Hello everybody,
I have a GdkPixmap with some text. Now I want to print
it on GnomePrintContext by scaling it down.
I am creating a GdkPixbuf from the pixmap and scaling
the pixmap and printing it,
but It is loosing quality. If I use the GdkPixbuf
scaling the output on the GnomePrintContext becomes
blur
If I use the gnome-print scaling function It loosing
quality the fallowing code shows what I am doing
can anybody help me ?
void PrintStretchedText ( GnomePrintContext * context,
GdkPixmap *pixmap, int xSrc, int ySrc, int widthSrc,
int heightSrc, int widthDest, int heightDest )
{
GdkPixbuf pbsrc, pbscaled;
pbsrc = gdk_pixbuf_get_from_drawable ( NULL, src,
cmap, xSrc, ySrc, 0, 0, widthSrc, heightSrc );
pbscaled = gdk_pixbuf_scale_simple ( pbsrc,
widthDest, heightDest, GDK_INTERP_HYPER );
gnome_print_gsave ( context );
gnome_print_translate ( context, xDest, yDest );
gnome_print_scale ( context, widthDest, heightDest
);
gnome_print_pixbuf ( context, pbscaled );
gdk_pixbuf_unref ( pbsrc );
gdk_pixbuf_unref ( pbscaled );
}
Thanks in advance,
Regards
