Version 0.4:
* New features:
* Support for image types (color models):
GREY, GREYA, RGB, RGBA, CMY, CMYK, CMYKA
and custom
* Additional builtin energy functions based on
luma instead of brightness
* Support for custom energy functions
* Functions to read out the energy map
* Cancel function to interrupt computations
* Additional methods for bias and rigidity masks
* Use a single progress instead of several
ones when the update is performed in steps
* Can handle input buffers non-destructively
* Performace related:
* Faster rescaling thanks to optimisations in
the code
* Spare memory when not using features (e.g. the
bias)
* Configuration
* The default installation directory is now /usr
instead of /usr/local
* Compiling under MinGW now correctly produces a
DLL with the default settings
* Now it also compiles under MS Visual C++
* All public macro names start with LQR_* (old
versions are still available but can be disabled
at configure time)
Version 0.3:
* New features:
* Enlargement is not limited to 200% any more
(it is automatically performed in steps)
* Added readout functions for the internal
visibility map
Version 0.2:
* New fetures:
* Support for 16-bit, 32-bit and 64-bit
per channel images
* Rigidity masks
* Left-right/top-bottom balance
* Performace related:
* Improved attached visibility maps
management (lower memory requirements)
* All internal buffers turned from
double to float, improving both speed
and memory requirements
* Documentation:
* Reviewed manual and completed refence
* Added man pages
This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.
