Converting one of the attached files to PNG using GroupDocs Conversion 24.2, results in a very pixelated image.
AutoCAD Pixelated.zip (607.4 KB)
Even with high resolution or DPI the result is not usable:
image.png (79.5 KB)
I used that code for conversion:
using (var conv = new Conv.Converter(documentPath))
{
var imgOptions = new ImageConvertOptions()
{
Format = ImageFileType.Png,
Width = 2000
};
Func<int, Stream> getPageStream = page => new FileStream(string.Format("Conversion{0}.png", page), FileMode.Create);
conv.Convert(getPageStream, imgOptions);
}
