Scale Bar Python Script - Zen Lite 3.7

[Marcos Paulo Pereira Dias]

Scale Bar via Python Script

Hello!

At my workplace, we use a script to process images of petrographic samples. The script used to work perfectly fine, but after updating from ZEN version 3.7, the script stopped working. It successfully inserts the scale bar in the correct position on the image, but when the .JPG file is generated, the scale bar is placed in the default position (bottom right corner), and we need it to be in the top left corner. Please help us!

This is code:

To create a scale bar using Python and Zen Lite 3.7 software, you would typically need to access the Zen Lite software's API (Application Programming Interface) or SDK (Software Development Kit). Unfortunately, as an AI text-based model, I don't have access to the specific functions and capabilities of the Zen Lite software. If anyone want to know about Garage door spring repair shortpump

Replace the following lines in your code:

Code: Select all

xbarpos=xsize/10
ybarpos=ysize/10

With:

Code: Select all

xbarpos = xsize / 20  # Adjust as needed
ybarpos = ysize / 20  # Adjust as needed

These adjustments will position the scale bar closer to the top left corner. You may need to fine-tune the xbarpos and ybarpos values based on your specific requirements.
