300dpi is recognized as 257dpi, resulting in an increase in print size

« on: September 08, 2025, 02:24:34 AM »

hi.mike.
300dpi is recognized as 257dpi, resulting in an increase in print size,I have to manually modify the size every time, which makes me very distressed. Is there a solution?
Especially when importing images of different sizes in bulk, modifying them is very time-consuming and prone to errors.

Qimage reads the embedded size (if there is one) from the file. I can't see what type of image file that is. Is it JPEG, TIFF, PSD?

If 300 PPI is embedded in the file, Qimage will use that if you select "Original Size" as the print size. If not, either the file is incompatible with embedded size reading or there is no size embedded.

You can put a sample on Google Drive and provide a link if you want me to look at your specific file to see if I can tell why it is showing that 257 PPI.

Regards,
Mike

Thank you, Mike. I have sent the sample file to your email.

I received the four JPEG images you sent. All four come up 300 DPI for me.

Are you sure you didn't override the embedded size? Click "More" at the bottom of the print sizes and then check "Original Size" and see if the override box in the upper right is checked. That's the only way I can see that you wouldn't get the embedded size when you choose the "Original Size" print size.

Regards,
Mike
