Maintenance update to prevent some views and controls from not displaying clearly when device is set to dark mode.

Maintenance update.

New solid background colors available in the 'Size' pane. Be sure to select 'Include In Spectra' if desired, otherwise the selected background only applies to the editor view.

Multiple audio channel support added. Previously only the first audio channel was used. Previous Updates: Added HDR video support by converting HDR to SDR to improve colors; presents a reminder that you can set a background color for spectra videos from the Size view. 13 new presets have been added to the built-in settings library. Settings are available in the Presets tab. The Presets tab has two tables named Built-In and My Settings. These new presets appear in the Built-in settings, at the bottom. Your own settings are saved to My Settings. 126 new presets have been added to the built-in settings library. These were previously available from 'More Settings' and required individual downloads. This makes a large variety of presets readily available with ease. NEW - Shadow option in the 'Lines' pane. This option will draw shadows for every line. FIXED - After app relaunch the 'Play Waveform Audio' may sometimes play the wrong audio file. New - When saving a spectra as a video you now have the option of including the audio, if available. The video duration will then match the audio duration. This can create a fun visualization of the audio. New - Audio menu has new menu item named 'Share Waveform Audio' enabling you to send the waveform audio, if there is one, to an email, message, etc. Fixed - Issue with audio processing that could prevent a settings file that uses audio from being restored to the correct look. It was due to a slight variation in audio modulation values. This issue was caused by changes in the last version. • IMPROVED: Video color generation faster. • NEW: Apply audio or set background image from Settings. ‘Apply Audio’ for audio, 'Set Background' for background. • NEW: Playing audio shows its progress in the waveform graphic. • NEW: When switching to settings without a background from one that does an option to remove the current background is offered. • NEW: ‘Use Opened Audio’ menu item in the Audio menu: sets the current audio to the last audio imported from external apps (Files, iCloud, Messages, Music, etc) or internal samples. • IMPROVED: The audio menu items 'Use Video Audio' and 'Use Settings Audio' are reimplemented for clarity. • FIXED: Some audio files were not loading due to a mismatch of file extension and audio type. • NEW: Option apply current background color to spectra when rendering. The background color is set in the Size pane. • Other improvements. Updated 'More Settings' web view. Use 'More Settings' to load additional settings from the web into the 'My Settings' table. Fixed an issue with the 'My Settings' table where the table experienced inadvertent scrolling after selecting a setting. Updated for iOS 14. FIXED: Saving background images to the Photos library now preserves transparency. In this way restoring a background from the photos library will restore the transparency, which is important for the mask mode of the Color pane. Improved Performance: Settings data is cached to handle the increased load from incorporating background images and waveform audio files. Most notably the presets table scrolls more smoothly, but other methods that use settings data is faster. Background Preview in Settings: The background image can be previewed from the user settings table. (Swipe on a row in iOS, right(control)-click on a row in macOS.) Open Settings Options: Opening settings is more discriminate - if current settings has background, but new settings do not then an alert is presented because the existence of a background could mean the spectra does not look as expected unless you change the background settings. Play Waveform Audio: The current waveform audio file can be played (if it exists; a waveform graphic only displays the audio samples, and its presence does not mean there is an audio file associated with it.) Select ‘Play Waveform Audio’ from the Audio menu. (Or on Mac use the ‘Play Waveform Audio’ button, and in iOS tap the waveform graphic)

Screen Recording Catalina: Screen recording fixed for Catalina - access the screen recorder from the File menu - The current audio data, as well as the processed samples for graphics modulation, is stored in a Spectra settings file enabling playing of the audio within Spectra. To play the audio: In the 'My Settings' pane of Presets click-right on a row to display the row actions menu: Play, Rename, Delete and select 'Play'. If there is no audio to play you are told so - for example old settings files will not contain audio. Note: When loading settings the audio data is not used to replace the current audio being used by Spectra. But since you can now play the audio that was the current audio at the time the settings were saved you can recall what it was. - Also : new isosceles triangle option, save Spectra to video, mask images by spectra, use images for color, composing spectra via backgrounds

