Can't display Pagenumber in Footer with custom Font

[WinkiG]

I'm using the Custom-Font Arial in my document
the Font displayes correctly in the whole document except the Footer.

heres the relevant part of my ts

pdfpage = PAGE
pdfpage.typeNum = 28032014

pdfpage.config {
		disableAllHeaderCode = 1
		xhtml_cleaning = 0
		admPanel = 0
		debug = 0
		disablePrefixComment = 1
}

pdfpage.20 = COA
pdfpage.20  {
     15 < tt_content.list.20.eventpdf_eventpdf
}
	plugin.eventpdf {
		view {
			templateRootPaths >
			templateRootPaths {
				0 = EXT:eventpdf/Resources/Private/Templates/
			}
		}
	}
.....
	plugin.tx_pdfviewhelpers.settings.generalText.fontFamily = arial
	plugin.tx_pdfviewhelpers.settings {
		config.fonts {
			addTTFFont {
					arial {
							path = EXT:eventpdf/Resources/Public/Fonts/arial.ttf		
....

text.types.footer {
color = #888
fontSize = 14
fontFamily = arial
}

and my html of the footer:

	<pdf:footer>
			<pdf:text type="footer">Seite {pdf:getPageNumberAlias()} von {pdf:getTotalNumberOfPagesAlias()}</pdf:text>
	</pdf:footer>

heres the output:

this happens only when i include the Viewhelpers in the footer. normal text ist displayed correctly. and the viewhelpers are also working correctly when used anywhere else...

TYPO3 version(s): 10.4.20
pdfviewhelpers version: 2.3.5

@WinkiG Thanks for your bug report! I had a look at the issue and I can easily reproduce this with a simple example:

<pdf:document>
    <pdf:page>
        <pdf:text fontFamily="roboto">{pdf:getPageNumberAlias()}</pdf:text>
    </pdf:page>
</pdf:document>

It seems to be an issue with the order in which we do the rendering in the AbstractTextViewHelper.php and is not directly related to the footer. When I move the call $this->getPDF()->SetFont to the beginning of the method (just before $this->renderChildren()), the problem is solved for my example. If we set the font after $this->renderChildren() it seems to create the page number alias with the wrong font.

Can you try to apply the following patch and test whether that works for you?

However I will have to further investigate the issue to find out whether that is already the proper solution.

@maechler thanks for the fast reply.
