Loading all images from a folder about tev HOT 6 CLOSED

Hi there,

unless I misunderstand something, 1. should be easy to do. Via the command line, add tev to your PATH, then do tev path/to/folder/*. If you prefer using a file browser (e.g. explorer on Windows), make tev your default application for opening the type of image file you are using, then select all images in the given folder via Ctrl+A, and then press Enter. (Cmd+A; Cmd+Down on macOS.)

Your second use case is unfortunately not supported by tev. tev can only display a single image at a time.

Cheers!

Hi Tom!
Thanks for the prompt reply :)
I meant amending the code and the nanoGUI components directly and not via the command line (though its is nice that it is possible).

Something like this QT example:

Oh, I see! I think the easiest route would be to create 2 ImageCanvas widgets side-by-side (instead of having a single one like right now) and have ImageViewer set the image and display settings of both accordingly.

A slightly more direct (and hacky) approach would be to bake the normalized image and the original image into a larger image (with twice the width) within the respective image loading routines in Image.cpp.

Hope this helps! :)

Yes, it does. Thanks.
Any idea why loading a single JPG would take so long on a very strong computer?

Also, more than 3/4 of my images fail to load with this error:

Do I need to covert some of them to another format?
Many thanks!

Also, if I select 50 images (CTRL A), and the selct an Image it allways ends like this:

Unfortunately I do not know why loading takes long on your end. Since LDR images (including jpegs) are not the primary focus of tev the loading routine is delegated to a not necessarily fast third-party implementation (this one). This is likely also the source of incompatibility with some of your images and sadly not something that I can easily fix at my end. Basically, the most practical option I see would be to add an additional image-loading backend in Image.cpp, which makes use of a specialized jpeg loader.

Regarding your crash: Are you perhaps running out of memory? tev is loading every single image into RAM in uncompressed form, so if your images are large it can quickly become too much.
