About this app

You want to create a WinDev Mobile application that allows you to:

Read a PDF (built-in or external PDF reader).

Edit a PDF (annotations, form filling, adding signatures, etc.).

👉 In WinDev Mobile 25, there is no native "PDF editor" control. You must use:

🔹 PDF Reading

Use the PDF Viewer control (available in WinDev Mobile since WM24).

Allows you to display a PDF stored locally or downloaded.

Example code:

PDF_Open("MyFile.pdf", PDFField)

Or use the Android/iOS API to open the PDF with an external application.

ShellExecute("MyFile.pdf")

🔹 PDF Editing/Annotation

WinDev Mobile does not directly integrate advanced editing. There are two solutions:

Third-party library (Android/iOS SDK)

Example: PDFTron
, Foxit PDF SDK
, PSPDFKit
.

Integrable via JNI (Android) or ObjC (iOS) with WinDev Mobile.

Convert the PDF to images, then use an Image field with a drawing to annotate, then re-export to PDF.

Conversion possible via third-party libraries (GhostScript, MuPDF).

Add a drawing/signature layer on top.

🔹 Simple PDF Signature

If you only need to fill out a form or sign, it's simpler:

Load the PDF into a viewer.

Capture a signature via a Drawing field.

Then merge the image with the PDF using a library (e.g., iText for Java/Android).

⚡ Guiding question:
Do you want a simple PDF reader in your app, or a full-featured editor (annotation, editing, signing)?
