Hello, I would like to know how to know how to create a box shape in photoshop that has only some of it's corners rounded like so: http://studios29.com/sample.jpg
I know I can create a box shape with all 4 rounded corners with the 'rounded rectangle tool', but im not sure how to use it to do what i want.
You could do it a couple ways, create the rounded box, then raster the layer and delete part of it that you don't want rounded. Or you could use a mask on the vector layer.
You can create the box, fill it and then cut off the bottom half or you can just edit the box path, deleting a few of the extra paths, then straightening out the lines.
If you need more detailed steps, just say so and I'll go through it step by step.
You could use the Rounded rectangle shape setting the radius to the required setting (looking at the screenshot I'd say 4-6) and then use the Subtract from shape layer and then select the Retangle Tool and subtract the bottom third of your original shape.
it depends on what kind of functionality you're after.
if you're working with a rounded corner box and you need a coloured bar across the top, you're better off leaving the rounded box alone, then creating the bar on a second layer and creating a clipping mask (ctrl+alt+g pc, cmd+op.+g mac).
if there's no bounding box, IE a standalone title bar, you're better of just deleting the bottom most points, then resetting the bezier arms.
