printing gtktextview and text layout
Hi, In brasero I recently started to work on a WYSIWYG cover editor. I ran into a problem when I try to print something: the layout of the text is not exactly similar to what is displayed on screen. For example, if I make a line of a that goes from the left side to the right side and if I try to print this line, then in the preview and on the paper I have a shorter line of 'a' that starts at the right place but that ends before the point it should reach. On screen: | full line of x a | On paper: | smaller line of x a | For text editing I use a GtkTextView with WRAP_CHAR set. I allocate its space by using the screen resolution (with gdk_screen_get_resolution ()) multiplied by the width and height (in inch) of a CD cover. For printing, I use a PangoLayout (from gtk_print_context_create_pango_layout ()) with WRAP_CHAR as well. I get the sizes for the borders the same way (gtk_print_context_get_dpi_x * cover_width, ...). These latter border sizes were correct when I checked. Could someone help me with that please?
