Hello all,
I have some invisible characters in a string to use them as marker and in a
specific configuration of size of characters and window I get an assert when
GrText() is called.
Example:
Char* MyString="A\nB";
Font proportional 1st character description=0x20 width of A=12pixels
width of B=12pixels
Window width= 24pixels
Nano-X V0.92
When GrText() is called, linear8_drawpixel() aborts with
User assertion failed: "x >= 0 && x < psd->xres", at fblin8.c:55
I think it is due to the test in gen_gettextsize() which is not similar to the
test in gen_gettextbits() in genfont.c
gen_gettextsize() assumes the size of char '\n' = 0pixel
but gen_gettextbits() assumes char '\n' =1st char = SPACE
I did this modification in gen_gettextsize() of genfont.c
- if(c >= pf->firstchar && c < pf->firstchar+pf->size)
width += pf->width[c - pf->firstchar];
+ /* if char not in font, map to first character by default*/
+ if(c < pf->firstchar || c >= pf->firstchar+pf->size)
+ c = pf->firstchar;
width += pf->width[c - pf->firstchar];
Regards,
Guy
