ftbench
|
||||
========
|
||||
|
||||
ftbench is a program designed to run FreeType benchmarks. It accepts various options and a font name to run specific tests on font rendering operations.
|
||||
|
||||
Each test may involve tasks such as:
|
||||
|
||||
. Initializing the library
|
||||
. Opening the font file
|
||||
. Loading and optionally rendering each glyph
|
||||
. Comparing results with cached versions (if available)
|
||||
. Configuring specific charmap indices, load flags, etc.
|
||||
|
||||
Usage is time-limited or can be explicitly set to use a maximum number of iterations per test.
|
||||
|
||||
|
||||
Command line options
|
||||
--------------------
|
||||
|
||||
-C Compare with cached version (if available).
|
||||
-c N Use at most N iterations for each test (0 means time-limited).
|
||||
-e E Set specific charmap index E.
|
||||
-f L Use hex number L as load flags (see FT_LOAD_XXX'). -H NAME Use PS hinting engine NAME (default is adobe').
|
||||
-I VER Use TT interpreter version VER (default is version 40).
|
||||
-i I-J Forward or reverse range of glyph indices to use.
|
||||
-l N Set LCD filter to N (default is 0: none).
|
||||
-m M Set maximum cache size to M KiByte (default is 1024).
|
||||
-p Preload font file in memory.
|
||||
-r N Set render mode to N (default is 0: normal).
|
||||
-s S Use S ppem as face size (default is 10ppem).
|
||||
-t T Use at most T seconds per bench (default is 2).
|
||||
-w N Use N iterations for warming up before each test.
|
||||
|
||||
-b tests Perform chosen tests (default is all).
|
||||
-v Show version.
|
||||
|
||||
Compilation
|
||||
-----------
|
||||
|
||||
make baseline To create a baseline for your benchmarks, use the `make baseline` command. This will compile the ftbench.c and create a set of baseline measurements in the objs/baseline/ directory.
|
||||
|
||||
make benchmark To run the benchmarks, use the `make benchmark` command. The results will be stored in the objs/benchmark/ directory. It will copy tohtml.py script to objs/ and generate a html file.
|
||||
|
||||
make clean-benchmark To remove all generated benchmark files and clean the objs directory, use the `make clean-benchmark` command.
