i have a naive question about image definition resolution and dimension on GIMP. 我对GIMP上的图像定义分辨率和尺寸有一个幼稚的问题。

If we take this example : 如果我们举这个例子：

1)sensor: 4000x3000 =12 000 000 pixels (image definition) resolution : 300 ppp (dpi) Image dimension will be : 3000/300 x 4000/300 = 10 x 13.3 pouces in cm : (10 x 2.54) x (13.3x2.54) = 25.4 x 33.8cm 1）传感器：4000x3000 = 12 000 000像素（图像分辨率）分辨率：300 ppp（dpi）图像尺寸将为：3000/300 x 4000/300 = 10 x 13.3厘米长（10 x 2.54）x（13.3x2 .54）= 25.4 x 33.8cm

2)sensor : 4000x3000 =12 000 000 pixels (image definition) résolution : 72 ppp (dpi) Image dimension : 3000/72 x 4000/72 = 41 x 55 pouces in cm : (41 x 2.54) x (55x2.54) = 104 x 141cm ( a bigger width and length) 2）传感器：4000x3000 = 12000000像素（图像清晰度）分辨率：72 ppp（dpi）图像尺寸：3000/72 x 4000/72 = 41 x 55厘米长（41 x 2.54）x（55x2.54） = 104 x 141cm（更大的宽度和长度）

My question is why when i test these 2 configurations on GIMP, i get 2 images of the same width and length ? 我的问题是为什么当我在GIMP上测试这两种配置时，会得到两张相同宽度和长度的图像？

By default, GIMP uses the image's size in pixels to determine how to display it - 100% zoom if the image fits the screen, zoomed out if it is larger, with the behavior adjustable to some degree in the preferences' Image window section. 默认情况下，GIMP使用图像的大小（以像素为单位）来确定显示方式-如果图像适合屏幕，则100％缩放；如果图像较大，则缩小；在首选项的“图像”窗口部分中，行为可在一定程度上进行调整。

Both of your images have the same size in pixels, so they appear as the same size when you open them in GIMP. 两个图像的像素大小相同，因此在GIMP中打开它们时，它们的大小相同。

When you want their resolution to be taken into account, you have to disable Dot for Dot display in the preferences. 如果要考虑其分辨率，则必须在首选项中禁用“ 逐点显示”。 If you have also set up your screens resolution in GIMP's Display preferences, then the image should be shown at the sizes you expect, at least at 100% zoom. 如果您还已在GIMP的“显示”偏好设置中设置了屏幕分辨率，则应以您期望的尺寸显示图像，至少以100％缩放显示。
