| **************************************************************************** |
| * Qt PDF * |
| **************************************************************************** |
| |
| General |
| ------- |
| |
| - The qt-labs/qtpdf module was using an out-of-date version of pdfium. |
| Development will now continue in the qtwebengine repository in order to |
| reuse Qt WebEngine's pdfium build system integration. |
| - QtPdf is still in Tech Preview. |
| - It's now possible to build QtPDF for iOS (even though Qt WebEngine does not). |
| - Added a Qt Quick API (import QtQuick.Pdf): |
| * Added an image plugin: Image { source: "my.pdf"; currentFrame: 2 } is |
| enough to view the third page in a PDF file. |
| * High-level API for full-featured viewers: PdfScrollablePageView shows |
| one page at a time; PdfMultiPageView allows flicking vertically from |
| page to page. These are implemented in QML and packaged with the module. |
| - Low-level QtQuick API: |
| * PdfDocument provides API for the document and its metadata. |
| * PdfSearchModel can find a text string and provides information about |
| the locations where it is found on each page, which can be listed in |
| a ListView and visualized by using a Repeater to instantiate |
| QtQuick.Shapes for the bounding boxes. |
| * PdfSelection allows selecting text and copying to the clipboard; |
| visualization of the selected region is done via QtQuick.Shapes. |
| * PdfLinkModel provides information about the links in the document; |
| visual feedback and clicking can be handled with QtQuick.Shapes |
| and TapHandler, respectively. |
| * PdfNavigationStack is a model for implementing forward/back navigation. |
