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

My application actually has mail send / receive functionalities to handle.
While receiving the mail, i am unable to view the image which is an inline image being sent from outlook.
Can some one help me how can i catch the image and make available always.
I have java code like below,
try (InputStream stream = new ByteArrayInputStream(Base64
.getMimeDecoder().decode(mail))) {
MimeMessage message = new MimeMessage(null, stream);
Object messageContent = message.getContent();
if (messageContent instanceof String) {
body = (String) messageContent;
} else if (messageContent instanceof MimeMultipart) {
content = (MimeMultipart) messageContent;
for (int i = 0; i < content.getCount(); i++) {
BodyPart bodyPart = content.getBodyPart(i);
String disposition = bodyPart.getDisposition();
if (disposition == null
|| disposition
.equalsIgnoreCase(Part.INLINE)) {
Object object = bodyPart.getContent();
if (object instanceof String) {
body = object.toString();
} else if (object instanceof MimeMultipart) {
MimeMultipart mimeMultipart = (MimeMultipart) object;
String plainBody = null;
String htmlBody = null;
for (int j = 0; j < mimeMultipart.getCount(); j++) {
BodyPart multipartBodyPart = mimeMultipart
.getBodyPart(j);
String multipartDisposition = multipartBodyPart
.getDisposition();
String multipartContentType = multipartBodyPart
.getContentType();
if (multipartDisposition == null
&& multipartContentType != null) {
if (multipartContentType
.contains(MediaType.TEXT_HTML)) {
htmlBody = multipartBodyPart
.getContent().toString();
} else if (multipartContentType
.contains(MediaType.TEXT_PLAIN)) {
plainBody = multipartBodyPart
.getContent().toString();
}
}
}
if (htmlBody != null) {
body = htmlBody;
} else {
body = plainBody;
}
}
}
}
}
Client side i am using CKEditor to handle email body data.
Thanks a lot.
i got a solution from the example shared below
https://www.tutorialspoint.com/javamail_api/javamail_api_fetching_emails.htm
But, this example explains, how to find the image in body and store.
I have also done below to replace src
`
Pattern htmltag = Pattern.compile("]src=\"[^>]>(.?)");
Pattern link = Pattern.compile("src=\"[^>]\">");
String s1 = "";
Matcher tagmatch = htmltag.matcher(s1);
List<String> links = new ArrayList<String>();
while (tagmatch.find()) {
Matcher matcher = link.matcher(tagmatch.group());
matcher.find();
String link1 = matcher.group().replaceFirst("src=\"", "")
.replaceFirst("\">", "")
.replaceFirst("\"[\\s]?target=\"[a-zA-Z_0-9]*", "");
links.add(link1);
s1 = s1.replaceAll(link1, "C:\\//Initiatives_KM\\//image.jpg");
}
`
And on top of this, i gonna do Base64 encoding so that i dont require store in file system.
encodedfileString = Base64.getEncoder().encodeToString(bArray);
With all these i can conclude to say, i got solution for my issue. Thank you.
I'm trying to get the following example working in a Xamarin.Mac project.
It's an AUGraph that connects a mixer to the default output. The mixer has one input which is a render callback that generates a sine wav.
var graph = new AUGraph();
var output = graph.AddNode(AudioComponentDescription.CreateOutput(AudioTypeOutput.Default));
var mixer = graph.AddNode(AudioComponentDescription.CreateMixer(AudioTypeMixer.MultiChannel));
if (graph.TryOpen() != 0)
{
throw new Exception();
}
var mixNode = graph.GetNodeInfo(mixer);
// configure mixer
if (mixNode.SetElementCount(AudioUnitScopeType.Input, 1) != AudioUnitStatus.OK)
{
throw new Exception();
}
if (mixNode.SetRenderCallback(HandleRenderDelegate, AudioUnitScopeType.Global, 0) != AudioUnitStatus.OK)
{
throw new Exception();
}
var outNode = graph.GetNodeInfo(output);
// define stream description
var desc = new AudioStreamBasicDescription();
desc.BitsPerChannel = 32;
desc.BytesPerFrame = 4;
desc.BytesPerPacket = 4;
desc.Format = AudioFormatType.LinearPCM;
desc.FormatFlags = AudioStreamBasicDescription.AudioFormatFlagsAudioUnitNativeFloat;
desc.FramesPerPacket = 1;
desc.ChannelsPerFrame = 2;
desc.SampleRate = 44100;
// set mixer input format
if (mixNode.SetFormat(desc, AudioUnitScopeType.Input, 0) != AudioUnitStatus.OK)
{
throw new Exception();
}
// connect mixer's output to the output
if (graph.ConnnectNodeInput(mixer, 0, output, 0) != AUGraphError.OK)
{
throw new Exception();
}
// set format of mixer's output
desc = mixNode.GetAudioFormat(AudioUnitScopeType.Output);
desc.SampleRate = 44100;
if (outNode.SetFormat(desc, AudioUnitScopeType.Input,0) != AudioUnitStatus.OK)
{
throw new Exception();
}
if (mixNode.SetFormat(desc, AudioUnitScopeType.Output) != AudioUnitStatus.OK)
{
throw new Exception();
}
if (graph.Initialize() != AUGraphError.OK)
{
throw new Exception();
}
if (graph.Start() != AUGraphError.OK)
{
throw new Exception();
}
The callback:
int sample = 0;
unsafe AudioUnitStatus HandleRenderDelegate(AudioUnitRenderActionFlags actionFlags, AudioTimeStamp timeStamp, uint busNumber, uint numberFrames, AudioBuffers data)
{
var left = (float*)data[0].Data;
var right = (float*)data[1].Data;
for (var i = 0; i < numberFrames; i++)
{
float sampleValue = (float)Math.Sin(sample * 2 * Math.PI * 440 / 44100);
left[i] = right[i] = sampleValue;
sample++;
}
return AudioUnitStatus.OK;
}
The callback is running and the buffer is being filled but no sound is generated. The example works in iOS with AudioTypeOutput.Remote being used in place of AudioTypeOutput.Default but for some reason macOS is not playing the sound. Any ideas?
