Setting a transparent color on an image
You can choose one color in any image in a Web document and make that color transparent. When an image has a transparent color, things “under” the image—such as the page background—show through the transparent areas.
In the example below, both Santa Claus images have white backgrounds, but the one on the right has been modified so that pure white areas are transparent. You may notice that the alpine background image also shows through those parts of the second figure’s mustache and headgear that are pure white.
The figure on the right uses transparency
When you set a transparent color on an image, Namo WebEditor creates a copy of it in GIF format, which is the most popular Web image format that supports transparency. If the original image is not GIF, Namo WebEditor will convert it to GIF when it creates the copy. To avoid deleting the original image file, you should specify a different name or path for the transparent copy.
To set a transparent color on an image
- Click the image you want to make transparent.
- Do one of the following:
-
- Right-click the image, point to Image, and then click Set Transparent Color.
- Click the Layout tab, move to Effect, and then click Set Transparent Color.
- Click an area of the image that is the color you want to make transparent.
- In the Save as box, enter the path and name of the transparent GIF file to be created. (Leave the path and name unchanged if you want to replace the original image file.)
- Confirm that the color shown in the Transparent color box is the one you intended to make transparent, and then click OK.
When you paste an image from another program, you can immediately set a transparent color on it. In the Paste Image File As dialog box, click the Transparent color box and select the color to be made transparent.
