2019.2 Migration Guide | Web

PSPDFKit for Web 2019.2 comes with a few improvements that might require an ad hoc migration.

Notable Changes

  • We renamed all *.onPress events to *.press to improve consistency with our event naming schema. The old names are now deprecated and will be removed in a future version. The name changes are as follows:

    • annotations.onPress to annotations.press

    • textLine.onPress to textLine.press

    • page.onPress to page.press

  • Shape annotations had their stroke width scaled when resized with the UI. As a result, the different annotations’ stroke widths could vary if resized. This behavior has been changed, so now a shape annotations’ stroke width is kept when resizing.

  • The default minimum stamp annotation size, PSPDFKit.Options.MIN_STAMP_ANNOTATION_SIZE, has been increased from 10 to 15. The former value was so small that stamp annotations resized that small would have their text clipped in a way that the stamp text wouldn’t fit (#2977). If your code relies on the former value, you can set it before the first PSPDFKit.load() call: PSPDFKit.Options.MIN_STAMP_ANNOTATION_SIZE = 15.

  • In a recent version, we accidentally disabled an optimization that reduces the number of points an ink annotation creates while drawing. This release restores the previous behavior. You can opt out this behavior by setting PSPDFKit.Options.INK_EPSILON_RANGE_OPTIMIZATION = 0.

  • We renamed FormField#annotationPdfObjectIds to FormField#annotationIds.

  • When in continuous scroll mode, we now remove custom overlay items from the DOM if you scroll a certain number of pages below the page they items are rendered on. If you previously depended on custom overlay items being persisted in the DOM (e.g. wanted to maintain its state), you will now have to handle this explicitly with the CustomOverlayItem#onDisappear method.

    For example, if you’re using a <video> tag and want to maintain its current position, you could:

    • Query the current position in onDisappear and apply it again with onAppear, or

    • Move (appendChild) the <video> node to another place in the DOM (e.g. an invisible div outside the viewport) and append it back to the custom overlay item onAppear. This will keep most of the state around.

  • We moved the public CSS classes for shape annotations and ink annotations from their svg element to their container (parent).
