pdf render error

[hucong730]

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);

@hucong730 Do you have the original pdf file?

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()`

@MikaReesu I can try to solve it, can you provide the PDF file?

No pdf found

Didn't work from Gmail here the pdf.

Didn't work from Gmail here the pdf. single_password.pdf

I'm getting a normal rendering here.

use :
implementation "com.tom-roush:pdfbox-android:2.0.27.0" , render error
use:
implementation project(':library') (source code) , render fine

[MikaReesu]

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.

[MikaReesu]

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".

[MikaReesu]

Thank you. I'll be looking for another library. Seems too risky for production app.
