Now, to apply a Spiral Shape, from the Gfig’s upper Toolbar, click the following Create spiral button.
Then left-click over the centre of the dialogue box’s white canvas, and drag out (draw) a Spiral Shape - as illustrated below.
Resize And Rotate Your Shape
To Rotate your Shape, (before releasing the mouse button): simply move your cursor in a semicircular (or a full circle) movement - as illustrated below.
To Resize your Shape, (before releasing the mouse button): drag your cursor outwards or inwards; as illustrated below.
As soon as you release your mouse button, a (Spiral) Shape will be applied to the Gfig’s White Canvas - as illustrated below.
If you don’t like the applied shape, then you can return your image to a previous state by pressing Ctrl then Z.
After you have applied your Spiral, you are ready for the next step.
Now, to change your Spiral’s Fill, click open the following Fill tab, and from the subsequent drop-down list, select a Fill (or No Fill) of your choice.
(I have selected Shape gradient).

To finish, from the top menu, choose Image and then choose Flatten Image.
To create extra impact, apply a Sharpening Filter of your choice - Filters then Enhance.
Congratulations, your Gfig Shape is complete and your work is ready to optimise and save.
This filter is a tool: You can create geometrical figures to add them to the image.
When using this filter, elements inserted in the image will be placed in a new layer. So the image will not be modified, all modifications occurring in this layer.
The Preview (with a horizontal and a vertical ruler) on the left of the main window actually is your working area where you are adding your figures.
You can add and modify figures using the Gfig tools and using the appropriate options.
The Gfig Toolbar
At the top of dialogue, you can find a set of icons which represents the functions of this filter. Help pop-ups are explicit.
Functions For Object Drawing
On the left part of toolbar, you can find some functions for object drawing. You enable them by clicking on the corresponding icon. You can create the following objects (note that Control points are created at the same time as object).
With this tool, you can draw lines. Click on Preview to mark start point, then drag mouse pointer to the end point.
With this tool, you can draw rectangles. Click on Preview to mark start point, then drag mouse pointer to create the rectangle.
With this tool, you can draw circles. Click on Preview to mark centre, then drag mouse pointer to the wanted radius.
With this tool, you can draw ellipses. Click on Preview to mark centre, then drag mouse pointer to get the wanted size and form.
With this tool, you can draw circle arcs. Click on Preview to set start point. Click again to set another arc point. Without releasing mouse button, drag pointer; when you release mouse button, the arc end point is placed and an arc encompassing these three points is drawn.
Create Regular Polygon
With this tool, you can create a regular polygon. Start with setting side number in Tool Options at the right of Preview. Then click on Preview to place centre and, without releasing mouse button, drag pointer to get the wanted size and orientation.
With this tool, you can create a star. Start with setting side number (spikes) in Tool Options at the right of Preview. Then click on Preview to place centre and, without releasing mouse button, drag pointer to get the wanted size and orientation.

Create Bezier Curve
With this tool, you can create Bezier curves. Click on Preview to set start point and the other points: the curve will be created between these points. To end point creation press Shift key when creating last point.
Functions For Object Management
In the middle of toolbar, you can find tools to manage objects.
Move An Object
With this tool, you can move the active object. To enable an object, click on a control point created at the same time as the object.
Move A Single Point
With this tool, you can click-and-drag one of the control points created at the same time as object. Each of these points moves the object in a different way.
Copy An Object
With this tool, you can duplicate an object. Click on an object control point and drag it to the wanted place.
Delete An Object
Click on an object control point to delete it.
Select An Object
With this tool, you can select an object to active it. Simply click on one of its control points.
Functions For Object Organisation
At the right of toolbar, you can find tools for object superimposing (you can also get them by clicking on the drop-down list button if they are not visible). You have.
Up (Raise Selected Object), Down (Lower Selected Object)
With this tool, you can push the selected object one level up or down.
Functions For Object Display: Back, Forwards
These functions allow you to jump from one object to another. Only this object is displayed.
Show All Objects
This function shows all objects again, after using both previous functions.
The XY position shows the position of your pointer.
If the selected tool provides some options (like number of sides), you can change them here.
If this option is marked, the object will be drawn. Two buttons are available, to select colour and brush type. Changes to colour or brush apply to existing objects too.
With help of this drop-down list, you can decide whether and how the object will be filled, with a colour, a pattern or a gradient.
If this option is marked, a grid is applied on Preview to make object positioning easier.
Snap To Grid
If this option is marked, objects will align to the grid.
When this option is marked, the current image is displayed in Preview (working area).
