Scanning and Patching Certificates in Corel Photo-Paint 10 or

later.

Dont Give Up After the First Try!

It will take a long time to patch together your firstimage. But the more you do it, the better you will

get.

Step 1: Identify Your Goal

If you are scanning certificates for images to put on

the web, you will not need high-quality images. In

most cases, 72 dpi (dots per inch) will be perfectly

adequate.

If you are scanning images to print, you will proba-

bly need to scan images at 150-200 dpi. Only when

you are scanning for high-quality print publicationswill you need to scan at higher resolutions.

The lower the resolution you scan at, the faster your

computer will work. Dont scan at too high a resolu-tion if you dont need to.

Step 2: Scan in Pieces

You can scan most stocks and bonds in two pieces.

Sometimes it will take three or four scans. Here are

the rules I have developed for my own scanning.

Always scan with the top of the certificate pointing

in the same direction. Do this so colors will be uni-

form, regardless of the accuracy of your scanner.

Scan in color. Or grayscale. Not in black and white.

Do not waste your time trying to get the cert ificateperfectly square on the scanner. You will just be

wasting time. Almost every low- and mid-priced

scanner has rotation peculiarities.

Scan against a white or light gray background. Avoid

black or colored backgrounds. Black backgrounds

make the paper look dark and dirty. Colored back-

grounds make the paper look tinted.

Finally, scan the pieces with LOTS of overlap.

Step 3. Increase the paper size to give yourself working room.

Pick one image that will serve as your base. I always use the left half for

horizontal format certificates. Or the top half for vertical format

certificates. Next, open the canvas size dialog box by picking Image >Paper Size from the menu bar.

The Paper Size dialog box will appear. In this example, the originalcertificate is about 14 wide, so I increased the width of the paper to 15

inches by typing 15 in the new width box. I next told PhotoPaint to

put the original image in the Center Left of the new space. Fortunately,

Photo-Paint gives you a preview of your choice.

ClickOK.

Now you have all the space you will need to the right

of the your first scanned image. You will next insert

part of the right half into this area.

Step 4. Copy part of the second image and paste it

into the newly-created space.

Select the Rectangle Mask Tool (the rectangle

with the dashed lines.) If it is not showing, click the

second button from the top and hold it down a few

seconds. More tools will fly out. Select the

rectangle.

Highlight a rectangular area

that you want to copy into your

base image. On horizontal

format bonds, it will normally

be best to select about half the

bond.

The trick is to overlap the area

covered by the first image byabout and inch or two. Do not

agonize over the accuracy of

your selection. Just make sure

you have enough overlap.

Copy the selection by choosing Edit > Copyfrom the menu bar.

Click your base image to re -activate that window.

Then paste your selection by choosing Edit > Paste> Paste as New Object from the menu bar. Theresult will look something like this.

Step 5. Make the new part of the image semi-

transparent.

From the top menu bar, select Window > Dockers> Objects.

A new box will appear that will give you the opportunity to

modify your image. Notice that when you inserted the second

half of your bond, Photo-Paint automatically created a new

layer. By default, Photo-Paint labels new layers Object 1,

Object 2, and so forth.

Make sure the Object 1 is highlighted.

Now click in the white area to the right of the word Normal.Type in 40 as shown. This will make that layer semi-

transparent. (40% of the layer is visible.)

Step 6: Align the new image inone small area.

Using the Object Pick Tool, slide the newpart of the image over your base image.

Since you can see through the image, youcan move it reasonably close to where it

needs to go.

Now, using the Zoom Tool (the magnifying glass)

zoom in close at either the top or bottom edges

where the images overlap


7/12

This image shows an extreme close-up of the area

just above the vignette. Note the semi -transparent

image does not line up perfectly with the base image.

Now, use the Object Pick Tool to slide the right

hand image until the images appear to merge.

The images will seldom be parallel, so move the

transparent image until it overlaps perfectly in one

tiny area. I usually line up images in an area with

text. I like to use circular designs such as periods, thedots above is, or the circular parts of letters.Always line up the images near the overlapped edge.

In this example, I lined up the letter E in

Preferred at the top part of the bond.

SAVE YOUR IMAGE AS A TEMP FILE right

now. This is a cautionary warning, because the next

step often causes Photo-Paint to fail on computers

with slow processors and minimal memory.

Step 7. Anchor the new image in one spot and

rotate the rest of the image into place.

You have now accurately lined up one part of the

image. Use that point as an anchor and rotate the rest

of the image around that point. Photo-Paint will

allow you to do that easily.

