oleibman 9bef9c90ce Tests Involving Decimal and Currency Separators
This was suggested by the investigation of issue #3811. No fix is necessary for the issue. However, two possible code solutions (Php setlocale, which comes with certain design flaws, and StringHelper set(Decimal/Thousands)Separator were suggested, and neither is adequately tested. This PR adds such tests.

Unusually, getting StringHelper Decimal Separator, Thousands Separator, and Currency Code can result in a change to those properties. So, the existing design in several tests where those properties are captured in Setup and restored in Teardown do not work quite as designed. Instead, the ability to set those properties to their default value (null) is added, and the tests re-done to restore the default in Teardown.

The two methods yield the same results when parsing input. However, they diverge when examining output fields through `getFormattedValue`. Such output is currently correct (usually) when using setlocale, but not when using StringHelper. The former works through the 'trick' of using `sprintf(%f)`, which generates a locale-aware string. However, using non-locale-aware `sprintf(%F)` followed by `str_replace` will produce the correct result for both setlocale and StringHelper. One place in the code uses a cast to string, which is incorrect for both methods. Following that up with the same str_replace makes it correct for both. These changes permit, but do not require, the user to avoid setlocale altogether.

It remains an open question whether Settings/Calculation::setLocale should set DecimalSeparator, CurrencySeparator, and CurrencyCode. That makes logical sense, but it would be a breaking change, and having to explicitly set those values when using setLocale does not seem especially burdensome. For now, such a change will not be made.

oleibman 9fcfa4b7ec Xlsx Support Flipping of Image (#3801)
* Xlsx Support Flipping of Image

Fix #731. Opened over 5 years ago, probably the second oldest problem I've worked on. Images attached to an Xlsx spreadsheet can be rotated, which is supported by PhpSpreadsheet. They can also be flipped along their horizontal and/or vertical axes, and that has not been supported. This PR adds that support.

oleibman 009e009811 Chart Dynamic Title and Special Font Properties (#3800)
* Chart Dynamic Title and Special Font Properties

Fix #3797. Excel allows a Chart Title to be a formula, albeit a very rigidly limited one. It can only be a reference to a single cell, and the worksheet name must be specified, and the column and row must be absolute. Methods are added to Chart/Title to accommodate this (and styling for it). This will be handled for input/output for Xlsx, and for output for Html.

The sample file which was submitted with this issue demonstrated that something else was missing. When setting the font for a chart title in Excel, you can specify all-caps or small-caps, options not available for most cell formatting. These are now added.

The sample file also fell into the category of spreadsheets which lose one or more charts when converted to Html. I have redone the "extend rows and charts" logic in Html Writer. It is now clearer (I hope) and more efficient, and hopefully this problem will not arise again.

* Sheet Background Images

Fix #1649, a 3-year-old issue long marked "stale". Excel supports background images on sheets; now PhpSpreadsheet will as well. Support is limited to Xlsx (read and write) and Html (write only). As far as I can tell, Excel Xml and Gnumeric do not support this, nor, of course, do Csv and Slk; Excel Xls does, but, as usual, how to handle it in BIFF format is a mystery; LibreOffice ODS supports it differently than Excel, and this is just another of many ODS style properties not currently supported by PhpSpreadsheet.

oleibman 656a7164e1 Address Some Chart Problems (#3771)
* Address Some Chart Problems

Fix #3767. The basic problem in that issue was user error, but it exposed a couple of problems in code which are being addressed.

When a spreadsheet with charts is loaded without the includeCharts option and then saved, a corrupt spreadsheet is created. I believe this has been the case for quite some time. Nothing in the test suite covers this scenario. It is, in fact, a difficult thing to test, since the problem is exposed only when the file is opened through Excel. The specific problem is that a rels file generated by the output writer continues to refer to the drawing file which described the chart, but that file is not included (and not needed) in the output spreadsheet. The resolution is kludgey. The information that the file will not be needed is not available when the rels file is written. But, when it comes time to write the drawing file, it is known whether the rels file included it. So, if nothing else has caused the file to be generated, it is written out as a basically empty xml file after all. This solves the problem, but I will continue to search for a less kludgey solution. This solution is, at least, testable; if a different solution is applied later on, the test being introduced here is likely to break so a new one will be needed.

