To make a rectangle transparent in Photopea, you adjust the Opacity setting of the layer that the rectangle is on. Transparency in Photopea is controlled at the layer level.
Adjusting Layer Opacity for Transparency
Whether your rectangle is on a Shape Layer, a Pixel Layer, or even within a Layer Group, its transparency is determined by its layer's Opacity.
Here's how to make a layer transparent:
- Select the Layer: In the Layers panel (usually on the right side of the Photopea interface), click on the layer containing your rectangle. Ensure the correct layer is highlighted.
- Locate the Opacity Slider: At the top of the Layers panel, you will find a setting labeled "Opacity" with a percentage value (defaulting to 100%).
- Reduce the Opacity: Click on the percentage value or the small arrow next to it to reveal a slider. Drag the slider to the left to decrease the opacity. A lower percentage means higher transparency. For example, setting Opacity to 50% will make the layer semi-transparent.
- Confirm the Change: As you move the slider, you will see the transparency of the rectangle update instantly on the canvas. Release the slider when you reach the desired level of transparency.
Understanding Layer Types
The method above applies regardless of how the rectangle was created:
- Shape Layer: Created using the Rectangle Tool (U). These are vector shapes.
- Pixel Layer: Drawn or painted onto a standard pixel layer.
- Smart Object: If the rectangle is part of a Smart Object, you might need to edit the Smart Object's contents or adjust the Smart Object layer's opacity.
Other Layer Operations in Photopea
Photopea provides numerous options for managing layers, which are fundamental to image editing. According to one reference discussing layer operations, you can interact with layers by selecting them and using menus like 'Layer'. For instance, after selecting a layer (like one labeled "layer one"), you can go to the Layer menu and choose New Fill Layer to add a new layer filled with a solid color, gradient, or pattern. While creating a new fill layer is different from adjusting transparency, this demonstrates how the Layer menu is used for various modifications and additions related to layers in Photopea.
By adjusting the Opacity of the layer containing your rectangle, you can easily control its transparency, allowing content beneath it to show through.
