Can I produce a jpg with a transparent background?

[tonygamble]

I need one to put some text into a web published image.

The system I am using creates watermarks by using jpgs of text but they need the background to be transparent rather than white.

The jpg I have offered shows the text with a white background. I think there are third party programs that will make the background transparent but before I start looking for one I wondered if PWP would do it for me.

Many thanks

As far as I known PWP7 does not handle transparency.
I even do not know how transparency is handled with JPGs.
If I need an image with transparency for web I use PNG and create this with GIMP.
PWP7 does not handle transparency with PNGs.

Thanks Winfried.

I'll use GIMP.

I was having a fiddle with Mask as I guessed those were transparent - but with no success so far.

Gosh it's complicated if you have not used GIMP before.

Do you have a URL with some instructions?

What I have so far is my PWP jpg with my text in colour against a white background. I need to turn the white to transparent and save as a PNG.

I read about Alpha channels but am still in the dark.

Sorry, I am not a GIMP specialist.
But some hints.
- You need to start with a rgb-image
- You will find the command unter colours | colours to transparency (I retranslated the German texts to Englisch texts)
- next problem is the fileformat: You need to use the export command from the File tab, because "Save" just saves an images in the GIMP *.xcf-format.

I hope this will help a little bit

Thanks Winfried,

I am stuck.

I have emailed the man who runs Juicebox, which the web builder I am trying to move to.

I'll see if he can help.

I have done what you suggest but probably one tick box is wrong !!

Wilfried.

The crucial thing when you create a New Image is to go into the Advanced drop down and pick Transparent Background.

After that it is far more intuitive and how you get back to Transparent if you opt for an ordinary (default) background I never puzzled out.

As always Google/YouTube was the saviour.

I do not believe that JPEG supports transparency. PNG and GIF and to some extent TIFF support transparency, but PWP does not support it.

Thanks Jonathan,

I've got what I need as a .png from GIMP.

This is an example of my new Juicebox web folders - with a GIMP watermark.