The output volume of the mixer had to be set manually because it defaults to 0.
My J2ME midlet could retrieves message in Chinese character from a PHP server but it's garbled. The server basically returns the response string and by detecting the first 2 characters. AA = good, anything else indicates error of which the message is to be passed to the calling function for display

On the PHP server, I have set the header to UTF-8 encoding
<?php header("Content-Type:text/plain; charset=utf-8"); ?>
What could possibly be wrong?
I found that this user has the same problem and it's been answered
Reading UTF8 strings from a server through http using MIDP. Kudos to the answer.
I basically edited my MIDP code from
// is = http.openDataInputStream();
// int length = (int) http.getLength();
// if (length != -1)
// {
// // Read data in one chunk
// byte serverData[] = new byte[length];
// is.read(serverData);
// str = new String(serverData);
// }
// else // Length not available...
// {
// ByteArrayOutputStream bStrm = new ByteArrayOutputStream();
// int ch;
// while ((ch = is.read()) != -1)
// bStrm.write(ch);
//
// str = new String(bStrm.toByteArray());
// bStrm.close();
// }
to
Reader r = new InputStreamReader(http.openInputStream(), "UTF-8");
int ch;
while((ch = r.read()) != -1)
str = str + (char)ch;
just wondering though why does reading bytes messes up the UTF-8 characters?
I could get the handle to the google text doc i needed. I am now stuck at how to read the contents.
My code looks like:
GoogleOAuthParameters oauthParameters = new GoogleOAuthParameters();
oauthParameters.setOAuthConsumerKey(Constants.CONSUMER_KEY);
oauthParameters.setOAuthConsumerSecret(Constants.CONSUMER_SECRET);
oauthParameters.setOAuthToken(Constants.ACCESS_TOKEN);
oauthParameters.setOAuthTokenSecret(Constants.ACCESS_TOKEN_SECRET);
DocsService client = new DocsService("sakshum-YourAppName-v1");
client.setOAuthCredentials(oauthParameters, new OAuthHmacSha1Signer());
URL feedUrl = new URL("https://docs.google.com/feeds/default/private/full/");
DocumentQuery dquery = new DocumentQuery(feedUrl);
dquery.setTitleQuery("blood_donor_verification_template_dev");
dquery.setTitleExact(true);
dquery.setMaxResults(10);
DocumentListFeed resultFeed = client.getFeed(dquery, DocumentListFeed.class);
System.out.println("feed size:" + resultFeed.getEntries().size());
String emailBody = "";
for (DocumentListEntry entry : resultFeed.getEntries()) {
System.out.println(entry.getPlainTextContent());
emailBody = entry.getPlainTextContent();
}
Plz note that entry.getPlainTextContent() does not work and throws object not TextContent type exception
finally i solved it as:
for (DocumentListEntry entry : resultFeed.getEntries()) {
String docId = entry.getDocId();
String docType = entry.getType();
URL exportUrl =
new URL("https://docs.google.com/feeds/download/" + docType
+ "s/Export?docID=" + docId + "&exportFormat=html");
MediaContent mc = new MediaContent();
mc.setUri(exportUrl.toString());
MediaSource ms = client.getMedia(mc);
InputStream inStream = null;
try {
inStream = ms.getInputStream();
int c;
while ((c = inStream.read()) != -1) {
emailBody.append((char)c);
}
} finally {
if (inStream != null) {
inStream.close();
}
}
}
