My history pen doesn t work, and the prompt is that there is no history status and is designated as

This error message may be caused by a problem with some settings or components of your drawing application. Here are some possible solutions:

1.Make sure that you have set up the source of your history pen correctly. In most drawing applications, you need to select a specific layer or history state as the source before you can use the history pen.

Please check your settings to make sure you have selected the correct source.

2.If you're sure the settings are correct, but you still can't use the history pen, try restarting your drawing app. Sometimes, the app may malfunction or error, and a reboot can fix many of the issues.

3.If restarting the app doesn't fix the problem, try updating your drawing app, or uninstall and reinstall the app. This can resolve certain application-related conflicts or issues.

If the content of the history brush source is inconsistent with your current canvas content, such as file size, color mode, etc., you will not be able to perform the history brush operation, but if the source you selected is the same as the current canvas content in terms of size, color mode, and current layer, you can use the history brush.

The function of the history brush is just to restore the place where the brush has been painted to the history node of the current setting, and the default is restored to the state when it was opened, if you just open a file, it will definitely have no effect with history.

Use the History Art Brush tool:

1.In the History palette, click the left column of the status or snapshot to use it as the source for the History Art Brush tool. A brush icon appears next to the source history status.

2.Select the History Art Brush tool .

In the options bar, do the following:

3.Choose a brush and set brush options. (See Use brushes.) Specifies the blending mode and opacity of the painting. (See Set options for paintings and tools.) ）.Choose an option from the Style menu to control the shape of the paint stroke.

For Area, enter a value to specify the area covered by the paint stroke. The higher the value, the larger the area covered and the greater the number of strokes.

For Tolerance, enter a value or drag the slider to limit the area to which the paint stroke can be applied. Low tolerance can be used to draw an infinite number of strokes anywhere in the image. The high tolerance limits the paint stroke to areas that are distinctly different from the colors in the source state or snapshot.

4.Drag in the image to paint.

1. Menu - Window - History pop-up history panel 2. Light up the brush before the step you want to restore, and it's OK.

1. The steps are as follows:

Press the [Ctrl+O] key to open a material image--- execute the Photoshop CS6 menu bar "Blur"-"Gaussian Blur" command to open the "Gaussian Blur" dialog box, set the dialog box parameters, click the "OK" button --- open the Photoshop CS6 "History" panel, click on the left icon of the open history state to make the "Source of History Brush" icon displayed, and set the state to the source of "History Brush". (If you don't have a History panel in the panel area, you can execute the Window-History command to open the Photoshop CS6 History panel.) --Execute Photoshop CS6 menu bar "Filter" - "Stylize" - "Collage"; Keep the default settings in the pop-up collage dialog box, and click the OK button.

-- Set the history brush source in the Photoshop CS6 History panel (the history brush source is the time when you want to restore a part of the image to the selected source image). - Select the Photoshop CS6 Toolbox "History Brush Tool", set the appropriate brush size, and hold down the left mouse button to drag the smear in the part that needs to be restored (such as the face of the person here), and the smeared part will be restored to the state of the image when the selected "History Brush Source" was opened.

2. The main function of Photoshop CS6 history brush tool is to restore part of the image to a certain historical state, which can form a special image effect. The History Brush tool, which must be used in conjunction with the History panel, is used for revert operations, but instead of restoring the entire image to its previous state, it restores parts of the image, allowing for more granular control over Photoshop CS6 images.

Select the History Brush, and then set the source ...... in the History RecordFor example, I fill in black first, then white, and then I use the History Brush to paint with the history of black as the source, and the other soft-edged brushes are the ones with blurred edges.

Open the History panel inside the window and click on the top image.

It's very likely that you create multiple layers and select a layer that doesn't correspond to each other, for example, if you create a transparent layer and then select it, and then you use the history brush Y or shift+y, then the warning you mentioned will pop up.

So switch to the right layer and use it again.

Directly with the history in the window. Then click on the history you want.

I did it too far forward and I can't recover it

Create a snapshot to restore to the snapshot step.

The "object" you are currently working on (modifying) is not based on the basis of the "object"!

Take this sentence seriously!

In fact, it is the historical state "object" error! Replace objects in the panel history!

For example, if you open a ** and zoom it out, the history brush will appear "You can't use the history brush." Tips! Because the object you're currently working on is not in its original state, the "source" has changed!

But after you zoom out - create a new snapshot! On the new snapshot you'll be able to use the History Brush! This new snapshot is your new "source"!

Whenever you make changes to the image size, etc., and you want to use this state as the "source" basis, you have to "create a new snapshot"!

In fact, this is equivalent to the "system restore" function that comes with the computer system, and you need to create a "restore point" to restore!

It's because you didn't specify the source of the painting in the history......

When you open the history panel (Window - History), you'll see a small box in front of the thumbnail at the top and each history step below. Click on the box, and a small icon of the history brush will appear, and this step is defined as the painting source, which means that the image will return to this step after smearing with the history brush.
