Thank you for your comment. I made the change that removes the .. because I found in my testing that it didn't work in some places of Moodle. I'll look into it today and see what I can do about the path.
a) But sometimes, mostly when de image is large, only a portion in shown, the rest of the canvas is blank /(white). it seems like a curtain NOT descending.
b) When the image is small and NOT fills the canvas, the generated image is not cropped, there is a lot of bank space
Where can I change the dimensions of the javascript dialogue and canvas in code?? I've tried the css included but without success.
But I have realized a problem that's a showstopper for us.
Sketch works well on pages managed by teachers. It works also on forum posts, and the raw data is saved to database. BUT on display the content is filtered out by format_text() function in forum_print_post(). The only way to show it in the discussion page is to use "noclean". That's not acceptable for a production site.
As I commented, we are interested on Sketch as an image annotator. Te purpose is to allow students (or teachers) to add marks and signs to an existing image. I'lve lived a s a teacher many moments of "ahh, I'd it in front of my eyes without knowing where to look at" by students. So, having Sketch working in forum pages is a must.
In addition. Currently Sketch return a base64 encoded text embedded, That may scare most users, in my opinion. Both problems would be solved if the return from Sketch would be a file in the editor area, and a link to that in the editor text ¿Is that possible, feasible?
I would like to use Sketch for a maths test. Nevertheless, the image created with sktech in a "comment question" (Test Plugin") appears in the preview BUT NOT in the final answer that has to be noted by the teacher.
Do you have a solution? Is it an editor problem?
But that cleaning is there for a reason. Input from students, even form teachers, MUST be cleaned. People tend to copy-paste any type of things. We have had some incidents with teachers inadvertently pasting hidden malicious scripts, or just inconvenient advertisements.
A much better way to deal with the issue would be to store the image file in the editor draft filearea. But it's a significant more work, I understand.
I have not altered the setup in any way. I was using Firefox as my browser.
