Hey Matthew, is there a way to set a maxwidth for the img tag that is inserted? Or control the image size itself?
I'd like to use for adding signatures to essays etc, but the image that is inserted is 1280 x 720 and way too large for this use case...

I saw a comment about the Sketch icon not visible. Here are my findings:

1. As pointed out earlier, go to /admin/settings.php?section=atto_sketch_settings and check the box "If checked the sketch will be saved as a standard image upload instead of a base64 inline image."

2. However, when you do this, the Sketch icon disappears from the toolbar menu. In the quiz setting--> Response Options, set the Response format as “HTML editor with file picker” instead of “HTML editor” and it should work well.

I am on Moodle 3.9 and tested this on Firefox.

@Matthew: Any plans to upgrade the plugin to 3.10?

This is great! But I cannot use it with my k-12 students. Is there a way to turn safe search on for the pixelbay image search or disable the button?

@Nicholas Fahey In sketch/css/layout.css add the following:

span#media {
display: none;
}

I just installed it, but when I preview the question, I can't seem to find the Sketch Icon. Am I supposed to do anything else beyond installing this plugin, to make it working ? Thanks

@Roberto Catanuto You must also add "sketch" to the list of plugins added into each text editor.

@MatthewDavidson yes I already did it.
In this page https://personal-site.org/admin/settings.php?section=editorsettingsatto, I added the line "sketch = sketch".
I can see the plugin's icon in the following boxes of the question editing page: "Question text", "General feedback", "Grader information". It is not visible in "Response template" and more importantly in the preview of the question that will be shown to students.

@Anirudh-Phadke your suggestion works. Thanks. Anyway, when I give students a question with a response template having a background picture, Sketch refuses to save the picture after the students edited it. Any ideas ?

I've just tested and it worked for me. Can you tell me the image type (jpg, png, gif) and the size of the template (height and width)?

Hi, please could you update the supported version number for moodle to moodle 4. This means that each week when we update moodle, the extension will automatically install. Currently, you have to install it manually which takes time. Thank you so much.

Hello,
I tried sketch on the iPad but could not use several functions like the eraser. Is it possible to draw on a background image?

Thanks!

@Erbil Yilmaz I just tested it on an iPad, it does work, however when wanting to open an image I have to put the cursor beside the image instead of selecting the image. I'll try to look into IOS compatibility issues like this.
