I have a .DWG file with block . try to insert image into it. but it fail

Version : 4.0.38.187


C# Code:
string templateFilePath = "I:\\AUTOCAD_10589436.dwg";
try
{

if (System.IO.File.Exists(templateFilePath))
{


DxfModel modelTemp = DwgReader.Read(templateFilePath);
DxfBlock result = new DxfBlock("TITLEBLOCK");

DxfModel DestinationModel = DwgReader.Read(templateFilePath);

//
Point3D minToFitIn = new Point3D(30, 60, 0);
Point3D maxToFitIn = new Point3D(558, 390, 0);
BoundsCalculator boundsCalculator = new BoundsCalculator();
boundsCalculator.GetBounds(DestinationModel);
Bounds3D bounds = boundsCalculator.Bounds;
double scale = 1;
Matrix4D to2DTransform = DxfUtil.GetScaleTransform(bounds.Min, bounds.Max, minToFitIn, maxToFitIn, out scale);

BoundsCalculator boundsCalculatorTemplate = new BoundsCalculator();
boundsCalculatorTemplate.GetBounds(modelTemp);
Bounds3D boundsTemplate = boundsCalculatorTemplate.Bounds;
Matrix4D to2DTransform1 = DxfUtil.GetScaleTransform(boundsTemplate.Min, boundsTemplate.Max, minToFitIn, maxToFitIn, out scale);

CloneContext cT = new CloneContext(modelTemp, DestinationModel, ReferenceResolutionType.CloneMissing);
cT.RenameClashingBlocks = true;

#region working mapping hardcoded
int iBlkCheck = -1;

List<string> sBlocks1 = new List<string>();

sBlocks1.Add("dxfImgBlock");

if (sBlocks1 != null && sBlocks1.Count > 0)
{
if (!DestinationModel.Blocks.Contains(sBlocks1[0]))// if the title block is not inserted already inserted it will map the properties and will insert the title block.
{

DxfImageDef imageDef = new DxfImageDef(modelTemp);
imageDef.Filename = "I:\\Account.png";
imageDef.Size = new Size2D(118d, 179d);
imageDef.DefaultPixelSize = new Size2D(1d, 1d);
imageDef.ImageIsLoaded = true;
modelTemp.Images.Add(imageDef);

Point3D insertionPoint1 = new Point3D(16d, 3d, 0d);
{ // default size
DxfImage image = new DxfImage();
image.ImageDef = imageDef;
image.InsertionPoint = insertionPoint1;
image.ImageDisplayFlags = ImageDisplayFlags.ShowImage;
image.SetDefaultBoundaryVertices();
//image.XAxis=
//image.YAxis =
modelTemp.Entities.Add(image);
DxfBlock dxfImgBlock = new DxfBlock("QR_ImgBlock");
modelTemp.Blocks.Add(dxfImgBlock);
dxfImgBlock.Entities.Add(image);
}


foreach (DxfEntity sourceEntity in modelTemp.Entities)
{
DxfEntity clonedEntity = (DxfEntity)sourceEntity.Clone(cT);
result.Entities.Add(clonedEntity);
}


cT.ResolveReferences();

DxfInsert odx = new DxfInsert(result);
double xCord = bounds.Corner1.X;
double yCord = bounds.Corner1.Y;
odx.InsertionPoint = new Point3D(0, 0, 0);

DestinationModel.Blocks.Add(result);
DestinationModel.Entities.Add(odx);
foreach (DxfLayout layout in DestinationModel.Layouts)
{
layout.Entities.Add(odx);
}


modelTemp.Dispose();
}

//389
}

#region commented

#endregion

Size maxSize = new Size(1000, 1000);

Bitmap bitmap = ImageExporter.CreateAutoSizedBitmap(DestinationModel, Matrix4D.Identity,
GraphicsConfig.BlackBackgroundCorrectForBackColor,
SmoothingMode.HighQuality,
maxSize);

DwgWriter.Write("I:\\Sheet40.dwg", DestinationModel);
}

}
catch (Exception)

Hi,

You'll have to purchase a support ticket for me to look into this.

Hi,

Can you please supply the DWG and PNG files that the program references?

please find attachments


1) Original drawing file is "DRWNG-7400-ENGG-SP-7S-00005.dwg"

2) Template file "Template.dwg"

3) Image file is "qr.jpg"


Process

a. Insert template into original drawing

b.There is a block name called "Details " and it has an attribute name "Sign"

c.What we are try to achieve is insert image(qr) in to an attribute

Hi,

The program created 1 insert and added that to multiple layouts, this is invalid. Below is the corrected program (tested OK).

C# Code:
using System;
using System.Collections.Generic;
using System.Drawing;
using System.Drawing.Drawing2D;
using System.IO;

using WW.Cad.Base;
using WW.Cad.Drawing;
