I'd like to fill paths with different hatches. I'm using the code below to create a little part of the hatch and to repeat it to fill the path. The problem is that when I do it, there's a little space (a thin and transparent line) between each repeat. For example, if I want to repeat a completely black square (see the code below), it gives me this result : <a class="moz-txt-link-freetext" href="http://img96.imageshack.us/img96/8747/cairopblmcw6.png">http://img96.imageshack.us/img96/8747/cairopblmcw6.png</a> I expected it to draw a completely black area. If I draw a line or anything else instead of a black square, I get the same type of result. This result is displayed in the preview window of gtk printing (in fact in evince). Is there any way to suppress this line ? Thanks. The code : cairo_t * cr; cairo_surface_t *surface; surface = cairo_surface_create_similar(cairo_get_target(m_cairo),CAIRO_CONTENT_COLOR_ALPHA,5,5); cr = cairo_create(surface); cairo_set_line_cap(cr, CAIRO_LINE_CAP_SQUARE); cairo_set_line_width(cr, 1); cairo_set_antialias(cr, CAIRO_ANTIALIAS_NONE); cairo_set_source_rgba(cr, redPS, greenPS, bluePS, alphaPS); //these values give black color cairo_paint(cr); cairo_stroke (cr); cairo_destroy(cr); cairo_pattern_t * pattern = cairo_pattern_create_for_surface (surface); cairo_surface_destroy(surface); cairo_pattern_set_extend (pattern, CAIRO_EXTEND_REPEAT); cairo_set_source(m_cairo, pattern); //here i create a path in another cairo context (m_cairo) //and i fill it with the pattern: cairo_fill( m_cairo ); </body> </html>
