What is ImageData?
Similarly, it is asked, which method returns an object that contains image data of a specific ImageData object?
The ImageData data property is used to return an object that contains image data of the specified ImageData object.
Likewise, how do I find the URL of a canvas image? To get the image data URL of the canvas, we can use the toDataURL() method of the canvas object which converts the canvas drawing into a 64 bit encoded PNG URL. If you'd like for the image data URL to be in the jpeg format, you can pass image/jpeg as the first argument in the toDataURL() method.
Keeping this in consideration, how do I get data from canvas?
To get the image data for each pixel of a rectangular area on the canvas, we can get the image data object with the getImageData() method of the canvas context and then access the pixel data from the data property. Each pixel in the image data contains four components, a red, green, blue, and alpha component.
How do I find the pixel data of an image?
The procedure for extraction is :
- import the Image module of PIL into the shell: >>>from PIL import Image.
- create an image object and open the image for reading mode: >>>im = Image.open('myfile.png', ' r')
- we use a function of Image module called getdata() to extract the pixel values.
