The gradient is defined by two points: (from_x, from_y) and (to_x, to_y), along which the specified colors are interpolated. Optionally, you can set a background color, extend the gradient beyond its start or end, and specify custom color stop positions via `bounds`. Args: fpdf (FPDF): The FPDF instance used for PDF generation. from_x (int or float): The x-coordinate of the starting point of the gradient, in user space units. from_y (int or float): The y-coordinate of the starting point of the gradient, in user space units. to_x (int or float): The x-coordinate of the ending point of the gradient, in user space units. to_y (int or float): The y-coordinate of the ending point of the gradient, in user space units. colors (List[str or Tuple[int, int, int]]): A list of colors along which the gradient will be interpolated. Colors may be given as hex strings (e.g., "#FF0000") or (R, G, B) tuples. background (str or Tuple[int, int, int], optional): A background color to use if the gradient does not fully cover the region it is applied to. Defaults to None (no background). extend_before (bool, optional): Whether to extend the first color beyond the starting point (from_x, from_y). Defaults to False. extend_after (bool, optional): Whether to extend the last color beyond the ending point (to_x, to_y). Defaults to False. bounds (List[float], optional): An optional list of floats in the range (0, 1) that represent gradient stops for color transitions. The number of bounds should be two less than the number of colors (for multi-color gradients). Defaults to None, which evenly distributes color stops. r<rNrrhkrkrh)rrrrrrrJrirmrnr\rkr@r s r!rLinearGradient.__init__sb\ ]&Q&&6/4$?4:;Fq&&1*S)*F; [TU]XXU 5 UURU- UUURU- U/n U Vs/sHoRU-SPM snUlSUlgs snf)a A shading pattern that creates a radial (or circular/elliptical) gradient in a PDF. The gradient is defined by two circles (start and end). Colors are blended from the start circle to the end circle, forming a radial gradient. You can optionally set a background color, extend the gradient beyond its circles, and provide custom color stop positions via `bounds`. Args: fpdf (FPDF): The FPDF instance used for PDF generation. start_circle_x (int or float): The x-coordinate of the inner circle's center, in user space units. start_circle_y (int or float): The y-coordinate of the inner circle's center, in user space units. start_circle_radius (int or float): The radius of the inner circle, in user space units. end_circle_x (int or float): The x-coordinate of the outer circle's center, in user space units. end_circle_y (int or float): The y-coordinate of the outer circle's center, in user space units. end_circle_radius (int or float): The radius of the outer circle, in user space units. colors (List[str or Tuple[int, int, int]]): A list of colors along which the gradient will be interpolated. Colors may be given as hex strings (e.g., "#FF0000") or (R, G, B) tuples. background (str or Tuple[int, int, int], optional): A background color to display if the gradient does not fully cover the region it's applied to. Defaults to None (no background). extend_before (bool, optional): Whether to extend the gradient beyond the start circle. Defaults to False. extend_after (bool, optional): Whether to extend the gradient beyond the end circle. Defaults to False. bounds (List[float], optional): An optional list of floats in the range (0, 1) that represent gradient stops for color transitions. The number of bounds should be one less than the number of colors (for multi-color gradients).
