issue in add image to pdf in android

[shambhu-sharan]

image not showing in pdf .

[andob]

ok. can you give me example code and image?

[shambhu-sharan]

in gradle i have added

implementation 'com.github.librepdf:openpdf:1.3.25' implementation 'ro.andob.androidawt:androidawt:1.0.4'

file path-->file:///storage/emulated/0/pdf/company_logo_0.jpg

Bitmap bitmap = BitmapFactory.decodeFile(file.getPath()); ByteArrayOutputStream stream = new ByteArrayOutputStream(); bitmap.compress(Bitmap.CompressFormat.PNG, 100, stream); Image image = Image.getInstance(stream.toByteArray()); image.scaleAbsolute(100, 100); PdfPCell cellImg = new PdfPCell(image, true); PdfPTable imgTable = new PdfPTable(1); imgTable.addCell(cellImg);

I see that you are accesing the file path on non-scoped storage: file:///storage/emulated/0/company_logo_0.jpg non-scoped storage and write_external storage permissions are deprecated in latest Android versions and not a good practice. is that ok??

have you tried to access it from /storage/emulated/0/Android/your_package_name/files/company_logo_0.jpg or /data/data/your_package_name/files/pdf/company_logo_0.jpg

you can get those paths like this:

File dir = context.getExternalFilesDir(null);
File file = new File(dir, "company_logo_0.jpg");
///storage/emulated/0/Android/your_package_name/files/company_logo_0.jpg

or

File file = context.getFileStreamPath("company_logo_0.jpg");
///data/data/your_package_name/files/pdf/company_logo_0.jpg

I have targeted api v 29 (scoped storage come on 29+) and I have checked , I am getting file from storage, conversion to bitmap also ok . some png image display in pdf but most of image doesn't .

[andob]

ok, I'll take a look later today.

• loading that image as PNG doesn't seem to work
• also loading Image.getInstance(bytes) doesn't seem to work, but it works if you do Image.getInstance(filePath)

Try converting it into JPEG first:

        //convert to jpeg
        val bitmap=BitmapFactory.decodeFile(imageFile.absolutePath)
        FileOutputStream(imageFile).use { outputStream ->
            bitmap.compress(Bitmap.CompressFormat.JPEG, 100, outputStream)
        }

        val table=PdfPTable(1)
        val image=Image.getInstance(imageFile.absolutePath)
        image.scaleAbsolute(100.0f, 100.0f)
        val cell=PdfPCell(image, true)
        table.addCell(cell)
        pdf.add(table)
