What does that box in the bottom right corner of PS mean

It is the identification of smart objects, such a layer, the function is limited, if you want to do it, you need to right-click the mouse, select "rasterize layer" and then release the limit.

You can take advantage of Smart Objects to do the following:

Performs a non-destructive transformation. Layers can be scaled, rotated, skewed, distorted, perspective-transformed, or deformed without losing the original image data or losing quality because the transformation does not affect the original data.

Work with vector data, such as those in Illustrator, which would be rasterized in Photoshop without the use of Smart Objects.

Apply filters non-destructively. Filters that can be applied to Smart Objects at any time.

A Smart Object and automatically updates all of its linked instances.

Applies a layer mask that is linked or unlinked to a Smart Object layer.

You can't perform operations (such as painting, dodging, burning, or closing) directly on a Smart Object layer that alter the pixel data unless you first convert the layer to a regular layer (which will be rasterized). To perform an operation that alters the pixel data, you can clone the contents of a Smart Object, clone a new layer on top of the Smart Object layer, make a copy of the Smart Object, or create a new layer.

Indicates that this layer is vector.

A thumbnail of a layer with a shape, which means that this layer can be enlarged wirelessly without distortion inside the PS.

This small box is the identification of the smart object, such a layer, the function is limited, if you want to do it, you need to right-click the mouse, select "rasterize layer" and then release the limit. I hope it can help you

Hello, it's the shape layer, use the Pen tool, or the Rounded Rectangle below and other tools. Choose a shape and you can draw it.

Press Ctrl+Enter to convert the shape route into a curved selection... ps: Shape layer, will be kept. It's just that there's one more curve coming out).

Just a thumbnail of a layer.

This is a vector layer on the Photoshop Layers panel that appends the Stroke effect directly, and this icon indicates that it is in the "Shape" or "Work Path" state. See Figure 1

On the other hand, let's say you want to change the selection into a path, and after making the selection, open the [Paths] panel, and below it, you will see the options for this icon. See Figure 2 (at "Generate Work Path from Selection").

Vector tools in Photoshop include: Rectangle Tool, Rounded Rectangle Tool, Ellipse Tool, Polygon Tool, 、......Text tool, pen tool.

This means that you are using the Rectangle tool, and if you are using the Marquee tool to repopulate, you will not have this icon.

1. The software used in the demonstration is the image processing software Photoshop, and the version used is Photoshop CS6.

2. Open the PS image processing software and create a new **, you can see that there are many small gray and white squares on the newly created ** at this time, this is because we selected the background color as transparent when creating a new layer.

3. At this time, we create a new one, and set the background content to white or background color, click to confirm the new layer and close the new window.

4. You can see that the new layer we created at this time does not have a small gray and white square, but a white background.

Selection: Also called selection range, it is the range that PS does to the image, and anything outside the selection is invalid. When no selection area is established on the image, it is equivalent to a full selection.

The thin black and white line is the boundary of the selection area, and the manipulation of the image is only valid for the selection area.

Feather: Softens the edges of the selection to create a transition to the image's boundaries in the selection. The range is 0 250, and when the effective pixels in the selected area are less than 50%, the boundary line of the selection is no longer displayed on the image.

The effect of filling selections with different feather values.

Anti-aliasing: As the image is being processed, PS auto-complements the pixels at its edges, making the transitions between adjacent pixel points on its edges softer. In PS, it is mainly aimed at creating a selection area.

For the effect of anti-aliasing and selection fill with preserved aliasing, the view has been zoomed in for ease of viewing.

Tolerance: The range of colors between pixels on the image, the larger the tolerance, the greater the range that is the same as the selected pixel point, with a value of 0-255.

The image above is the result of using the Magic Wand Selection tool to make discontinuous selections on the image at different tolerance values.

Blending mode: The method of applying one color to another color according to specific mixing rules to obtain the resulting color is called color mixing, and this specification is called blending mode, also known as color mixing mode. There are 6 groups of 22 blending modes in PS.

This is the navigator, which adjusts the position and size of the window. The way to close it is: Window - uncheck the navigator.

This is the navigator panel, you can hide or shrink the navigator panel.

Hold down Alt and it will appear.

Normally, if I adjust the hue on the layer, I will press it, and then I will only target the layer below.

This is CC and CC2014 The new version of the vector layer is not blurred when zooming in or out, and the function is more powerful than the previous version, and the vector layer can be merged with each other, and it will not become a normal layer.

Shortcut keys you and p can create this kind of layer, remember to select "shape" in the upper left corner, if you choose "path" is the same as usual, just draw the path, do not generate layers "pixels" is directly drawn on the ordinary layer, not very useful.

This is the shape of the path, and this is a vector shape that can be drawn with this icon.
