Windows Still Image Architecture basic Python image acquisition
To acquire images from a Still Image (STI) device using Windows Still Image (WIA) architecture in Python, you can use the pywia
library. This library provides a simple interface to interact with WIA devices and capture images.
Here's how you can use pywia
to acquire images from a WIA device:
Install pywia:
You can install thepywia
library usingpip
:bashpip install pywia
Capture Images:
Use the following Python script to acquire images from a WIA device:pythonimport pywia
def acquire_images():
# Create a WIA object
wia = pywia.Wia()
# Select a WIA device (STI device)
device = wia.select_device()
if device is None:
print("No WIA device selected.")
return
print(f"Selected device: {device.name}")
# Set the properties for the image acquisition
properties = {
'6146': 1, # WIA_IPA_DATATYPE: 1 (Color)
'6147': 300, # WIA_IPA_XRES: 300 DPI (horizontal resolution)
'6148': 300, # WIA_IPA_YRES: 300 DPI (vertical resolution)
}
# Acquire the image from the device
image = device.acquire_image(properties)
# Save the acquired image
if image:
image.save("captured_image.jpg")
print("Image acquired and saved successfully.")
if __name__ == "__main__":
acquire_images()
This script uses the
pywia
library to select a WIA device, set the properties for image acquisition (e.g., color, resolution), and then capture an image from the device. The acquired image is saved as "captured_image.jpg" in the current working directory.Note: The properties used in the example are for illustration purposes. You can adjust them based on your specific requirements and the capabilities of the WIA device you are using.
Please make sure you have a compatible WIA device connected to your Windows machine before running the script. Additionally, the pywia
library may not support all types of WIA devices, so ensure that your specific device is supported. Refer to the documentation of the pywia
library for more details and additional functionalities.
