George: What to use for fast 2D graphics?

Note that GDI+ is usually 4-8x slower than GDI. It might have a nicer API, handle alpha better, etc. but if you are looking for fast 2D graphics, than GDI is far superior to GDI+. You can take the measurements yourself.

WPFGuy: What to use for fast 2D graphics?

Perhaps it is because some time has passed and hardware has improved but on my sub $1000 laptop (Toshiba Satellite with Intel i7 @ 1.6GHz, NVIDIA GeForce 330M running under Win7-64) I am able to plot 10,000 lines in 55mS using a visual while still retaining access to hit testing and other WPF goodies.

WPF does have this "fun" attribute of being able to do everything a bunch of different ways - it is just a matter of trying to find the one that is "good enough."

I'd like to visit the Caratinga reserve, I'd love to talk to someone there to arrange this but..... No email, no phone contact etc etc. Will I really have to drive up on the off chance of being welcomed?
A bit more contact information would be very welcome !!!

I have noticed that down through all my reading of this amber led flashing problem on the net that not one person has used a multi meter to check the power supply for voltage . I would like to say that the only person that made any sense was Mr Pablo Fernicola in the above blog making it nice and simple . Now a multi meter is the most basic tool out there for helping to resolve problems have we forgotten the basics ???? . Pablo just did what made sense and did not go on and on with tecnical "wana be" stuff. From an old electronics expert in ireland well done Pablo.

Very useful information

Jim: WPF- Pick Your API Abstraction

jimbean@yahoo.com (Jim) — Mon, 20 Jul 2009 07:42:53 -0700

I noticed this:

1. Create a new solution/add new WPF Application project.
2. place just a canvas in the main window.
3. create a RotateTransform + PageUp/Down events for incrementing the angle with +-10.
4. place 50 polygons on the canvas
5. Press PageUp/Down (and keep pressed)

On my PC the CPU usage is 80%.

1. Now try placing 1000 polygons: the CPU can reach 100% at 1-2 frames/s.

I checked RenderCapability.Tier and it's 2 - meaning that it should render everything by hardware. But it's not working, why?

(Example code:
RotateTransform rotation = new RotateTransform();
TransformGroup tg = new TransformGroup();
tg.Children.Add(rotation);
Polygon polygon = new Polygon(); // then add 4 points
polygon.RenderTransform = tg; // repeat this for example 50~1000 times
canvas.Children.Add(polygon);)

I also tried forcing software rendering and it seems that the performance is the same.

Oscar Diaz: The Blinking Amber Light

I just got a Dell E510, blinking amber light of death, new PSU, check HDD, Memory, Processor, reseating every connector. Nothing.

Then, when I was starting to take it apart (to use the DVD drives on a new system) I notice that on one of the front USB ports had all four pins
twisted inside, it looked like if someone had twisted a memory stick inside the
port, cuz they were all twisted and touching eachother and touching the inner metal jacket of the port. As you may know, the on/off switch runs to
the motherboard with all the usb ports , earphones and mic jacks on a ribbon cable. So, when I disconnected the ribbon cable, I did not get the blinking amber ligth of death, istead I got the regular green light and the fans spinned for a sec. Since the power switch is not connected I could not turn the machine on. Then, I just tried to untwist the pins inside the port, making sure that they were not making contact with the inner metal part, and connected the ribbon cable to the motherboard, and what'd you know , the thing just turned on just like that!!!!
Every thing works now (with the exception of that USB port).

So there you have it, this is the least thing I could have checked.

It is useful to everyone.very good opinion.would be much easier for designers and translates them very easy to work.

Mathew Webber: When to use WPF and when to use other technologies

Mathewwebber@hotmail.com (Mathew Webber) — Fri, 09 Jan 2009 10:44:42 -0700

Are we any closer to invariant line thickness in WPF?

We really need the ability to turn of the scaling of stroke thickness on zoom within our application. We are current considering the removal of WPF altogether and going back to GDI+, which I would rather not do.

Any news?
