You can resample bitmaps in two ways: by resizing it or by changing its resolution. Resolution is the amount of detail and information an image file contains. When you work with bitmaps, resolution affects both the quality of the final output and the file size.
You can resize the bitmap using absolute or percentage values. You can resize a bitmap while maintaining its original proportions. It is best to adjust bitmap width or height separately. In fact, if you want to maintain the integrity of the bitmap, you should never increase its size.
You can change the resolution of a bitmap in one of three ways: by changing the horizontal and vertical bitmap resolution, by choosing the processing quality of the resampled bitmap, or by correcting bitmap distortion when you resample.
