Wmf to png conversion absolute line and divid line very faint

Using aspose.imageing java product: converting wmf to png file.
After converting wmf to png , the absolute line e.g. |u| , “|” getting very faint in png file.
wmf file and converted png file enclosed in zip format.
import_image1_18720283695400.zip (10.8 KB)

code :

try (Image image = Image.load(mfFile.getAbsolutePath()))
			        {
			            WmfRasterizationOptions rasterizationOptions = new WmfRasterizationOptions();
			            
			            
			            
			            System.out.println(" Before converting  width :"+image.getWidth()+" height : "+image.getHeight()+" size "+image.getSize());
			            
			           if(image.getWidth() > 200 || image.getHeight() > 200) {
			        	   rasterizationOptions.setPageWidth((int)(image.getWidth()));
						    rasterizationOptions.setPageHeight((int)(image.getHeight()));
			           }else {
			        	   rasterizationOptions.setPageWidth((int)(image.getWidth()*3*6));
						    rasterizationOptions.setPageHeight((int)(image.getHeight()*3*6));
			           }

					    System.out.println(" After converting  width :"+rasterizationOptions.getPageWidth()+" height : "+rasterizationOptions.getPageHeight());
					    
			            PngOptions pngOptions = new PngOptions();
			            ResolutionSetting resolutionSetting = new ResolutionSetting(300.0, 300.0);
			           pngOptions.setResolutionSettings(resolutionSetting);
			            pngOptions.setVectorRasterizationOptions(rasterizationOptions);
			            
			            image.save(pngFile.getAbsolutePath(), pngOptions);
			        }

Hello @supportmeritstudents
I am sorry for the delay.
To our sorry, we could not reproduce this issue.
Please let us know more about your environment, e.g. Operation System, Java version, and version of Aspose.Imaging you use.
Additionally, you may perform some experiments by setting the following options (since they depend on OS/Java/installed fonts and so on)

// Please test the different options here 
rasterizationOptions.setTextRenderingHint(TextRenderingHint.ClearTypeGridFit);
// and here 
rasterizationOptions.setSmoothingMode(SmoothingMode.HighSpeed);
