-----------------------------------------
yep I faced the same scenario:
PDF Sample:
[https://drive.google.com/file/d/0B9Bp3aFnnsTGTHlYUm5PamZtT2c/view?usp=sharing]
I used this Code:
<code>
org.apache.pdfbox.rendering.PDFRenderer pdrend = new
org.apache.pdfbox.rendering.PDFRenderer(doc);
var img = pdrend.renderImageWithDPI(0, 150);
return Utility.IO.system.ImagetoBin(img.getBitmap());
</code>
here is the exception:
{java.lang.Error: Not Implemented}
[java.lang.Error]: {java.lang.Error: Not Implemented}