When the provided spreadsheet is loaded with the includeCharts option and then saved, an error is exposed in processing the Chart Title caption when it doesn't exist. The change to Writer/Xlsx/Chart is simple and clearly justifiable. What is peculiar is that the error does not arise with release 1.29, but does arise with master. It is not at all clear to me what has changed since the release to expose the error - the code in question certainly hasn't changed. It is difficult to isolate changes because of the extensive number of changes following on the elimination of Php7.4 as a supported platform.

The provided spreadsheet is unusual in at least two senses. When opened in Excel, it will show a clearly default value for the chart title, namely 'Chart Title'. I cannot find anything in the xml corresponding to that text. Since I have no idea why Excel is using that title, I will not try to duplicate its behavior, so that loading and saving the provided spreadsheet will omit the chart title. I will continue to investigate.

The other sense in which it is unusual is that it includes some style files in the same directory as the chart. I doubt that PhpSpreadsheet looks at these. The styling after load and save seems to mostly match the original, although there is at least one color in the graph which does not match. I imagine it would be pretty complicated to formally support these files.

oleibman 64a1d1ab02 Slk Shared Formulas (#3776)
* Slk Shared Formulas

Fix #2267. The Slk format has a way to express a "shared formula", but the Slk reader does not yet understand it. Thanks to @SheetJSDev for documenting the problem and pointing the way towards a solution. It has taken a long time to get there. Part of the problem is that I have not been successful in getting Excel to use this type of construction when saving a Slk file. So I have resorted to saving a Slk file where shared formulas *could* be used, and then editing it by hand to actually use them. It would not surprise me in the least to have neglected one or more possible ways to specify a shared formula; but, at least the issue as documented is resolved, and if new issues arise, we'll probably be in better shape to deal with them.

* Theme File Missing But Referenced in Spreadsheet

Fix #3770. A rels file points to a non-existent theme file in the spreadsheet. In other similar cases (e.g. PR #3771), Excel opens such a spreadsheet, but with an error pop-up. Not so with this file; it just opens the spreadsheet without the pop-up. PhpSpreadsheet will now account for this unusual situation as well.

oleibman 1282f3d67c Performance Improvements for Csv Reader (#3769)
* Performance Improvements for Csv Reader

Investigating issue #381, a means was suggested to duplicated a problem, but no problem occurred ... except for performance. This involved a spreadsheet with a large number of cells, definitely not PhpSpreadsheet's strong point; even so, the program (entirely available in the issue) took a disastrous two or so hours to complete on my system. Looking at the Csv Reader code, several opportunities to cache results and avoid function calls jumped out, none of which seem to materially add to the maintenance burden of the program. Testing these changes resulted in a run time of about 20 minutes, still hardly a thing of beauty, but a huge improvement over the original and therefore worth proceeding with.

oleibman c5527ba534 Unexpected Namespacing in rels File (#3722)
* Unexpected Namespacing in rels File

Fix #3720. Third-party product created a spreadsheet which PhpSpreadsheet could not read because of unexpected namespacing in workbook.xml.rels.

The file which demonstrated the problem was attached to #3423, however I do not believe it was related to the original problem. Nevertheless, the original issue specifically called out Protection, so I put some Protection tests in the validation test for the fix. In doing so, I found that Style/Protection is particularly confusing. Its properties will often have the value `inherit`, which isn't all that helpful; and, even when the `locked` value is `protected`, the cell won't actually be locked unless the sheet is protected as well. The `hidden` property is even more obscure - it applies only to formulas, and refers to hiding the property on the formula bar, not in the cell. I have added methods `isLocked` and `isHiddenOnFormulaBar` to `Cell`. I corrected the docs to explain this. And, as long as I was looking at the docs, I corrected some examples to use `getHighestDataRow/Column` rather than `getHighestRow/Column`, a frequent problem for users (e.g. #3721).

