Hello,

when I double-click on an image, I enter PREVIEW mode

I have a black object on an invisible background. I would like to change this object to brown.
On Windows, I used PAINT, and I could make it brown immediately.

On Mac, I don't know how to do this while keeping the background invisible.

I hope I didn't confuse you

Thank you!!

Configuration: Mac OS X / Firefox 3.6.7

Hello,

In all image manipulation software, you can only keep the transparent background by saving it in .png format, which Preview can do.

Now, since you don't provide any explanations, I don't know what format you're starting from, nor how you were changing the object from black to brown in Paint, and then in which format you were saving it afterwards.

Preview can do a lot of things, including making a background transparent with the "select / Instant Alpha" tool, but it is not strictly speaking a drawing or coloring software like Paint.
However, if your file already represents an object with a transparent background, it should retain that after being processed through Preview, if saved as .png.

For Mac, there are equivalents to Paint, such as Paintbrush, for example.

hello

yes indeed I am working with PNG, which allows me to insert my image into a page without having a white border.

I just tried paintbrush, but even saving as PNG, it keeps the white background

Would you happen to know how to avoid this please?

thank you again!

It works for me, with Preview and Paintbrush.

It might just be an impression that it's not working, because when placing the image on the desktop, for example, a white background is seen, but if you test putting the image in a Safari page, or better yet, copy-pasting the image onto an existing one, you'll see that the background is indeed transparent.

I just did a quick test, and I confirm that it works well for me.

Oh no, unfortunately, it is indeed a PNG image with a transparent background, but when opening it in Paintbrush to change the color, the background turns white.

There must be a setting to change, I will look into it. It's not a big deal, thanks anyway for the help.
