pdf render error
I used the demo and just replaced the Pdf file. There was a problem with the picture displayed after running.
// Load in an already created PDF
PDDocument document = PDDocument.load(assetManager.open("large.pdf"));
// Create a renderer for the document
PDFRenderer renderer = new PDFRenderer(document);
renderer.setDefaultDestination(RenderDestination.VIEW);
// Render the image to an RGB Bitmap
pageImage = renderer.renderImage(0, 1, ImageType.RGB);
I got the same issue, while opening a pdf with password. I didn't get that with a pdf without password.
`val inputStream: InputStream = FileInputStream(file)
// Load in an already created PDF
val document: PDDocument = PDDocument.load(inputStream, "azerty")
// Create a renderer for the document
val renderer = PDFRenderer(document)
// Render the image to an RGB Bitmap
val pageImage = renderer.renderImage(0, 1F, ImageType.RGB)
Handler(Looper.getMainLooper()).post {
if(pageImage != null){
binding.pwdPDFView.setImageBitmap(pageImage)
} else{
Toast.makeText(requireContext(), "Error BITMAP happened", Toast.LENGTH_SHORT).show()
}
}
// Your code to password protect the document will go here
document.close()`
Here the document : Password : azerty

No pdf found
Didn't work from Gmail here the pdf. single_password.pdf
I'm getting a normal rendering here.
`try { // Load in an already created PDF // PDDocument document = PDDocument.load(new File(path),"hi");
PDDocument document = PDDocument.load(assetManager.open("single_password.pdf"), "azerty");
// Create a renderer for the document
PDFRenderer renderer = new PDFRenderer(document);
// Render the image to an RGB Bitmap
pageImage = renderer.renderImage(0, 1, ImageType.RGB);
// Save the render result to an image
String path2 = root.getAbsolutePath() + "/decrypt_render.jpg";
File renderFile = new File(path2);
FileOutputStream fileOut = new FileOutputStream(renderFile);
pageImage.compress(Bitmap.CompressFormat.JPEG, 100, fileOut);
fileOut.close();
tv.setText("Successfully rendered image to " + path2);
// Optional: display the render result on screen
displayRenderedImage();
} catch (IOException e) {
Log.e("PdfBox-Android-Sample", "Exception thrown while rendering file", e);
}`
use :
implementation "com.tom-roush:pdfbox-android:2.0.27.0" , render error
use:
implementation project(':library') (source code) , render fine
What is that?
implementation project(':library') (source code) , render fine
It doesn't seem to be correct. If it's in gradle it leads to an error :
Project with path ':library' could not be found in project ':app'.
It will be a good idea to put the code directly in Kotlin and also directly in the readme.
I tried with a FILE and an InputStream but it was rendered like I previously showed. Not with all the letters of the text.
About your assetManager, how to initialise it ? In the sample I see a getAssets(), but I didn't find the function in the sample.
val assetManager: AssetManager = getAssets()
This gives an unresolved reference.
I'm getting the PDF from a DocumentPicker, so I can get the path with file.path. Not sure if that is gonna work with all the versions of Android.
For library, I just found where to add, but why do I need to add the library that way?
implementation "com.tom-roush:pdfbox-android:2.0.27.0"
This should contain everything needed, normally.
Is there a particular reason why, we have to do add the folder library manually?

implementation "com.tom-roush:pdfbox-android:2.0.27.0"实现“com.tom-roush：pdfbox-android：2.0.27.0”
This should contain everything needed, normally.通常，这应该包含所需的一切。
Is there a particular reason why, we have to do add the folder library manually?有没有特别的原因，我们必须手动添加文件夹库？
I understand that "com.tom-roush:pdfbox-android:2.0.27.0" is buggy, you can build a new aar based on the master branch of "PDFBox-Android".
Thank you. I'll be looking for another library. Seems too risky for production app.
