i convert jpeg with exif information to 80% quality.
the result is very good but the exif information are lossing in thsi process.
the checkbox to "keep exif... is checked.
Can you provide me the original image you converted?
You seem to have CSS turned off.
Please don't fill out this field.
yes no problem
second test, because the first has after upload no exif
now. original and compressed image in a rar-file
I'm going to check the reason why EXIFs information are lost.
Just done some test using the 1.4.1 portable version and with a fresh 1.4.1 installation.
With the settings you provided me, my compressed image keeps all the EXIF information in the right way.
Can you provide me more details like:
- Original folder path
- Compression folder path
- Which boxes are checked in the "Tools -> Settings -> Compression" tab along with "Keep EXIF info..."
Did you try to compress other pictures taken with the same camera with the same options and check if EXIF is correctly copied?
hmmm... here are the informations
original folder: \nas\Qmultimedia\Picture\Events\2011.Daenemark
compress folder is the same
if the image on the same machine, the exif is removed too.
the attached file is the result after compression
settings from the program
first test: test with the portable 1.4.1 and install version
second test: with two camera fotos (Fujifilm FinePix AX250 and Panasonic FZ200)
result: exif was removed
OS: win 7 Ultimate 64 bit
OS: Win 8 32 bit
Version: Caesium portable 1.4.1
Result: The image has no exif information after compressed
I compressed over 400 photos with with exif infos (two different cameras).
But in all the compressed images were no EXIF information available.
Four test with two other programms: XN-Convert (http://www.xnconvert.com) and IrfanView
Both programs keep the exif info.
i searched in the scr the codeline which copy the exif informations.
I run this line:
"tools\exif_copy.exe \"" + t_list.at(i) + "\" \"" + t_dir + "\" + info.completeBaseName() + t_suffix +"\"";"
manuell in the cmd.
The result is: Exif information was copied to the new picture.
But it work not about caesium.
Thanks for all the info you provided. I'm going to run some more tests these days to address the iussue. I will update you when I'll have some news.
In all my tests Caesium seems to work as intented. Quick hint: be sure to run Caesium as Administrator or the programm may not use the external .exe to copy EXIF.
I've tried to launch the tool (from v1.4 to v1.7) as an administrator as well as on x64 and x32 Windows. So, I have to confirm that all the EXIF information is vanished after compressing in any cases.
