title: How to fix libpng warning when reading interlaced PNG?
body: <p>I am using OpenCV with Visual Studio 2010 to read and display some images(including jpg and png). My program is working fine but sometimes it fails with the following warning :</p>
  <pre><code>libpng warning: interlace handling should be turned on when using png_read_image.
  OpenCV Error: Insufficient memory (failed to allocate 1398604 bytes) in unknown function, file ..\..\..\src\opencv\modules\core\src\alloc.cpp, line 52
  </code></pre>
  <p>I tried searching on the internet for the fix but couldn't get any. Any help regarding the problem would be greatly appreciated.</p>
