Hi Lukas,
As I can understand, you want a pdf with each page as a given image in the folder. Instead of using the "hgexport" function, you can use the "exportgraphics" function to get the pdf. Given below is an example for the same:
% Specify the number of images
numImages = 10;
% Initialize a cell array to store the image file names
imageFiles = cell(numImages, 1);
for i = 1:numImages
imageFiles{i} = sprintf('image_%d.jpg', i); % Adjust the file extension if needed
end
% Create a new PDF
outputPDF = 'output.pdf';
% Create a figure for displaying images
hFig = figure('Visible', 'off');
% Loop over each image and add it to the PDF
for i = 1:numImages
% Read the image
img = imread(imageFiles{i});
% Display the image
imshow(img, 'Border', 'tight');
% Adjust the figure size to fit the image
truesize(hFig);
% Save the current figure as a PDF page
if i == 1
% Use 'append' option to create a new PDF
exportgraphics(hFig, outputPDF, 'Append', false, 'ContentType', 'vector');
else
% Append to the existing PDF
exportgraphics(hFig, outputPDF, 'Append', true, 'ContentType', 'vector');
end
end
% Close the figure
close(hFig);
Kindly refer to the following documentation for the "exportgraphics" function: https://www.mathworks.com/help/matlab/ref/exportgraphics.html
