2018-07-06Fix muraster and mu-office-lib.Robin Watts
These got broken during the fz_rect/fz_matrix pass-by-value changes.
2018-07-06Add pdf_dict_get_rect and pdf_dict_get_matrix helpers.Tor Andersson
2018-07-06gl: Add signing UI for Digital Signatures.Tor Andersson
All the "Sign" button does for now is recreate the appearance stream.
2018-07-06gl: Multi-line labels.Tor Andersson
2018-07-06Fix bad error handling in pdf_pkcs7_openssl_read_pfx.Paul Gardiner
Failure within this function could lead to segfaults in drop_signer. The problem was early allocation of the signer struct without setting its drop method, so that on error signer was non-null, but not in a state where drop_signer could be called.
2018-07-05Fix document signing adding unnecessary incremental updatesPaul Gardiner
When a document is signed multiple times, an incremental update is needed for each, the multiple updates sometimes written to the file as a single saving operation. Within pdf_sign_signature it is the call to pdf_signature_set_value that marks the current section of the xref to which changes are recorded as "full", so that subsequent changes will trigger the creation of a new section. Within pdf_sign_signature we were creating the signature's appearance stream after the call to pdf_signature_set_value and hence triggering an extra unnecessary setction. This commit moves the pdf_signature_set_value to after the creation of the appearance stream, so that we need only as many new xref sections as there are signings.
2018-07-05Signature support: add signing support to the windows appPaul Gardiner
2018-07-05Add digital signature appearance synthesis.Tor Andersson
The pdf_update_signature_appearance function must be called directly by the signing code when it signs the document; as only the signing code has all the text that needs to be written into the appearance.
2018-07-05Add fz_transform_page helper function.Tor Andersson
Create a matrix that transforms a page with resolution and rotation, and grid fits the resulting bounding box.
2018-07-05Purge unused functions.Tor Andersson
2018-07-05Silence warning.Tor Andersson
2018-07-05Pass rects by value: device and document interface.Tor Andersson
2018-07-05Pass matrices by value: device and document interface.Tor Andersson
2018-07-05Pass rect and matrix by value in geometry functions.Tor Andersson
Several things irk me about passing values as const pointers: * They can be NULL, which is not a valid value. * They require explicit temporary variables for storage. * They don't compose easily in a legible manner, requiring weird pointer passing semantics where the variable being assigned is hidden as an argument in the innermost function call. * We can't change the value through the pointer, requiring yet more local variables to hold copies of the input value. In the device interface where we pass a matrix to a function, we often find ourselves making a local copy of the matrix so we can concatenate other transforms to it. This copying is a lot of unnecessary busywork that I hope to eventually avoid by laying the groundwork with this commit. This is a rather large API change, so I apologize for the inconvenience, but I hope the end result and gain in legibility will be worth the pain.

2018-07-04Fix bugs in triggering has_new_ap update.Tor Andersson
* Trigger correctly on AS state changes. * Handle the case when there is no AP (such as for unchecked checkboxes): - Don't try to create Widget/Btn streams. - Don't flag/unflag when AP synthesis throws.
2018-07-04Don't forget to resolve indirect references when clearing dirty flag.Tor Andersson
2018-07-04Clean up some incomprehensible code.Tor Andersson
2018-07-04Add fz_snap_selection function to snap selection to chars/words/lines.Tor Andersson
Updates the input point coordinates, and also returns a quad with appropriate UI handles.
2018-07-04gl: Track modifier keys during mouse events too.Tor Andersson
2018-07-04Rename pdf_get_annot_contents to pdf_annot_contents.Tor Andersson
Since the function no longer returns ownership of the string, use the common naming convention.
2018-07-04java: Fix bugs introduced when caching text strings in pdf_obj.Tor Andersson
2018-07-04Add fz_is_point_inside_rect utility function.Tor Andersson
2018-07-04Allow for CIDToGIDMap in font being "/Identity".Robin Watts
Previously we would have tripped over this, thrown an error and aborted loading the whole page. Any non-stream, non "Identity" CIDToGIDMaps now produce a warning rather than an error so we don't stop processing the entire page.

The Dingbats and Symbol fonts have not been changed.
