Generating pictures from DXF Files
Below is a sample C# code snippet that demonstrates how to generate bitmap images from DXF files using the DXFReaderNET library. This code provides a simple and effective way to convert DXF files into bitmap images, enabling you to visualize and work with CAD data in a rasterized format:
DXFReaderNETControl _dxfControl;
_dxfControl = new DXFReaderNETControl();
_dxfControl.ReadDXF(dxfReaderNETControl1.FileName);
_dxfControl.Width = 2000;
_dxfControl.Height = 2000;
_dxfControl.AntiAlias = false;
_dxfControl.ShowAxes = false;
_dxfControl.ShowGrid = false;
_dxfControl.BackColor = System.Drawing.Color.White;
_dxfControl.ForeColor = System.Drawing.Color.Black;
_dxfControl.ZoomCenter();
pictureBox1.Image = _dxfControl.Image;
_dxfControl.Dispose();
Here's a breakdown of each line:
-
DXFReaderNETControl _dxfControl;: Declares a variable _dxfControl of type DXFReaderNETControl, which is a control provided by the DXFReaderNET library.
-
_dxfControl = new DXFReaderNETControl();: Instantiates a new instance of the DXFReaderNETControl control and assigns it to the _dxfControl variable.
-
_dxfControl.ReadDXF(dxfReaderNETControl1.FileName);: Reads the contents of a DXF file specified by dxfReaderNETControl1.FileName and parses it using the _dxfControl instance.
-
_dxfControl.Width = 2000;: Sets the width of the _dxfControl control to 2000 pixels.
-
_dxfControl.Height = 2000;: Sets the height of the _dxfControl control to 2000 pixels.
-
_dxfControl.AntiAlias = false;: Disables anti-aliasing for rendering, which can improve performance but may result in less smooth graphics.
-
_dxfControl.ShowAxes = false;: Hides the display of axes (coordinate system) in the _dxfControl control.
-
_dxfControl.ShowGrid = false;: Hides the display of the grid in the _dxfControl control.
-
_dxfControl.BackColor = System.Drawing.Color.White;: Sets the background color of the _dxfControl control to white.
-
_dxfControl.ForeColor = System.Drawing.Color.Black;: Sets the foreground color (e.g., line color, text color) of the _dxfControl control to black.
-
_dxfControl.ZoomCenter();: Zooms the view of the DXF drawing to center it within the _dxfControl control.
-
pictureBox1.Image = _dxfControl.Image;: Assigns the image representation of the DXF drawing within the _dxfControl control to a PictureBox (pictureBox1 in this case) for display.
-
_dxfControl.Dispose();: Disposes of the _dxfControl instance, releasing any resources it holds.
This code snippet demonstrates how to use the DXFReaderNETControl to load and display a DXF file within a C# application's PictureBox. The control provides various properties and methods to configure the display settings and interact with the DXF drawing.
