I am using the python imaging library I think I have the following parts correct: image = Image.open("cover.jpg") image = image.resize((150,150),Image.ANTIALIAS) png = image.tostring("PNG") I am taking the image data from the file, resizing the image, and then using the PNG coder to force it into a PNG format image and converting it to a string.
Read image arrays from image files¶ In order to create a numerical array to be passed to px.imshow, you can use a third-party library like PIL, scikit-image or opencv. We show below how to open an image from a file with skimage.io.imread, and alternatively how to load a demo image from skimage.data.
To convert RGB to HSV, input your RGB color codes to RGB area, for example, rgb(40, 110, 255) To convert HSL to RGB, input your HSL color codes to RGB area, for example, hsl(220, 100%, 58%) To convert HEX to HSV, input your HEX color codes to HEX area, for example, #286eff; Our color code converter will show results interactively
