The code sample below shows the auto-scaling option in use.
Or disable automatic scaling with the ScaleType.None option. #Autocad printing as raster pddf pdf#
If the CAD drawing dimensions are smaller than the resultant canvas size, set the CadRasterizationOptions.ScaleMethod property to ScaleType.GrowToFit in order to increase the drawing size to fit into the PDF canvas while preserving the aspect ratio. If the CAD drawing dimensions are greater than the resultant canvas size, then the drawing dimensions are reduced to fit into the resultant canvas while preserving the aspect ratio. This property defines the following behavior: By default CadRasterizationOptions.ScaleMethod is set to ScaleType.ShrinkToFit mode. Use this option to automatically adjust the image dimensions according to the CadRasterizationOptions.PageWidth and CadRasterizationOptions.PageHeight values. The scaling options are set by the CadRasterizationOptions.ScaleMethod property. Set the CadRasterizationOptions.PageWidth and CadRasterizationOptions.PageHeight properties explicitly, or you may get an ImageSaveException.Īdditionally, you may specify dimension scale options. Since the resultant PDF or image requires the canvas size to be defined, we need to specify the output dimensions for the PDF page to render the drawing properly. Specifies if auto-layout scaling has to be performed to match the Model layout.Įxport from CAD to PDF or CAD to raster image formats is not a trivial task. 
Specifies the overridden entity’s color (only if DrawType is set to the UseDrawColor property value). Specify the UseObjectColor option to draw entities using their native color, or the UseDrawColor option to over-ride native colors. Specifies the entity’s colorization mode. Specifies the output image’s background color. Switch to GrowToFit mode, or use the None setting to disable automatic scaling. The default value automatically shrinks the image to fit the canvas size. Specifies whether the drawing should be automatically scaled. The most useful CadRasterizationOptions class properties are: Property The CadRasterizationOptions class is common for all supported CAD formats such as DWG & DXF therefore, the information shared in this article is valid for both aforesaid CAD formats. The CAD to PDF & CAD to raster image conversion procedures are highly configurable because the CadRasterizationOptions class has been implemented in such a way that it provides many optional features that upon setting can override the rendering process according to the application needs. However, you may also specify the layouts of your choice while converting CAD drawings to image formats.
Call Image.Save by passing the file path (or an object of MemoryStream) as well as the instance of ImageOptionsBase created in the previous step.īy default, the API renders only the “Model” layout. Create an instance of ImageOptionsBase and set its VectorRasterizationOptions property to the instance of CadRasterizationOptions created in the previous step. Create an instance of CadRasterizationOptions and set its mandatory properties such as PageWidth & PageHeight. Load the CAD file into an instance of Image. You can convert any supported CAD drawing format to raster image formats using the simple steps as elaborated below. NET API has exposed efficient & easy to use means to achieve this goal. NET is capable of converting CAD drawing formats such as DXF & DWG to the supported raster image formats such as PNG, BMP, TIFF, JPEG & GIF. Converting CAD Drawings to Raster Image FormatsĪspose.CAD for. NET to change or remove this information from output Documents. Please note that you cannot instruct Aspose.CAD for. NET populates Application field with value ‘Aspose.CAD’ and PDF Producer field with a value, e.g ‘Aspose.CAD v 17.9’. For example, upon rendering Document to PDF, Aspose.CAD for. NET directly writes the information about API and Version Number in output documents.
