&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;== FAQ ==&lt;br /&gt;
;Can I open a board without the extension?&lt;br /&gt;
:Yes. A &amp;lt;code&amp;gt;.whiteboard&amp;lt;/code&amp;gt; file is a PNG image. Rename it or a copy of it to &amp;lt;code&amp;gt;.png&amp;lt;/code&amp;gt; and open it in any image viewer. See [[LightweightWhiteboard:Files and Saving|Files and Saving]].&lt;br /&gt;
&lt;br /&gt;
;Can I move a line or shape after drawing it?&lt;br /&gt;
:No. Everything you draw goes straight into the image pixels. There are no objects or layers. Use undo to take a step back. Only an inserted image can be moved and resized, and only until it is placed. See [[LightweightWhiteboard:Images|Images]].&lt;br /&gt;
&lt;br /&gt;
;Can I change the size of a board?&lt;br /&gt;
:Not in the board. New boards get their size from &amp;lt;code&amp;gt;vscWhiteboard.defaultWidth&amp;lt;/code&amp;gt; and &amp;lt;code&amp;gt;vscWhiteboard.defaultHeight&amp;lt;/code&amp;gt;. Change these settings before you create the board. See [[LightweightWhiteboard:Commands and Settings|Commands and Settings]].&lt;br /&gt;
&lt;br /&gt;
;Why does the eraser paint white on my PNG?&lt;br /&gt;
:The eraser always paints white. It does not make pixels transparent. The same applies to &amp;#039;&amp;#039;Clear board&amp;#039;&amp;#039;. See [[LightweightWhiteboard:Drawing Tools#Eraser|Drawing Tools]].&lt;br /&gt;
&lt;br /&gt;
;Can I write text on the board?&lt;br /&gt;
:There is no text tool. You can write with the pen or insert an image that contains text.&lt;br /&gt;
&lt;br /&gt;
;Where are my own colors stored?&lt;br /&gt;
:In the user setting &amp;lt;code&amp;gt;vscWhiteboard.customColors&amp;lt;/code&amp;gt;. They are not stored in the board file and are the same in every workspace. See [[LightweightWhiteboard:Colors|Colors]].&lt;br /&gt;
&lt;br /&gt;
;Is the UI available in other languages?&lt;br /&gt;
:No. Since version 1.1.0 the board is in English only. Version 1.0.0 also had a German UI.&lt;br /&gt;
&lt;br /&gt;
== Troubleshooting ==&lt;br /&gt;
;Dropping an image from the Explorer or the desktop does nothing.&lt;br /&gt;
:Hold &amp;lt;code&amp;gt;Shift&amp;lt;/code&amp;gt; while you drop. Without it VS Code handles the drop itself and opens the file in a new editor instead of passing it to the board. See [[LightweightWhiteboard:Images#Drag and drop|Images]].&lt;br /&gt;
&lt;br /&gt;
;&amp;#039;&amp;#039;This is not an image that can be inserted.&amp;#039;&amp;#039;&lt;br /&gt;
:The dropped or pasted data could not be read as an image. Check the format against the list on the [[LightweightWhiteboard:Images#Supported formats|Images]] page. When dragging from a web browser, try dragging the image itself instead of a link to a page.&lt;br /&gt;
&lt;br /&gt;
;&amp;#039;&amp;#039;Not an image&amp;#039;&amp;#039; when dropping from a browser.&lt;br /&gt;
:The web server did not return an image for that address, for example because the link points to a web page or a login is required. Save the image to disk first and insert the file.&lt;br /&gt;
&lt;br /&gt;
;&amp;#039;&amp;#039;The file could not be read as an image.&amp;#039;&amp;#039;&lt;br /&gt;
:The file is not a valid PNG. The board shows a blank board instead. Saving would overwrite the file with that blank board. Close the tab without saving if you want to keep the file.&lt;br /&gt;
&lt;br /&gt;
;The keys for the tools do not work.&lt;br /&gt;
:Click on the board first. The keys do nothing while a text field, for example the hex field in the color dialog, has the focus.&lt;br /&gt;
&lt;br /&gt;
;A PNG still opens in the normal image preview.&lt;br /&gt;
:That is the default. Use &amp;#039;&amp;#039;View: Reopen Editor With...&amp;#039;&amp;#039; and choose &amp;#039;&amp;#039;Whiteboard (edit PNG)&amp;#039;&amp;#039;, or set &amp;lt;code&amp;gt;workbench.editorAssociations&amp;lt;/code&amp;gt;. See [[LightweightWhiteboard:Commands and Settings#Editors and file types|Commands and Settings]].&lt;br /&gt;
&lt;br /&gt;
;Undo does nothing on a very large board.&lt;br /&gt;
:The history keeps up to about 384 MB of image data per board. Older steps are dropped when it gets larger. After &amp;#039;&amp;#039;Revert File&amp;#039;&amp;#039; the history starts empty, so steps from before the revert cannot be undone.&lt;br /&gt;
&lt;br /&gt;
;&amp;#039;&amp;#039;The whiteboard did not respond in time.&amp;#039;&amp;#039;&lt;br /&gt;
:Saving waited 30 seconds for the board to hand over its image and got no answer. The file was not written. Try to save again.&lt;br /&gt;
