title: ImageMagick - Order of command option 'Alpha Activate' used along with resize or flatten causes blank image in Version 7
body: <p>We are migrating from ImageMagick 6 to ImageMagick 7, but using the same command line option used in version 6 is now giving a blank image in version 7. The command used is</p>
  <blockquote>
  <p>convert &quot;C:\Imagemagick\beige.png&quot; -alpha Activate -scale 640x640
  &quot;C:\Imagemagick\Out\Zoom.jpg&quot;</p>
  </blockquote>
  <p>The input &quot;beige.png&quot; does not have an alpha channel. But if I input an image with alpha channel, it creates a file with valid results. Also, if I set the option &quot;-alpha Activate&quot; after scale operation it gives a valid result. Do we need to consider any order while setting the alpha for ImageMagick 7 version?</p>
