Among many fixes and minor updates these are the most important features in v8.2.0: Abstract render layer to make it easier to attack external draw engines Add LV_FLAD_OVERFLOW_VISIBLE. If enabled the children of an object won't be clipped to the boundary of the object Add ffmpeg decoder support to play videos and open a wide variety of image formats Add font fallback support Add gradient dithering support Add "monkey test" Add cmsis-pack support Add Grid navigation (lv_gridnav) The GPU support for NXP microcontrollers is still not updated to the new draw architecture. See #3052

多くの修正とマイナーアップデートの中で、これらはv8.2.0の最も重要な機能です。 外部の描画エンジンを攻撃しやすくするための抽象的なレンダリングレイヤー 追加しLV_FLAD_OVERFLOW_VISIBLEます。有効にすると、オブジェクトの子はオブジェクトの境界にクリップされません ffmpegデコーダーのサポートを追加して、ビデオを再生し、さまざまな画像形式を開きます フォントフォールバックのサポートを追加 グラデーションディザリングサポートを追加 「サルテスト」を追加 cmsis-packサポートを追加 グリッドナビゲーションの追加（lv_gridnav） NXPマイクロコントローラーのGPUサポートは、まだ新しい描画アーキテクチャに更新されていません。＃3052を参照

Overview

英文	自動翻訳
v8.1 is minor release so besides many fixes it contains a lot of new features too. Some of the most important features are Built in support for SDL based GPU drawing Much faster circle drawing in the software renderer Several 3rd party libraries are merged directly into LVGL. Add LVGL as an RT-Thread and ESP32 component	v8.1はマイナーリリースであるため、多くの修正に加えて、多くの新機能も含まれています。 最も重要な機能のいくつかは SDLベースのGPU描画のサポートが組み込まれています ソフトウェアレンダラーでのはるかに高速な円の描画 いくつかのサードパーティライブラリが直接LVGLにマージされます。 LVGLをRTスレッドおよびESP32コンポーネントとして追加します

lv_disp_drv_t, lv_indev_drv_t, lv_fs_drv_t needs to be static ...disp_buf... is renamed to draw_buf. See an initialization example here. No partial update if two screen sized buffers are set disp_drv->full_refresh = 1 makes always the whole display redraw. hor_res and ver_res need to be set in disp_drv indev_read_cb returns void. To indicate that there is more that to read set data->continue_reading = 1 in the read_cb

First and foremost, create a new lv_conf.h based on lv_conf_template.h. To try the new version it's recommended to use a simulator project and see the examples. When migrating your project to v8 Update the drivers are described above Update the styles Update the events Use the new layouts instead of lv_cont features Use lv_obj instead of lv_page See the changes in Colors The other parts are mainly minor renames and refactoring. See the functions' documentation for descriptions.

A possible use-case of this system is to remove the overflowing content from the rounded edges. It also allows drawing perfectly anti-aliased circles, lines, and arcs. Internally, the drawings happen by defining masks (such as rounded rectangle, line, angle). When something is drawn the currently active masks can make some pixels transparent. For example, rectangle borders are drawn by using 2 rectangle masks: one mask removes the inner part and another the outer part. The API in this regard remained the same but some new functions were added: lv_img_set_zoom: set image object's zoom factor lv_img_set_angle: set image object's angle without using canvas lv_img_set_pivot: set the pivot point of rotation The new drawing engine brought new drawing features too. They are highlighted in the "style" section. 戻る : Previous New style system 英文 自動翻訳 The old style system is replaced with a new more flexible and lightweighted one. It uses an approach similar to CSS: support cascading styles, inheriting properties and local style properties per object. As part of these updates, a lot of objects were reworked and the APIs have been changed. more shadows options: offset and spread gradient stop position to shift the gradient area and horizontal gradient LV_BLEND_MODE_NORMAL/ADDITIVE/SUBTRACTIVE blending modes clip corner: crop the content on the rounded corners text underline and strikethrough dashed vertical and horizontal lines (dash gap, dash_width) outline: a border-like part drawn out of the background. Can have spacing to the background. pattern: display and image in the middle of the background or repeat it value display a text which is stored in the style. It can be used e.g. as a light-weighted text on buttons too. margin: similar to padding but used to keep space outside the object Read the Style section of the documentation to learn how the new styles system works. 戻る : Previous GPU integration 英文 自動翻訳 To 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. Right now, only ST's DMA2D (Chrom-ART) is integrated. More will in the upcoming releases. 戻る : Previous Renames 英文 自動翻訳 The following object types are renamed: sw -> switch ta -> textarea cb -> checkbox lmeter -> linemeter mbox -> msgbox ddlist -> dropdown btnm -> btnmatrix kb -> keyboard preload -> spinner lv_objx folder -> lv_widgets LV_FIT_FILL -> LV_FIT_PARENT LV_FIT_FLOOD -> LV_FLOOD_MAX LV_LAYOUT_COL_L/M/R -> LV_LAYOUT_COLUMN_LEFT/MID/RIGHT LV_LAYOUT_ROW_T/M/B -> LV_LAYOUT_ROW_TOP/MID/BOTTOM 戻る : Previous Reworked and improved object 英文 自動翻訳 dropdown: Completely reworked. Now creates a separate list when opened and can be dropped to down/up/left/right. 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) arc: can draw background too. btn: doesn't store styles for each state because it's done naturally in the new style system. 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) 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. linemeter, gauge: can have background if the related style properties are set. Padding makes the scale/lines smaller. scale_border_width and scale_end_border_width allow to draw an arc on the outer part of the scale lines. gauge: lv_gauge_set_needle_img allows use image as needle canvas: allow drawing to true color alpha and alpha only canvas, add lv_canvas_blur_hor/ver and rename lv_canvas_rotate to lv_canvas_transform textarea: If available in the font use bullet (U+2022) character in text area password 戻る : Previous New object types 英文 自動翻訳 lv_objmask: masks can be added to it. The children will be masked accordingly. 戻る : Previous Others 英文 自動翻訳 Change the built-in fonts to Montserrat and add built-in fonts from 12 px to 48 px for every 2nd size. Add example CJK and Arabic/Persian/Hebrew built-in font Add ° and "bullet" to the built-in fonts Add Arabic/Persian script support: change the character according to its position in the text. Add playback_time to animations. Add repeat_count to animations instead of the current "repeat forever". Replace LV_LAYOUT_PRETTY with LV_LAYOUT_PRETTY_TOP/MID/BOTTOM 戻る : Previous Demos 英文 自動翻訳 lv_examples was reworked and new examples and demos were added 戻る : Previous New release policy 英文 自動翻訳 Maintain this Changelog for every release Save old major version in new branches. E.g. release/v6 Merge new features and fixes directly into master and release a patch or minor releases every 2 weeks. 戻る : Previous Migrating from v6 to v7 英文 自動翻訳 First and foremost, create a new lv_conf.h based on lv_conf_template.h. To try the new version it suggested using a simulator project and see the examples. If you have a running project, the most difficult part of the migration is updating to the new style system. Unfortunately, there is no better way than manually updating to the new format. The other parts are mainly minor renames and refactoring as described above. 戻る : Previous
