Terral Text Settings
Solid noise Choosing Solid noise will render the text using soft solid noise shapes.
Choosing current picture, on the other hand, will render the bumpmap onto the
current layer.
Font name The Font name button selects the font that will be rendered by the filter.
Choosing an appropriate font size is important. Too small, and the text string may
be unreadable, too large, and the string may take hours to render.
Text The Text input box is where the text string that will be rendered can be input.
Blur amount Blur amount is a slider setting for the amount of blur to use prior to bump
mapping the text. A high setting here usually leads to more rounded text, but it
is best to test various settings based on the result required, the font, and the font
size.

13.149 TGA
Overview
The TGA format was developed by Truevision as a way of storing color images,
specifically 24 and 32-bit color images. The format is sometimes known incorrectly
as “Targa” which refers to the graphics hardware for which the format was originally
designed.
The TGA format is lossless (no image data is discarded during saving) and supports
high-color images.
The TGA format can be RLE (Run Length Encoding) compressed which results
in significantly smaller file sizes, but will give slower performance when handling the
image.
