* dnsize() works like dsize() but a limit on the number of bytes is
specified. This is useful to obtain the length of a substring.
* drsize() has a reverse limit; the input specifies a number of pixels
and the function determines how much of the input fits. This is useful
for word wrapping algorithms.
This parameter controls the maximum number of glyphs to print.
For backwards compatibility, it is automatically inserted by a macro in
older calls with only 7 parameters.
This commit introduces custom character spacing with a new fxconv
parameter "char-spacing". Word spacing is also tied to the width of the
space character (0x20). This removes the need for special semantics on
the space character, but requires that its size be specified with gray
pixels for proportional fonts.
This also fixes problems with the size of spaces in dsize() not being
correlated with their size during rendering, since on fx-9860G topti
already used the glyph's with as word spacing.
Since fxconv changes but gint's Makefile does not track updates to
external tools, a full rebuild of gint is required past this commit.
This change modifies the font_t type to replace the concept of charset
with a more generic list of non-overlapping Unicode blocks defined by a
starting code point and a size.
It also takes advantage of the assembly feature of fxconv, introduced
for libimg long after the first version of topti, to support pointers in
the converted structure rather than having to tediously compute offsets
within a variable-size structure.
* Define dgray() to replace gray_start() and gray_stop()
* Introduce a mechanism to override the d*() functions rather than using
another set of functions, namely g*(). Gray rendering should now be
done with d*() (a compatibility macro for g*() is available until v2.1).
* Gray engine now reserves TMU0 at the start of the add-in to prevent
surprises if timers are exhausted, so it nevers fails to start
* Replace other gray engine functions with dgray_*()
* More general rendering functions (in render/) to lessen the burden of
porting them to the gray engine. As a consequence, dtext_opt(),
dprint_opt() and drect_border() are now available in the gray engine,
which was an omission from 230b796.
* Allow C_NONE in more functions, mainly on fx-CG 50
* Remove the now-unused dupdate_noint()
This change introduces two new functions dtext_opt() and dprint_opt()
that have both color and alignment options. The regular dtext() and
dprint() have been changed to always used bg=C_NONE which is what most
calls want.
Behave like Basic's Horizontal and Vertical commands. Internal dline()
optimizations are renamed gint_dhline() and gint_dvline().
Also supports ghline() and gvline() in the gray engine.
Optimization cases here are amost negligible due to limiting RAM access
frequencies and the very limited amount of work accomplished in the
functions. Code maintainability is prioritized by using dline().
This change introduces exception handlers that default to a fatal error
with an on-screen description of the exception and some debugging
information.
It also adds the dprint() function as a definitely-needed helper and
removes bootlog_unmapped() by using the exception handler for the fatal
error display. (Also printf() is now required in all gint add-ins; this
is sad, but space is not as much of a constraint as debugging.)
Finally, the exception handler is used to handle an interrupt which is
an exception in practice, the DMA address error. On fx-CG 50, additional
DMA-related information is displayed on the screen. This is left out on
fx-9860G as there is not enough space.
This commit introduces bopti for fxcg50 with the first basic 16-bit
formats. The performance is rather slow, especially for large images,
and will need refinements and/or overclock to be really efficient in
full-screen real-time applications.
* Now uses topti instead of fxlib for text (including MMU failure)
* Fit .pretext into 4k for everything before MMU succeeds
* A short version of sprintf() for dynamic messages
* Support a driver function, status(), to allow early driver debug
* Expose more useful platform information in <gint/mpu.h>
* Expose the first of a few CASIOWIN syscalls
