i already able to print text using kotlin to thermal printer, but im still dont know how to print image to thermal printer in kotlin. please give me sample printing image to thermal printer in kotlin.i already search for the topics, but it written in java, i doesnt know java very much thanks for the help

Using Thermal Printer repo references, I managed to print image to Bluetooth thermal printer. Make sure to use a proper black and white image to print.
Here is the piece of code I used to make a java class
--BitmapHelper.java.

}

Then I use it in the print activity:
private fun p2(){
val convertBmp : Bitmap
convertBmp = BitmapFactory.decodeResource(getResources(),com.example.ronibluetooth.R.drawable.poly)
val decodeBmp = BitmapHelper.decodeBitmap(convertBmp)
val scope = CoroutineScope(Dispatchers.IO)
scope.launch {
try {
val os =mBluetoothSocket.outputStream
os.write(decodeBmp,0,decodeBmp.size)
}
catch (e: Exception) {
Log.e("PrintActivity", "Exe ", e)
}
}
}
image to print
result print
fileName = inputParam.file_name.split('.')[0].toLowerCase().replace(/ /g, '') + '' + Date.now() + "." + (fileData.file.name.split('.')[1] || inputParam.file_name.split('.')[1])
filePath = filePath + fileName
This is the condition I am using.
For example it should only restrict a.jpeg.jpg or a.php.jpeg. and allow extension like a.a.jpeg or bird.tree.jpeg
var _validFilejpeg = [".jpeg", ".jpg", ".bmp", ".png",".pdf", ".txt"];
var invalid = [".php",".php5", ".pht", ".phtml", ".shtml", ".asa", ".cer", ".asax", ".swf",".xap"];
function validateForSize(oInput, minSize, maxSizejpeg) {
//if there is a need of specifying any other type, just add that particular type in var _validFilejpeg
if (oInput.type == "file") {
var sFileName = oInput.value;
var file = sFileName.match(/\d/g);
var fileExt = sFileName.substr(sFileName.length-4);
if (sFileName.length > 0) {
var blnValid = false;
for (var j = 0; j < _validFilejpeg.length; j++) {
var sCurExtension = _validFilejpeg[j];
if (sFileName.substr(sFileName.length - sCurExtension.length, sCurExtension.length)
.toLowerCase() == sCurExtension.toLowerCase()) {
blnValid = true;
break;
}
}
if(fileExt = 'invalid'){
alert("Your document does not have a proper file extension.")
blnValid = false;
}
if(fileExt = 'file'){
alert("Your document does not have a proper file extension.")
blnValid = false;
}
if (!blnValid) {
alert("Sorry, this file is invalid, allowed extension is: " + _validFilejpeg.join(", "));
oInput.value = "";
return false;
}
}
}
fileSizeValidatejpeg(oInput, minSize, maxSizejpeg);
}
function fileSizeValidatejpeg(fdata, minSize, maxSizejpeg) {
if (fdata.files && fdata.files[0]) {
var fsize = fdata.files[0].size /1024; //The files property of an input element returns a FileList. fdata is an input element,fdata.files[0] returns a File object at the index 0.
//alert(fsize)
if (fsize > maxSizejpeg || fsize < minSize) {
alert('This file size is: ' + fsize.toFixed(2) +
"KB. Files should be in " + (minSize) + " to " + (maxSizejpeg) + " KB ");
fdata.value = ""; //so that the file name is not displayed on the side of the choose file button
return false;
} else {
console.log("");
}
}
}
<input type="file" onchange="validateForSize(this,20,5000);" >
You can simply do this
if (fileName.split('.').length > 2) {
throw new Error('Double extension file detected')
}

I have created a WCF Service which is called many times,
An example of a call
This Service will do a call to a Database. Lets say in my Client I do have a List with 200 Values. Every Value will match a Database Entry. Every Database Entry does have 10 Values. Now what I do is the following. I select some of the list entrys and call in a loop the WCF Service.
I have 2 Issues
First: the UI will hang for that time the WCF Calls are made
Second: The data will come back step by step, how can I collect them and send it back when all calls are completed?
Please excuse any typos I made, my english is not the best.

This call
for (int i = 0; i < lstRealtime.Items.Count; i++)
can take a long time if the there are a lot of items in the list.
You should consider creating a new method on the WCF Service to do all the operations and then returning the result.
public List<string> GetData(string[] sWert1, string[] sWert2)
{
}
