About the issue of ImageCropper missing a pixel from a cropped image

### Describe the bug

When I used ImageCropper to cut the image,

the computer resolution was about 2K, and the image size was 128x296.

If I select the button method to reduce the area and then select all the pictures for cutting and saving,

there will be a loss of one pixel,

the size of the picture will become 127x295,

this time it will affect the image when I convert the picture to a fixed resolution,

and then affect the display,

I have seen the source code, the source code part will lose some data when there is a rounding,

so I want you to see if there is any solution to solve this problem.


The compressed package is a test image.

### Expected behavior

I want to cut the image if the length and width of the picture is 128:296, if I choose the original image size, please do not remove one pixel, this will affect the display of the image.
