Proposal
Hi,
I m workin on a e-newspaper app with serverpod and I try to create an image thumbnail when user uploads a pdf, I want to get first page and create jpeg image from it. its possible to create with pdfrx page on client site but because it requires flutter ui, I cant use it server side. My question is if I can get Uint8List data of page in pdf. I share my example function for reference. regards.
Future<void> savePdfFirstPageAsImage(String pdfPath) async {
final pdfDocument = await PdfDocument.openFile(pdfPath);
final page = await pdfDocument.pages.first;
final pageImage = await page.render( // this requires ui
width: page.width,
height: page.height,
);
Uint8List pageData = pageImage!.bytes;
final image = img.decodePng(pageData);
final directory = await getApplicationDocumentsDirectory();
final imagePath = '${directory.path}/first_page.png';
final imageFile = File(imagePath);
await imageFile.writeAsBytes(img.encodePng(image!));
// Kaydedilen yol
print('Image saved at: $imagePath');
}
