I have a cpt image that has a single object with transparency applied as a gradient from 100 to 0 via the interactive transparency tool. I would like to export this as a transparent png for web use. However, photopaint x4 doesn't seem to allow me to do this - I get a message that object(s) will be merged, and then no option to maintain the transparency.
My workaround is to save it as a psd from photopaint, open in photoshop, and then use photoshop's export for the web. But there must be a direct way to do it in x4, right?
Hello. I too was frustrated about saving real transparency for PNGs in PP. I found solution myself and didn't noticed anyone explained same tehnique in this topic. This requires no other software but Corel Photo Paint itself. I'll try to demonstrate step-by-step (in my example i use PP X3):
(The object is zoomed by 200%)
Now you can see a mask on background. That's exactly what we need
Here is result - a PNG with pure transparency achived by this tehnique
And wrong result made by PP
Here is a test showing correct transparency (achived by this tehnique) and wrong one (which is generated by PP) by placing image on various backgrounds.

Is it the same solution below (by Gadget)?
Gadget said:If you want "proper" PNG's with proper alpha channel masks within PP, then you have to maintain the original object at 100% opacity (or at least have it look this way at time of export) and use the mask as a proper alpha channel. (I would duplicate the object, hide the original, get the transparency you want, then create a mask from the object, show the origional and then export.)
Repeated with illustration:
Ahmad Ajlouny said:As Gadget deduced, the problem is that PHOTO-PAINT merges the transparent objects with a white background and then apply transparencies as alpha channel to the merged-with-white PNG. PHOTO-PAINT doesn't even respect the color set for Background Color; always merge with white.
However, we use more complex alphas and Corel PHOTO-PAINT is frustrating.
