B4J Question Overlapping images + text, on Google Maps markers

[amorosik]

I use jGoogleMaps to display a map and markers with the positions of some cars
For each car I have a small image that is used to display the car on the map
In addition to the position I would also like to indicate the direction of the individual cars and a text to indicate the speed and the name of the driver
So the marker should consist of: - small car image - arrow image to indicate direction - alphanumeric string to indicate speed and driver
I currently load the small car image using the function
gmap.AddMarker2 (lat, lon, "Targa =" & Targa_Auto, File.GetUri (File.DirAssets, graphic_marker))
And so I'm missing the arrow image to indicate direction, and the string image containing other information
How to "add" to the image of the car, a small arrow rotatable from 0 to 360 degrees, and then an alphanumeric string?

see anchor.

Google Maps Waypoint Anchor Change

Any marker added with the jGoogleMaps library displays the marker with the bitmap anchored at the centre of the bottom margin. Is it possible to expose the properties of the marker such that the bitmap is centred over the co-ordinate rather than above it? Rather like the Android library...

In my case, the infowindow was WAY too big to show relevant data (the speed) for each marker.
Everything overlapped and you could not see anything until you zoomed in.. It was just a mess...

usually.
if they are vehicles, a fixed label with the data of the car plate is displayed.
or
car plate and speed.

the other data is displayed in the information windows (infowindow).

 

[Harris]

a fixed label with the data

By this statement, you mean a bitmap (png) for the marker "label"....?

yes, as an example the attached image

Yes, this is the effect that i want to see
But also with direction of car

You must:

Create a label on canvas with car plate and speed.

The angle is the direction the car is pointing.

One image for every degree ?
360 little cars?
Naaaaaaa is a very non elegant method

We work with more than 3,000 vehicles.

Thank you very much for the help
But is the WriteOnImage.zip example related in any way to the above code?
I ask this because it seems to me quite another thing

Now, you may understand why I provided this... as a foundation to produce image markers.

I suppose one could also create bitmaps "on the fly" - affixing the required label text accordingly.
I have limited functionality with the ABMGoogleMap with regards to manipulating markers, so this works for me..

You're right.

The idea is to generate bitmap labels with the data you want dynamically.

Attached a demo. (tested on B4A and B4J)

The rest is up to your imagination.

Sample:

Estimated,

You may have an option for users if they want to view the vehicle data labels.

to avoid what was commented by @Harris .

Excellent for create an image from text, but how to place the image on a map (jGoogleMaps) and near or above a marker?

 

[Harris]

Use the AddMarker2 method. The IconURI will point to the directory and filename of the png....

How to convert text to transparent bitmap

I need some custom bitmaps to show the google map marker titles of all markers automatically without tapping. The created bitmap should just be large enough to show entire text. I'm facing two problems with following code: 1. B4XCanvas expects a view which I can't provide; the created bitmaps...
