How to vector a bitmap with Corel Draw X8

I know there are easier ways to get rid of the background in a bitmap, but I’ve never been able to achieve the crisp results I wanted, so instead I apply nodes to the bitmap, effectively turning it into a vector of a bitmap.

What do I mean? I’ll explain with a real life example. This is the image I downloaded from freeimages.com:

The reason I downloaded it was because I wanted those two gears, and only those two gears. This is what I ended up with after 3 days of boring, painstaking work:

 

As you can see, the gears now appear in splendid isolation, crisp and clear, as if I’d photographed them against that dark charcoal background. This is how I did it.

Step 1 – Use the File/Import command [Ctrl I] to bring the bitmap file into Corel Draw X8.

Step 2 – Select the bitmap and click the Shape Tool as shown:

Step 3 – The bitmap should now have nodes displayed at each corner.

Right click anywhere on the ‘lines’ between the nodes to place a new node and open the right click menu:

 

Step 4 – From the right click menu select the ‘Add’ option. This will give you a new node to work with.

Step 5 – Use the Shape Tool to move the new node to the edge of the shape you want to bring out. At this point the lines between nodes will all be ‘straight’:

Step 6 – [optional] As this point I usually create a dark coloured, vector rectangle and place it behind the bitmap so I can see the shape, and its background, more easily. Use the Object/To Back of Page command to locate the rectangle behind the bitmap.

Step 7 – To mold the lines around the bitmap shape, you have to make them capable of bending into a curve. To do this, right click the node you want to change to a curve. The context sensitive menu is displayed again. This time, select the ‘To curve’ option.

Step 8 – The line between nodes should now display two directional arrows:

Click-hold-and-drag the directional arrows to create the required curve.

For the teeth of the gears, I had to use about 5 nodes for each tooth:

As you create the vector shape around the bitmap shape, the coloured background will be revealed, proving that the emerging shape no longer has a background. And of course that means you can place it on top of other images like so:

Ta dah! Not completely finished but it’ll do for now. Oh and I finally worked out how to stop the CMYK black from displaying as grey when converting to an RGB image. Soooo simple.

With the Corel Draw X8 screen displayed, select:

Tools/Color Management/Default Settings

This is will cause a popup window to be displayed. Find the Color Conversion Settings and change the Color Engine to ‘None’:

Now the blacks will stay black instead of displaying as a kacky grey. 🙂