As a side note, the change to Cell.php is my first use of the nullsafe operator. This is one of many new options available now that we require Php8.0+.

* Minor Simplifications

* Scrutinizer

It's being silly again. In many tests, we test a variable for non-null, then use that variable later and Scrutinizer knows it's not null. Not here. Oh well.

oleibman 52f5b24b6d Inconsistency Between Actual and Declared Type - Minor Break (#3715)
* Inconsistency Between Actual and Declared Type - Minor Break

Fix #3711. User set a cell value to float (implicitly by default value binder), then used `setDataType` to change its type to string. This caused a problem for Xlsx Writer, which uses the string cell values as an index into a Shared String array. However, as the cell actually contained a floating point value, Php treated it as an integer index; such a treatment is both deprecated, and leads to invalid values in the spreadsheet.

The use case for `setDataType` is not strong. The user always has the option to use `setValueExplicit` if the type is important. Setting a type afterwards, i.e. irrespective of the value, seems like a peculiar action. Indeed, there are no tests whatever for such use in the unit test suite.

There are two possible approaches to fixing this problem. The first is to add casts to the 3 or 4 places in Writer Xlsx which might be affected by this problem (hoping that you've found them all and realizing that similar changes might be needed for other Writers). The second is to change `setDataType` to call `setValueExplicit` using the current value of the cell, thereby possibly changing the cell value. I have gone with the second option - it seems like a much more logical approach, and guarantees that the content of the cell will always be consistent with its declared type. It is, however, a breaking change; if, for example, you have a cell with a string or numeric value and specify `boolean` to `setDataType`, the cell's value will change to `true` or `false` with no way to get back to the original.

oleibman 0d1c9e4e0e ListWorksheetInfo/Names for Html/Csv/Slk (#3709)
* ListWorksheetInfo/Names for Html/Csv/Slk

Fix #3706. ListWorksheetInfo is implemented for all Readers except Html. For most (not all), ListWorksheetInfo is more efficient than reading the spreadsheet. I can't think of a way to make that so for Html, but that shouldn't be a reason to leave it unimplemented.

ListWorksheetNames is not implemented for Html, Csv, or Slk. It isn't terribly useful for those formats, but that isn't a reason to omit it. The requester's use case consists of using IOFactory to create a reader for a file of unknown format and determining the first sheet name. That seems legitimate, but it is currently not possible without extra user code if the file is Html, Csv, or Slk; this PR will make it possible.

When Excel opens a Slk or Csv file, the sheet name is based on the file name. PhpSpreadsheet does this for Slk, but it uses a default name for Csv. I am not interested in creating a break for that behavior, but I have added a new boolean property `sheetNameIsFileName` with a setter to Csv Reader. The requester actually mentioned that possibility in our discussion, although it is not essential to the request.

As an adjunct to the issue, the requester wishes to use the worksheet name in `setLoadSheetsOnly`. That is already possible for Html, Csv, and Slk, but that particular property is ignored for those formats. I do not see a reason to change that behavior. This treatment is now explicitly noted in the documentation for property `loadSheetsOnly`.

There had been no tests for what happens when `loadSheetsOnly` is specified but no sheets match the criteria for the formats for which this makes sense (Xlsx, Xls, Ods, Gnumeric, Xml). The behavior was not consistent - some formats threw an Exception while others continued with a single empty worksheet. All cases attempt to set the active sheet, and they will now all throw identical Exceptions when they attempt to do so in this situation. Tests are added for each.

There also had been no tests for `loadSheetsOnly` returning more than one sheet. One is added.

