transparency not working in layers

[BlueButterfly]

problem is i take the image into paint I wand and cut out background but when I go to layer the the no background image to a different background the image I have saved with no background once again has white background not transparent as saved so it will not layer to new background. I have made no background images many times over I have also transferred them to other backgrounds when using older versions of paint dot net but now can not do with newest version. any suggestions   ?

It is difficult to understand exactly what you are doing from the description but you seem to be saying you are saving the image at some point.

 

If so: what format are you using to save the image - JPG? If so that is likely the problem. Save as PNG instead.

Welcome @BlueButterfly  Are you saving the cut-out image as a .png?  That file format preserves transparency.

For some reason if you save the PNG with as 24bit you can loose transparency in Paint.NET 4.1.6

 

Just to be safe first save as a PDN then save as a TIF. you can convert a TIF to PNG later.

I always save as PDN and then a TIF I only use PNG or JPEG if it being used on the web or if it is requested.

There's neither bug nor mystery here. 24-bits is 8-bits per component, and the components are red, green, blue. 32-bits is also 8-bits per component and adds alpha.

 

Alpha is transparency.
