uniPDFFrame set zoom in runtime

Set zoom in runtime

How do I set zoom to 50% in runtime

I tried in many ways and I could not.

 

In viewer.html I even set the property as selected to 50%,

But when you finish uploading the pdf back to "auto zoom"

<span id="scaleSelectContainer" class="dropdownToolbarButton">
                     <select id="scaleSelect" title="Zoom" tabindex="23" data-l10n-id="zoom">
                      <option id="pageAutoOption" title="" value="auto" data-l10n-id="page_scale_auto">Automatic Zoom</option>
                      <option id="pageActualOption" title="" value="page-actual" data-l10n-id="page_scale_actual">Actual Size</option>
                      <option id="pageFitOption" title="" value="page-fit" data-l10n-id="page_scale_fit">Fit Page</option>
                      <option id="pageWidthOption" title="" value="page-width" data-l10n-id="page_scale_width">Full Width</option>
                      <option id="customScaleOption" title="" value="custom"></option>
                      <option title="" value="0.5" selected="selected" data-l10n-id="page_scale_percent" data-l10n-args='{ "scale": 50 }'>50%</option>
                      <option title="" value="0.75" data-l10n-id="page_scale_percent" data-l10n-args='{ "scale": 75 }'>75%</option>
                      <option title="" value="1" data-l10n-id="page_scale_percent" data-l10n-args='{ "scale": 100 }'>100%</option>
                      <option title="" value="1.25" data-l10n-id="page_scale_percent" data-l10n-args='{ "scale": 125 }'>125%</option>
                      <option title="" value="1.5" data-l10n-id="page_scale_percent" data-l10n-args='{ "scale": 150 }'>150%</option>
                      <option title="" value="2" data-l10n-id="page_scale_percent" data-l10n-args='{ "scale": 200 }'>200%</option>
                      <option title="" value="3" data-l10n-id="page_scale_percent" data-l10n-args='{ "scale": 300 }'>300%</option>
                      <option title="" value="4" data-l10n-id="page_scale_percent" data-l10n-args='{ "scale": 400 }'>400%</option>
                    </select>

If anyone can help me, I appreciate it.

Hi,

 

If I understand correctly, can you try this approach ?!:

 

For example:

UniPDFFrame1.PdfURL := FUrl + '#page=1&zoom=50';

Best regards,

Not wanting to take up your time ...

 

Could you tell me how do I call the print button without the user having to click on it?

You can try to use this approach:

MainForm.UniPDFFrame1.JSInterface.JSCall('iframe.contentWindow.print', []);

Hi,

I read all the comments. When I use: 

MainForm.UniPDFFrame1.JSInterface.JSCall('iframe.contentWindow.print', []);

It's work wonderful, but the question is: Is there a way to print automatic?

UniSession.AddJS (UnimPDFFrame1.JSName + '.iframe.contentWindow.document.' + 'getElementById ("print").click()');
