I'm making simple image editor by C# winform. I'm trouble with make zoom function. in other similar questions, many people simply suggest that 'change the size' such like..

Bitmap newImg = new Bitmap(oldImg, newWidth, newHeight);

But In this way, the picture become blured(is it caused by antialiasing? I don't know well...) I need pixelated zoom Image. Like any other image editor such as Photoshop or paint.net...

I tried also put pixelate function to make mosaic image. result was good but it was too slow! please help me. How can I make pixelate zoom?

Check out Image resizing in .Net with Antialiasing, this should get you started (I'm not sure but setting SmoothingMode = SmoothingMode.None means no anitaliasing).
