Hello sir,

I am seeing the same probalem, but infortunately Django does not reveal anymeaningful information for debugging. What is the fix for this issue? Unfortunately I am using django models and I am seeing similar error with a differnt field. I am able to save the data to db but I am having problem when rendering. I cannot even see the logged values in script. What is the solution, pls help?

This works fine for me when you have only one curve.

private List FindPointsForBounds(Point P0, Point P1, Point P2, Point P3)
{
List toReturn = new List();

int A = P3.X - 3 * P2.X + 3 * P1.X - P0.X;
int B = 3 * P2.X - 6 * P1.X + 3 * P0.X;
int C = 3 * P1.X - 3 * P0.X;
int D = P0.X;

int E = P3.Y - 3 * P2.Y + 3 * P1.Y - P0.Y;
int F = 3 * P2.Y - 6 * P1.Y + 3 * P0.Y;
int G = 3 * P1.Y - 3 * P0.Y;
int H = P0.Y;

float x, y;
float xMin = int.MaxValue;
float yMin = int.MaxValue;
float xMax = 0;
float yMax = 0;

for (float t = 0.0f; t <= 1.0f; t += 0.01f)
{
x = A * t * t * t + B * t * t + C * t + D;
if (x < xMin)
xMin = x;
if (x > xMax)
xMax = x;
y = E * t * t * t + F * t * t + G * t + H;
if (y < yMin)
yMin = y;
if (y > yMax)
yMax = y;
}
toReturn.Add(new Point((int)xMin, (int)yMin));
toReturn.Add(new Point((int)xMax, (int)yMax));
return toReturn;
}

Beautiful pics, maybe you need more work on the composition.
I might deduce from the pics that you are a big food lover ^^

Hi MiCHiLU,

I've been there by short trip with my wife about seven years ago! Thank you for uploading the several pictures of Sri-Lanca and nice diaries about your travel. There were a lot of beautiful places and the people living in the country were very kind to Japanese travelers.
I'm looking back on the place with nostalgia.

I want to go there again someday.

This is not recommended to modify main.py. See discussion at

http://groups.google.com/group/django-non-relational/browse_thread/thread/d46e7ef843cdf944

If some handlers modify sys.path the root must be inserted in the beginning:

sys.path.insert(0, root)

this is cool..

2010-07-28T17:46:31.507+09:00

Almost same:

for c in curves:
P1, P2, P3 = (
(c[0], c[1]),
(c[2], c[3]),
(c[4], c[5]))

here, any c in curves are [handler, handler, point]
P0 and P3 are terminal points of each bezier curves.

i couldn't understand the source code , could you please comment it ? ,
or give some explanation of the mathematical solution,
i'm making graphics application using python and i need this

my curve has the structure : [point,point,point....]

point = [handler,vertex,handler]

could you help me ?

That's it! Thank you for information!
