Version 3 changelog

Bug fix when exporting arcs drawn with compass tool to PDF

Fix for one PDF rendering issue ([CK] - empty text-based clipping path), and suppressed a couple of warnings where testing has shown Splash is rendering it correctly.

Splash remembers which page of a document a student was viewing and returns to same page if it is opened again soon afterwards.  Does not apply in teacher mode, and the current page is forgotten once about 10 other documents have been opened by the student.

Numbers tool will still follow page grid if X and Y sizes of grid differ (ie grid "squares" are actually rectangles).  Useful for some PDFs containing grids/tables which aren't actually quite square

Improvements to adding grid when importing a PDF:

- Addition of a manual placement tool.  The auto grid button has been moved with this into the grid palette, tidying all the grid functions into one place.

- The grid can optionally be rendered over the top of the PDF content during import, for PDFs containing large blocks of colour which would otherwise make it impossible to see clearly where Splash has placed the grid.

- PDF automatic grid will cope with pages with errors in the PDF (rendering is done as best as possible, whereas previously the grid-guesser stopped on a PDF error).  Also some improvements to the logic of the auto grid.  [AJ/4]

Improvement to using snap-to-shape with some "dots" in PDF pages which aren't actually dots within the PDF, but instead very small complex shapes. [CE]

Added the blank axis and axis label in KS3+ graph drawing - they were omitted at this level in previous update

Some improvement to how the geodriehoek is placed, and small improvements to the rendering when using large text

Bug fix: recent file menu was not showing in the menu in the student's menu page (worked OK in the work screen)

Removed the Low Graphics setting (was already only visible in Advanced mode settings)

Fix for some complex shaders in PDF import (single path shades or nested layers of non-standard composition), and many custom shaders now render much faster

Fix for some jpeg images using CMYK colours in imported PDFs which previously didn't render sometimes

Experimental: option to have numbers automatically displayed below the number arc line.  Also option to set whether first arc starts at beginning (as currently) or where the user selected.

Addition of blank axis tool and axis label tool which much more easily allow users to draw graphs with their own numbers/text along the axes

Addition of Number blocks activity

When a page has answer boxes, and the Numbers tool is used, Tab will now tab around the answer boxes (as it does in the text tool); previously it behaved the same in Numbers with or without answer boxes.

When a concave shape is selected and has grab handles which overlap (eg it has a vertex at the centre where the move is), mouse click better selects the more useful handle.

Added support for displaying original PDF page numbers using roman numerals (in the page selection screen during import) if the document is so configured

2 PDF bug fixes for Type 1 fonts with duplicated encodings, and old default fonts rendering invisible text.

But fix for importing PDF containing certain older font on non-English machines.

Tallies show a grab spot allowing them to be moved

Addition of versioning to translation files.

New geodreieck graphics improved with larger text sizes.  It is always placed 'above' initially and flipped using +- keys or button equivalent.  It can be placed horizontally at default size by selecting again after placing the centre point, without moving much.

Exam mode (and imported PDFs) no longer prevent student mode from adding pages

Bug fix for when the user locks the compass radius by reselecting it but without drawing anything - previously took wrong radius if nothing was drawn.

Significant changes to Geodreieck with custom graphics - now renders and behaves similarly to the other measures.  Currently configurable between old and new versions.

Fix for temporarily incorrect display when undoing the move of a simple text item.

In the Marker tool the solid circle display option now displays much smaller.

Modified ruler to display slightly longer ticks every 5th not every 2nd mm when displayed at full size.

Bug fix for possible error when cancelling the save-into-user-menu screen.

Bug fix for possible error with degenerate answer boxes in PDF import preview.

Minor change to use of F5-F8 in Grabspot only jump target mode.

Minor change for PDF import to suppress one error if files contain lines too short for Windows graphics (< 0.01px), and suppress a couple of warnings regarding items missing from the PDF; the documents render correctly in practice just ignoring these issues.

Added Geodreieck/Compass triangle tool.  (Not typically used in English-speaking countries).  Defaults to hidden and needs to be turned on in settings if required.

Some improvements to snap-to-shape with degenerate shapes (such as zero-width rectangles, or bullet points represented as small circles) to treat them more naturally as simpler objects - single lines or points rather than to try and trace around the outline.  Intended for content imported from PDF where the physical representation differs from the logical meaning of the content.

