Wipeout can not be readed in AutoCAD2016 about dxf HOT 5 CLOSED

Can you provide some more detail? Is the problem that AutoCAD can't open a WIPEOUT entity created with this library, or that this library can't read a WIPEOUT entity created by AutoCAD? If it's the former can you provide a code sample, and if it's the latter do you have a file you could share that I could test with? Are you using the NuGet packages or building from source?

from dxf.

I use this library by building from source myself with .net 4.0.
The code is pasted as follow:
`
static void TestWipeout()
{
string fileIn = @"E:\test1.dxf";
if (System.IO.File.Exists(fileIn))
{
System.IO.File.Delete(fileIn);
}
DxfFile dxfFile = new DxfFile();
DxfWipeout pDxfWipeout = new DxfWipeout();
pDxfWipeout.ClippingVertices.Add(new DxfPoint(-30, 30, 0));
pDxfWipeout.ClippingVertices.Add(new DxfPoint(-20, 60, 0));
pDxfWipeout.ClippingVertices.Add(new DxfPoint(10, 70, 0));
pDxfWipeout.ClippingVertices.Add(new DxfPoint(-10, 40, 0));
pDxfWipeout.ClippingVertices.Add(new DxfPoint(30, 20, 0));
pDxfWipeout.ClippingType = DxfImageClippingBoundaryType.Polygonal;
pDxfWipeout.UseClippingBoundary = true;
dxfFile.Entities.Add(pDxfWipeout);
using (FileStream fs = new FileStream(fileIn, FileMode.CreateNew))
{
dxfFile.Header.Version = DxfAcadVersion.R2013;
dxfFile.Save(fs);
}
}

    static void Main(string[] args)
    {
        TestWipeout();
    }

`
After loading the test1.dxf file into AutoCAD2016, there is nothing showed.

from dxf.

The WIPEOUT entity wholly inherits from IMAGE which requires that the .ImageDefinition property be set. Something like this should work:

using IxMilia.Dxf.Objects;
// ...
// assuming you've already set the clipping like above
pDxfWipeout.ImageDefinition = new DxfImageDefinition()
{
    FilePath = @"C:\path\to\file.jpg",
    ImageWidth = 640, // this should come from the image
    ImageHeight = 480, // this should come from the image
    PixelWidth = 1.0, // I'm not sure if this should be 0.0, 1.0, or ImageWidth
    PixelHeight = 1.0, // same concern here
};

from dxf.

If wipeout needs the Imagine definition set - what about requiring that to be passed into the constructor? I could make the change and put in a pull request?

from dxf.

I recently (~13 days ago) made DxfImage easier to instantiate correctly in commit a48cba6 so I just now in commit 49151a1 added a similar constructor to DxfWipeout.

I don't have a copy of AutoCAD to test with, but both QCAD and the Teigha Viewer from the Open Design Alliance can display an IMAGE entity created with this library now (which means they should handle WIPEOUT, too, since they're identical.)