* Avoid Allocating RowDimension Unneccesarily

This PR builds on PR #3527, introduced but subsequently closed by @goetas. The observation was that AutoFilter did not need to allocate a new RowDimension when the row was not to be filtered. While vetting the PR, it became apparent that Xlsx Writer also allocates RowDimension unnecessarily, with some minor adjustments possible for Ods and Mpdf as well. My tests confirm the initial observation that there can be a considerable memory savings when RowDimension is allocated only when needed. So, even though the original PR is withdrawn, there seems to be value in proceeding with it anyhow.

oleibman 6edc552013 Writer Xls Handle Characters Outside Unicode BMP
Fix #642. Opened over 5 years ago, probably the oldest problem I've worked on. And https://github.com/PHPOffice/PHPExcel/issues/1320, opened a year before that. And https://github.com/SpartnerNL/Laravel-Excel/issues/1521.

Shared/StringHelper::UTF8toBIFF8UnicodeLong calculates incorrect length for strings when they contain characters outside Unicode BMP. Xls uses UTF-16 to encode its strings, and characters outside BMP require a surrogate pair to encode. PhpSpreadsheet (and PhpExcel before it) have been counting these as a single character, but Excel counts them as 2. Change to compute the length as half the number of bytes in the UTF-16 string, as Excel does.

A formal test is added, but it's a bit difficult to follow. So I aso added a non-BMP emoji to 27template.xls, which will cause it to be both read by Xls reader and written by Xls writer. This would previously have created a corrupt worksheet. The emoji is now handled correctly.

oleibman c1968e57b2 Correct Re-computation of Relative Addresses in Defined Names (#3673)
* Correct Re-computation of Relative Addresses in Defined Names

Fix #3661. Insertion or deletion of rows or columns can cause changes to the ranges for Defined Names. In fact, only the absolute parts of such ranges should be adjusted, while the relative parts should be left alone. Otherwise, as the original issue documents, the adjustment to the relative portion winds up being double-counted when the Defined Name is referenced in a formula. The major part of this change is to ReferenceHelper and CellReferenceHelper to not adjust relative addresses for Defined Names. An additional small change is needed in the Calculation engine to `recursiveCalculationCell` when a Defined Formula is being calculated.

In a sense, this is a breaking change, but for an obscure use case which (a) was wrong, and (b) is unlikely to be of importance. Some of the tests in ReferenceHelperTest were wrong and are now corrected, with the results being cross-checked against Excel.

When a Defined Name using relative addressing is defined in Excel, the result is treated as relative to the active cell on the sheet in which the name is defined. PhpSpreadsheet treats it as relative to cell A1. I think that is a reasonable treatment, and will not change its behavior to match Excel's - that would definitely be a breaking change of some consequence.

An interesting use of relative address in a defined name is demonstrated at https://excelguru.ca/always-refer-to-the-cell-above/. Note that the steps there involve setting the selected cell to A2 before defining the name. When that spreadsheet is stored, the actual definition of the range is `A1048576`. Likewise, adding a defined name for the cell to the left would be stored as `XFD1`. This seems a little fragile, but Ods, which I believe does not have the same row and column limits as Excel, certainly treats these values the same as Excel. This particular construction is formally unit-tested. Note, however, that although using these Defined Names as a formula on their own works just fine, a construction like `=SUM(A1:CellAbove)`, as suggested in the article, seems to put PhpSpreadsheet calculation engine in a loop. In the likely event that I can't solve that before I merge this change, I will open a new issue to that effect when I do merge it. Note that this can be handled without defined names as `=SUM(A$1:INDIRECT(ADDRESS(ROW()-1,COLUMN())))`. PhpSpreadsheet will handle this as a cell formula, but not yet as a Named Formula.

The tests show a breakdown evaluating `=ProductTotal` (product of 2 formulas using defined names with relative addresses) on the sheet on which it is defined, but it works from a different sheet. The usual debugging techniques show me why this is happening, but I can't see how to overcome it. As above, if I can't solve it before I merge, I will open a new issue.

For those situations where I intend to open a new issue, tests are added but are marked Incomplete. Because of those, I will leave this PR in draft status for 2 weeks before moving forward with it.

* Fix productTotal Problem

Need to restore current cell after evaluating defined name.
