Smooth Draw 3 Free Download ((FULL))

As many people knew, HTML5 Canvas lineTo() is going to give you a very jaggy line at each corner. At this point, a more preferable solution would be to implement quadraticCurveTo(), which is a very great way to generate smooth drawing. However, I desire to create a smooth, yet accurate, draw on canvas HTML5. Quadratic curve approach works well in smoothing out the draw, but it does not go through all the sample points. In other word, when I try to draw a quick curve using quadratic curve, sometime the curve appears to be "corrected" by the application. Instead of following my drawing path, some of the segment is curved out of its original path to follow a quadratic curve.
My application is intended for a professional drawing on HTML5 canvas, so it is very crucial for the drawing to be both smooth and precise. I am not sure if I am asking for the impossible by trying to put HTML5 canvas on the same level as photoshop or any other painter applications (SAI, painterX, etc.)
Note: to get a professional result you will also need to implement moving average for short thresholds while using cardinal splines for larger thresholds and using knee values to break the lines at sharp corner so you don't smooth the entire line. I won't be addressing the moving average or knee here (nor taper) as these are outside the scope, but show a way to use cardinal spline.
A side note as well - the effect that the app seem to modify the line is in-avoidable as the smoothing happens post. There exists algorithms that smooth while you draw but they do not preserve knee values and the lines seem to "wobble" while you draw. It's a matter of preference I guess.
The segment (nos, or number-of-segments) is the resolution between each point. In most cases you will probably not need higher than 9-10. But on slower computers or where you draw fast higher values is needed.
Moving average is typically used for statistical purposes, but is very useful for drawing applications as well. When you have a cluster of many points with a short distance between them splines doesn't work very well. So here you can use MA to smooth the points.
I am trying to create a drawing area with canvas. I am having trouble with making the lines look smooth when drawing curves and I also have changing line thickness in my algorithm which looks bad as well because the size jumps to much as well and you can see where the size changed. I did find this link on stackoverflow but this was for a native iPhone app and I can't figure it out.
What I'm doing is starting a new list of points on mouseDown, then for each mousemove I add a point to the list. Once I get enough points (6 or so) I start drawing quadratic curves, with the control point of the curve being the average of the current point and the next point.

SmoothDraw is a great painting and drawing program that has a lot going for it, from its intuitive UI to its good set of tools, and support for layers. It does not have the most advanced features that professionals need, but it's not for those users, in the first place. Just manage your expectations, and you'll be surprised how much you can do with this application. Recommended.
I could not figure it out so I thought I will draw it in CorelDraw and import it to SketchUp as a vector format (like EPS, AI, etc) but it seems SketchUp does not support the import of 2D vector files. So I imported it as PNG image but now how to recreate the same line in SketchUp?
The nice thing about drawing circles and ellipses this way is that rather than just getting one shot at drawing a perfect shape, you actually get a bunch of chances. And then you get to pick out the best one!
To use this method, I like to hold the pencil with the Overhand grip. Let your hand hover over the drawing paper a bit so that it can move smoothly. You can lightly touch your pinkie and ring finger to the paper for stability.
Simple example: try to draw a picture on a wall of your room, using you wrist.
Even if you finish it, job will take huge time and pleasure from a picture will fall in this time which spent for work.

Through this thoughts, try to use the big canvas. A2 format (594420 mm), i think, is minimal for beginners.

Ok, I realized that all I actually need is:
ofSetLineWidth(10); in order for my segmentation program to recognize the lines.
They just needed to be a bit thicker so that they could be contoured properly, nevermind outputting it as an svg.
However what im wondering now is, can the lines be smoothed without the need to export it as a svg?
Is there a way of rendering it more graphically pleasing like the idea they show in the second picture of: ?
What getResampledBySpacing and getSmoothed would solve is a low amount of vertices in the polyline. So if your polyline looked like a Z with only 4 vertices, by resampling and smoothing you could make it look more like an flipped S with many more vertices.
