To do this LVGL renders the transformed widgets into a layer and draws that layer as an image applying all the transformations. Layers are also used when `opa` (not `bg_opa`, `border_opa`, etc) and `blend_mode` are set. This way nested objects are blended as one layer to avoid color bleeding. See more [here](https://docs.lvgl.io/master/overview/style.html#opacity-blend-modes-and-transformations). 353- **inherit and initial style properties** Besides setting "normal values" for style properties now you can set them to `inherit` (inherit the parent's value) and `initial` (set the system default). See more [here](https://docs.lvgl.io/master/overview/style.html#forced-value-inheritance-default-value) 354- **NXP-PXP and VGLITE GPU support** The support for NXP GPUs are added again 355- **Color font support** You can use emojis and images in texts with this great new features. See more [here](https://docs.lvgl.io/master/others/imgfont.html). 356- **ARM2D GPU support** Get support for ARM's own GPU. 357- **PubSub messaging** A publisher-subscriber based messaging system is added to make communication between components easier. See more [here](https://docs.lvgl.io/master/others/msg.html). 358- **Pinyin IME** Add support for Pinyin IME Chinese input. See more [here](https://docs.lvgl.io/master/others/ime_pinyin.html). 359- **render_start_cb** A new callback is added to `lv_disp_drv_t` to indicate when the rendering starts.

href="https://github.com/lvgl/lvgl/commit/29bfe604">29bfe604</a> 1613 1614## v8.0.0 (01.06.2021) 1615 1616v8.0 brings many new features like simplified and more powerful scrolling, new layouts inspired by CSS Flexbox and Grid, simplified and improved widgets, more powerful events, hookable drawing, and more. 1617 1618v8 is a major change and therefore it's not backward compatible with v7. 1619 1620### Directory structure 1621- The `lv_` prefix is removed from the folder names 1622- The `docs` is moved to the `lvgl` repository 1623- The `examples` are moved to the `lvgl` repository 1624- Create an `src/extra` folder for complex widgets: 1625 - It makes the core LVGL leaner 1626 - In `extra` we can have a lot and specific widgets 1627 - Good place for contributions 1628 1629### Widget changes 1630- `lv_cont` removed, layout features are moved to `lv_obj` 1631- `lv_page` removed, scroll features are moved to `lv_obj` 1632- `lv_objmask` the same can be achieved by events 1633- `lv_meter` added as the union of `lv_linemeter` and `lv_gauge` 1634- `lv_span` new widget mimicking HTML `<span>` 1635- `lv_animing` new widget for simple slideshow animations 1636- \+ many minor changes and improvements 1637 1638### New scrolling 1639- Support "elastic" scrolling when scrolled in 1640- Support scroll chaining among any objects types (not only `lv_pages`s) 1641- Remove `lv_drag`. Similar effect can be achieved by setting the position in `LV_EVENT_PRESSING` 1642- Add snapping 1643- Add snap stop to scroll max 1 snap point 1644 1645### New layouts 1646- [CSS Grid](https://css-tricks.com/snippets/css/a-guide-to-grid/)-like layout support 1647- [CSS Flexbox](https://css-tricks.com/snippets/css/a-guide-to-flexbox/)-like layout support 1648 1649### Styles 1650- Optimize and simplify styles 1651- State is saved in the object instead of the style property 1652- Object size and position can be set in styles too 1653 1654### Events 1655- Allow adding multiple events to an object 1656- A `user_data` can be attached to the added events 1657 1658### Driver changes 1659- `lv_disp_drv_t`, `lv_indev_drv_t`, `lv_fs_drv_t` needs to be `static` 1660- `...disp_buf...` is renamed to `draw_buf`.

