When a bitmap image is used in desktop publishing applications, it is usually in the shape of
rectangle, because it is a raster image. Corel applications have several different ways of making
the background pixels of the image transparent so that the graphics behind will show through the
bitmap.  Eliminating a color can also alter the apparent shape of the bitmap.  For example, if you
have a bitmap with red text with a black background and you use the Bitmap Color Mask to make
black transparent, the bitmap appears to take on the shape of the text only.  In actuality, the
bitmap retains its original rectangular shape, but it will print and display without the black
background.

Working with Transparent Bitmaps in CorelDRAW  6 for MacIntosh  

Bitmap Color Mask
The Bitmap Color Mask RollUp allows specific colors to be hidden in a bitmap that has been
imported onto a CorelDRAW 6 for MacIntosh page.  However, the Bitmap Color Mask RollUp
will not work with black and white images.

1.  Import the bitmap image.
2.  Click the bitmap with the Pick tool.
3.  Click Effects, Bitmap Color Mask.
4.  Click Hide Colors from the list box.
5.  Click the Color Eyedropper tool, and move it over the bitmap.
6.  Click the color you want to remove.  The color appears in the Bitmap Color Mask RollUp.
7.  Enable the check box next to the color you selected, and click Apply.

Note:  Adjust the tolerance as desired using the slider provided. As you increase the tolerance,
CorelDRAW 6 for MacIntosh removes a broader range of colors around the color you selected. 
For example, if you click baby blue and increase the tolerance, CorelDRAW for MacIntosh will
remove pastel blue, electric blue, and so on.

Creating irregular shaped bitmaps for use in CorelDRAW 6 for MacIntosh
Bitmaps that are imported into CorelDRAW 6 for MacIntosh can be cropped using the Shape tool
to give them irregular shapes.

1.  Import the bitmap image.
2.  Click the bitmap with the Pick tool.
3.  With the Shape tool, click the edge of the bitmap you would like to change.  A dot will appear.
4.  Press +,  and a new node will appear on the edge of the bitmap.
5.  This node can be moved with the Shape tool, to change the shape of the bitmap.

Note:   The bitmap will retain its cropped shape if exported from CorelDRAW 6 for MacIntosh.

PowerClipping bitmaps in CorelDRAW 6 for MacIntosh
Objects in CorelDRAW 6 for MacIntosh can be placed into a container or shape using the
PowerClip effect.  These shapes can be used to hide the background of bitmaps in a manner
similar to cropping with the Shape tool.  Any portion of the bitmap that lies outside of the shape
will be invisible or transparent.  The main idea would be to create a shape that is identical to the
shape of the image you want to display in CorelDRAW 6 for MacIntosh.

1.  Import the bitmap image.
2.  Create a shape with no fill and a closed path; i.e. An ellipse or rectangle, not a line.
3.  Click the bitmap with the Pick tool.
4.  Click Effects, PowerClip, Place Inside Container, and click the shape with the large black
pointer.
5.  To position the image within the shape click Effects, PowerClip, Edit Contents, and move the
image with the pointer to the correct location.
6.  When finished click Effects, PowerClip, Finish Editing This Level.
7.  Click the Outline tool, and set the outline on the PowerClip object to none.

The image can now be placed onto other objects and will appear to have a transparent
background.
