　　PS中何时勾选、取消图像重新采样？在用PS处理图片时，很多人不知道何时勾选或取消图像中的重新采样，这两者有什么区别呢？下面，小编就为大家介绍下PS中勾选、取消图像重新采样方法。

　　勾选重新采样：网页

　　打开Photoshop软件，导入图片，点击菜单栏的图像——图像大小，

　　弹出对话框，我们可以看到重新采样选项，默认为勾选状态，而且图片大小也是以像素为单位，

　　网页分辨率就是72，在网页模式下调整分辨率用处不大，我们在这里主要调节的是图片大小，调整尺寸时、为了防止图片发生形变，一定要将前面的链接符号选中，锁定纵横比，等比例整体调整图片大小，

　　不勾选重新采样：打印

　　去掉重新采样，其中的单位像素就会自动转为厘米，打开单位下拉菜单，你会发现，在打印模式下、像素单位变成灰色，无法选中。

　　这样在你无法记清时，也可以理解为：能选中像素的情况下为网页，不能选中像素单位时为打印。

　　然后调整分辨率，一般打印的最低标准就是300ppi，调整分辨率时、其对应的宽高也会发生改变，如图所示。

　　所以，在打印图片时一般都要将其转为300ppi，看图片是否清晰，不然图片可能会出现失真。

　　以上就是小编为大家介绍的PS中勾选、取消图像重新采样方法。更多相关教程敬请关注系统之家。
