What Does Rasterize Mean in Photoshop?
Whether you’re working with text, shapes, or smart objects, you may discover the necessity to “rasterize” the layer. Perhaps you wish to edit the layer, change the color, or erase parts of the image, but it’s difficult to do so without rasterization.
Rasterizing a layer means you’re converting a vector layer to pixels. This changes how your layer is displayed and the editing capabilities you have. When a vector becomes rasterized, you’ll see the pixels along the perimeters rather than a clean line. However, you gain the flexibility to directly edit the layer.
To better understand the meaning behind rasterizing in Photoshop, let’s bear the needs of this feature.
What is the aim of Rasterizing a Layer?
Rasterizing a layer will convert any type of vector layer into pixels. As a vector layer, the image is formed of geometric formulas to make the contents of your image. This is perfect for graphics that require clean edges or scaling up significantly.
The problem with vectors is that they are not compatible with pixel effects like brush adjustments or the eraser tool. This means in some instances, you won’t be able to apply the effects you want to a vector layer because it can’t be mixed with a pixel layer.
That’s where rasterizing comes into play. By rasterizing the layer, you can convert the vector from a geometric formula and turn it into pixels. That way, you can apply pixel-type effects onto your layer with no issues.
When should you Rasterize a Layer in Photoshop?
With that said, rasterizing a layer isn’t an excellent way of editing non-destructively. Since it’s a permanent change, it’s not necessarily a good idea. After all, what if you change your mind and want to go back to your original vector? After rasterizing a layer, this won’t be possible. Whenever you can, it’s more advantageous to duplicate and rasterize your vector layers so you always have a backup.
For example, if you wanted to edit a shape layer directly, you could duplicate the layer and rasterize the duplicate. That way, you have the option to change your mind later or start over if you make the wrong adjustment.
