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.
* Specify a line height for the default fx-CG 50 font so that the height
returned by dsize() is correctly 9, not 11.
* Adjust vertical and horizontal alignment in dtext_opt() and
dprint_opt() by a full pixel (DTEXT_BOTTOM, DTEXT_RIGHT) and half a
pixel (DTEXT_MIDDLE, DTEXT_CENTER) to make sure that the specified
position is within rendered text (as in DTEXT_LEFT and TEXT_TOP) and
to improve centering of strings with odd width or odd height, for
which there is only one valid position.
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.
* Turn on GCC's -O3 for bopti files
* Remove the bopti_render_noclip() step
* Use rbox as early as possible to avoid moving memory around
* A lot of local grinding
* Defined the single-column single-position (SCSP) situation where a
single column of the input is blit on a single position of the VRAM.
Provided optimized assembly and a specialized bopti_render_scsp()
function.
* Improved the rendered by reducing the amount of computation and
clarifying the semantics of the rbox.
* Separated rbox setup from clipping by making bopti_render_clip() a
purely abstract superset of bopti_render_noclip().
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()
Since both platforms now have their VBR and gint-specific data loaded
along the add-in's data, the .gint.data section is entirely unused.
The .gint.bss section is still used for uninitialized objects (it has
different semantics than .bss which is initially cleared) and the
.gint.data.sh3 and .gint.bss.sh3 sections that are dropped on the
SH4-only fx-CG 50 are also still used.
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.
This change adds a TLB miss handler that calls __TLB_LoadPTEH() and
removes the startu mapping of add-in pages in the explore() routine of
src/core/start.c.
Note that calling __TLB_LoadPTEH() manually might unexpectedly lead to a
TLB multihit problem as the requested page might be accidentally loaded
by a TLB miss in the code that loads it. A TLB multihit is a platform
reset, so this function should always be considered unsafe to call
(unless the calling code is in a combination of P1 space and ILRAM).
This change also moves a lot of functions out of the .pretext section,
notably topti, as this was designed to allow panic messages when the
add-in couldn't be mapped entirely. By contrast, a GMAPPED macro has
been defined to mark crucial kernel code and data that must remain
mapped at all times. This currently puts the data in ILRAM because
static RAM is not executable. An alternative will have to be found for
SH3-based fx9860g machines.
This version still does not allow TLB misses in timer callbacks and
breaks return-to-menu in a severe way! It is not suitable for any
stable application!
This macro used to protect the declaration of the [vram] variable of
gint. This variable was short to keep drawing functions short but could
clutter the namespace.
That being said, it's even better to just [#define vram gint_vram] if
you need. This change renames the variable to [gint_vram], exposes it
whenever <gint/display.h> is included, and removes the GINT_NEED_VRAM
macro altogether.
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 finally introduces gray image rendering with bopti. This
is the final iteration of bopti v2 and certainly the fastest so far.
All four profiles are supported, without change to the format.
Light and dark were erroneously swapped in my documentation's
formulae, but not in the way operands were cancelled when x=0,
leading to strange results.
* 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
