How to detect blank area in certain area

for any image file (png,jpg,jpeg,bmp)
how to detect blank area in certain area?.. I need to make sure that the certain area must be blank…
please help



I have observed your requirements and like to share that you need to traverse the pixel by pixels to identify any certain area bearing certain RGB value can be considered as blank area. There is no other option available other than this to achieve the goal as from Aspose.Imaging perspective all pixels bear some RGB and that you need to verify.

can you provide C# example for doing this?
