Chapter 6: Creating Drawings with Draw

Replacing colours using the Eyedropper

In Draw and Impress, images inserted in a bitmap format such as, GIF, JPEG and metafile

images like WMF can have their colours edited using the Eyedropper. To open the

Eyedropper window,choose Tools > Eyedropper.

The Eyedropper can replace selected colours and, to a point, similar colours, with other

colours, up to four colours at one time. If the replacement is not what is desired or needed,

reverse it with one click on Undo on the Standard toolbar. Use the Eyedropper to match the

colours of different bitmaps or to redo a bitmap with, say, the colours of a company logo.

The Transparency attribute also serves as a colour. Transparency, in an image with a colour,

can be replaced for example, with white. This is Helpful when, for example, the printer

driver has problems with printing transparent graphics.

If the user wants to produce an image on HTML pages to publish in the Internet, like the

illustration of a product, for example, it usually looks better when one does not see a

rectangular picture, but rather sees only the illustration of the product against the uniform

background of the web page. If there is a white background in the picture behind the product,

use the Eyedropper to replace the colour white with “Transparent” (i.e. no colour) and save

and/or export the image in a format that supports the transparency attribute (such as GIF).

When using this method, be sure that the illustration of the product itself does not contain

any white parts, since these would also become transparent just like the background.

To replace colours with the Eyedropper

1. Insert an image in a Bitmap format (e.g., BMP, GIF, JPG, TIG) or in a metafile format like

WMF. To do this, choose Insert > Picture in Draw and Impress.

2. Open the Eyedropper window by choosing Tools > Eyedropper.

3. In the Eyedropper window, click the Eyedropper icon in the upper left-hand corner. The

mouse pointer will turn into a special pointer with which one can indicate the colour to be

replaced in the current document. The colour box next to the eyedropper icon in the

Eyedropper window displays the colour the mouse pointer is resting on.
