In IBIS Paint (or IBIS Paint X), cutting out a person or object can be done using a combination of selection tools and layer techniques. Here are some tips for cutting out an object in IBIS Paint:

1. Use the Selection Tools:

Lasso Tool: This tool allows you to manually trace around the object. You can adjust the width of the trace, making it easier to follow complex edges. Once the object is fully traced, you can turn it into a selection.
Magic Wand Tool: This tool works well when the object has a solid color or clear boundaries. It will automatically select areas with similar colors, but you may need to adjust the tolerance for more precise selection.
Polygonal Lasso Tool: Similar to the Lasso Tool but uses straight lines, great for objects with sharp edges.

2. Adjust the Selection Area:
After using the selection tool, you can refine the selection using the "Adjust Selection" option. This allows you to fine-tune the edges to get a more precise cutout.

3. Feather the Selection:In IBIS Paint, you can feather the edges of your selection to smooth the transition between the object and the background. This is useful if the object has soft edges like hair or fur. To do this, go to the "Selection" menu, choose "Feather", and adjust the softness of the selection's edges.

4. Layer Masks (Non-Destructive Editing):
IBIS Paint doesn't have full support for layer masks like Photoshop, but you can use the "Invert Selection" feature and delete the unwanted background. Keep a duplicate layer for backup just in case.You can also use the "Cut" and "Paste" functions to move the object to a new layer.

5. Use the Brush Tool to Refine Edges:
After cutting out the object, there might be some rough edges. Use the Brush Tool with a soft, low-opacity brush to clean up and blend the cutout into the new background.You can also use the Eraser Tool to carefully erase any unwanted parts around the edges.

6. Zoom In for Detail Work:
Use the zoom feature to get a closer look at your selection, especially when working on small, intricate details like hair or objects with small borders.

7. Add a New Background:
Once you've successfully cut out your object, you can paste it onto a new background. To make it blend seamlessly, adjust the Brightness/Contrast of the new background or use a feathered edge to soften the transition.

8. Use Layers for Flexibility:
Work with multiple layers to keep the cutout object and the background separate. This way, you can adjust the object's position, resize it, or tweak the edges without affecting the original image.
