This is a bit of a noob question, but:

I create a 256x256 image in Paint Shop Pro 7.02 with some parts of the image transparent. I save the file in PNG format. When I try to use the icon in ObjectDock or open the PNG in PSP again, the transparent parts have become white (#000000). How do I make these parts stay transparent?

I appreciate any help I can get I've taken so much from this site and I'm trying to give back a little. Thanks!

Are you creating the image on a transparent background? Are you using anti-aliasing? Also perhaps you should use the Export to png function to confirm that the image transparency is being saved properly.

That's how I retain transparency on png images.

I actually had that exact problem with PSP 7.02. It is an error in that version. You need to upgrade to 7.04.

ah... doesn't 7 upgrade to 8?

I had forgotten about that quirk Chas........ haven't used 7 in so long.

Joe.. yes, but what Chas really means is he needs to install the maintenance update patch for 7.04.

Usually nowadays, software like PSP or PS do it automatically and seamlessly, but before you used to have to do it manually.  It's a matter of creating an alpha mask in your chanel, then saving the file in 24 bits PNG.  The alpha channel is important, as that's what determines the transparency.  I don't know if PSP supports chanels or not, but that's how it should be done if the software doesn't have an "export as transparent PNG" option.

For saving png files from PSP, go file > save as > options > run optimiser , in the colour tab select 16.7 million, in the transparency tab select Alpha Channel, then save

... or File > Export > PNG Optimizer .... gets you to the same place.

Or, using the Customize toolbars feature, place a shortcut to the PNG Optimizer on your tollbar for quick access......... (that's what I do)

It worked! Thanks Everyone! Now, one more question...how do I upload my works?

Now Im confused.

I keep making an image but when I save it the background appears white.
I must have missed something. Do I have to save it as a PNG, cause I keep trying to save as a gif or jpg. Please help. Im confused?

Yes, must be a png. Gifs and jpgs do not have an alpha channel.

Thank you. That worked.
I've been trying this all day.

FYI - In version 8x (or 9), go to file > preferences > file format preferences.
Click on the PNG tab and uncheck the Load and save transparency from / to alpha channel.
By doing this, your transparent areas will save properly.

Ok from what I've noticed. It is not possible to make the background transparent if you save as a JPG.

Gif's, PNG, and BMP all seem to work. Am I over looking something?

Thanks for this.
