Anyway to Create Headers and Footers Such That They Can't Be Selected

canvas.width = 1400
ctx = canvas.getContext("2d");
ctx.font = (canvas.parentNode.scrollHeight / 2) + "px sans-serif"
ctx.fillStyle = 'yellow';
ctx.fillRect(0, 0, canvas.width, canvas.height)
ctx.fillStyle = 'black';
ctx.fillText("section: _SECTION_", 5, canvas.parentNode.scrollHeight / 2);

You will need to edit the various sizes to get it to work well for your conversion.

So, sounds like a combination of the plugin and the code. Buddy, that is WICKED cool!

Yes-yes! WICKED cool indeed!

This is what worked:

PHP Code:

<header>
  <canvas>
  <script>
    canvas = document.currentScript.parentNode;
    canvas.height = 120;
    canvas.width = 1400;
    ctx = canvas.getContext("2d");
    ctx.font = "12px sans-serif";
    ctx.fillStyle = 'yellow';
    ctx.fillRect(0, 0, canvas.width, canvas.height);  
    ctx.fillStyle = 'black';
    ctx.fillText("section: _SECTION_", 5, canvas.height / 2 + 5);

This should help as well:

With that commit, the simplest I can make it is:

<header><canvas style="width: _WIDTH_PIXELS_px; height: _HEIGHT_PIXELS_px;" width="_WIDTH_PIXELS_" height="_HEIGHT_PIXELS_"><script>
canvas = document.currentScript.parentNode
s = window.getComputedStyle(canvas)
ctx = canvas.getContext("2d");
ctx.font = s.font
ctx.fillStyle = 'black';
ctx.fillText("section: _SECTION_", 5, 5 + canvas.height / 2);

That makes it easier, for sure, thanks!

I'm going to play more with it later.

BTW I was curious about the new TTS developments and found that in the latest available preview there's something not working correctly when changing voices. Also, I was asked to restart the PC (Windows OS), but I'm pretty sure I had all Calibre stuff (editor, viewer) already closed before installing. But I may be wrong about this.

The TTS issue is that I have to re-open the book to have the voice change to another one.

Oh, and I forgot to thank you for the pause after sentence setting. It's a very interesting addition.

ctx.fillText("section: _SECTION_", 5, 5 + canvas.height / 2);

upon a quick test I confirm it is working fine, here's the output:
header after new commit - Nineteen eighty-four - George Orwell.pdf

On current version I found these settings to look fine, with a white transparent background and grey text:

PHP Code:

<header>
  <canvas>
  <script>
    canvas = document.currentScript.parentNode;
    canvas.height = 120;
    canvas.width = 1400;
    ctx = canvas.getContext("2d");
    ctx.font = "12px sans-serif";
    ctx.fillStyle = 'transparent';
    ctx.fillRect(0, 0, canvas.width, canvas.height);  
    ctx.fillStyle = 'grey';
    ctx.fillText("_TITLE_", 2, canvas.height / 2 + 3);
    ctx.fillText("_SECTION_", 250, canvas.height / 2 + 3);
    ctx.fillText("_AUTHOR_", 500, canvas.height / 2 + 3); 


PHP Code:

<footer>
  <canvas>
  <script>
    canvas = document.currentScript.parentNode;
    canvas.height = 120;
    canvas.width = 1400;
    ctx = canvas.getContext("2d");
    ctx.font = "12px sans-serif";
    ctx.fillStyle = 'transparent';
    ctx.fillRect(0, 0, canvas.width, canvas.height);  
    ctx.fillStyle = 'grey';
    ctx.fillText("_PAGENUM_/_TOTAL_PAGES_", 260, canvas.height / 2 + 3); 


looks like this:

I've attached the trimmed EPUB I used if someone wants to do further testing

This is with the Piper backend?

[Comfy.n]

Also with legacy. I've tried a portable preview with a fresh profile and the issue didn't manifest at first, however it did after further tests as well either when trying to switch between piper voices or legacy ones.

That fixed for me the issue of a "sticky" voice (wouldn't get changed), although I got the error below upon running TTS initially and also a couple of times when changing voices. Later I'll be able to do more tests.

calibre, version 7.19.101
ERROR: Read aloud failed: piper process failed with exit code: -1073740791 and error messages:

I'm using 7.19 stable version then running this bat script with latest source:

Rem You can run the GUI as
Echo "Minimise this window, Don't Close"

calibre-debug -g 1>> log-dev-%dt%.txt 2>&1

That's the piper binary crashing I doubt that has anything to do with calibre. It's a standalone executable. If you can find a way to reproduce I can try to debug but it doesnt crasha t all for me on my windows system.

[Comfy.n]

I've restarted PC and still got the crash. I suspect it's related to the pt-pt voice named tugão, as it only happens if I have/had it selected.

[kovidgoyal]

That should be reported to the piper project in that case: https://github.com/rhasspy/piper

[Comfy.n]

I've edited piper-voices.json to read tugao instead of tugão, as well as the filenames in calibre-cache and got it to work!

So perhaps piper doesn't like the tilde, or the tug\u00e3o representation.

[kovidgoyal]

See if this fixes it. The voice will be re-downloaded using a pure ascii filename.
