What are the uses of layers in ps?
1. Layers can accurately position elements on the page
2. Layers can add text, pictures, tables, plug-ins, and layers can also be nested inside. .
3. Layers can make the drawn works highly modifiable.
In layman's terms, layers are like films containing elements such as text or graphics. They are stacked one by one in order to form the final effect of the page.
For example, if you paint on sheets of transparent cellophane, you can see the content on the paper below through the cellophane above, but no matter how you paint on the upper layer, it will not affect the bottom. of cellophane, the upper layer will obscure the image below. Finally, the cellophane is superimposed, and the final composite effect can be changed by moving the relative positions of each layer of cellophane or adding more cellophane.
Basic layer operations:
Rasterized layer
Generally created layers such as text layers, shape layers, vector masks and fill layers cannot be processed using painting tools or filters on their layers. If you want to continue working on these layers, you will use rasterization layers, which convert the contents of these layers into flat raster images.
Let’s see through an example whether it is necessary to select “Delete Grid Layer” when performing some effect processing. First use the graphics tool to draw a graphic on the layer (the graphic is in path state at this time), and then add an effect to the graphic under the "Filter" menu.
One way to delete a layer is to select the layer, right-click the mouse and select the "Delete Layer" option, or select the "Delete" option in the "Layer" menu. options.
Merge layers
During design, many graphics are distributed on multiple layers, and these determined graphics will not be modified, just They can be merged together for easier image management. In the merged layer, any overlapping transparent areas will remain transparent.
If you want to merge all the layers together, you can choose options such as "Merge Visible Layers" and "Flat Layers" in the menu. If you choose to merge several of the layers, according to the content on the layer Some of them need to be deleted before they can be merged.
After gridding, the "Merge Down" option appears in the menu. The layers to be merged are gathered together, and several layers among all the layers can be merged.
Layer style
Layer style is a very practical function of Photoshop 5, which can simplify many operations. You can use it to quickly generate shadow, relief, glow and other effects. But they are all for a single layer.
