Error while trying to convert a TIF file to a PDF file

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 

Using the above attached sample code, you should be able to convert the TIF file into PDF.

For more details, you can refer to the "print" documentation using the following link.

I hope this helps.
