Python OpenCV | cv2.putText() method (original) (raw)
Last Updated : 09 Aug, 2024
**OpenCV-Python
is a library of Python bindings designed to solve computer vision problems.
cv2.putText()
method is used to draw a text string on any image.
**Syntax: cv2.putText(image, text, org, font, fontScale, color[, thickness[, lineType[, bottomLeftOrigin]]]) **Parameters:image: It is the image on which text is to be drawn. **text: Text string to be drawn. **org: It is the coordinates of the bottom-left corner of the text string in the image. The coordinates are represented as tuples of two values i.e. (**X coordinate value, **Y coordinate value). **font: It denotes the font type. Some of font types are **FONT_HERSHEY_SIMPLEX, FONT_HERSHEY_PLAIN, , etc. **fontScale: Font scale factor that is multiplied by the font-specific base size. **color: It is the color of text string to be drawn. For **BGR, we pass a tuple. eg: (255, 0, 0) for blue color. **thickness: It is the thickness of the line in **px. **lineType: This is an optional parameter.It gives the type of the line to be used. **bottomLeftOrigin: This is an optional parameter. When it is true, the image data origin is at the bottom-left corner. Otherwise, it is at the top-left corner. **Return Value: It returns an image.
**Image used for all the below examples:
**Example #1:
Python3 1== `
Python program to explain cv2.putText() method
importing cv2
import cv2
path
path = r'C:\Users\Rajnish\Desktop\geeksforgeeks\geeks.png'
Reading an image in default mode
image = cv2.imread(path)
Window name in which image is displayed
window_name = 'Image'
font
font = cv2.FONT_HERSHEY_SIMPLEX
org
org = (50, 50)
fontScale
fontScale = 1
Blue color in BGR
color = (255, 0, 0)
Line thickness of 2 px
thickness = 2
Using cv2.putText() method
image = cv2.putText(image, 'OpenCV', org, font, fontScale, color, thickness, cv2.LINE_AA)
Displaying the image
cv2.imshow(window_name, image)
`
**Example #2:
Python3 1== `
Python program to explain cv2.putText() method
importing cv2
import cv2
path
path = r'C:\Users\Rajnish\Desktop\geeksforgeeks\geeks.png'
Reading an image in default mode
image = cv2.imread(path)
Window name in which image is displayed
window_name = 'Image'
text
text = 'GeeksforGeeks'
font
font = cv2.FONT_HERSHEY_SIMPLEX
org
org = (00, 185)
fontScale
fontScale = 1
Red color in BGR
color = (0, 0, 255)
Line thickness of 2 px
thickness = 2
Using cv2.putText() method
image = cv2.putText(image, text, org, font, fontScale, color, thickness, cv2.LINE_AA, False)
Using cv2.putText() method
image = cv2.putText(image, text, org, font, fontScale, color, thickness, cv2.LINE_AA, True)
Displaying the image
cv2.imshow(window_name, image)
`
**Output:
