0.99.7: DPI change is not correct

Post by Mapaler »

0.99.7
win10 64bit

Found in the process of making ID photos.
  • Photo size and DPI are not read correctly

  • If I calculate DPI 72, the automatically calculated size is completely different from the original image size

  • Then I crop and change the print size (Use the automatically calculated DPI)
    1647941997438_xnviewmp.png
  • Got the wrong DPI and print size

  • If I specify DPI and print size, the automatically calculated pixel dimensions of the resampled image are also incorrect

The first problem, when resized, can not automatically read the size and DPI

The Second
I've cropped it to the ID pic ratio 7:9

Change to the required print size 35mm x 45mm. Uncheck resample, and only change Width, The Resolution will then be calculated automatically.

Clicking back on it found that it was different from my previous set number.

If 'Load default values' is not checked, previous one are used
