💡 Tips and Tricks

Text Readability

When overlaying text on complex backgrounds, consider using semi-transparent backgrounds for the text to enhance readability. Adjust the text color to contrast with the image for better visibility.

Test with Various Inputs

Use different success and failure texts along with sample images to ensure proper positioning and font scaling for various scenarios.

🛠️ Troubleshooting

Text Overlapping with Image Edges

If the text is cut off or not fully visible, try adjusting the Horizontal Position and Vertical Position sliders to move the text further from the edges of the image.

Ensure Condition Input Works

If the text does not change based on the condition, ensure the Condition input is being updated correctly and is linked to a valid boolean source.
