シェイプを画像にエクスポート

SpreadJSでは、基本シェイプ、コネクタシェイプ、またはシェイプのグループを画像としてエクスポートすることができます。

シェイプまたはシェイプベースのオブジェクトを取得した後、shape.toImageSrc() APIを使用して画像ソースを取得できます。 次のサンプルコードを使用して、シェイプの画像ソースを取得することができます:
<template> <div class="sample-tutorial"> <gc-spread-sheets class="sample-spreadsheets" @workbookInitialized="initSpread" > </gc-spread-sheets> <div class="options-container"> <div class="option-row"> シェイプを選択する: </div> <div class="option-row"> <img id="selectShapeImage" src="" alt="Original Image"> </div> <div class="option-row"> <input type="button" id="downloadButton" value="画像にエクスポート"> </div> </div> </div> </template> <script setup> import GC from "@mescius/spread-sheets"; import { ref, createApp } from "vue"; import "@mescius/spread-sheets-vue"; import "@mescius/spread-sheets-shapes"; import '@mescius/spread-sheets-resources-ja'; GC.Spread.Common.CultureManager.culture("ja-jp"); const spreadRef = ref(null); async function initSpread(spread) { spread.suspendPaint(); spread.setSheetCount(1); const loadingTip = addLoadingTip(); const res = await fetch('$DEMOROOT$/ja/sample/features/shapes/shape-toImage/spread.json'); await spread.fromJSON(await res.json()); loadingTip.remove(); spread.resumePaint(); bindShapesEvent(spread); initPanel(spread); } function addLoadingTip() { const div = document.createElement('div'); div.style.position = 'absolute'; div.style.inset = '0'; div.style.display = 'flex'; div.style.alignItems = 'center'; div.style.justifyContent = 'center'; div.style.background = 'white'; div.style.zIndex = '100'; div.textContent = 'Loading data from server ...'; document.body.appendChild(div); return div; } function bindShapesEvent(spread) { let shapeName; spread.bind(GC.Spread.Sheets.Events.ShapeSelectionChanged, function (event, args) { let shape = args.shape; if (!shape) { return; } let url = shape.toImageSrc(); shapeName = shape.name(); let imgElement = document.getElementById("selectShapeImage"); let img = new Image(); img.onload = function () { if (img.width <= 250 && img.height <= 250) { imgElement.style.width = "auto"; imgElement.style.height = "auto"; imgElement.src = url; } else { if (img.width > img.height) { imgElement.style.width = "250px"; imgElement.style.height = "auto"; } else { imgElement.style.width = "auto"; imgElement.style.height = "250px"; } imgElement.src = url; } }; img.src = url; }); document.getElementById("downloadButton").addEventListener("click", function () { let imgElement = document.getElementById("selectShapeImage"); let imgUrl = imgElement.src; let a = document.createElement("a"); a.href = imgUrl; a.download = shapeName + ".png"; document.body.appendChild(a); a.click(); document.body.removeChild(a); }); } function initPanel(spread) { let sheet = spread.getActiveSheet(); let shape = sheet.shapes.all()[0]; shape.isSelected(true); let url = shape.toImageSrc(); let imgElement = document.getElementById("selectShapeImage"); imgElement.src = url; } </script> <style scoped> .sample-tutorial { position: relative; height: 100%; overflow: hidden; } .sample-spreadsheets { width: calc(100% - 280px); height: 100%; overflow: hidden; float: left; } .options-container { float: right; width: 280px; padding: 12px; height: 100%; box-sizing: border-box; background: #fbfbfb; overflow: auto; } .option-row { font-size: 14px; padding-left: 5px; } .divide-line { width: 100%; height: 1px; background: #cbcbcb; margin-top: 10px; margin-bottom: 3px; } .title { text-align: center; font-weight: bold; } label { display: block; margin-top: 15px; margin-bottom: 5px; } p { padding: 2px 10px; background-color: #f4f8eb; } input { width: 160px; margin-left: 10px; display: inline; } select { width: 160px; margin-left: 10px; display: inline; } textarea { width: 160px; margin-left: 10px; } body { position: absolute; top: 0; bottom: 0; left: 0; right: 0; } #app { height: 100%; } </style>
