For example, I have a 100*100
size imageview or button, and I want to set its image or backgroundImage
with a local .png
file. Based on my understanding, I need to create 3 sets of images, i.e. 100*100
for @1x
, 200*200
for @2x
, 300*300
for @3x
. I am not sure if my understanding is correct or not, can anyone help?
According to my understanding, if the image size is 100 * 100
@1x -> 100 * 100
@2x -> 200 * 200
@3x -> 300 * 300
There is something to understand. By creating 2x
and 3x
images, you can't expect exact same layout from each iPhone screen. The layout will be different from screen to screen. 1x, 2x and 3x image sizes dealing with only the pixel density of the screen.
Suppose you have an image which is 320 * 70
and you are creating
@1x -> 320 * 70
@2x -> 640 * 140
@3x -> 960 * 210
