How does the ckeditor trigger plug-ins through code - ckeditor4.x

I want to trigger the image plug-in after the insertElement inserts an image. You can directly modify the size of the image by dragging it, rather than clicking the source code before the plug-in takes effect
My version is 4.15. I tried a lot but it didn't work

How to use url image inserting dialog instead of upload in CKEditor 5 Classic

I want to use CKEditor 5, insert image with URL dialog, instead of its default file upload dialog. how to do this in CKEditor 5 Classic?
There is, as far as I know, no such feature officially provided.
There is, however, a tutorial provided in the documentation on how to write such a feature: https://ckeditor.com/docs/ckeditor5/latest/framework/guides/creating-simple-plugin.html
There is also a separate project on github for the same purpose, which appears to be a bit more stylish: https://github.com/khanhna/ckeditor5-image-via-url
Both approaches require to configure a modified build, and both appear to lack an important component: a button in the image's toolbar to edit that URL later on.
So, a more simple approach that does achieve practically the same is to just drag the images into the editor from some browser window.

CkEditor: Image2 (enhanced image) plugin simplified upload process

I am in the process of integrating the Image2 (enhanced image) plugin into my CkEditor.
My use case for this plugin is for allowing users to upload images from local machines to the server.
So far so good, but the default upload process of this plugin has some steps I would like to be able to skip.
For instance, whenever I click the Image button in the editor's toolbar, I'd like the uploader to automatically open the file browser instead of just popping up the standard file managed dialog.
Also, I would like for the upload process to be automatically started whenever the user choodses the image to upload (by default, the plugin requires a click on the "Upload it"/"Send it to the server" button). Actually, I would like to remove the "Upload it"/"Send it to the server" button entirely.
Last but not least, I'd like the dialog to close automatically whenever an image is successfully uploaded.
Feels like almost a no-brainer to me, but I could not find anyone that actually managed to solve this situation, despite the fact that this kind of question has been asked many times around the net in recent years.
Can someone point me in the right direction? thank you.

Quartz Composer Custom Image Kernel XCode 8

I'm interested in testing a custom image filter kernel using Quartz Composer. This seems like it should be possible given the docs (see Figure 9-2):
https://developer.apple.com/library/content/documentation/GraphicsImaging/Conceptual/CoreImaging/ci_custom_filters/ci_custom_filters.html
I have installed Quartz Composer (via the XCode 8 tools), however, I can't find any option that allows me to enter my custom kernel shader code. Does anyone know how to do this?
In quartz composer go to the patch library (Command-Return default shortcut key) search for core image filter. You can load that into composition by double clicking or if its the top of your search hit Return. Click on the patch that you loaded in and go to the patch settings panel (Command-2 default shortcut). Place your code in the text field.
You can drag and drop a image in and wire the output image to your input of your core image filter patch. You need to wire it to a rendering patch to see it rendered in your viewer. Dropping in a billboard will help facilitate that. If you set the billboard's width to 2, it should fill viewers screen.

jQuery-ui draggable element into CKEditor?

I was testing a different feature, and I somehow, accidentally dropped an image that I had rendered "draggable" with jQuery UI, into a CKEditor (jQuery version) window. The source in the editor was updated accordingly. Serendipity!
But it was like I had just seen a unicorn -- It only happened once, and I was not able to replicate the effect.
Has anyone else been able to get those two tools to work together? If so, what's the trick?
I believe you don't need to make an image "draggable" with jquery to drag it into CkEditor. It works out of the box with any image of the page.

How to override WebKit's PDFViewSavePDFToDownloadFolder?

I have an application that includes a WebView, which automatically displays PDFs in WebKits WebPDFView. When the user hovers above the lower portion of the document, an overlay appears that enables zooming, opening in Finder and saving the PDF in the download folder.
I would like to implement the latter, but I have no idea how to go about it, except that I need to implement PDFViewSavePDFToDownloadFolder. However, where do I implement it? I'd appreciate any pointers.
If you want to monkey patch Apple's built-in PDF viewer, you can't unless you want to use a code injection hack that is guaranteed to break. If you want to implement your own PDF viewer, then you build a WebKit plugin.