2005 2006## v7.0.0 (18.05.2020) 2007 2008### Documentation 2009The docs for v7 is available at https://docs.littlevgl.com/v7/en/html/index.html 2010 2011### Legal changes 2012 2013The name of the project is changed to LVGL and the new website is on https://lvgl.io 2014 2015LVGL remains free under the same conditions (MIT license) and a company is created to manage LVGL and offer services. 2016 2017### New drawing system 2018Complete rework of LVGL's draw engine to use "masks" for more advanced and higher quality graphical effects. 2019A possible use-case of this system is to remove the overflowing content from the rounded edges. 2020It also allows drawing perfectly anti-aliased circles, lines, and arcs. 2021Internally, the drawings happen by defining masks (such as rounded rectangle, line, angle). 2022When something is drawn the currently active masks can make some pixels transparent. 2023For example, rectangle borders are drawn by using 2 rectangle masks: one mask removes the inner part and another the outer part. 2024 2025The API in this regard remained the same but some new functions were added: 2026- `lv_img_set_zoom`: set image object's zoom factor 2027- `lv_img_set_angle`: set image object's angle without using canvas 2028- `lv_img_set_pivot`: set the pivot point of rotation 2029 2030The new drawing engine brought new drawing features too. They are highlighted in the "style" section. 2031 2032### New style system 2033The old style system is replaced with a new more flexible and lightweighted one. 2034It uses an approach similar to CSS: support cascading styles, inheriting properties and local style properties per object. 2035As part of these updates, a lot of objects were reworked and the APIs have been changed. 2036 2037- more shadows options: *offset* and *spread* 2038- gradient stop position to shift the gradient area and horizontal gradient 2039- `LV_BLEND_MODE_NORMAL/ADDITIVE/SUBTRACTIVE` blending modes 2040- *clip corner*: crop the content on the rounded corners 2041- *text underline* and *strikethrough* 2042- dashed vertical and horizontal lines (*dash gap*, *dash_width*) 2043- *outline*: a border-like part drawn out of the background. Can have spacing to the background. 2044- *pattern*: display and image in the middle of the background or repeat it 2045- *value* display a text which is stored in the style. It can be used e.g. as a light-weighted text on buttons too. 2046- *margin*: similar to *padding* but used to keep space outside the object 2047 2048Read the [Style](https://docs.littlevgl.com/v7/en/html/overview/style.html) section of the documentation to learn how the new styles system works. 2049 2050### GPU integration 2051To better utilize GPUs, from this version GPU usage can be integrated into LVGL. In `lv_conf.h` any supported GPUs can be enabled with a single configuration option. 2052 2053Right now, only ST's DMA2D (Chrom-ART) is integrated. More will in the upcoming releases. 2054 2055### Renames 2056The following object types are renamed: 2057- sw -> switch 2058- ta -> textarea 2059- cb -> checkbox 2060- lmeter -> linemeter 2061- mbox -> msgbox 2062- ddlist -> dropdown 2063- btnm -> btnmatrix 2064- kb -> keyboard 2065- preload -> spinner 2066- lv_objx folder -> lv_widgets 2067- LV_FIT_FILL -> LV_FIT_PARENT 2068- LV_FIT_FLOOD -> LV_FLOOD_MAX 2069- LV_LAYOUT_COL_L/M/R -> LV_LAYOUT_COLUMN_LEFT/MID/RIGHT 2070- LV_LAYOUT_ROW_T/M/B -> LV_LAYOUT_ROW_TOP/MID/BOTTOM 2071 2072### Reworked and improved object 2073- `dropdown`: Completely reworked. Now creates a separate list when opened and can be dropped to down/up/left/right. 2074- `label`: `body_draw` is removed, instead, if its style has a visible background/border/shadow etc it will be drawn. Padding really makes the object larger (not just virtually as before) 2075- `arc`: can draw background too. 2076- `btn`: doesn't store styles for each state because it's done naturally in the new style system. 2077- `calendar`: highlight the pressed datum. The used styles are changed: use `LV_CALENDAR_PART_DATE` normal for normal dates, checked for highlighted, focused for today, pressed for the being pressed. (checked+pressed, focused+pressed also work) 2078- `chart`: only has `LINE` and `COLUMN` types because with new styles all the others can be described. LV_CHART_PART_SERIES sets the style of the series. bg_opa > 0 draws an area in LINE mode. `LV_CHART_PART_SERIES_BG` also added to set a different style for the series area. Padding in `LV_CHART_PART_BG` makes the series area smaller, and it ensures space for axis labels/numbers. 2079- `linemeter`, `gauge`: can have background if the related style properties are set.
