Open the image in Corel PhotoPaint

Right click on the image and select EDIT | BITMAP (1). This will load your image into Corel PhotoPaint. There will be a special link between the file so any changes done to the file in PhotoPaint will be transferred to the file in CorelDraw

Our image is open in Corel PhotoPaint

media_1270064863828.png

Our image is open in PhotoPaint but still connected to the file in PhotoPaint. If you cannot see the whole image hold down the shift key than the F4 key

We need to open up the Cutout Lab

media_1270064960835.png

Select IMAGE | CUTOUT LAB (1). Cutout lab will open up

We need to select the highlight tool

media_1270065056843.png

Our first step is to select the highlighter tool. We use this tool to place a line on our image so that it is half way between the image we want to keep and half off of the area that we want to get rid of. We will use the highlighter tool to draw this line. Select the highlighter tool (1). We can change the width of the line via the “nib” size (2). The highlight colour is the colour of our line (3).

Start drawing your line

Now with the highlighter activated go to your image and left click at the bottom of the image. Do not leave any space between the image and the bottom of the page (1). With your left mouse button held down start dragging you mouse so that it is half way on the image (the man) and half off of the man (the background). Do not worry you can let go of the mouse and stop dragging and turn around and start drawing where you left off.

You can zoom in on the image to improve our accuracy

A lot of times it is easier to draw your line when you are zoomed into the image. To pick the zoom tool you can select the icon with the “+” symbol in it (1). Than click on the area or draw a selection window.

Draw a zoom window

While holding down the mouse drag a window around the area you want to zoom in on

Hold your left mouse button down to keep drawing

Now that we are zoomed in on the image we can start drawing our line more accurately. Hold down the left mouse button and start dragging. To move to another part of the image you can press the “H” key and your cursor will turn into a hand. With the hand tool you can click and drag the image to where you need it. Once you are done moving the image press the F5 key to continue drawing your line.

Trace your image with the highlighter tool

Make sure that the whole image is highlighted with your green line. Make sure that the line goes to the bottom of the screen.

Now we need to place a fill in the highlighted area

media_1270065604260.png

To select the fill tool click on the paint bucket icon (1). The reason we need to use the fill is because this will tell the computer what part of the image we want to keep. So we fill the man as this is what we want to keep.

Our image filled

Our image is filled by clicking inside the image and filling it

Now we can preview the image

Our background has been knocked out

You can see that the background has been knocked out pretty well. There are some areas that need to be cleaned up.

We can bring back or take away wanted or unwanted detail of the image

media_1270065754602.png

To bring back some lost detail click on the “Add Detail” icon (1) – Hot key “A”. To get rid of the detail click on the “substract detail” (2) – Hot Key “R”

We now need to bring back the areas that where taken away that should not have been knocked out

media_1270065754602_1.png

To bring back some lost detail select the “add detail” icon (A). Now your mouse will turn round. You can change the size of the nib as you did with the highlighter tool. Now place your cursor over the area and hold the left mouse down and drag the mouse back and forth to add detail. You can click successively to add small detail. To move around press the “H” key and drag the image. Press the “A” key to start adding detail.

Remove detail in your image

media_1270065822977.png

To remove detail select the “remove detail” icon or press “R” (1). To increase or decrease the nib size increase or deacres the number in the nib setting dialogue box (2).

Identify the detail to remove in your image

Click the “remove detail” button or press the “R” key.

Our image has been cleaned up. This process took 5 minutes.

You can preview your image on a different colour background

media_1270066131917.png

You can preview your image on a different coloured background (1). Select one of the backgrounds to see more clearly any partial concealed traces of your original image.

Here is the finished image

You can show the original image in the background

media_1270066390825.png

You can also show the original image in the background. This makes it easier to see what detail needs to be removed or kept (1). Make sure you have turned off the background (2).

The original image is in the background

media_1270066437700.png

You can see the original image in the background.

Click Ok to exit the cutout lab

media_1270066586233.png

Now that we have removed the background we can click “OK” and our image will go back to PhotoPaint.

Click “Save” to send the finished product to CorelDraw

media_1270066598784.png

Once you are done click the FILE | SAVE to save the finished image back to CorelDraw (1).

Here is our image in CorelDraw

media_1270066621730.png

Here is our image in CorelDraw. It has been automatically updated. The image is also transparent. This means that we can place a coloured background behind the image.

Coloured Background

media_1270066656589.png

We have a coloured background on our image because the background is transparent

Save as a CPT file to preserve the transparency

media_1270067193099.png

If you have opened up your image in Corel PhotoPaint and want to take it to CorelDraw you will need to save the image as a CPT file or Corel PhotoPaint image. This will preserve your transparency.

Type in a file name

media_1270067204484.png

Type in your file name (1) and select the CPT file format (2). Place any noted for the file that you want in the file (3).
