Christopher Chedeau	c2a3b67ccc	Fix scrollbar (#735) ... The computation was not correct. I'm not really sure how it used to work but it was not taking into account the dimensions of the scene so it was wrong. The new algorithm is computing the scrollbar such that it's the position of the viewport in relationship to the bounding box of the viewport and all the elements. Fixes #680	5 years ago

Christopher Chedeau	2dd1796351	Add encryption (#642) ... * Add encryption In order to avoid the server being able to read the content of the scene, this PR implements local encryption and decryption. This implements the algorithm described in #610. Right now the server doesn't support uploading binary files. I mocked the server with comments. @lipis, could you add support on the server and update this PR? I added a bunch of TODO: that tell you where to comment/uncomment in order to get the server flow going. To test locally right now: - Import: Open http://localhost:3000/#json=1234,5oYVOnGpWYPPTz19-PMYYw and see a square - Export: Click the export link and see the right url with the private key + the encrypted binary in the console Fixes #610 * backend_v2 * v2	5 years ago

Christopher Chedeau	be97bd980e	Add button when scrolled outside of visible area (#643) ...

Christopher Chedeau	e1ed40be65	Fix exported size when drawing to the left (#575) ... If you scroll and draw to the left of the origin, when you export the scene, there's a weird whitespace on the right.

Christopher Chedeau	61f301c3e0	Cleanup saved json file (#578) ... It turns out the only thing we need to save in the appState is the background color. All the rest is transient data. I added `"type": "excalidraw"` at the beginning to explain where it was. I removed `"source": "http://localhost:3000/"`. I don't think we want to leak on which webpage it was saved from. I removed `isSelected` from the json I added indentation so it's easier to read the content. I'm not 100% sure on this one, but I figure filesize doesn't matter too much those days. And if we want to shrink it, there are more effective ways than json.	5 years ago

Mike Lewis	5ce5e5ac1e	Adjust type of data URI when saving (#452) ... Previously the type used for the data URI when saving was text/plain. On iPad, this caused the file to automatically have a .txt extension added (so files ended up with names like "drawing-xyz.json.txt"). This meant that the files couldn't be loaded by the tool, which expects only files with a .json extension. Now, the type used is application/json, which means that the files get saved with the correct extension and can be successfully loaded on iPad.	5 years ago
