• which have the on hover blurb …
  

  One click uses hover 2x zoom afterwards … more for larger zoom … right click for no zoom

  … which is just to say that the more clicks in a row of the button, the more resultant zoom goes into an onmouseover “hover” over that intermittently shown “circle” or “polygon” rectangle clip-path affected image (ie. img) overlay element placed according to the 2x set of user right click sets (for non-mobile) or double click sets (for mobile) the user subsequently makes on the GeoJson world map above these new buttons

… that, if actioned by the user, ends up with an “augmented reality” (in what we like to think of as a Who Framed Roger Rabbit_esque (or is that a “reverse Who Framed Roger Rabbit_esque“) approach which happens, at least for us, when you overlay some more realistic media over a representation of that “realia” with the same scale) if you’ll pardon any “jargon clash” here?!

As such, onto the recent Region Picker Area of Interest Tutorial we have a changed latest draft Region Picker for you to try all this out.

Previous relevant Region Picker Google Translate Tutorial is shown below.

We wanted to improve the internationalization credentials of our Region Picker web application, of recent times, adding to the progress of yesterday’s Region Picker Revealed Iframes Tutorial. As such, we turn to another great Google product called Google Translate to translate …

• heading text and some button text … and …
• country names

… this Region Picker being a suitable candidate for a “whole of webpage” Google Translation for a URL such as (this Dutch translation version below) …


https://www-rjmprogramming-com-au.translate.goog/HTMLCSS/regions_via_countries.htm?_x_tr_sl=en&_x_tr_tl=nl&_x_tr_hl=en-GB&_x_tr_pto=nui


… or use the language dropdown to the right below …

Yes, we wrote a regions_via_countries.htm version of our Region Picker especially for the occasion, because there are nuances among innerHTML and innerText of elements, that need to be considered, while the changed latest draft Region Picker gets given a new “languages” dropdown element that hangs around long enough to translate from English, via Google Translate, should the user wish to do so. Once there in another language, alas, some of the Geographics based inhouse menu options cannot be achieved.

Previous relevant Region Picker Emoji Flags Tutorial is shown below.

Regular readers will know that we are keen on emojis …

• regarding their way to attract attention
• internationalization assistance
• text (content) that is (like a) graphic (display)

… for we “graphically challenged”, shall we say? We think our Region Picker from yesterday’s Region Picker Geo Chart Image Chart GeoJson Tutorial could do with a little “emoji flag” help. Yes, every country with an ISO-3166 two character code associated with it, can have an associated emoji flag via a Javascript function like …


function orflag(thiscc) {
var lri='ABCDEFGHIJKLMNOPQRSTUVWXYZ';
var dri=['127462','127463','127464','127465','127466','127467','127468','127469','127470','127471','127472','127473','127474','127475','127476','127477','127478','127479','127480','127481','127482','127483','127484','127485','127486','127487'];
var ccsuff='', ccchar=' ', cde='';
for (var iccsuff=0; iccsuff<thiscc.length; iccsuff++) {
ccchar=thiscc.substring(iccsuff, eval(1 + eval('' + iccsuff))).toUpperCase();
ccsuff+=String.fromCodePoint(dri[eval('' + lri.indexOf(ccchar))]); //'&#' + dri[eval('' + lri.indexOf(ccchar))] + ';';
cde='.';
}
return ccsuff;
}


It might have been the recent work with our “rectangle of letter hashtag navigation breadcrumb emojis” in yesterday’s Region Picker Geo Chart Image Chart GeoJson Tutorial that spurred us on, because the keen observer can look at the code above, and if they are “number orientated” they’ll tee up those “1274xx” numbers with ones below. Can you believe that these Regional Indicators have a dual purpose for us now …

1. singly they are helping with the breadcrumbs
2. two together in the form of a country ISO-3166 two character code and they (we kind of think, miraculously) turn into the national flag (emoji) for that country

? And mixing these up into the content mix, we do not have to be quite so sheepish about all the English assumptions in the changed latest draft Region Picker.

Also, we think, it is clarifying the “dropdown” element in the Region Picker, contextualizing the right hand side as the “business end” of proceedings, which can have an “independent life” from “the work in progress” status of what goes on in that dropdown element (which, on non-mobile, is far more “jittery” because it responds to the “onmouseover” events going on).

Did you know?

Personally, we know of some products set up before there were emojis, and requiring flags for their functionality. Sadly, they resorted to individual image files required for each country’s flag … these days with the “emoji flags” this amounts to being an awkward arrangement to maintain, and we Linux web server managers go bananas regarding such a waste of “inode numbers” … because, the last time we looked, “inode numbers” do not grow on trees!

Another realization occurred to us regarding the wait a user had when using the Region Picker and trying to (on a non-mobile platform) right click a country name link (to release “The Whole Shebang”). We realized that that “letter block” we used to create dynamically always had the same content, so why not make it some static HTML, as per …

As a programmer, we recommend “some chill” when re-orienting the device can be possible, but if there is a way to avoid the issues in the first place, count us in as programmers interested in solutions. So we spent a day in amongst the pixels, with some nitty gritty, further to yesterday’s Region Picker Mobile User Experience Tutorial mobile platform user experience start, and …

• turned the “breadcrumb” style ascii letter links into emoji links (and so “I” got the same width as “W”) … and …
• even added line feeds to some “a” country name links to help out so that background image overlapping happens less often to their left … and …
• added country name to rightmost “Image Chart Map Chart” button wording … and …
• played around with tablet and phone platform background-position (of the country image chart) images …

? And don't you find interesting with all this additional functionality, we've not touched the GeoJson World Map web application (being hosted in the Regional Picker iframe all this time), at all?! We also enjoy not needing to change every component, when trying to achieve new functionality.

And while we're into "and", it passes notice, especially with this work, how this is only a straightforward approach because of the good old Mercator projection used here, that many primary school kids get familiar with regarding wall maps. A pixel is worth a Mercator projection degree, when "unzoomed", and that the top left corner is 90 degrees latitude and -180 longitude. The implication is that areas near the poles are vastly bigger looking than they are (regarding surface area) in reality. Many other projections would involve quite complex mathematics. Phewwww!

Today, further to yesterday's Region Picker GeoJson Trip Leg Tutorial, we worried a lot about the "zoom" button 🔍. We encourage users who use the "J" inhouse menu option with "Yes Trip Planning" to click the "zoom" button as many times as they need to before any Trip Legs are defined via right click actions (within shaded countries). You can involve multiple countries, too, where "marker" inhouse options are presented.

We also allowed for Trip Leg visibility toggling (after the event) via double click, on a leg, functionality in the changed latest draft Region Picker

Previous relevant Region Picker GeoJson Trip Leg Tutorial is shown below.

Nice legs! Regarding the trips, of course. Trip planning? GeoJson? Region Picker?

Yes, yesterday's Region Picker GeoJson Trip Planning Tutorial's progress had us starting to allow for a Trip Planner subset of functionality for our Google Image Chart Map Chart interfacing Region Picker. Our first job to do moving forward is to allow between ...

• Region Picker region representative geographical "marker" placements on the ...
• interfacing GeoJson world map ...
• be able to be right clicked to flag sets of two such right clicks defining endpoints for a Trip "Leg" drawn as a straight line with huge thanks to ...
