Hi all,
I implemented the following method in ft2font.cpp, and although it
works I don't know if it does the *right thing*.
char FT2Font::draw_rect_filled__doc__[] =
"draw_rect_filled(x0, y0, x1, y1)\n"
"\n"
"Draw a filled rect to the image. It is your responsibility to set the\n"
"dimensions of the image, eg, with set_bitmap_size\n"
"\n"
;
Py::Object
FT2Font::draw_rect_filled(const Py::Tuple & args) {
_VERBOSE("FT2Font::draw_rect_filled");
args.verify_length(4);
long x0 = Py::Int(args[0]);
long y0 = Py::Int(args[1]);
long x1 = Py::Int(args[2]);
long y1 = Py::Int(args[3]);
FT_Int iwidth = (FT_Int)image.width;
FT_Int iheight = (FT_Int)image.height;
if ( x0<0 || y0<0 || x1<0 || y1<0 ||
x0>iwidth || x1>iwidth ||
y0>iheight || y1>iheight )
throw Py::ValueError("Rect coords outside image bounds");
for (long j=y0; j<y1; ++j) {
for (long i=x0; i<x1+1; ++i) {
image.buffer[i + j*iwidth] = 255;
}
}
return Py::Object();
}
Basically, I copied the existing draw_rect method and changed the code
a bit. The above code draws a filled rectangle in the image buffer. I
use it mathtext for drawing a line (for a fraction etc.). What I'm
interested is the for loop:
for (long j=y0; j<y1; ++j) {
for (long i=x0; i<x1+1; ++i) {
image.buffer[i + j*iwidth] = 255;
}
}
I'm not sure that this is the right code - probably some pixel isn't
getting drawn. Anyone has some ideas?
Thanks,
Edin
