A parent passes it’s state to a child via props. The child is not allowed to change its parents state, if a child wants to change a parents state then the parent passes a callback to the child that the child can call to change the state. This is fundamental to reacts state management. A child does not need to know how a parent stores it’s state (class instance, hook instance or state library).

if your application uses a global state manager like redux, then global state is mapped to props and a store action can be called to update global state. In this case the child does not need to know who else is using the state because it’s global.

Fix following part. Image drawing should be in image's onload callback.

You have a typo in your code theme: whiteTheme -> theme: whiteTheme,

Here is the working example.

Ciao, I think you could blob your image modified, then save it to localStorage and, when user exit from preview mode, show image blobbed instead of original photo.

I try to explain better: lets say you have this image in preview mode and user zooms it. So now original image is modified. Then, user clicks Clear Preview button. Just before call setIsPreviewMode(false) you could store modified image using, for example, dom-to-image. Something like:

You can use a regex to extract all the number values from the transform-string and then put them back in after you've inverted/mirrored them:

visual studio: copy *.pdb of the project references from some directory to TargetDir

I think the main issue is that you did not define the custom property Pr21DllDir and Product21SymbolsFolder in your xxx.csproj file which I have not seen those properties in your file. So when you execute these command, MSBuild unable to identify $(Pr21DllDir) and $(Product21SymbolsFolder).

Solution

You can try these:

I checked the file tui-image-editor.js for download function as suggested by gaetanoM.

The solution is to call for base64 string of the edited image. The base64 string starts after the data:image/png;base64, prefix.

I give my answer to this hoping this will help someone in the future.

I too faced this issue and solved issue with answer from this link

Here is my script section!

TL;DR:
Here is a working fiddle: https://fiddle.sencha.com/#view/editor&fiddle/2p0o

Long version:

There are four problems:

• You need to load an initial image, otherwise you can't use the editing controls.
• You need to wait until the image editor object is ready before calling loadImageFromURL, otherwise you may get an error or a silent failure
• When the image is loaded you need to tell the image editor the new size, otherwise the image will be hidden or sized incorrectly.
• If you load an external image, the external server has to set the Access-Control-Allow-Origin header and explicitly allow your domain to access it, otherwise the image editor can not access it.

This first problem can be solved by loading a blank image like this:
