Creating a launcher icon with Inkscape template 1

Note: The necessary template file is available in the Nokia Icon Toolkit.

This template is most useful if your logo or icon graphic consists of one single or very basic shape. The template includes a canvas in the correct icon size, a 43 x 43 px bounding box, the Series 40 Colour Spectrum, and several precast background layers with the surround shapes of Symbian launcher icons. These enable you to simply paste your graphic/glyph on top of the surround background shape of your choice, add the inner shadow, and export the icon as a PNG file.

Tip: When you start Inkscape, the interface does not show all palettes and dialogues you might need to create an icon. Below are some helpful shortcuts that place everything you need on the desktop.
     
Full Screen Mode   F11
Layers palette   Shift + Ctrl + L
Alignment Settings dialogue   Shift + Ctrl + A
Fill and Stroke dialogue   Shift + Ctrl + F
Swatches palette   Shift + Ctrl + W
The region of the canvas that is visible can be changed:
Pan in all directions   Scroll Bars (Ctrl+B)
Pan up and down   Mouse Wheel
Pan sideways   Shift + Mouse Wheel
Zoom   Ctrl + Mouse Wheel

Start

Open the template file “1_S40_FT_Launcher_Icon_Inkscape_Template_PRECAST.svg” via the menu bar (File > Open > select file to open). If you just drag the template onto an Inkscape canvas, it will not contain all of the necessary layers. This template is most useful if your logo or icon graphic consists of a single basic shape. You can then simply paste this shape on top of the pre-designed icon backgrounds provided in the template. To do so, please follow these steps below.

Note: You can’t copy objects from AI documents to Inkscape, but it is possible to save AI documents as SVG and open them in Inkscape.

Place your glyph

Activate the layer PLACE YOUR GRAPHIC HERE and draw your graphic onto this layer. You can cut the graphic from another layer (Ctrl + x) and paste it onto the layer PLACE YOUR GRAPHIC HERE (Ctrl + Alt + v pastes the graphic in place). Select File > Save as (Shift + Ctrl + S) and save the file with a new name in the directory of your choice.

Scale your graphic

Scale your graphic to fit the dimensions of the background below, and place it in the centre of the Focal Zone (guides). Elongated elements may exceed the recommended “Focal Zone” by a few pixels. It may be necessary to temporarily group your graphic (Ctrl + g) to scale it proportionally (keep Ctrl + Shift pressed and move the handles of the graphic), but afterwards you should ungroup (Ctrl + Shift + G) the graphic again. Centre the graphic with the help of the “Align and Distribute” dialogue, as shown in the screenshot below.

Try to attach as many vector lines and nodes/dots as possible to the lines of the pixel grid to achieve a sharp graphic in your exported PNG in the end (i.e., with as little anti-alias effect in unnecessary places as possible). By using the tool “Edit path by nodes” you can drag the nodes to follow the pixel grid lines.

White glyph

Set the colour of your glyph graphic to white in the Fill and Stroke dialogue, as shown in the screenshot below.

Select a background

Choose a background from the Layers palette by clicking on the “eye” sign of the background colour you wish to use. (You can hide the document grid if you don't need it anymore by pressing the "#" key.)

Create inner shadow

Activate the glyph on top of the background, and then copy it to the clipboard (Ctrl + c). Activate the layer CREATE INNER SHADOW HERE in the Layers palette, and paste the glyph shape in place (Ctrl + Alt + v) onto this layer. The new inner shadow of the glyph is now behind the glyph. You might want to lock the PLACE YOUR GRAPHIC HERE layer by clicking its lock symbol in the Layers palette to make sure that you don’t accidentally activate the glyph instead of the shadow in the following steps.

Set inner shadow opacity

Set the colour of the shadow to black with reduced transparency, as shown in the screenshot below (circled area at the right-hand side). Move the shadow one pixel down by subtracting one pixel from the original “Y” co-ordinates (circled area at the top of the screenshot).

Apply inner shadow blur

Activate the inner shadow and make sure that it is a simple “Path” object. To create the shadow blur, the inner shadow cannot be a group of objects or a combined object. To ungroup an object, select Object > Ungroup (Shift + Ctrl + G). To break a combined object apart, select Path > Break Apart (Shift + Ctrl + K). To convert a regular shape or text object into a path, select Path > Object to Path (Shift + Ctrl + C) or Stroke to Path (Alt + Ctrl + c). Activate only one object of the inner shadow, and select Inset/Outset Halo from the Extensions > Generate from Path menu. When you insert the data shown in the screenshot, and then click Apply, Inkscape creates several transparent shadow layers that create the illusion of a blurred shadow.

Note: If the inner shadow is not a single object with an editable path, the function Inset/Outset Halo does not work.

Figure 8.

Keep the original shadow layer activated and set its opacity to 8, as shown in the screenshot below, to finalise the inner shadow. If you can’t activate the original inner shadow below the shadow blur, you can change the order of objects by activating the blur shadow, selecting the Object function from the top menu bar, and reordering the objects by selecting Lower to Bottom. This will move the shadow blur behind the original inner shadow, so that you can easily activate the inner shadow to change its opacity in the Fill and Stroke dialogue box.

Export and save

The icon is now ready, and you can export it as PNG via the File > Export Bitmap (Shift + Ctrl + E) option. Set the Export area to Page and select Browse to define the saving directory and name of your Series 40 full touch launcher icon. Press Export and close the Export Bitmap dialogue. You should also save the Inkscape SVG, in case you want to edit the icon later on.

Note: The final PNG icon size should not exceed 30 kb. If your launcher icon is bigger, delete unnecessary details and anchor points/nodes.
