To earn free-of-charge registration you can make your own skin.
Here is information about skin creation.

All skins are in \Program Files\GogoL\skins\ directory and include two files:
skin_name.ski and skin_name.png (for example Base.ski and Base.png)

Example of Base.png:


Magenta color on the image shows transparent points (this color should differ from all colors on the skin).
Skin creation can be made in any graphics editor (for example in Photoshop or 3D Studio).

File with .ski-extension stores information about the skin and buttons/sliders arrangement.
Example of Base.ski:

This file you can edit with NOTEPAD

skinfile - link to a skin image file
transcolor - transparent color

In each section you can see the next values:
w - Image width (in pixels)
h - Image height (in pixels)
xsrc - Leftmost image cordinate on the source PNG-picture
ysrc - Topmost image cordinate on the source PNG-picture
xdest - Leftmost image cordinate related to the left-top corner of the main window
ydest - Topmost image cordinate related to the left-top corner of the main window
In some cases src-values can be identical to dest-values.

Section [main] defines main window. No xdest and ydest definitions are needed. It is recommended to use (0,0) position for source-coordinates.
Sections [close], [about], [presets], [options], [power_on], [power_off] are used to define buttons. If you don't want to define some button set all src- and dest- positions to -1000.
Section [slider] defines slider image. No xdest and ydest definitions are needed.
Four sections [slider_pos1], [slider_pos2], [slider_pos3], [slider_pos4] are used to define starting (xsrc,ysrc) and ending (xdest,ydest) positions within the main window. Slider movement can be vertical or horizontal only.

Here is some notes to skin creation:

1) To calculate transcolor you must use next formula: (Red*256+Green)*256+Blue, where Red,Green and Blue within the limits of [0..255]
2) For main-section w must be divisible by 4
3) If you don't want to use transcolor simply set it to -1
4) Transparent color should not be mixed with other colors.


After the file creation launch the program and choose created skin through the main menu.

After the successful testing of the skin send this file with RegKey and information about yourself to the technical support team. Then you will receive a license file.
