Aspose.CAD for Python via .NET专门用于处理 CAD 图纸。它的安装过程非常简单。只需联系慧都科技下载SDK 文件或在 CMD 中运行以下命令pip install aspose-cad使用 Python 将 SVG 转换为 PNG - 代码示例除了转换功能外这款强大的 SDK 还允许您选择特定图层并跟踪转换过程。现在让我们开始查看代码步骤和代码示例。步骤通过调用load方法从给定的输入路径加载 SVG 文件。配置光栅化选项以将矢量转换为光栅。设置输出图像的宽度、高度和缩放级别。创建PngOptions类的对象。使用配置的光栅化将加载的 CAD 图像保存为 PNG。使用下面给出的代码片段在 Python 中将 SVG 更改为 PNGimport aspose.cad as cad from aspose.cad.imageoptions import PngOptions # A class to handle CAD image conversion using Aspose.CAD for Python via .NET class CadImageConverter: def __init__(self, input_path, output_path, license_path): # Store input, output, and license file paths self.input_path input_path self.output_path output_path self.license_path license_path self.image None self.raster_options None def apply_license(self): # Apply the Aspose.CAD license to unlock full functionality print(Applying Aspose.CAD license...) license_obj cad.License() license_obj.set_license(self.license_path) print(License applied successfully.) def load_cad_image(self): # Load a CAD (or SVG) file from the given input path print(fLoading CAD image froms: {self.input_path}) self.image cad.Image.load(self.input_path) print(Image loaded successfully.) def configure_rasterization(self, width800.5, height800.5, zoom0.5, layersLayer): # Configure rasterization options for converting vector to raster print(Configuring rasterization options...) self.raster_options cad.imageoptions.CadRasterizationOptions() # Set output image width self.raster_options.page_width width # Set output image height self.raster_options.page_height height # Define zoom level self.raster_options.zoom zoom # Specify which layers to render self.raster_options.layers layers print(Rasterization configured.) def save_as_png(self): # Save the loaded CAD image as a PNG using the configured rasterization print(fSaving image as PNG to: {self.output_path}) png_options PngOptions() png_options.vector_rasterization_options self.raster_options self.image.save(self.output_path, png_options) print(Image saved as PNG successfully.) def main(): input_svg sample1.svg output_png result-file.png license_file license.lic # Initialize converter with file paths converter CadImageConverter(input_svg, output_png, license_file) # Apply license, load the image, configure rasterization, and save as PNG converter.apply_license() converter.load_cad_image() converter.configure_rasterization() converter.save_as_png() # Run the script if executed directly. if __name__ __main__: main()输出
