TabItem | 2, Things You Should Know About WPF
A canvas works on absolute positions so shouldn't be used for any relative layouts. However there are several options available in the WPF framework. the one. TextBlock Text = "Augustus" HorizontalAlignment = "Center" /> < TextBlock Text = "Augustus stuff goes.

Then I put a rectangle around the center using the new coordinates. Depending on the hierarchy of how you draw your items relative to each other.
Then I put a rectangle around the center using the new coordinates. But the rectangle was placed way out from the center, because the new 0-point was also scaled away.
How to: Scale an Element
Is that a current problem, or a problem when trying to use PageScale? Depending on the hierarchy of how you draw your items relative to each other will affect the approach you take to do your drawing.Create a Column Chart Showing Percentages
Generally I would move the 0,0 point to the middle of the drawing area first, as an independent operation. Then I would draw the grid with that assumption drawing lines over a negative to positive range.
And then draw rectangles. You would not want to include translation as part of the drawing of the rectangle itself, unless you are using that to position where the rectangle would be drawn.
In that case, you would want to save the current state of the drawing context i. After you draw, you would restore the context you were given so that the next item to draw starts with 0,0 where 0,0 should be. Here's just one way the two centered drawing of the same rectangle structure could be done. Note the use of two pens of different sizes to compensate for the scaling. The lines drawn with a pen will get "fatter" as you scale the drawing up.

If you create a pen with a 0 width, it will always draw one pixel wide, regardless of the scaling. It just says "Scale as if this was the center". It is easier to see in Rotate Transform which uses a similar concept.
If you set up the same canvas with a RotateTransform, with the Center set to 0, 0the whole canvas rotates around that point.

If you set it to 50, 50the canvas rotates around the upper left corner of the rectangle, etc. This doesn't move the rectangle to the center of the canvas either, it is just the point to apply the transformation "from".
So in scale transform, if my center is 0, 0then all the scaling happens to the bottom and right. Put it at 50, 50 and it becomes a little bigger at the top and left, but the majority is still at the bottom and right. Put it atand all directions expand equally.

Update I'm not sure about the reflected implementation, but here is another way to think about it. ScaleTransform is designed to simply scale a control. Scaling should not involve moving child elements relative to each other that would be translationthis motion would be necessary to get the behavior you describe. The "center" variables are just the center of the transformation, they do not affect the position of an element relative to the parent especially in a canvas, where these values are hard-coded.
Also, all the transforms are "render" transforms, which means it just affects the display, the underlying control remains the same. No scaling you could ever do should make an object that is in the upper left corner of a parent object suddenly appear in the center. Update 2 I believe I see what that final check is doing:
