What does rasterizing a layer mean?

Rasterization is to convert vector images into bitmaps.The vector image processing method is different from the bitmap processing method. In order to use the bitmap processing method, it must be rasterized.

For example, the text layer is a vector layer. Before rasterization, you can adjust the character size and font, but you cannot fill it with gradients, and you cannot use filters such as Gaussian blur and distortion. After rasterization, you can use filters and fill, but you can no longer change the font size.

To perform filters, shapes (such as segmentation), brush drawing, etc., the layer content must be in bitmap form, if it is text, or a shape drawing with a path (mask vector drawing), vector pattern , all are vector images and cannot be directly processed above, so these vector elements must be converted into bitmap form. Commonly known as rasterization.
