 0.1;
	entImage.Loaded(this.cadImage.Converter);
	entImage.Point2 = new DPoint(0, 0, 0);			
	this.cadImage.Converter.OnCreate(entImage);	

	CADBlock entBlock = new CADBlock();
	entBlock.Name = "Image Block";
	entBlock.Visibility = true;
	entBlock.Visible = true;
	entBlock.AddEntity(entImage);			
	entBlock.AddEntity(entMText);			
	this.cadImage.Converter.Blocks.Add(entBlock);
	this.cadImage.Converter.OnCreate(entBlock);
	this.cadImage.Converter.Loads(entBlock);

	CADInsert entIns = new CADInsert();
	entIns.Block = entBlock;
	entIns.Point = new DPoint(0,0,0);
	entIns.Visibility = true;
	this.cadImage.Converter.Entities.Add(entIns);
	this.cadImage.Converter.OnCreate(entIns);
	this.cadImage.Converter.Loads(entIns);
						
	this.cadPictBox.Invalidate();
}

But i don't find how to load picture. CADImageDef.LoadFile() is protected so i can't call it.
I don't understand difference between CADImageDef and CADImageEnt.

Current version of CAD Import .NET uses CADImageDef for inner needs. Theoretically relations between CADImageDef and CADImageEnt are just like between CADBlock and CADInsert. CADImageDef and CADBlock contain an object. CADImageEnt and CADInsert define insert parameters. Such behaviour will be implemented in the next versions of the library.

EditorDemo allow to add some picture by using class EntitiesCreator. But I don't get code of EntitiesCreator, is it possible to get it in order to copy some code?

Unfortunately this is impossible.

Hello Sergey,

I thank you for your previous answer. I managed to insert picture in block.
Now i would to show a text under the picture.
Each inserted entity represent an user in map. The picture is every time the same but i would like to show the name of the user under the picture.
I think to use attribut. For every inserted entity i add an CADAttrib that containts the name and i would like to show this attribut.
I test it but value of attribut doesn't appear in map and when i select the inserted entity with mouse clic then the selected area is very bigger than my picture.

Is an attribut visible in map?
Exist it a solution with only one block or must i create one block and one inserted entity for each user?

More over can i save my map with picture to dxf?
Currently i create CADImage like this :
Byte[] tabByte = ......
MemoryStream ms = new MemoryStream(tabByte);
Image imageObj = Image.FromStream(ms);
entImage.SetImage(imageObj);

Best regards, yannick.

More over can i save my map with picture to dxf?

Current version of CAD Import .NET does not allow saving raster images in to DXF file format. We will inform you when it is available.

Thank you Sergey, it works fine.

How can i use arial font for user name showing by attribut? I know format font for MText but not for attribut.

Hello Yannick,

Unfortunately CAD Import .NET v.6.3 does not allow changing font for attributes.
