How to Convert HEIC file to PDF
We would like to convert HEIC file to PDF.
I tried with below code which works for JPG ( convert JPG to PDF) but not working for HEIC file , does lowagi has library to support HEIC files?
PublicAPI api = (PublicAPI) ThreadContainer.get().getPublicAPI();
//find primary page
//ClipboardPage mainPage = api.findPage("pyWorkPage");
String IMGstr = myStepPage.getString("pyFileSource");
String IMGname = myStepPage.getString("pyFileName");
IMGname = IMGname.substring(0, IMGname.lastIndexOf('.') == -1 ? IMGname.length() : IMGname.lastIndexOf('.'));
byte[] ImgArray = IMGstr.getBytes();
java.io.ByteArrayOutputStream outfile = new java.io.ByteArrayOutputStream();
com.lowagie.text.Document document = new com.lowagie.text.Document();
try {
com.lowagie.text.pdf.PdfWriter writer = com.lowagie.text.pdf.PdfWriter.getInstance(document, outfile);
writer.setStrictImageSequence(true);
document.open();
//Get array
com.lowagie.text.Image jpg = com.lowagie.text.Image.getInstance(Base64Util.decodeToByteArray(IMGstr));
//Scale the image
float scaler = ((document.getPageSize().getWidth() - document.leftMargin() - document.rightMargin()) / jpg.getWidth()) * 100;
jpg.scalePercent(scaler);

Hi @BRAHMESH@,
Are you using iText library for generating this document?
Here is the response i found from AI tool ,
iText is an open-source library for PDF manipulation, but it doesn't directly support HEIC reading. You need an additional library to convert HEIC to a supported format like JPG or PNG, then use iText to create the PDF.
Below is the sample code using ImageMagick :

import com.itextpdf.text.Document;
import com.itextpdf.text.Image;
import com.itextpdf.text.PageSize;
import com.itextpdf.text.pdf.PdfWriter;
public class HEICToPDFWithIText {
public static void main(String[] args) throws Exception {
String heicFilePath = "path/to/your/heic.heic"; // Replace with your HEIC file path
String tempImagePath = "path/to/temp.jpg"; // Replace with temporary image path
String pdfFilePath = "path/to/output.pdf"; // Replace with your desired PDF path
// Convert HEIC to JPG using ImageMagick (adjust command if needed)
Runtime.getRuntime().exec("magick convert " + heicFilePath + " " + tempImagePath);
// Create PDF document
Document document = new Document(PageSize.A4);
PdfWriter.getInstance(document, new FileOutputStream(pdfFilePath));
document.open();
// Read temporary image and add to PDF
Image image = Image.getInstance(tempImagePath);
document.add(image);
document.close();
// Clean up temporary image
new File(tempImagePath).delete();
System.out.println("HEIC converted to PDF with iText!");
}
}In the code you shared, would you be able to try using ImageMagicK to convert HEIC to JPG and try if it works ?
Here is the AI Query Link for your reference. You can modify and try to refine code further.
Hope this helps.

you mean Itext doesn't support conversion of HEIC files ?
i think the pega product is already shipped with itext-2.1.7 jar , In my code I don't see any issue with converting JPG/PNG to PDF ..the problem is ,it's not converting HEIC files.
I tried with Apache pdf methods "Org.apache.pdfbox.*" but getting an exception as java.util.NoSuchElementException at the line marked below ImageIO.getImageReadersByFormatName("HEIC").next(); .
Is it possible to convert HEIC to PDF without an importing any external libraries ?
PublicAPI api = (PublicAPI) ThreadContainer.get().getPublicAPI();
String IMGstr = AttachmentPage.getString("pyFileSource");
String IMGname = AttachmentPage.getString("pyFileName");
IMGname = IMGname.substring(0, IMGname.lastIndexOf('.') == -1 ? IMGname.length() : IMGname.lastIndexOf('.'));
try{
byte[] ImgArray = Base64Util.decodeToByteArray(IMGstr);
java.io.ByteArrayInputStream bais = new java.io.ByteArrayInputStream(ImgArray);
ImageReader reader = ImageIO.getImageReadersByFormatName("HEIC").next();
ImageInputStream iis = ImageIO.createImageInputStream(bais);

Hi @BRAHMESH@
Found this in iText website.
pdfRender: HEIC image encoding support.
Looks like the later versions of iText has the feature to handle HIEC.
Try this link, could be helpful to see if your HIEC is converted to PDF successfully.

@Sudha Sundeep D this link Image Converter - Online check not working for HEIC ..
pdfRender: HEIC image encoding support. PdfToImageRenderer library seems to be for converting PDF to HEIC ( rendering the output file in HEIC ) .. we are looking for converting HEIC to PDF.
