Hi All,
I tried rendering smth to enhanced windows metafile. The result looks strange.
Two files attached are results of rendering the code:
void TestCairoEMF (bool emf)
{
HDC hdc;
cairo_surface_t *surface;
cairo_t *cr;
if (emf)
{
hdc = CreateEnhMetaFile(NULL, "test.emf", NULL, NULL);
surface = cairo_win32_surface_create(hdc);
}
else
surface = cairo_pdf_surface_create("test.pdf", 100, 30);
cr = cairo_create (surface);
cairo_select_font_face (cr, "Sans", CAIRO_FONT_SLANT_NORMAL, CAIRO_FONT_WEIGHT_NORMAL);
cairo_move_to(cr, 5, 5);
cairo_line_to(cr, 30, 25);
cairo_line_to(cr, 50, 10);
cairo_line_to(cr, 80, 20);
cairo_set_source_rgb(cr, 0, 0, 1);
cairo_stroke(cr);
cairo_move_to(cr, 15, 15);
cairo_set_font_size(cr, 15);
cairo_set_source_rgb(cr, 0, 0, 0);
cairo_show_text(cr, "hello world");
if (emf)
CloseEnhMetaFile(hdc);
cairo_destroy (cr);
cairo_surface_destroy (surface);
}
However, if I use regular win32 DC, it works fine.
Am I doing smth wrong?
Or Windows metafile rendering is not supported at all?
Thanks in advance,
Mikhail.
