Everytime I try to run 1 of the following options:

imageObject = PDImageXObject.createFromByteArray(document, image, 'TIF');
or
imageObject = LosslessFactory(document, image);

it gives me the error: No method 'org.apache.pdfbox.pdmodel.graphics.image.PDImageXObject.createFromByteArray'

with matching signature found.

And if I try

PDImageXObject.createFromFile(inputImage,document);

it gives me the error: java.io.IOException: First image in tiff is not CCITT T4 or T6.

The problem with this alternative is that I want the pdf colored, so inputImage has to be colored.

function ConvertToPDF(inputImage)%Image '.tif' or '.tiff'
import org.apache.pdfbox.pdmodel.*;
import org.apache.pdfbox.pdmodel.graphics.image.*;
import java.io.*
import javax.imageio.ImageIO.*
image = imread(inputImage);
numPages=length(imfinfo(inputImage));
document = PDDocument();
        
for page = 1:numPages
    image = image(:, :, :, page); 
    imageObject = PDImageXObject.createFromByteArray(document, image, 'TIF');%Error here
    pdfPage = PDPage();
    
    imageSize = size(image);
    pdfPage.setMediaBox(PDRectangle(imageSize(2), imageSize(1)));
    contentStream = PDPageContentStream(document, pdfPage);
    contentStream.drawImage(imageObject, 0, 0, imageSize(2), imageSize(1));
    contentStream.close();
    document.addPage(pdfPage);
end
%Save
outputFile = 'output.pdf';
document.save(outputFile);
document.close();
end

Hi Pablo,

I understand that you are facing issue in converting the TIF files into PDF files.

You can consider using the "print" function. For reference, please follow the sample code attached below:

ConvertToPDF('myfile.tif') 
function ConvertToPDF(inputImage)%Image '.tif' or '.tiff' 
image = imread(inputImage); 
fig = figure; 
imshow(image) 
print(fig,'MySavedPlot','-dpdf'); 
%Save 
end
