#32282 new defect (bug)

WordPress image cropping is buggy

Reported by: Jossnaz Owned by:
Milestone: Future Release Priority: normal
Severity: normal Version: 4.2.2
Component: Media Keywords: has-patch
Focuses: administration Cc:

text copied from there:

This is the wordpress version 4.2.2 powell

I crop 1500 x 1000 and then press on crop, then save.

Resulting image size:

1497 x 1000

I don't know, I somehow hoped that wordpress is able to crop correctly.

The original image can be found here:


What I did is downsize to .... x 1000 then try to crop with selection manually entering 1500 x 1000

You can actually see the bug earlier, when you enter 1500 x 1000 and then click on the selection to drag it around (right, drag the selection, not change size) it results in the number 1500 falling down to 1498.

I successfully reproduced this bug using the latest trunk from 4.5 and the provided image. After manually setting a crop size of 1500x1000 the image size then changed to 1497x998 once I pressed the crop button, or tried to move the selection area.

  • Crop the image in 100% scale to avoid rounding errors.
  • Don't recompute selection values when selection is dragged only.
  • Fix the issue where the selection values are off after the image is scaled down or restored.
  • Keep aspect ratio when holding the shift key.
