![]() For instance, tint (255, 128) will make an image 50 transparent (assuming the default alpha range of 0-255, which can be changed with colorMode () ). I display the image at the position of the mouseīlend(img, 0, 0, img.width, img.height, mouseX, mouseY, img.width, img. To apply transparency to an image without affecting its color, use white as the tint color and specify an alpha value. The result will look something like this: The Round Cutout Mask Feel free to use this mask: right-click and save-as Essentially a transparent rectangle with a fuzzy black (non-transparent) dot in the middle. Then you will know youve tried everything in addition to Windows Update. You can also try older drivers in Device Manager > Display device > Driver tab > Update Driver > Browse > Let Me Pick. Make sure to enable transparency with your PNG. For Display issues one fix that is working is to Roll back or Uninstall the Driver on the Display Device > Driver tab, restart PC to reinstall driver. meaning that the white background for instance is not shown. The easiest way to do that is to use File Export Export As. here i blend() the eye image so that only the darkest colors come through Image Module Pillow (PIL Fork) 4.2.1 documentation This article describes the following contents with sample code. here I display the original image of the eye in the corner of the window The image processing library Pillow (PIL) of Python provides Image.crop() for cutting out a partial area of an image. If you pass a image with transparency, then the alpha channel is used as mask. It indicates a mask that will be used to paste the image. You can use this module to create new images, annotate or retouch existing images, and to generate graphics on the fly for web use. Your code is pretty much working for me if I just change one thing: Save the image in the PNG format instead of JPEG. Second are coordinates, and the secret sauce is the third parameter. The ImageDraw module provide simple 2D graphics for Image objects. here set all pixels in the PImage "bg" to be color(200) Given that I keep coming back to this issue whenever I want to draw a transparent rectangle with PIL, I decided to give an update. This is basically the effect that I am looking for, (but in the following code I use a jpg and play around with the blend() method: PImage bg The background of the website is white, so 'right click' the Output and 'open image in new tab' and youll see that it is transparent :) import cv2 import numpy as np read the image imagebgr cv2.imread imagebgr. ![]() This is actually the only image I found with an alpha channel. Basically this is what I have been doing:Īs I grabbed more and more “png images” from the web I noticed that you can look up whether they have an alfa channel or not, in the file info. ![]()