Fixed an issue with the 'My Settings' table where the table experienced inadvertent scrolling after selecting a setting. Previous updates: Improved Performance: Settings data is cached to handle the increased load from incorporating background images and waveform audio files. Most notably the presets table scrolls more smoothly, but other methods that use settings data is faster. Background Preview in Settings: The background image can be previewed from the user settings table. (Swipe on a row in iOS, right(control)-click on a row in macOS.) Open Settings Options: Opening settings is more discriminate - if current settings has background, but new settings do not then an alert is presented because the existence of a background could mean the spectra does not look as expected unless you change the background settings. Play Waveform Audio: The current waveform audio file can be played (if it exists; a waveform graphic only displays the audio samples, and its presence does not mean there is an audio file associated with it.) Select ‘Play Waveform Audio’ from the Audio menu. (Or on Mac use the ‘Play Waveform Audio’ button, and in iOS tap the waveform graphic) No Background Image: The background image preview will now show a ‘no background’ image graphic if there is no background image. Apply Audio File Option: When opening settings with an audio file contained you have the option to ‘apply’ the audio file. This means that the file is read and stored as the current audio file for the waveform. This way if the settings are changed and saved a copy of the same audio can be included. (Audio is saved so that you can recall the audio by playing it from the user setting table.) Save Audio Option: Saving settings presents the option to NOT save the current waveform audio file. Saving the audio file is for two purposes: 1. So that you can recall the audio by playing it from the user setting table. 2. So that if you load setting with an audio file you apply it so it may be included when saving a modified version of the settings. New User Settings Table Row Labels: Labels in the user settings table indicate : contains audio data file, creation date and data size of the file. New Labels & Colors For Clarity: New terminology adopted: ’Mask the spectra by the background image or vice versa. Implements 'white on alpha' masking, where white is transparent.' This is to emphasize the intended usage of the ‘White’ color in the color pane, and the use of the ‘Invert’ operation for masks. Mask Inversion: Masks can be inverted. This is intended for use with ‘white on alpha masks’ - namely masks created as white with transparency. Choose the ‘White’ color option for a spectra and then save it as a background for masking.

Previous updates: - Saving and restoration of Spectra settings supports background images and all background image options : show, fill and mask. Note: when using an image as a mask white is transparent while other colors have varying amount of opacity. - Settings tables modified for displaying white spectra (intended for use as background masks), and items labelled to indicate if contains a background image. - When opening settings with a background 3 options are provided - ignore it, replace the current, or combine it with the current. - Background can be masked by spectra (as well as spectra masked by background) - 13 new audio ring tones - FIX - When saving current spectra as a background any masking was ignored. - Masking with a background is faster. - Backgrounds have a new option to 'fit or fill' the spectra background - default is original 'fit'. The option is available in the Background pane, and applies to drawing and masking with the background. - Color generation displays a color swatch for each color. - Background image options for showing and masking are restored on app launch. Background images are used for compositing spectra and masking. See demo videos ‘Composite Spectra’ and ‘Mask Background Image’ - Spectra can now be saved as video - frames of the video display the process of drawing the spectra. - In the Lines pane there is a new option to draw using Isosceles triangles. - Added support for background images managed from the new ’Background’ tab. - A background image can be loaded from a file, set from the current spectra (including its current background), or the current video frame. - Spectra can be composed using background images. See demo video ‘Composite Spectra’ - Background image can be used as a mask for the current spectra: white is transparent, black is opaque, intermediate is semi-transparent. A new color option in the color pane called ‘White’ intended to be used for creating background masks from a spectra. See demo video ‘Mask Background Image’ - A new color option in the Color pane called ‘Image’ will load a subset colors from a selected image file. See demo video ‘Image For Color’ - In the size pane there is a new option to draw a grid. The grid size matches the spectra width and height parameters. - The preview background can be set to a texture to help view spectra using background masks that are white - available in the ‘Size’ pane. - New builtin presets using the new Isosceles triangles option in the Lines pane have been added. - During screen recording the option to not record the cursor has been fixed. New: Apply dash pattern to lines. Dash length and spacing is adjustable. Access from the Lines palette of parameters.
