Description Me 2009-09-30 17:26:10 UTC
Version:            (using KDE 4.3.1)
Installed from:    Fedora RPMs

This concerns Album View -> Batch -> Resize Images.  I saw this because I am not sure what resize tool is used in the Light Table part of digikam. 

It would be really nice if there was an option when resizing the image to keep the aspect ratio of the original image when changing the size of one of the axes.  

For example, lets say my camera is 2:3 and produces jpgs of 800x1200.  When I use the resize tool, it would be nice if I could lock the aspect ratio (at 2:3) and then change X to 600 and have Y change to 900 automatically.  Or I could slide Y to 1800 and X could change to 1200 automatically. 

As it is right now, I have to get my calculator out everytime I resize images to keep the aspect ratio correct.

BTW: I really like how the resize tool is implemented in GIMP.  I know that the digikam resize tool needs to be a bit different because its a batch tool, but you might want to look at the GIMP resize tool for ideas. 

Thanks for listening.

The impetus for this change came from a limitation in the raw converter ie no --shrink or --size options.  See bug (wish) #209000.

I checked out the resize tool in the Edit window and it has an aspect ratio lock. 

I understand that it might be difficult to lock the aspect ratio of a group of images in batch mode because they might not all be the same size.  However, it is just as hard to lock down the actual size of a bunch of images when they aren't the same aspect ratio or not even the same orientation.

I feel the batch resize tool needs some work in this respect as it would be very helpful to be able to convert images of differing aspect ratios and orientations to one size (in one dimension) and keep the aspect ratio.

This file still valid using kipi-plugins 2.4 ?

I don't seem to remember what I was refering to at the moment ... It might have been related with resizing a batch of pictures of different formats in order to upload them to my Piwigo gallery, but the Piwigo export plugin has been developed since then and it does the trick with no glitch.
