transparent background

Hi, maybe my question is one of the most simple ones, but being my first steps with gimp I have no idea on how to proceed. I am not even an experienced user of PaintshopPro or other software like this.

1st problem: I have a *.gif file with white background and black and red graphics on it. Now I need a transparent background to be able to adapt this graphic to any webpage as backgrounds will have changing colours. Could you please tell me how to reach this? Is there an online-resource somewhere?

2nd problem:
I have a *.gif file (banner) with basic colour - let's say red, but it is not a unique red - it is already some kind of texture, marble or similar. Now I need to change colour shade - let's say from red to blue - is there a way to do this?

Thank you so much for any hint - in any case I will create an online-"how to" for all the questions I am asking and translate it into Italian and German (my languages).

And as we are talking about this: is there some kind of glossary for English/German/Italian around, just to be sure to use the right terms.

Thanks again - probably you'll need quite a lot of patience with me.

All the best, Sabine

Hi Sabine

1st problem:

First you have to add an alpha channel (RMB --> Layers --> Transparency --> Add Alpha Channel). Then you can select the white background with either "Select by color" (Shift+O) or with the "magic wand" (is this the right word in english...? in german it is "Zauberstab") (Z). Then you just need to cut out the selection an it will be transparent. Save it as xcf, png, tga, gif or any other file that can handle transparency.

2nd problem:
I have a *.gif file (banner) with basic colour - let's say red, but it is not a unique red - it is already some kind of texture, marble or similar. Now I need to change colour shade - let's say from red to blue - is there a way to do this?

The easiest way is to change the "Hue" of the red part of the image. Do this by selecting RMB --> Layer --> Colors --> Hue and Saturation.

Hope, this helps...

There are two even:

You could use the GIMP translation files that you will find in he po directory of the GIMP source code. Or you could change your locale and look at GIMP in english, german and italian.