Imagine the rotation process as the electronic

equivalent of sticking a pin through the top image

and rotating the picture around the pin.

To start the process, click once or twice within your

new image until a rectangle appears with eight small

arrows around the outside.

Do you see a circular target in the center of the box?

That point is the rotation point. You can move it

around with your cursor.


8/12

Grab the rotation point and move it into the spot that

you just matched up. In this case, I used the E in

Preferred.

Using your scroll bar, pan to the opposite side of the

image. (In this case, the bottom of the bond.)

Since the images were scanned at a slightly differentangles, the letters at the bottom do not quite line up.

To rotate the image, move your cursor over the

arrow in the bottom corner. Your cursor will turn

into cross-hairs. Click and pull the arrow either left

or right to rotate the image around your rotation

point.

Go slow. Be patient. This is a numerically complex

process because millions of dots need to be

recalculated. Photo-Paint sometimes bogs down with

large images during this step.

When you have matched the images properly, doubleclick within the image to accept the new rotation.

Step 8. Change the opacity of your top image back to 100%.

Go back to your Objects Docker. Object 1 should still be

highlighted. Change the opacity back to 100. By now, your

certificate will look nearly perfect.

Step 9. Merge your images.

While your certificate will look good, it is still in two separate layers.Merge your images by going to the top menu bar and selecting ,

Object > Combine > Combine Objects With Background.

You now have an image of the entire certificate. Save your image

again.

Step 10. Crop and rotate the image.

Photo-Paint allows you to crop and rotate images in

one operation. This step is a lit tle tricky the first timeyou use it.

First, zoom into an area of your certificate that has

horizontal features. Often, bottom margins or lines of

text work well. Next, select the Deskew Crop Tool

from the toolbar. Draw a box two or three inches

long near that horizontal element.


10/12

Page 10 of 12

In this example, the deskew crop box is not quite

parallel to the bottom border. Click once or twice

inside the crop box and rotational arrows will appearlike they did earlier. (They are hard to see.)

Using your cursor, rotate the box with one of the

corner arrows until the box is parallel with the border

or text. Click inside the crop box one more time to

get rid of the arrows.

Use your F3 button (notthe zoom tool), zoom out so

you can see the whole certificate.

Then, by grabbing the small boxes around the cropbox, expand the crop box until the highlighted area

shows the entire certificate. In this example, because

scanning was not perfect, the crop box appears tilted.

As soon as you hit ENTER, everything outside the

highlighted area will disappear and your image willrotate into its final alignment.

Step 11. If necessary, resize your image at your

intended resolution.

In Step 1, you determined your target resolution. If

you scanned at a higher resolution, you will want to

adjust your resolution for your final product. As

mentioned before, if you are publishing for the web,

a resolution of 72 dpi ought to be sufficient. Often I

will scan at a 200 dpi resolution so I can print a

copy. Then I re-size the image to 72 dpi for the web.

Open the Resample dialog box by clicking Image> Resample from the top menu bar.

In this example, I set the resolution to72 dpi.

At the same time, you can resize the

image so it will fit on a web page or aprinted page. I find it easier to adjust

the longest dimension, and let the

shorter dimension take care of itself.

Generally, when I intend to print a

certificate, I set the long dimension to6 or 7 inches at 200 dpi. For web im-

ages, I usually keep the size to about 4

inches at 72 dpi.

Experiment at various sizes to see

what works best for you.

Step 12. Save your image.

Saving in Photo-Paint is easy. Choose File > SaveAs. If you are saving for your own use, use thedefault CPT format. If you are going to use images

in other programs, or if you are going to send them

to other people, save as TIF, JPG, or GIF.

Most programs handle these formats reliably. TIFimages are very large in comparison to JPGs.

Generally, I save in JPG format if I do not intend to

re-size the image later. If I expect to alter the image

at some later time, I use the TIF format which is

more forgiving when an image is resized.

When saving to a JPG format,

a new JPEG Export dialog

box will pop up. This allowsyou the option of saving high

or low quality images. (High

quality = large files.) I have

tested JPGs extensively and

suggest that you will rarely

need image quality higher

than 30.

Photo-Paint also allows you

to save your images in aspecial interlaced GIF

format. This format, when

used on the web, allows

grainy images to appear onthe screen very quickly.

Gradually, as the file loads, the image resolves

into better and better resolutions. The interlaced

GIF format is very good when you think

viewers will be impatient. File sizes, however,

tend to be much larger than JPGs. To save in

this format, select File > Export > GIF andfollow the directions. Near the end of the

process, select Interlaced from one of thecheck boxes you will encounter.
