问题描述
例如，我有 100 * 100 尺寸的图像视图或按钮，我想设置其图像或 backgroundImage 使用本地 .png 文件。根据我的理解，我需要创建3组图像，即 100 * 100 @ 1x ， 200 * 200 @ 2x ， 300 * 300 @ 3×。我不确定我的理解是否正确，任何人都可以帮忙吗？
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?
推荐答案
根据我的理解，如果图像尺寸 100 * 100
According to my understanding, if the image size is 100 * 100
@ 1x - > 100 * 100
@ 2x - > 200 * 200
@ 3x - > 300 * 300
有一些东西可以理解。通过创建 2x 和 3x 图像，您无法期望每个iPhone屏幕都具有完全相同的布局。屏幕与屏幕的布局不同。 1x，2x和3x图像尺寸仅处理屏幕的像素密度。
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.
假设您的图像 320 * 70 并且您正在创建
Suppose you have an image which is 320 * 70 and you are creating
@ 1x - > 320 * 70
@ 2x - > 640 * 140
@ 3x - > 960 * 210
这将是您在不同屏幕上的输出。
This will be your output in different screens.
