Rotate image

robleer

Hi,

When you have a Picture attribute and use this on a mobile phone, you can directly take a picture.
But when you take a picture holding your Phone vertically, the image is stored rotated 90 degrees in the BO attribute.
This can happen, but when a user makes a mistake, there should be some kind of action 'rotate left/right'.
Otherwise there is (as far as I know) no way to correct this. Anybody who has a trick to rotate images which are stored in an BO attribute??
Btw: I tried it on an Android Phone only.

TIA
Rob

Rob, there are some products out there, that can be used on server side with command line in silent mode that can rotate an "image file". But the problem is that, the images that are stored in DB need to be exported to an image file first, rotated and then re-imported back to DB, all in an Aware process.
I can't find any command in Aware that I can use in Process to tell it to export an image (we must provide path and name to store on server) and then another command to import it back into the same attribute for DB.
Without these two automated commands, I don't see how we can offer this feature of rotation.

Another option is that, Aware to give us Client side Image editing using JS functionality and allows us to save it back to DB.

@Support;
Is there command to import/export images into DB from Process? If not, can we request such commands?
Thanks!

I am not Support, but I believe IMPORT DOCUMENT and EXPORT DOCUMENT can handle images.

Bob, I checked. I created a "Picture" attribute and then created a "Document" attribute to link it to the "Picture" attribute, but it didn't show in the dropdown as the attribute to pick. Unless there is another way to connect the "Picture" attribute.

Try EXPORT DOCUMENT Bo.Picture i.e. try exporting the image via the EXPORT DOCUMENT function.

Hello, I got it working.

This is the example how I did it from an Aware proces:

EXPORT DOCUMENT ShipPicture.Pic350px TO FILE 'c:\temp\plaatje.jpg'
EXECUTE PROGRAM 'c:\ImageMagick\magick.exe c:\temp\plaatje.jpg -rotate 90 c:\temp\plaatjerot90.jpg'
IMPORT DOCUMENT ShipPicture.Pic350px FROM 'c:\temp\plaatjerot90.jpg'

NOTE: You have to install ImageMagick first or something simular.
On my Windows laptop the EXECUTE PROGRAM did not work in the first place. The problem was that the user, which executes the ImageMagick program is the user where Aware runs under. This user has nog rights to write a file. You get no error message, no log, nothing... It simply does not work.
In my case I just added the Write privileges to the user and then it works. In a production environment you have to give these rights to the Windows user where your Aware service runs under because this user fires the magick.exe.

Great Rob;
So, you didn't need to add a new "Document type" attribute to your object? You simply used EXPORT & IMPORT DOCUMENT against the picture attribute in your object?
Note: on production, you need to create a special folder that is specific to that user who is doing the conversion. So, in multi user environment, two (or more )users aren't writing to the same folder with the same image name. Or prefix the image name with User ID to make it unique.

Hi Ben, no I did not specify a document type in my test process. It worked exactly as described for JPG images

I agree to you other remarks and will keep that in mind when installing it on a server environment

robleer

Oh Ben,

It was just a test, in the real application I would give the image an unique ID generated by the process to keep things apart

Bye Rob

I ran against some other problems and want to share the solution here.

If you use a tool like ImageMagick for this, you sometimes need to pass extra parameters. But, these parameters has to be quoted with double quotes. Other quotes are not working.
I've read somewhere on this forum a solution for this. Make an Attribute in the SystemSettings BO and store a double quote there. Then use this attribute in your EXECUTE PROGRAM statement. This works and I'm now able to use imagemagick for all kind of image processing things (watermarking, rotating, flipping a.s.o.)

Bye,

Rob

Thanks for the update, Rob!
