As per my understanding there is no jpeg image decoder in cairo. only png surfaces were supported.<div>-vicky <div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> Message: 1 Date: Thu, 5 Jan 2012 18:35:51 -0800 From: Jeffrey Britton <<a href="mailto:jeffb0098@gmail.com">jeffb0098@gmail.com</a>> Subject: [cairo] Trouble displaying a jpeg image To: <a href="mailto:cairo@cairographics.org">cairo@cairographics.org</a> Message-ID: <<a href="mailto:CAJTKU_h6YF6e-5uG_VP5PgdTaryxmT6zvKaKiLe54cDuGvy9hg@mail.gmail.com">CAJTKU_h6YF6e-5uG_VP5PgdTaryxmT6zvKaKiLe54cDuGvy9hg@mail.gmail.com</a>> Content-Type: text/plain; charset="iso-8859-1" I am trying to read a jpg from file and display it. I am using Python with pyCairo. I have the following code that works with some help from PIL, but it is slow. I feel that there must be a more direct route. There is an example at this link: <a href="http://cairographics.org/pythoncairopil/" target="_blank">http://cairographics.org/pythoncairopil/</a> but it does not work. img = Image.open('image.jpg') # The next 3 lines are to get the data to pass to Image.frombuffer # I need to convert rgb to bgra. l = [struct.pack('BBBB', b, g, r, 0xFF) for (r,g,b) in img.getdata()] # runs over whole image to convert to string s = string.join(l, '') # runs over whole image again to get a writable buffer data = array.array('B', s) im1 = Image.frombuffer("RGBA", img.size, data, "raw", "RGBA", 0, 1) # runs over whole image twice self.img = array.array('B', im1.tostring()) stride = cairo.ImageSurface.format_stride_for_width(cairo.FORMAT_ARGB32, self.width()) self.img_surface = cairo.ImageSurface.create_for_data (self.img, cairo.FORMAT_ARGB32, self.width(), self.height(), stride) Yikes that is bad. Once I have the surface, then I do ctx.set_source_surface(surface, self.x, self.y) make_rectangle_path(ctx, self.x, self.y, self.width(), self.height()) ctx.fill() Help! -------------- next part -------------- An HTML attachment was scrubbed...
