FEATURE REQUEST - COLOR MANAGEMENT WHEN RESIZING IMAGES

Hi, I would like to see preservation of color profiles when resizing images for a gallery. Or option to assign a default color profile information to the resized images. Below is a conversation I've had with tech support:

    Hello.

    Unfortunately, as you have discovered, JuiceboxBuilder-Pro does not retain metadata (such as ICC color profiles) in images that have been processed (either resized or watermarked) for use in a gallery.
    In order to have metadata in gallery images, you could resize the images for your gallery in an imaging program which is able to retain metadata (such as Adobe Photoshop) prior to feeding them to JuiceboxBuilder-Pro and deselect the 'Resize Images' and 'Use Watermark' checkboxes on the 'Images' tab. JuiceboxBuilder-Pro will then just copy the images directly across to the gallery's 'images' folder (complete with any metadata that they may have embedded within them) without processing them at all.

    Incidentally, JuiceboxBuilder-Pro does not intentionally strip out the metadata. It is a side-effect of the way that images are resized. In resizing an image, a new image is created from the original image's pixels (using a suitable algorithm) and the metadata is not actually part of the process. In order to retain metadata, it would likely be necessary to extract all metadata from the source image, store it somewhere temporarily and embed it into the resized image. With all the different metadata formats available (e.g. EXIF, IPTC, XMP, ICC) and all their possible values, this is likely to be quite a complex task (and I do not know if this is even possible within an Adobe AIR application such as JuiceboxBuilder-Pro).

    I hope this at least sheds some light on what is happening. (JuiceboxBuilder-Pro does not have a specific method to remove metadata. The non-retention of metadata is simply a side-effect of processing images the way that JuiceboxBuilder-Pro does.)

    Processing images prior to using JuiceboxBuilder-Pro and instructing JuiceboxBuilder-Pro to use these images for the gallery (without any further processing) would be the best workaround at present.

    You might like to suggest your idea in the Feature Requests forum thread: https://juicebox.net/forum/viewtopic.php?id=5
    This keeps all the ideas together and ensures that they are not overlooked by the developers.
    I do not know the likelihood of any suggestions being implemented (and I do not know if it would be possible to retain ICC color profiles using Adobe AIR) but this is certainly the best place for all ideas.
    Thank you.

The images in the gallery that Juicebox builder creates seem to have no colour profile embedded - the original images are in sRGB, however in the slideshow they show up too saturated on the screen, i.e. they have no colour profile embedded. So far I have had to go and re-apply the colour profiles to each individual image in the slideshow folder, however this is cumbersome and annoying. Is there a way for the juice box software to keep the colour profile when resizing and making its copies of the images, or to save each image with an sRGB profile embedded?
