Hi All,
Has anyone else come across it, that when viewing photos from the back camera on the xperia 10iii, the 4000x3000 pixel images get cropped from 4:3 down to 1:1.
This happens if the device is held as portrait or landscape, and regardless of whether the photo was taken as portrait or landscape.
Any other images that you download from the interwebs etc have no such issue in the app.
Also, images taken with the telephoto camera, which have a different resolution, are unaffected by the issue.
Sounds like there is a limit of max size. You can test this with a smaller image.
All image formats has a max size which is often much bigger than the max size for image manipulations like convert format or crop. Image manipulation happened in RAM so the free aviable RAM can be limit the size too.
You noted a difference between images from your camera and downloaded images. Please accept the a file extension like “.png” or “.jpg” is not enough to describe the quality. See Wikipedia for more details.
So much limits can be there. Your post provides not enough exact informations for an exact answer. Please search your self for the exact limits for your image.
Is this on aarch64?
I think the maximum size in Qt for a QImage is WxHxBPP which can not exceed INT_MAX which normally is 2147483647.
echo $(( 4000*3000*32 - $(getconf INT_MAX) ))
Yep, this is on a 10iii: app was downloaded from the built-in Jolla store in SFOS.
I slapped on ImgOrganizer from Storeman to supplement Sailphoto and it displays these images fine.
Normally, if an application runs out of memory while handling an image, the resize operation can’t succeed.
So it shouldn’t be able to crop it either, because it needs to load the whole image into memory to do the crop as well.
