Introduction<\/h2>\n

You may run into problems saving even medium size diagrams or ones with a high zoom level. This article describes some ways of dealing with this.<\/p>\n

PDF<\/h2>\n

Issues with saving a single-page PDF and the solutions are described at Single Page PDF of a Diagram<\/a>.<\/p>\n

PNG (Or Other Image Formats)<\/h2>\n

You may get this dialog:<\/p>\n

\"\"<\/p>\n

or you may just want to have more control. Below are several options you can try. They can likely be modified for other image formats, but\u00a0PNG\u00a0is used here.<\/p>\n

Print with a PDF Creator that Also Saves Images<\/h3>\n

PDF Creator<\/a> will also save PNG and other formats instead of PDF. It avoids the issues with saving via  Diagram > Save As… <\/a> in \u0192h<\/span><\/span>. How to use PDFCreator to create a PDF is described at Single Page PDF of a Diagram<\/a>. Follow those instructions, but in the save dialogs that come when printing, choose PNG instead of PDF.<\/p>\n

Note that you should use File > Print Setup<\/a> to set up the pages, and check that they are what you want using File > Print Preview<\/a> before printing with File > Print<\/a>. You may have to move the diagram around to get it in a single page.<\/p>\n

By default the dpi will be 150. You can change this by editing the profile under the\u00a0Profiles\u00a0tab in PDFCreator. Change the one for\u00a0Convert.<\/p>\n

This method has been used to get 300 dpi\u00a0PNG\u00a0images of 16′ diagrams. There may be a limit of 200″. It should work for smaller diagrams, and gives you more control of your output image than the options in Family Historian.<\/p>\n

Extract the Image from a PDF<\/h3>\n

You can in general extract an image from a PDF, such as those created by Family Historian PDF or the PDF tools described in Single Page PDF of a Diagram. This page describes one way to do that using GhostScript.<\/p>\n

GhostScript<\/h4>\n

You must install GhostScript from\u00a0 Ghostscript for Windows (32 bit)<\/a>. The following was done with an old version of GhostScript. The details may have to be changed for a newer version.<\/p>\n

The command line is<\/p>\n

C:\\Program Files\\gs\\gs9.20\\bin\\gswin64c -dNOPAUSE -dBATCH -r<resolution> -sDEVICE=png16m -sOutputFile=\"<your-output-file-name> <your-pdf-file-name>\"<\/code><\/p>\n

Use the path to\u00a0GhostScript\u00a0appropriate for the version you have installed. Use 300 for the resolution unless you have reason to use something else. Specifying a higher resolution than is in the PDF will not be useful.<\/p>\n

In my case I wrapped the\u00a0GhostScript\u00a0command in a\u00a0C#\u00a0console app. The reason is that you can use the\u00a0Open With\u00a0menu in\u00a0File Explorer\u00a0on a\u00a0PDF\u00a0file, and it will then appear in the\u00a0Open With\u00a0menu next time, making it easy to use. I use\u00a0C#\u00a0as it makes a .exe and appears more attractive in the Open With menu. You could just as well use a\u00a0BAT\u00a0file,\u00a0PowerShell\u00a0script,\u00a0Java JAR, or other. In those cases the file extension appears in the\u00a0Open With\u00a0menu.<\/p>\n

My\u00a0C#\u00a0application can be found at\u00a0https:\/\/github.com\/KennethEvans\/VS-ConvertPdfToImage<\/a>. The\u00a0GhostScript\u00a0location and output directory is hard-coded and would need to be changed.<\/p>\n

I have used this program for many years for other uses and it seems to work. The heavy lifting is done by\u00a0GhostScript, of course, not my application, which is very simple.<\/p>\n[Written by Kenneth Evans]\n","protected":false},"template":"","fh_version":[13,14,15,739],"skill_level":[17],"topic":[724],"class_list":["post-11177","kb_article","type-kb_article","status-publish","hentry","fh_version-v4","fh_version-v5","fh_version-v6","fh_version-v7","skill_level-intermediate","topic-diagram-tips"],"_links":{"self":[{"href":"https:\/\/www.fhug.org.uk\/kb\/wp-json\/wp\/v2\/kb_article\/11177","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.fhug.org.uk\/kb\/wp-json\/wp\/v2\/kb_article"}],"about":[{"href":"https:\/\/www.fhug.org.uk\/kb\/wp-json\/wp\/v2\/types\/kb_article"}],"wp:attachment":[{"href":"https:\/\/www.fhug.org.uk\/kb\/wp-json\/wp\/v2\/media?parent=11177"}],"wp:term":[{"taxonomy":"fh_version","embeddable":true,"href":"https:\/\/www.fhug.org.uk\/kb\/wp-json\/wp\/v2\/fh_version?post=11177"},{"taxonomy":"skill_level","embeddable":true,"href":"https:\/\/www.fhug.org.uk\/kb\/wp-json\/wp\/v2\/skill_level?post=11177"},{"taxonomy":"topic","embeddable":true,"href":"https:\/\/www.fhug.org.uk\/kb\/wp-json\/wp\/v2\/topic?post=11177"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
