Hi Venito,
Firstly, I do not know the 'style' of the font you have depicted.
The effects used for the font is achievable with PI.
How did I do it, you may ask?
1. With the stamp tool, gems I created one particular round gem and made a stamp. I then created about 5 rows using the straight line tool. After the 5 lines were created I duplicated to the amount it would take for the large letter. You could save this as a background/fill.
2. In the EasyPalette, under Library there's a library heading: Text. There's a number of different style text you can use.
3. Open a blank canvas with say a dark brown colour. From the EP Library, Text, choose one, and double click it. This will be placed on your blank canvas. Right click the text and 'UNGROUP'.
4. Select the Pick Tool, and separate the images. You will see on the Attribute bar, the multi-fill, font name and size and also different dimensions for each set of text. This gives you an idea of how they are put together.
5. If you right click on the 'Colour' choose the Gradient Fill, you can change the colours of the OUTLINE of the text which is in 3D Pipe.
6. If you click on the Text Tool, you can type your own letters, and if it's the solid, 2D can fill it with the diamond fill made at the start.
Sometimes you can't fill as it requires 24bit True Colour, but there's always a way around. Open the 'diamond fill' in your workspace and place the letter(s) on it and make sure the letter is to the front. You can then erase the surplus.
Also, you can right click and convert to image, then fill.
There's endless possibilities, it's mostly a matter of trial and error, but whatever PS or PSP can do, you can bet PhotoImpact can do equally as well.
