Save file

[roman]

Hello,

is there a possibility to save a drawing (opened from a jpg / including some drawing).

When i try to save the image i only can save it as raster image (dxf doesn't work).

I need to save the image so I can open it later and contiue to work on it / also the handles of the entities should'nt be changed.

thank you,
Roman

Hello Roman.
JPG image consists of a set of pixels. CAD Import .NET allows to save JPG or other raster image as DXF, but such DXF will contain Image entity only. It will not contain other entities.

In the editor Demo is the possibility to serialize the objects and save as .dat binary file.
This doesn't work in the demo!

Seialization works if only Drawing objects are serialized (if an Imageentity is added there's an error...)
Deserialization always throws the following Error: "Object of type 'System.Int32' cannot be converted to type 'System.Byte'." (Stacktrace below)

How can this be fixed?

Hello Roman.
Unfortunately serialization/deserialization feature doesn't stable enough within current CAD Import .NET version. We're not recommend to use it until it is updated. We're working on this problem.

Hello,

is there a timeline when this will be fixed?

Thank you.

Hello Roman.
Unfortunately we can't provide any timeline for the issue, sorry.

Hello,

do you have a soliution for the serialization / deserialization issue?

Thank you
Roman

Hello Roman.
Unfortunately the solution doesn't ready. The issue requires more effots from us than we expected earlier so we suspend it currently. We're working intensively on DWG export feature instead. It planned for release with library version 9.1.

Is there any improvement in Deserialization?

[support]

Hello Vijay

Our developers came to a conclusion that it would be impossible to improve the serialization/deserialization with the current configuration of CAD .NET. The work to enhance serialization/deserialization was suspended and there are no plans to restart it in the near future.
