in this tutorial, we're going to examine the Pointilizer Extension within CorelDraw X8.
Pointilizer allows you to generate high-quality vector mosaics
from a number of selected objects, vector graphics, or bitmaps.
The output is highly customizable, and offers a variety of effects ranging from precise halftone patterns
to playful effects that resemble pointillism art.
To access this extension if you've already purchased it,
go to the Effects menu, and then down to Pointillizer.
If you have not already purchased it, go to the Get More tab from Windows
down to Dockers, and select and Get More.
Select the Extensions tab, and here you'll find Pointillizer
with the ability to purchase it.
This is done through a secure payment wall.
Once you have opened the Pointillizer Docker,
select your image and modify the settings to customize and fine tune your vector mosaic.
I'm going to zoom into the image with a Shift+F2,
and now lets take a look at the various settings that we have within the Pointillizer docker.
Density allows you to adjust the number of tiles per square inch.
Scale allows you to adjust the size of all tiles by scaling them up or down.
Values higher than the default value of one increases the tile size,
wheras values lower than one would decrease the size.
Screen Angle allows you to set the angle at which the tiles will appear.
Keep Original of course will keep the original image on the page, and then apply the effect overtop of that.
We have the ability to limit the colors, and I can have a maximum of 256 colors
To Tracing Options. Methods lets you choose a technique for interpreting the source graphic.
The three tracing methods are: Uniform, Size Modulation One (Opacity), and Size Modulation Two (Luminosity).
Uniform, or Matte White, uses tiles of the same size to generate the mosaic.
Transparencies are flattened against a white background.
Size Modulation One interprets the source as a series of tiles that vary in size, based on sampled opacity values.
The more opaque or less transparent the areas are, the bigger the tiles are.
And of course Size Modulation Two: Luminosity
interprets the source graphic based on its brightness values.
Brighter areas in the source are rendered as smaller tiles, darker areas are rendered as bigger tiles.
Merge adjacent tiles lets you specify the maximum number of tiles of similar color
to be combined into a single tile.
This setting has affects only if there's enough space available.
Weld Adjacent Tiles allows you to weld together overlapping tiles.
Enable this check box to render the output in a cluster of colors.
Disable this check box to preserve more detail.
And finally, Shape.
There are three options here. We have Circle, Square,
and of course Custom.
Now let's take a look at the type of effect that this can create.
I'm going to go with these default settings here.
Let me drop my Merge Adjacent down to one,
and I'll simply click on Apply.
Notice how quick the effect is.
Let's go through and play with some of the settings now.
I'm going to do a Ctrl+Z to undo this.
I'm going to increase my density to about 20
and I'm going to leave the scale at one.
Simply click Apply, and you can see what the difference is.
CTRL-Z.
I'm going to take the scale, I'm going to make that . 75,
and again, Apply.
Very quick and very easy to create that type of effect.
Lets go on to my next image.
Again, select the image, Shift+F2 to zoom into that.
I'm going to change this to a square.
I'll leave the settings as they are, and simply click Apply.
So again very quick to create a pseudo halftone pattern.
Let me adjust these settings a little bit. Let's go up to 1.25.
I'll do a Ctrl+Z to undo this.
And then apply it again.
Now of course if I didn't do the undo and I simply applied it again, it would apply it to the existing image.
In other words I'd be adding that effect twice.
I'm going to do a Shift+F4 to zoom out.
And I'm going to show you a custom one. So we'll do a Page Down.
Custom allows me to take an object and use that as my pattern.
I want to go over to my Basic Shapes, going to select Heart,
draw a little heart on the screen,
and it's simply a matter of selecting custom.
I'll select my object - in this case it's piece of text.
I'm going to leave my screen angle at zero, and simply click Apply.
Now, I've left the density at 20, and the scale at 1.25.
Notice it's a little bit slower for that process.
And now I'm going to zoom in, and you can see what that looks like.
Let me just do a Shift+F2 to to zoom back out.
I'm going to do a Ctrl+Z to undo.
Let's drop the density down to 10,
and we're going to drop this down to 1.0.
Let's put this on a bit of an angle as well.
Let's give it a 30 degree angle.
And simply click on Apply.
So very easy to create a stunning effect with this.
If you want to get a little bit fancier, I'm going to control Z to undo this.
And now I'm going to take Merge Adjacent, I'm going to increase that, and watch this.
Simply click on Apply, and there's a pretty cool effect.
Then I can go ahead and print on a card. I can do any number of things with this.
If I'm doing sublimation or screen printing, maybe I want to print this on a t-shirt or something like that.
Now, I've been using raster images and pieces of text.
Let's take a look at a clip art image. Go to my next page, and it will be the last one.
Do a Shift+F4 to zoom to everything on the page
I'm going to select this clip art. You can see it's 14 objects.
i'm going to use the circle pattern,
and I'm going to leave the merge adjacent as is.
Simply a matter of clicking on Apply, and you can see the effect that that's giving you.
Kind of a fun tool to play with. Thanks for watching.
