Strange vertical offset between normal and bold font
I'm currently continuing developing my puzzle collection, and I ran into a strange problem.
The example below is a 2x2 grid of the 'solo' (sudoku clone) puzzle. I want to draw the given fixed clue numbers in bold, and the user filled numbers in normal font. Worked so far, but the different fonts are drawn with a strange and annoying vertical offset to each other. See the attachment, where I draw red lines to illustrate the problem. Horizontally both are aligned correctly. I handle bold and normal fonts in completely the same way for drawing, only difference is I load "LiberationSans" or "LiberationSans-Bold". The characters themselves are drawn all in the same height, both Bold and Normal. This is the text drawing function: Code:
void ink_draw_text(void *handle, int x, int y, int fonttype, int fontsize, int align, int colour, const char *text) { ifont *tempfont; int sw, sh, flags; bool is_bold = (fonttype == FONT_FIXED) || (fonttype == FONT_VARIABLE); bool is_mono = (fonttype == FONT_FIXED) || (fonttype == FONT_FIXED_NORMAL); tempfont = OpenFont( is_mono && is_bold ? "LiberationMono-Bold" : is_bold ? "LiberationSans-Bold" : is_mono ? "LiberationMono" : "LiberationSans", fontsize, 0); flags = 0x000; if (align & ALIGN_VNORMAL) flags |= VALIGN_TOP; if (align & ALIGN_VCENTRE) flags |= VALIGN_MIDDLE; if (align & ALIGN_HLEFT) flags |= ALIGN_LEFT; if (align & ALIGN_HCENTRE) flags |= ALIGN_CENTER; if (align & ALIGN_HRIGHT) flags |= ALIGN_RIGHT; SetFont(tempfont, convertColor(colour)); sw = StringWidth(text); sh = TextRectHeight(sw, text, flags); if (align & ALIGN_VNORMAL) y -= sh; else if (align & ALIGN_VCENTRE) y -= sh/2; if (align & ALIGN_HCENTRE) x -= sw/2; else if (align & ALIGN_HRIGHT) x -= sw; DrawString(fe->xoffset + x, fe->yoffset + y, text); CloseFont(tempfont); } Any clue what I am doing wrong? |

I would assume it's the font's fault.
Did you try other fonts? |
