Transform.scale and canvas.scale not Scaling at the Same Rate

Asked 2022-Apr-17 at 20:54

I have a Flutter app where I'm rendering a CustomPainter and a Widget in a Stack. When I pass the scale and translate amount into canvas.scale() and canvas.translate, then pass the scale into the Transform.scale and Transform.translate - the two items scale offset's scale differently. View at the bottom of this post to see what this looks like.

Here is the code that has the Stack widget:

Clip objects drawn outside of canvas

Asked 2021-Dec-07 at 09:25

How can I clip objects drawn outside a canvas? In the following, the black square represents the boundary of the canvas. I do not want the left half the circle to be drawn because it is outside the canvas:

This is simple example, but I am drawing PNGs and SVGs inside a canvas with various transformations applied to them, and I need a solution that would clip the portion drawn outside the canvas.

Here is the code for the above:

To prevent a widget to draw beyond its layout size, use ClipRect to clip it. For rounded rect shape use ClipRRect and ClipPath for custom shape.

QUESTION

Neural Network is not predicting the correct digit

Asked 2021-Jun-30 at 13:30

I am new to ML and for my project, I am trying to make a digit classifier using neural networks. I have made a GUI where you can draw the digit and it will pass the NumPy Array to the neural network. I have trained my neural network with mnist digit data set with a model accuracy of 97.70% yet it cannot predict the digits entered.

You apparently use if __name__ =='__main__': in two files, and you train the network only when you call the network's file, while when you launch your GUI application your network is created untrained there self.object = mltest(). Unless you call self.object.train(), it'll probably remain untrained and thus incapable of good predictions

QUESTION

Why do I get an error when calling my method?

Asked 2020-Dec-02 at 21:15

I have created a paint UI and I want to change the size of the brush using a QSlider.

I want to call a method when the user changes the value of the slider

...

ANSWER

Answered 2020-Dec-02 at 21:15

There are two very important problems:

while your changeBrushSize function has two (positional) arguments, the first (self) is always referred to the instance, so you should not normally provide it: when an instance method is called, the self is always implied, so the call should be self.changeBrushSize(5), since only the second size argument will be used; the last error you got is because you tried to provide more arguments, and there's no use to that;
connect() takes a callable as argument, while you are actually executing the function (which probably returns None), and even if you removed that self as explained above, the program will crash anyway because what the function returns is not a callable;

If you want to update the self.brushSize value when the slider changes, do the following:

QUESTION

Rotate painted text about its center

Asked 2020-Nov-10 at 16:18

I'm trying to rotate text painted on a Canvas about it's center. Instead, in the below code, the text rotates about the top left corner of the text when I press the floating button.

Pressing the button increments the angle, which is passed to CanvasPainter to draw the text.

The rectangle's top left corner should be initially positioned at offset.

draw on the lower part of the window PyQt5

Asked 2020-Sep-23 at 19:20

I am trying to make a program the paints on the half button of the screen only, but as you can see the painting is shifted towards the bottom, if I draw in the upper part, the paint happens in the lower part. What I want is to draw directly in the bottom part.

here is my code:

ANSWER

Answered 2020-Sep-23 at 19:20

Do not complicate the task dividing the painting area within the widget, a simpler solution is to create a widget where the painting is done completely and then place it at the bottom of the main window.
