javascript - Fabricjs - setBackgroundImage to Empty URL causes null reference error in _setWidthHeight -


I found an article explaining how to clear the background of the canvas ...

Canvas.setBackgroundImage ('', canvas.renderAll.bind (canvas));

I have created an online design tool that uses Fabric 1.4.4 and includes a lot of functionality but can not know for my life what I am doing wrong here I canvas real image Can set in the URL and it is displayed correctly, but when I used the code to remove the background picture (shown above) I would like Fabricz S gets a JavaScript error:

Unused exception line 16045, in column 7 ... / fabric.js

0x800a138f - JavaScript runtime error: undefined or empty reference property Unable to get 'width'

The line refers to the _setWidthHeight method

Am I doing something wrong? It seems that it should be quite straight forward, but I can not remove the background image ... whether it exists or not.

  canvas.Sizebacksize (0, post-less "itemprop =" text "> 
 canvas.renderAll.bind (canvas));   
 It works for us, Regards, Benike

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise.

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
