html - W3C Grayscale SVG Filters -


I'm trying to change the W3C greyscale filter found here:

This ridiculous on webkit It's simple, but I'm also using it only because Gecko only supports filtering through filters: url (filter.svg) in CSS. I do not have much experience with SVG, and many times I have messed with them, they were very clear in percentage, but it is a bit more complicated with grayscale.

So here's the code SVG file. 

  & lt; Svg xmlns = "http://www.w3.org/2000/svg" & gt; & Lt; Filter ID = "Grayscale" & gt; & Lt; FeColorMatrix Type = "Matrix" value = "0.3333 0.3333 0.3333 0 0.3333 0.3333 0.3333 0.3333 0.3333 0.3333 0 0 0 0 1 0" /> & Lt; / Svg & gt;   
 In particular, I'm looking at it for grayscale up to 90%, so that only 10% of color is visible, but I do not know how this filter works. I found this document here which is considered to be understood   
 
 
 An easy way to do this is just to use The saturation type for FeColorMatrix (although the mathematics you want to calculate with is not that hard - if you can arithmetic, then you should be able to follow that device.)  
  & Lt; Svg xmlns = "http://www.w3.org/2000/svg" & gt; & Lt; Filter ID = "Grayscale" & gt; & Lt; FeColorMatrix type = "saturated" value = "0.10" /> & Lt; / Svg & gt;

Java - Error: no suitable method found for add(int, java.lang.String) -

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. To clarify - this will not be a method error because it is a linked list. There should not be any way involved. import java.awt. *; Import java.awt.event. *; Import javax.swing. *; Import java.util. *; Import java.util.Scanner; Import java.util.LinkedList; Public class TopTenList JFrame {Private TopTenList tt; See the Private JTextArea list; Private JTextField cmdTextField; Private JTextField resultsTestfield; // This GUI window is the code for the public toptist...

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...