Bug fix for importing PDFs with a scale adjustment, in non-English systems.

Added "limit" and "function intervals" as new elements in equations:

Modification to file versioning: when incompatible changes are added to Splash, files saved will only require the new version of Splash if the new feature was used in the file.

Some improvements to creating answer boxes during PDF import, including:

• Splash filters out some spurious super-imposed content in the original PDF
• Splash will make the boxes flow in normal left-to-right, top-to-bottom reading order, regardless of the flow order in the original PDF (which is occasionally erratic)
• If an answer box is clicked with the simple text (ABC) tool, it will now type into the existing box rather than create a new typing shape over the top

Fix for error in reset user link in settings screen

Fix for loading PDF encrypted vs edit with a long key length (exceeding the hash length)

Blocked the add (blank) page functions during PDF import;  added the duplicate page function to the toolbar

Fix for error at end of Print Preview

Possible fix for unreproducible error in page preview thumbnails

Fix for rare issue if Splash running under a Windows temporary or mandatory profile causing licence to not appear valid (will require network connection in this case)

Fix for rare error when user draws a pie slice with zero angle then cancels it.

Improvement to display of overlaid hints when Splash runs for the first time.

Splash now blocks attempt to Undo the completion of importing a PDF document.

Fixes for a couple of PDF rendering issues [cases BU, BV]

Bug fix for packages sometimes showing as not available with Primary licences

Made the selection box tool (B) available during the PDF import preview.

Fix for flashing typing cursor sometimes not showing until a key is pressed when typing with the basic text tool.

Added page numbers to the page thumbnails on right hand side (not shown if there is only 1 page)

PDF import now omits printers marks around edges of pages which are not intended to be visible.

Bug fix for adding a PDF directly to the page within the menu page.

Bug fix for downloading the Inclusive image library which was failing due to changes on the server.

Improvement to efficiency of page thumbnails in documents (especially PDF) with a large number of pages of varying size.

Bug fix for equations containing immediately nested complex elements.

Bug fix for possible error on missing prompt (at bottom of screen)

Minor improvement to cursor navigation in equations: previously there were a few rare places where the cursor didn't navigate to (eg a divisor directly inside an empty square root - the cursor couldn't be placed to add text directly before but outside the divisor)

Added button which adds lines above and below to the popup palette for Numbers tool for KS2+ (already exists in Numbers palette, but is easier to use in pop-up palette if using Compact mode layout)

Changed Numbers main palette to use version which includes degree symbol for KS2+ users.

Added support for only-when-needed for show tables palette setting.

Added back the custom icon for Splash files (will only show if the Splash downloadable installer is run for v3.7.0 or later;  this change cannot be made by the auto-update)

Experimental: Added number block tool;  not currently displayed to user, but can be added through settings.

Added support for Splash to detect and reload settings changes if multiple copies of Splash share the same storage (relevant to modified installations only)

Added support for external software sending virtual keys, such as Clavier+.  Currently only if enabled in settings.

Fix for PDFs containing fonts containing Unicode Variance Tables.

Added option to show centre of arc and angular label as a point (if off, they can also use the existing option to show centre of all shapes)

Added a solid circle as an option for arrowheads on lines.

Added a solid circle as a style option in the Marker tool.

Bug fix when loading PDF documents on machines running Windows in a European language

Added "apply to all pages" option when editing page grid

Bug fix to rendering of some dotted page grids

Bug fix for selection of circle as part of grouped shape when advanced graphics editing enabled.

Improvement to handling of invalid/corrupted PDF documents - Splash will continue to render if most of page can be processed rather than stopping.

Minor improvements to screen layout with excessive number of tools displayed on left.

Installer now sets up file association (had been removed during v3 prototypes)

Bug fix for rare issue when inserting an equation-fraction from the Numbers tool and then starting and abandoning more complex content within that fraction.

Some improvements to axes with a very large number of ticks

Bug fix with applying current arrow-head selection when drawing out a new shape

Bug fix for narrow, dashed lines when saving as PDF

Improvement when docking a palette back on right which was resized a lot when detached

Updated with new Extended Validation signing certificate so installer and app should be accepted by WIndows Defender and SmartScreen and all firewalls as safe software.

Updates to staff tools

Removed upgrade reminder for non-public releases

First full release of v3
