Add support "data:image/gif;base64" like svg in img tag

[syjer]

hi @TomySmit , it's already supported as far as I know.

See

openhtmltopdf/openhtmltopdf-pdfbox/src/main/java/com/openhtmltopdf/pdfboxout/PdfBoxReplacedElementFactory.java

Line 89 in 9343409

FSImage fsImage = uac.getImageResource(srcAttr).getImage();

where it call:

https://github.com/danfickle/openhtmltopdf/blob/open-dev-v1/openhtmltopdf-pdfbox/src/main/java/com/openhtmltopdf/pdfboxout/PdfBoxUserAgent.java#L75 which load the base 64 encoded image.

There may be a problem if base64 string has a space before, e.g.

data:image/png;base64, iVBORw0... - will not render an image, because constructor of URI throws exception here -

openhtmltopdf/openhtmltopdf-core/src/main/java/com/openhtmltopdf/swing/NaiveUserAgent.java

Line 410 in b98f5b8

URI possiblyRelative = new URI(uri);

data:image/png;base64,iVBORw0... - will render correctly

@roman0x58 interesting, I guess that we need to handle the data uri in a more robust way.

I'll provide a PR to handle this case :D

Fixed with PR provided by @syjer. Re-open as required.
