Android Question Same issue... Rotated camera pictures.

[tigrot]

Hi everybody,
I'm fighting with an APP saving pictures rotated by 270°( or better -90°). I have seen that Samsung smartphones seem to save portrait taken photos rotated with an exif header indicating that photo is rotated. I don't know if other phones do the same.
I save the images on a web server. Internet Explorer doesn't care about exif so images looks rotated, while Chrome and Firefox show the images correctly.
Any way to save in portrait with no rotation? The images are very large and processing can be long. I use CameraExClass V.1.20. I have seen much code, but nothing not starting from a saved image

Best regards and thank you in advance.

The camera library returns the image data exactly as it comes from the native API.

You can use the Jpeg library to check the exif headers and if needed load the bitmap, rotate it and save it again.

Thank you I'll give a try... Rotation modifies EXIF header too or I have to do manually?

Have a nice week-end.

Hi Erel
seems I'm not able to rotate the image, 'cause of a memory overflow. I'll change on server side...

I assume that the exif headers are correct. The problem is that some viewers ignore them at all.

You are correct. IEXPLORER ignores everything!
I have solved my issue on server side. The server side is a small PHP script which in turns launch JPEG Lossless Rotator. It scans a whole directory, the one I just send and automatically rotate each image according EXIF data. Quick and clean solution, which gives the best quality ever!
Thank you Erel, you always have an Hint ready for us!
