MD-parola 3 zones but 3rd zone to scroll over all matrixes

Still learning about matrix and MD_ range of powerful libraries

In the documentation it tells me that Zones cant over lap. So what I am trying to do just may not be possible.

I have 4 matrix set up as 2 zone to run a clock like this

  // Two zones with differant fonts
  P.setZone(0, 0, 0);         // for seconds
  P.setZone(1, 1, 3);         // for hh:mm
  P.setFont(0, numeric7Seg);  // small font 3x5
  P.setFont(1, numeric7Se);   // bigger font 4x7
  P.displayZoneText(0, szsecond, PA_LEFT, SPEED_TIME, PAUSE_TIME, PA_PRINT, PA_NO_EFFECT);
  P.displayZoneText(1, szTime, PA_CENTER, SPEED_TIME, PAUSE_TIME, PA_PRINT, PA_NO_EFFECT);
  P.setIntensity(1);
  getTime(szTime);

The clock works well. Zone 0 has small font to show seconds and Zone 1 to show HH:MM with a larger font.

I have been trying and failing to clear all zones and scroll text over all four matrix with a large font. I don't think the suite of MD_XXXX (MD_Max72xx, MD_parola, MD_MAXpanel) will allow me to do this. Is it possible with MD_xxxxxxx.?

Or should i be looking at clearing the screen then using a function to scroll the text and then acall MD_Parola to show the clock again using both fonts.

I've looked through all the MD_xxxxxx libraries, but could not find what I am looking for, so assume it cant be done without a separate function to scroll the text .

You can dynamically change the number of zones. There is an example that shows that. In your case you start with 2 zones, then when you want to scroll the message over all set it to one zone only until the animation is completed, then set it back to 2 zones. You can change the number of zones any time.

Thanks i will have a look over the weekend. I will relook though your examples.

I have been looking into your excel spreadsheet and the fonts.

I notice that the 3x5 fixed small fonts are all positioned so that the empty space is at the bottom, 3 rows.

Is there a way in your Libs to position your font within the 8 rows if space is available say have one blank row top and two bottom?

Define a new or modify and existing font.
