XDP removing PNG transparency when I open/edit/save direct. How to keep transparency?

Hi,

I'd appreciate help.
I'm using XDP feature "photo editing", in which I can open a file, edit it, and XDP saves the original as a .xar file under the folder "masters" (snapshot below).
However, when I perform this process using a PNG file with transparency, after saving the file XDP removes the transparency.
I also record my screen showing the issue: https://goo.gl/aWgXsB
How to keep transparency after saving the file?

Thanks!

The transparency should not be lost. I export directly from Xara as PNG - True Color + Alpha. I have not enabled the Master's option but I think that keeps the original image and not the modified image in case you need the original (Master) image.

The transparency should not be lost. I export directly from Xara as PNG - True Color + Alpha.

When I export, the PNG transparency is applied properly. However, the transparency isn't applied by XDP output when I edit the original, as I expected.

I have not enabled the Master's option but I think that keeps the original image and not the modified image in case you need the original (Master) image.

If set "preserve original" + "as a .xar file with the edits", when you open PNG (c:\Image.png), edit and save it, the original is replaced automatically by the Xara editing. The original is moved/embed to a .xar file (c:\Masters\Image.xar).
This feature is very handy to start editing from an already existing image (png, jpg) and XDP cares of creating the .xar file and update the original file with the editing automatically.
I'm using this process for applying images on video. The video editing software (VEGAS Pro) creates the snapshot (PNG) in the timeline, then I just open that file from the timeline, edit and save, and XDP automatically update the file in the timeline. I don't need to concern creating a .xar file, export .png and then add the file into the other software timeline. Everything happens under the hood. The integration (video-image editing) would be perfect if it wasn't the inconvenience I'm facing when the PNG has transparency, since XDP automatic output is generated without alpha (no transparency).

I'm not sure how Xara handles saving .png files in this situation but I can imagine that a registry setting may address this issue.

you have probably not told the program to save it with transparency

open a new blank photo - create an image with transparency - and click the save button - you should see this dialog box:




click on the button 'settings' and you should see this box appear




make sure colour depth is set to true colour + alpha as shown and click apply

you can now click the save button on the first box and it should save with alpha [transparency] and continue to do this for the rest of your session...

EDIT: if you need to make this setting on an existing photo - choose save as [from the file menu] instead of the save button - you can choose the same file name and say ok to overwriting [assuming you are using default 96dpi otherwise you would need to set that as well as the colour depth, using the bitmap size tab on the second screen shot above] - once that's done you should be ok for the rest of the session with that photo just by clicking save as normal

Handrawn, what the OP is trying to achieve requires another routine than you describe. See the screenshot in his first post.
