Saving .png with Transparent back ground

Some times back ground is white and some times it's black.

When viewing in a viewer.

Open with PDN again, it's Transparent.

What gives? :?

[Nesk]

I don't know... It happens to me too. I open it with MS Paint and the background is black, but with Pdn its transparent!

[Myrddin]

Some programs may not be able to handle the transparency of a .png. They're clearly not as superior as PDN

[Ash]

Saved 2 images, 1 is showing black back ground and the other is showing white when using viewer, in PDN both are Transparent.

If they are all white or all black I can understand..

As Myrddin said, some programs do not support transparency. Also, with being transparent, they take on the background color. Thus why if you have a blue background, the transparent will be blue.Just covering all the bases.

Look at This.

Haha...I found the way to make all of em Transparent back ground white when using viewers.

In PDN, even if the black ground showing it's Transparent, when saving as png, sometimes show white back ground and sometimes show black.

To get all of em white, just use magic wand to select all the Transparent areas and hit Delete.

Save file again.....Now all the black "Transparent" area turns to white in image viewer.

Strange....but it works. 8)

I found the problem, After using the last trick to get white Transparent black ground in png, I found out if I use Feather on the oject.. the back ground in PDN looks to be Transparent but when save as png...again the back ground trues black in viewer.

Matter of fact...changing many settings in pdn will make the Transparent back ground trun to black in viewers....

I think some how pdn is saving some info that should not be saved?? :?

So selecting the area and hit delete would get rid of that "extra" info

and works.

@XLT: I got your 1st message and it's a different issuse

Moved to Bugs & Troubleshooting

[Ash]

Thanks, I was thinking it did turned into a bug issuse :?

[Rick Brewster]

Well, it's bugs and troubleshooting. Just because there's a problem doesn't mean it's a bug

Anyway, for what you're seeing ... it depends on the viewer you're using. Some older ones don't quite "get" the alpha channel. Paint.NET does save the alpha channel correctly for PNG images.

Ok thanks

I am using Picasa2 as my viewer, in case you wanna know BTW.

I have seen both black and white at the same time for transparent images. Take today for example,

I was making some images for a mod I am doing for a video game. I made the background of the image transparent and then saved it as a .png. The background showed as black in the viewer I was using. I then re-open the image and change the canvas size from 88 x 90 to 128 x 128 as the game can only support images of that size for the part I was modding. I then deleted the white areas making them transparent on the sides and save it as a .dds file as that what the game needs. When I view the file in a viewer the sides were white and the rest of the background was black. Yet when re-open in Paint.NET the background is all transparent.

If you need better understanding of the problem I am having with my transparent images I can show you the Paint.NET view and then the viewer view tomorrow affter my 7 hours of Hardware + Troubleshooting and UNIX.

^ same thing happened to me, So I found out the select with magic wand and delete the "Transparent back ground" then in viewer will show all white back ground.

[Yata]

Have you tried Windows Picture and Fax viewer, though?

[Ash]

Works fine with Windows Picture and Fax viewer.

Thanks 8)
