gtk pango draw rotated text
Hi, I want to draw some rotated text on a Window. I've tried every code I found on the net but still no solution :( I would like to draw some rotated text on a window, the rotation point should X,Y and not to the center of the rectangle where the text is draw. Can anyone please help me? This is my current code (in pascal): WidgetCont := pango_layout_get_context(UseFont); rotated_matrix.xx := 1.0; rotated_matrix.xy := 0.0; rotated_matrix.yx := 0.0; rotated_matrix.yy := 1.0; rotated_matrix.x0 := 0.0; rotated_matrix.y0 := 0.0; pango_matrix_rotate (@rotated_matrix, 45); pango_context_set_matrix (WidgetCont, @rotated_matrix); pango_layout_context_changed (UseFont); gdk_draw_layout_with_colors(DevCtx.drawable, DevCtx.GC, X, Y, UseFont, Foreground, nil); Thanks in advance.
