Somes of the screenshots needs to be updated with 0.64.0

Create a new document.

Image:magnifying_glass_02.png

Insert a circle layer, this will be the outline of the magnifying glass, so I want another color,

Image:magnifying_glass_03.png

I chose brown

Image:magnifying_glass_04.png

and name it "outline".

Image:magnifying_glass_05.png

Make another circle layer, right-click choose copy and then paste,

Image:magnifying_glass_06.png

click on the light blue spot and make the radius a bit smaller

Image:magnifying_glass_07.png

Choose "alpha over" as blend method in layer parameters

Image:magnifying_glass_08.png

and you'll end up with a hole.

Image:magnifying_glass_09.png

I name this layer "hole"

Make a third "circle layer"and set a new color with transparency. This layer will be the glass.

Image:magnifying_glass_11.png

Now it looks like this.

Image:magnifying_glass_12.png

Then I chose the Spline Tool to make the handle.

Image:magnifying_glass_14.png

In tool options I'll see to that I only have "Outline" checked, I don't want to have it filled.

Image:magnifying_glass_15.png

Click on the glass outline with the Spline Tool and make your handle,

Image:magnifying_glass_16.png

choose the outline width in layer parameter and increase to 14pt.

Image:magnifying_glass_17.png

Image:magnifying_glass_01.png

Choose all your layers, 3 circle layers and one Spline layer and group them by right-clicking.

Image:magnifying_glass_20.png

I name the group layer "magnifying glass"

Make a new layer, choose "Spherize". Lower this layer to the bottom (this is the magnifying effect and all that is under this layer will be magnified)

Image:magnifying_glass_22.png

Then chose the "magnifying glass" group, go to layer parameters and right-click on "Zoom" parameter, chose "Export".

Image:magnifying_glass_24.png

a window appears and ask you for a name for this exported value, I name it "zoom".

Image:magnifying_glass_25.png

Click on "Spherize" layer, go to layer parameters and right-click on "Radius", chose "Convert/Exponential".

Image:magnifying_glass_26.png

Click on "Library" tab and find the exported "zoom" value, click on that, go back to "layers" tab and click on Spherize layer if it's not already chosen.

Image:magnifying_glass_27.png

In parameters the "Radius" has a small triangle, click on it to open up it's sub parameters, right-click on "Exponent" and chose "Connect".

Image:magnifying_glass_28.png

Now the radius of the Spherize layer will be connected to the zoom of the group layer called "magnifying glass", so if you zoom in/out on with it, the spherize layer will follow.

I will also need to connect the origin in the Spherize layer to the origin in the group layer.

I click on the Spherize layer and the green little spot will be visible, that's the origin, click on it and drag it a little bit aside (that is because it covers the group origin, I want to choose them both and link them together.

Image:magnifying_glass_34.png

Control-click on the magnifying glass layer so you'll get both layers activated,

Image:magnifying_glass_35.png

then you'll also see that layers origin, control-click on both origins so they will be highlighted then right-click and choose "link" from the pop-up menu.

Image:magnifying_glass_37.png

Now when you move the magnifying glass layer, the spherize layer will follow. I will need something to zoom in on, so I import an image file that I put "under" the Spherize layer.

Image:magnifying_glass_30.png

The "amount" in the spherize parameters decide how much magnifying effect it will have, try it out, you can also use negative values.

Image:magnifying_glass_39.png

I want to be able to rotate my magnifying glass so I make a new "rotate" layer inside the magnifying glass layer, I put it on top of all other layers inside, the rotate layer only affect the lower layers.

I also made a "bevel" layer inside magnifier glass layer to make it look less flat. You can study the settings for those extra layers if you download the Synfig file (the image used is also in this archive).

This tutorial is also available in PDF format, and the rendered movie is on YouTube.
