Unique Features
D-Type Font Engine is one of the very few font engines with direct support for Multiple-Master font technology.
D-Type's font hinting technology is elegant and simple yet advanced and powerful. The final result is extremely fast and high-quality text, whether it's on-screen or in print.
Unlike TrueType, our hinting technology does not require a significant number of delta hints that must be generated manually for different point sizes. Even better, good D-Type hints can be generated 100% automatically. As a result, non-hinted and poorly hinted TrueType fonts still look great when rendered by D-Type. This unique feature cannot be found in any other font technology available.
D-Type hints in combination with D-Type's excellent anti-aliasing features produce smooth and beautiful type, completely eliminating pixels and "jaggies". Text is smooth when rotated, but still crisp and legible when displayed at small sizes.
Memory management is excellent. It is possible to access fonts in several different ways. For example:
- the entire font is in memory (RAM)
- only frequently used characters are in RAM
- the entire font resides on disk; just pointers to individual glyphs are in RAM
The last option makes it possible to open hundreds of fonts at the same time even when the amount of memory is limited.
Bitmap Compression
Starting with D-Type Font Engine version 4.0.4.2, glyph images can be stored in the bitmap cache in a highly compact (compressed) format. This storage format is a proprietary D-Type compression format that is particularly well suited for 8-bpp grayscale bitmaps.
Bitmap compression is extremely fast and effective. When enabled, bitmaps will consume 3-10 times less space in the bitmap cache than non-compressed bitmaps. This is highly recommended when the size of the bitmap cache is small (e.g. in memory constrained environments).
Here is an example:
 |
|
A plain 8-bpp grayscale bitmap of the glyph "S". The dimensions of this bitmap are 84 x 108 pixels. Thus, this bitmap will consume 9072 bytes of storage space in the bitmap cache (if stored non-compressed).

 |
|
A representation of the compressed grayscale bitmap of the same glyph "S". This compressed bitmap will consume only 1395 bytes of storage space in the bitmap cache which is about 15% of the original non-compressed size. Thus, by using the bitmap compression we were able to reduce this bitmap's storage requirements by more than 6.5 times!
