Circular ColorPicker for PyQt Python.
This is a new design PyQt ColorPicker for python.
The color circle is actually an image and the hue values are generated from finding the tangent of the distance of the mouse coordinates + center coordinates only within the colorpickerWheel class.
Make sure that all the files are in the same directory with the executable/script or change the "working_directory" variable.
Call the ColorPicker class like this (change the variables)
Colorpicker = ColorPicker(width=250, startupcolor=[0, 255, 255]) # HSV (0-360, 0-255, 0-255)
The colorcycle calls the function "onCurrentColorChanged" in "ColorPicker" class when the color changes. There it returns 3 arrays
hsv_color_array = color[0] # (H(0-255), S(0-255), V(0-255))
hsv_color_array_base_360 = color[2] # (H(0-360), S(0-100), V(0-100))
rgb_color_array = color[1] # (R(0-255), G(0-255), B(0-255))
If you need to use HSV with other values like (H(0-1), S(0-1), V(0-1)) use a conversion like
hsv_color_array_base_1 = [hsv_color_array[0]/255, hsv_color_array[1]/255, hsv_color_array[2]/255]
If you change the width the mouseDot might seem a bit off, this can be fixed on the colorpickerWheel class initiation
Values that can be changed:
self.sliders = colorpicker_sliders(slidersWidgetWidth=self.width, spaceBetweenColorpickerAndSliders=0,
spaceBetweenSliders=0)
####
#"colorpicker_sliders" class must be initiated before "colorpickerWheel" class because it is passed to "colorpickerWheel"
####
self.colorpickerWidget = colorpickerWheel(colorpickerSize=self.width, startupcolor=self.startup_color,
mouseDot_size=30, mouseDotDistance_changer=2,
centralColorWidget_size=55, centralColorWidget_radius=20,
centerColorWidget_isCircle=True, sliders=self.sliders)
colorpickerSize=self.width by default is inherited when you initialize the ColorPicker class
startupcolor=self.startup_color by default is inherited when you initialize the ColorPicker class
mouseDot_size=30 changes the size of the mouse circle that moves around the circle
mouseDotDistance_changer=2 changes the distance of mouseFot from the center
centralColorWidget_size=55 changes the size of the color widget inside the circle
centralColorWidget_radius=20 changes the border-radius of the color widget inside the circle
centerColorWidget_isCircle=True if True sets the central color widget as a circle and ignores the value of centralColorWidget_radius
change_alpha_channel=True if True changes the central color widget alpha channel (opacity) based on the value of brightness slider
sliders=self.sliders is default, do not remove unless you remove all functoions associated with sliders
You can get the updated values outside the class like this
print(ColorPicker.hsv_color_array)
Notice - If you use this as a widget set oboject names for QPushButtons and QSliders of parent because it affects the child widget.
