I just wonder about the pixel size in bitmap, if it is already defined or variable.
if one squre bitmap with width and height are 10 mm, and each side has 10 pixels, so there are 100 pixels in this squre ( 10 x 10)
so each pixel has 1mm long width and height.
but if I increase this squre bitmap twice larger, e.g width and height are 20mm. so, how about pixel size then?
they are 2mm for each?
I hope you can understand my question
