Use `enum EImageFormat` type for image format literals and variables.
Add `PixelSize` function to get the number of bytes/color channels per pixel for a specified image format.
Remove unused store format argument of texture loading functions. All textures are automatically being stored as RGBA, so the argument was unused. Also remove the therefore unused `FORMAT_AUTO`.
Rename variables consistently to `PixelSize` and use `size_t`, instead of mixing different names like `BPP` and `ColorChannelCount`.
Validate image format loaded from maps using `CImageInfo::ImageFormatFromInt`. Add `FORMAT_ERROR` to represent invalid formats.
Remove redundant `PixelSize` parameter from graphics backends and commands, which can be derived from the texture format.
Fix memory leak when RGB image data is being converted to RGBA format when saving map in editor.
Simplify memory management of groups, layers, images, sounds and envelopes by using `std::shared_ptr` for all of them.
Clear brush when creating a new map to prevent crash due to unloaded textures being used in tile layer. Closes#6935.
Also fix crash when restoring a saved brush after removing an image that is being used by it.
Port map and editor support for `CURVETYPE_BEZIER` from upstream, i.e. support bezier curves with configurable in- and out-tangents for every envelope point.
The in- and out-tangents are represented by triangles and can be dragged in the envelope editor like the envelope points.
Support reading and writing the bezier information as a separate UUID-based map item. If the bezier information is not found, bezier will default to linear behavior. Old clients will still be able to read the new maps and ignore the unknown map item. The unknown curvetype will also be handled as linear by old clients.
Allow reading upstream maps that use `CMapItemEnvelope` version 3. On upstream, a different struct is used to store all envelope points including bezier information, which broke compatibility to old clients.
Fix holding Ctrl for slow envelope point editing not working for vertical movement.
Highlight the currently selected element (envelope point or bezier tangent marker) which is being used with the value/time edit boxes.
Hide the value/time edit boxes when no element is selected.
A copy of the map currently open in the editor is saved every 10 minutes to the `maps/auto` folder (interval configurable, see below). The automatically saved map uses the filename of the original map with an additional timestamp. Per map name 10 autosaves are kept in the `auto` folder before old autosaves will be deleted (number configurable, see below).
Add config variable `ed_autosave_interval` (0 - 240, default 10) to configure the interval in minutes at which a copy of the current editor map is automatically saved to the 'auto' folder.
Add config variable `ed_autosave_max` (0 - 1000, default 10) to configure the maximum number of autosaves that are kept per map name (0 = no limit).
Autosaving will not take place in the 5 seconds immediately after the map was last modified by the user, to avoid interrupting the user with the autosave.
This will only delay autosaving for up to 1 minute though, so autosaves are not prevented entirely, should the user continuously edit the map.
When the editor is reopened after being closed for more than 10 seconds, the autosave timer will be adjusted to compensate for the time that was not spent on editing in the editor.
When the map is saved manually by the user the autosave file is also updated, if it's outdated by at least half of the configured autosave interval. This ensures that autosaves are always available as a periodic backup of the map.
When a copy of the current map is saved, this does not update the autosave and will also no longer reset the modified state. The modified state should reflect whether changes have been made that are not saved to the current map file. As saving a copy does not update the current file, the modified state should not be reset in this case.
Closes#6693.
When using "Save Copy" to save a copy of the current map to a new file and selecting a file that already exists, a confirmation popup is shown. However, this confirmation popup did not differentiate between regular saving and saving a copy, so the regular save callback was always called.
By replacing the editor specific color picker popup with the generic UI color picker popup.
Improve layout of the editor color picker button. Improve spacing and ensure that the button is square. Slightly enlarge button on mouse hover.
Use templated `str_copy` function in most cases to specify the correct buffer size.
Fixes two cases where the buffer size was hard-coded to a number.
Fix buffer size not being checked when copying auto mapper configuration name. Loading an auto mapper configuration with a name longer than 128 bytes could cause an out-of-bounds write.
Increase sizes of some text buffers that were potentially too small.
- Support scrolling. Limit maximum height to 40% of screen height.
- Allow message to be empty.
- Use `std::vector` instead of `std::set` for entries to keep the user-defined order of entries.
- Add `m_SelectionIndex` in addition to `m_pSelection` to get selected item more conveniently for some use-cases.
- Make entry height, entry padding, entry spacing, font size, and popup width configurable.
- Allow alignment of selection popup with the top/bottom of another UI element.
- Support transparent selection buttons.
