CmykColorHelper Class

Summary: Helper methods to work with CMYK color presented as a signed 32-bit integer value.
Provides the similar API as the CmykColor struct.
It’s more lightweight because CMYK color is presented just as Int32 rather than structure with internal fields.
Please prefer to use static methods of this class when possible instead of the deprecated
CmykColor struct.

Examples

The following example fills the central area of a raster image with black pixels using the aspose.imaging.RasterImage.save_cmyk_32_pixels method.

from aspose.pycore import as_of
from aspose.imaging import Image, RasterImage, Rectangle, Color, CmykColorHelper
from os.path import join as join_path

directory = r"c:\temp"

with Image.load(join_path(directory, "sample.png")) as image:
	rasterImage = as_of(image, RasterImage)
	# Get an integer representation of black in the CMYK color space.
	blackCmyk = CmykColorHelper.to_cmyk(Color.black)
	# The black square.
	pixel_count = (rasterImage.width // 2) * (rasterImage.height // 2)
	pixels = [blackCmyk] * pixel_count
	# Draw the black square at the center of the image.
	area = Rectangle(rasterImage.width // 4, rasterImage.height // 4, rasterImage.width // 2, rasterImage.height // 2)
	rasterImage.save_cmyk_32_pixels(area, pixels)

	rasterImage.save(join_path(directory, "sample.SaveCmyk32Pixels.png"))

The following example shows how to convert RGB colors to their CMYK counterparts without applying ICC profiles.

from aspose.imaging import Color, CmykColorHelper

rgbColors = [Color.red, Color.green, Color.blue]

print("Convert RGB to CMYK without using ICC profiles.")
for rgbColor in rgbColors:
	cmyk = CmykColorHelper.to_cmyk(rgbColor)
	c = CmykColorHelper.get_c(cmyk)
	m = CmykColorHelper.get_m(cmyk)
	y = CmykColorHelper.get_y(cmyk)
	k = CmykColorHelper.get_k(cmyk)
	print(f"RGB({rgbColor.r},{rgbColor.g},{rgbColor.b})\t\t=> CMYK({c},{m},{y},{k})")

# The output looks like this:
# Convert RGB to CMYK without using ICC profiles.
# RGB(255,0,0)		=> CMYK(0,255,255,0)
# RGB(0,128,0)		=> CMYK(255,0,255,127)
# RGB(0,0,255)		=> CMYK(255,255,0,0)
