Example usage

ColumnPdfViewer composable function provides a simple scrollable column PDF viewer, fillers and "more" menu can be customized using PdfViewerColors and options parameters. PDF document can be provided via URL, Uri or Raw resource using corresponding PdfProvider.

For example, following code (see more in MainActivity.kt) will result in something like this:

ColumnPdfViewer(
  modifier = Modifier.fillMaxSize(),
  pdfProvider = PdfProvider.ResProvider(
    resId = R.raw.sample_multipage,
    bitmapScale = 3,
    identifier = "sample_multipage"
  ),
  colors = PdfViewerColors(
    fillerPageColor = Color.Black,
    floatingElementsColor = Color.Blue,
    iconButtonColors = IconButtonDefaults.iconButtonColors(),
    textFieldColors = TextFieldDefaults.colors()
  ),
  options = listOf(
    PdfViewerOption(
      title = "SampleOption",
      action = {
        Toast.makeText(context, "Sample text", Toast.LENGTH_SHORT).show()
      }
    ),
    PdfViewerOption(
      title = "SampleOption2",
      action = {
        Toast.makeText(context, "Another sample text", Toast.LENGTH_SHORT).show()
      }
    )
  ),
  fillerAspectRatio = 1f / sqrt(2f)
