* include/freetype/freetype.h:
|

Added types and structures to support incremental typeface loading.

The FT_Incremental_Interface structure, defined in freetype.h,

is designed to be passed to FT_Open_Face to provide callback
|
||||
functions to obtain glyph recipes and metrics, for fonts like
|
||||
those passed from PostScript that do not necessarily provide
|
||||
all, or any, glyph information, when first opened.

The following environment variables control debugging output and

|

|

|

FT2_DEBUG
|

this variable is only used when FreeType is built with FT_DEBUG_LEVEL_TRACE
|

defined. It contains a list of component level definitions, following this
|

format:

definitions, following this format:
|

component1:level1 component2:level2 component3:level3 ...
|

where "componentX" is the name of a tracing component, as defined in
|
||||
"fttrace.h", but without the "trace_" prefix, and "levelX" is the
|
||||
"fttrace.h", but without the "trace_" prefix, and "levelX" is the
|
||||
corresponding level to use at runtime.
|
||||
|
||||
"any" is a special component name that will be interpreted as
|

"any/all components". For example, the following definitions

"any" is a special component name that will be interpreted as

|
||||
export FT2_DEBUG="any:2 memory:5 io:4" (on Linux)
|

both stipulate that all components should have level 2, except for the

respectively.

the memory and io components which will be set to trace levels 5 and

|
||||
|
||||
FT2_DEBUG_MEMORY
|
||||
this environment variable, when defined, tells FreeType to use a debugging
|
||||
memory manager that will track leaked memory blocks as well as other common
|
||||
errors like double frees. It is also capable of reporting _where_ the
|
||||
leaked blocks were allocated, which considerably saves time when
|
||||
debugging new additions to the library.
|
||||
|
||||
This code is only compiled when FreeType is built with the FT_DEBUG_MEMORY
|
||||
macro #defined in "ftoption.h" though, it will be ignored in other builds.

This environment variable, when defined, tells FreeType to use a
|
||||
debugging memory manager that will track leaked memory blocks as
|
||||
well as other common errors like double frees. It is also capable
|
||||
of reporting _where_ the leaked blocks were allocated, which
|
||||
considerably saves time when debugging new additions to the library.
|
||||
|
||||
This code is only compiled when FreeType is built with the
|
||||
FT_DEBUG_MEMORY macro #defined in "ftoption.h" though, it will be
|
||||
ignored in other builds.

Voila,
|
||||
|
||||
- David Turner
|
||||
|
||||
|
||||
|
||||
used like printf( format, ... ), but with double quotes. This will
|
||||
send a message to the standard error descriptor (stderr on most systems)
|
||||
in certain builds of the library
