This example will show you how to load an image using evas and fill a swallow with it.

It\textquotesingle{}s basically almost like the last example, but with a minor change.

This variables are used to store the name of the image that is going to be used, the path to it and a variable that will store the error cause if something goes wrong.

Here it is\+:  
\begin{DoxyCodeInclude}
   \textcolor{keyword}{const} \textcolor{keywordtype}{char}  *edje\_file = PACKAGE\_DATA\_DIR\textcolor{stringliteral}{"/swallow.edj"};
   \textcolor{keyword}{const} \textcolor{keywordtype}{char}  *img\_file = PACKAGE\_DATA\_DIR\textcolor{stringliteral}{"/bubble.png"};
   Evas\_Load\_Error err;

\end{DoxyCodeInclude}


Then we load the image with this command\+:


\begin{DoxyCodeInclude}
   img = evas\_object\_image\_filled\_add(evas);
   evas\_object\_image\_file\_set(img, img\_file, NULL);

\end{DoxyCodeInclude}


To check if we had some problem we use\+:


\begin{DoxyCodeInclude}
   err = evas\_object\_image\_load\_error\_get(img);

   \textcolor{keywordflow}{if} (err != EVAS\_LOAD\_ERROR\_NONE)
   \{
      fprintf(stderr, \textcolor{stringliteral}{"could not load image '%s'. error string is \(\backslash\)"%s\(\backslash\)"\(\backslash\)n"},
              img\_file, \mbox{\hyperlink{group__Evas__Utils_gaca3384642e5ebb32cfeab24c760c739a}{evas\_load\_error\_str}}(err));
     \textcolor{keywordflow}{goto} shutdown\_edje;
   \}

\end{DoxyCodeInclude}


Now we are going to swallow it and check if worked. If you notice we are using \char`\"{}part\+\_\+one\char`\"{} as argument. We do this because we must explicit what part of our .edc file we want to swallow\+:


\begin{DoxyCodeInclude}
   edje\_object\_part\_swallow(edje\_obj, \textcolor{stringliteral}{"part\_one"}, img);

   obj = edje\_object\_part\_swallow\_get(edje\_obj, \textcolor{stringliteral}{"part\_one"});

   \textcolor{keywordflow}{if}(obj == img)
      printf(\textcolor{stringliteral}{"Swallowing worked!\(\backslash\)n"});

\end{DoxyCodeInclude}


The example\textquotesingle{}s window should look like this picture\+:

  
\begin{DoxyImageNoCaption}
  \mbox{\includegraphics[width=\textwidth]{swallow2final}}
\end{DoxyImageNoCaption}


The complete .edc file\+: 
\begin{DoxyCodeInclude}
collections \{
   group \{
      name: "example\_group";
      max: 500 500;
      min: 50 50;

      parts \{
         part \{
            name: "part\_one";
            type: SWALLOW;
            description \{
               min: 50 50;
               state: "default" 0.0;
               rel1.relative: 0.0 0.0;
               rel2.relative: 1.0 1.0;
            \}
         \}
      \}

   \}
\}
\end{DoxyCodeInclude}
