This removes the dependency on a `PDFViewer` instance from the find
controller, which makes it more similar to other components and makes it
easier to unit test with a mock link service.
Finally, we remove the search capabilities from the SVG example since it
doesn't work there because there is no separate text layer.
Now it follows the same pattern as e.g., the document properties
component, which allows us to have one instance of the find controller
and set a new document to search upon switching documents.
Moreover, this allows us to get rid of the dependency on `pdfViewer` in
order to fetch the text content for a page. This is working towards
getting rid of the `pdfViewer` dependency upon initializing the
component entirely in future commits.
Finally, we make the `reset` method private since it's not supposed to
be used from the outside anymore now that `setDocument` takes care of
this, similar to other components.
This patch:
- resolves a warning in the console about missing character encoding;
- makes the viewer use the same background color and PDF file as the
regular viewer;
- simplifies the example to bring it more in line with the other
examples.
Re: issue 7017.
This should prevent the error, but does not fix the broken rendering.
The rendering issues are caused by `svg.js` not supporting the various text rendering modes, in this case specifically "invisible" (as indicated in the console `Warning: Unimplemented method setTextRenderingMode`).
Compared to the canvas case, where we just ignore invisible text, a smarter solution is probably required for the SVG case. Since just ignoring invisible text in `svg.js` would mean that text-selection isn't possible.
