FAQ

GTL to DDS Conversion

What are GTL files?

The GTL extension is part of the Gerber group of formats, used as a standard in the fabrication of printed circuit boards (PCB). Gerber files contain 2D vector images that describe different data connected to PCB production, such as copper layers, solder masks, drilling or milling info. GTL files are created using Protel, a popular software for PCB layout design, and they describe the top copper layer.

What are DDS files?

DDS (DirectDraw Surface) is an image file format that usually contains texture data, cubic environment maps or other type of data compressed using the S3TC (S3 Texture Compression) algorithm.
