Cartography/imaging: understanding projection between heterogeneous 2D coordinate systems
Assumptions; the question is very agnostic to any languages or tooling, although I am approaching with
CSharp and SkiaSharp specifically, but is neither here nor there concerning the core question. Which is: projecting between a world coordinate system and canvas resolution coordinates.
The world coordinate system is very large, 1.5M whole numbers, represented as decimal for centimeters and fractional cm precision; neither here nor there except to understand the A coordinate system. The B coordinate space of course is the target bitmap, in whatever resolution, may be 8K, 16K even 32K, bandwidth and memory permitting, square.
Thus far the naive attempt is to apply a simple world per bitmap ratio, or pixels per world, depending upon the point or rectangle bounds conversion. But there is always an error. Example image: the circle and points are accurate relative to themselves; but are inaccurate to the target bitmap in question, the scaling being something like 183 units per px error involved applying any ratios to the source coordinates. This error can vary depending on the source bitmap resolution, of course. So the algorithm should be robust keeping that in mind....
✅ Visio for C# class program
HI. Does someone know how in microsoft Visio can make the "Applies to ->" and the arrow?
✅ Making a chess program. Why is this happening?
I don't understand this error and nothing online makes sense to me, so can I get a firsthand explanation of what I've done wrong? Or probably done wrong?
Using code to reference code
So I have a collider, and I have code elsewhere that tells my UI counter to go up. That code lives in LogicScript and it's called addScore. I'm trying my best to reference it within my collider's script using the tag "Logic", but there's definitely something wrong with that big logic = line as well as the logic.addscore line. Does anyone have any advice? :')
Priority queue, queue empty error.
Hi, I am getting an error when trying to use the peek method that says that the queue is empty. However just before this I use the enqueue method to put something into it. Why is this error occurring?
