Technical note

How HPG and DDS differ in practice

HPG describes geometry rather than pixels, so it has no inherent resolution. The conversion renders it at whatever size you choose, and that choice is final: enlarging the DDS afterwards will not recover the sharpness. Set the output dimensions or DPI before converting, not after.

FAQ

HPG to DDS Conversion

What are HPG files?

HPG is a vector image format created in a standard programming language called HPGL (Hewlett-Packard graphics language). Other extensions created in this language include PLT, HP2 and PL2. All are called "plotter files" and are created by drawing programs such as AutoCAD to be printed using a device specialized in vector graphics. An HPG file uses a line series of two-letter codes to render an image and can also include parameters.

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. The DDS format was first associated with Microsoft's DirectX 7.0 and later on with DirectDraw, a tool for accelerating the rendering of graphics in various applications. DDS is a container file and can be decompressed using a graphics processing unit (GPU).
