Hello,

I am working on a .NET project and i have some tasks to perform from a DWG file.

First, i have to do an export to a png file in a 1920*1080 resolution.

Code: Select all

this._imageCAD = CADImage.CreateImageByExtension(pathToFile);
this._imageCAD.LoadFromFile(pathToFile);

DRect rect = new DRect();
rect.Height = 1080;
rect.Width = 1920;
   
this._imageCAD.SaveToFile("FondPlan.png", ImageFormat.Png, rect);

1/ This code works well for the png generation. But the generated file have a 1780*1080 resolution. I understand the function keeps the proportion, but can i fix it anyway with some white margin ?

2/ Then, i have to put some controls on my png file. So, i take the coordinates from my converter object.

Code: Select all

this._imageCAD.Converter.Entities

And i use the Box object, with the properties Top and Left.

Do you have some advices on how to do the transformation of the coordinate from a DWG file to PNG file ?

I already perform some transformation, but it's pretty hard to explain here, and maybe some functions do the work in the CAD import.

Thank you !

Hello.
You're correct, the resulting PNG image sizes corrected within SaveToFile method to keep the proportion. The method doesn't allow expand the output raster image by filling an additional parts.
CADImage.Converter.Entities represents a collection of entities of imported drawing. Box, Top and Left properties of an Entities member contains coordinates of this entity on drawing. CAD Import .NET doesn't provide a method for coordinates transformation between a drawing and the output raster image. However there is the CADImage.GetPoint method that transforms drawing coordinates to screen coordinates.
