DPI issue in pdf to image conversion

while changing the dpi 5, 50, and 800 we are not able to see any difference in the image. while changing the width and height. Aspose image automatically increasing their dpi based on increasing width?. as per the conversion, if we are increasing dpi, width and height also should have to increase automatically based on dpi. The same should apply for setting width and height, it will automatically changes DPI.???
