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.
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.
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.
Since Memallox's newlib port is currently unstable, gint has to
provide some standard functions on its own. Instead of a single
<gint/std.h> header, this commit makes a gint/std directory containing
headers under standard names.
