Aspose.cad java 25.10 将 DWG 转换为 SVG 出现文字、图片丢失及渲染异常问题

我的转换代码参数设置大概如下：

        File outputFile = new File(outputFilePath);
        try {
            LoadOptions opts = new LoadOptions();
            opts.setSpecifiedEncoding(CodePages.SimpChinese);
            final CadImage cadImage = (CadImage)Image.load(inputFilePath, opts);
            try {
                cadImage.updateSize();
                //cadImage.setDefaultFont("simsun");

                // 记录 CAD 文件信息，帮助诊断
                logger.info("CAD 文件信息 - 宽度: {}, 高度: {}, 单位类型: {}, 布局数: {}",
                    cadImage.getWidth(), cadImage.getHeight(),
                    cadImage.getUnitType(), cadImage.getLayouts().size());

                RasterizationQuality rasterizationQuality = new RasterizationQuality();
                rasterizationQuality.setArc(RasterizationQualityValue.High);
                rasterizationQuality.setHatch(RasterizationQualityValue.High);
                rasterizationQuality.setText(RasterizationQualityValue.High);
                rasterizationQuality.setOle(RasterizationQualityValue.High);
                rasterizationQuality.setObjectsPrecision(RasterizationQualityValue.High);
                rasterizationQuality.setTextThicknessNormalization(true);
                CadRasterizationOptions cadRasterizationOptions = new CadRasterizationOptions();

                cadRasterizationOptions.setPageWidth(cadImage.getWidth());
                cadRasterizationOptions.setPageHeight(cadImage.getHeight());
                cadRasterizationOptions.setBackgroundColor(Color.fromArgb(33,40,48));
                // 暂时只输出 Model，排除 Layout 干扰
                cadRasterizationOptions.setLayouts(new String[]{"Model"});
                cadRasterizationOptions.setExportAllLayoutContent(false);
//                cadRasterizationOptions.setLayouts(new String[] {"Model"});
//                Set<String> layoutNames = cadImage.getLayouts().keySet();
//                String[] allLayouts = layoutNames.toArray(new String[0]);
//                cadRasterizationOptions.setLayouts(allLayouts);
                cadRasterizationOptions.setUnitType(cadImage.getUnitType());
                cadRasterizationOptions.setAutomaticLayoutsScaling(false);
                cadRasterizationOptions.setNoScaling(false);
                cadRasterizationOptions.setQuality(rasterizationQuality);
                cadRasterizationOptions.setDrawType(CadDrawTypeMode.UseObjectColor);
                cadRasterizationOptions.setVisibilityMode(VisibilityMode.AsScreen);
                cadRasterizationOptions.setExportAllLayoutContent(true);//启用所有图层和内容的导出
                cadRasterizationOptions.setContentAsBitmap(false);  // 保持矢量格式

1、dwg文件，我只保留了会出错的部分，其他内容因为保密已删去
2、我的cad客户端为中望CAD，打开均是正常。aspose.cad 转换文件为svg 异常，有的是漏图有的是文字不显示，有的是图形异常，有的是丢失图片
