From 038df5cdc99c53530f52f7c0755bd64c473908b0 Mon Sep 17 00:00:00 2001 From: Eric Linenberg Date: Mon, 16 Sep 2002 03:18:49 +0000 Subject: Daniel, The following patch makes loadable fonts actually work (finally!). It took me quite a while, but I finally figured out why the sim worked and the target didn't: the SH1 processor won't read longwords from a shortword alignment... I had to rev the .fnt file to version 1.1 (requires remaking *.fnt files) in order to fix this. Please apply the following patch completely. It's diffed against the latest CVS. I've also attached rockbox-fonts-1.1.tar.gz which includes known working *.fnt files, including a courB08 system.fnt, for demonstration. Now the real work can begin... Although the new system.fnt will work fine, if you try going to a really big font (try copying courB14.fnt to system.fnt), then you will find that it comes up and works in tree mode, but will crash the system when going into WPS mode... I'm sure this is because of the low-level lcd_bitmap not clipping properly when given a too-large bitmap, which the characters become. I haven't yet tried to debug the low-level driver. Of course, it all works on the sim... So the apps developers will now have to make sure that all apps screen sizes may vary according to the loaded font. The font height can be gotten through the lcd_getfontsize API. Files patched in fonts-6.patch 1. apps/menu.c - LCD_PROPFONTS error (2nd resubmission on this, please checkin) 2. firmware/font.c - fixes and reformatting. Please check this in as is, my vi editor requires more reformatting changes since I left tabs in the file, these are removed now (2nd resubmission on this, please checkin) 3. firmware/fonts.h - doc change on .fnt file format, .fnt version number incremented. 4. firmware/loadfont.c - fixes to load font properly, typedefs removed. 5. firmware/system.c - lcd_setfont(FONT_SYSFIXED) before issuing error, otherwise font may not exist. 6. tools/bdf2c - fixes for correct output when filename starts with a number, as well as when no DEFAULT_CHAR in .bdf file. (2nd resubmission on this, please checkin) 7. tools/writerbf.c - fixes for bugfixed fontfile format. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@2294 a1c6a512-1295-4272-9138-f99709370657 --- apps/menu.c | 4 ++-- firmware/font.c | 38 ++++++++++++++++++++++---------------- firmware/font.h | 7 +++++-- firmware/loadfont.c | 28 +++++++++++++++++++--------- firmware/system.c | 4 +++- tools/bdf2c | 19 +++++++++++-------- tools/writerbf.c | 5 +++++ 7 files changed, 67 insertions(+), 38 deletions(-) diff --git a/apps/menu.c b/apps/menu.c index dd5b9ba1e8..a42929ccf5 100644 --- a/apps/menu.c +++ b/apps/menu.c @@ -125,7 +125,7 @@ void put_cursorxy(int x, int y, bool on) static void menu_draw(int m) { int i = 0; -#if LCD_PROPFONTS +#ifdef HAVE_LCD_BITMAP int fw, fh; int menu_lines; lcd_getfontsize(FONT_UI, &fw, &fh); @@ -175,7 +175,7 @@ static void menu_draw(int m) static void put_cursor(int m, int target) { bool do_update = true; -#if LCD_PROPFONTS +#ifdef HAVE_LCD_BITMAP int fw, fh; int menu_lines; lcd_getfontsize(FONT_UI, &fw, &fh); diff --git a/firmware/font.c b/firmware/font.c index 5237f7d2aa..e9c70cd64e 100644 --- a/firmware/font.c +++ b/firmware/font.c @@ -83,6 +83,8 @@ getfont(int font) { PMWCFONT pf; + if (font >= MAXFONTS) + font = 0; while (1) { pf = sysfonts[font].pf; if (pf && pf->height) @@ -115,13 +117,13 @@ lcd_getstringsize(unsigned char *str, int font, int *w, int *h) int width = 0; while((ch = *str++)) { - /* check input range*/ - if (ch < pf->firstchar || ch >= pf->firstchar+pf->size) - ch = pf->defaultchar; - ch -= pf->firstchar; + /* check input range*/ + if (ch < pf->firstchar || ch >= pf->firstchar+pf->size) + ch = pf->defaultchar; + ch -= pf->firstchar; - /* get proportional width and glyph bits*/ - width += pf->width? pf->width[ch]: pf->maxwidth; + /* get proportional width and glyph bits*/ + width += pf->width? pf->width[ch]: pf->maxwidth; } *w = width; *h = pf->height; @@ -150,7 +152,11 @@ lcd_putsxy(int x, int y, unsigned char *str, int font) /* get proportional width and glyph bits*/ width = pf->width? pf->width[ch]: pf->maxwidth; - if(x + width > LCD_WIDTH) + if (x + width > LCD_WIDTH) + break; + + /* no partial-height drawing for now...*/ + if (y + pf->height > LCD_HEIGHT) break; bits = pf->bits + (pf->offset? pf->offset[ch]: (pf->height * ch)); @@ -224,29 +230,29 @@ rotleft(unsigned char *dst, MWIMAGEBITS *src, unsigned int width, MWIMAGEBITS srcmap; /* current src input bit*/ MWIMAGEBITS dstmap; /* current dst output bit*/ - /* calc src input bit*/ - srcmap = 1 << (sizeof(MWIMAGEBITS)*8-1); + /* calc src input bit*/ + srcmap = 1 << (sizeof(MWIMAGEBITS)*8-1); - /* calc dst output bit*/ + /* calc dst output bit*/ if (i>0 && (i%8==0)) { ++dst_col; dst_shift = 0; } dstmap = 1 << dst_shift++; - /* for each input column...*/ + /* for each input column...*/ for(j=0; j < width; j++) { - /* calc input bitmask*/ + /* calc input bitmask*/ MWIMAGEBITS bit = srcmap >> j; if (bit==0) { srcmap = 1 << (sizeof(MWIMAGEBITS)*8-1); bit = srcmap >> (j % 16); } - /* if set in input, set in rotated output*/ - if (bit & src[i]) { - /* input column j becomes output row*/ + /* if set in input, set in rotated output*/ + if (bit & src[i]) { + /* input column j becomes output row*/ dst[j*dst_linelen + dst_col] |= dstmap; } /*debugf((bit & src[i])?
