透過網頁讀取PSD後,依圖層輸出PNG檔案
在前面介紹過網頁可以讀取PSD檔案並擷取到該檔案的資訊,接著我們會希望能透過網頁上傳PSD檔之後,依照圖層來輸出圖片,同樣是利用PSD.js來輔助進行,可以透過我們製作的範例頁面來進行輸出測試。
預設輸出效果
透過PSD.js可將PSD內的各圖層輸出成PNG圖檔,亦可轉成Base 64圖檔格式,惟輸出時每個圖檔的尺寸並不會根據整體PSD檔大小來配置。

<!DOCTYPE html> <html> <head> <title>psd.js image example</title> <style type="text/css"> body, html { padding: 0; margin: 0; } #dropzone { width: 500px; height: 100px; border: 1px #ababab dashed; margin: 50px auto; } #dropzone p { text-align: center; line-height: 100px; margin: 0; padding: 0; } #image { text-align: center; } </style> <script type="text/javascript" src="psd.min.js"></script> </head> <body> <div id="dropzone"> <p>Drop PSD here</p> </div> <div id="image"></div> <pre id="data"></pre> <script type="text/javascript"> (function () { const PSD = require('psd'); document.getElementById('dropzone').addEventListener('dragover', onDragOver, true); document.getElementById('dropzone').addEventListener('drop', onDrop, true); function onDragOver(e) { e.stopPropagation(); e.preventDefault(); e.dataTransfer.dropEffect = 'copy'; } function onDrop(e) { e.stopPropagation(); e.preventDefault(); PSD.fromEvent(e).then(function (psd) { for (var i = 0; i < psd.layers.length; i ++){ document.getElementById('image').appendChild(psd.layers[i].image.toPng()); } }); } }()); </script> </body> </html>
依照整體PSD配置進行輸出
我們希望讓每個圖片在輸出後能保時相同的尺寸,也就是依照PSD的畫布大小來輸出每一張圖檔,但在原生PSD.js中並不具備這樣的功能,於是我們透過下述的方式來達成:
- 擷取PSD資訊並將圖檔轉為Base 64格式
- 產生與PSD尺寸大小相同的HTML Canvas
- 將產生的Base 64圖檔,依照原始位置放入Canvas中
- 將Canvas轉成PNG圖檔

可以參考我們製作的範例頁面
<!DOCTYPE html> <html> <head> <title>psd.js image example</title> <style type="text/css"> body, html { padding: 0; margin: 0; } #dropzone { width: 500px; height: 100px; border: 1px #ababab dashed; margin: 50px auto; } #dropzone p { text-align: center; line-height: 100px; margin: 0; padding: 0; } #image { text-align: center; } </style> <script type="text/javascript" src="psd.min.js"></script> </head> <body> <div id="dropzone"> <p>Drop PSD here</p> </div> <div id="image"></div> <pre id="data"></pre> <script type="text/javascript"> (function () { const PSD = require('psd'); document.getElementById('dropzone').addEventListener('dragover', onDragOver, true); document.getElementById('dropzone').addEventListener('drop', onDrop, true); function onDragOver(e) { e.stopPropagation(); e.preventDefault(); e.dataTransfer.dropEffect = 'copy'; } function onDrop(e) { e.stopPropagation(); e.preventDefault(); PSD.fromEvent(e).then(function (psd) { const PSDWidth = psd.tree().width; const PSDHeight = psd.tree().height; for (var i = 0; i < psd.layers.length; i ++){ const img = new Image(); img.src = psd.layers[i].image.toBase64(); console.log(psd); const layerWidth = psd.layers[i].width; const layerHeight = psd.layers[i].height; const layerLeft = psd.layers[i].left; const layerTop = psd.layers[i].top; const canvas = document.createElement("canvas"); canvas.setAttribute('class', "canvas"); canvas.width = PSDWidth; canvas.height = PSDHeight; console.log("canvas :", canvas); img.onload = function(){ canvas.getContext("2d").drawImage(img, layerLeft, layerTop, layerWidth, layerHeight); document.getElementById('image').appendChild(canvas); } } }); } }()); </script> </body> </html>
PSD檔案輸出限制
1. 無法輸出帶有效果的圖片
在PSD中我們可能會針對圖層套用一些效果,例如:陰影、光暈、筆畫…等等,但在輸出後的圖檔將不會帶有這些效果。

![](https://cloudlab.tw/wp/wp-content/uploads/2020/04/unnamed-file.png)
解決方法:透過點陣化圖層效果,即可輸出相對應的圖檔。
2. 無法輸出帶有遮色片效果的圖片

![](https://cloudlab.tw/wp/wp-content/uploads/2020/04/unnamed-file.png)
解決方法:將圖層轉為智慧型物件,即可輸出相對應的圖檔。
3. 無法依圖層混合模式輸出圖片

Caesars Entertainment is the largest casino company in the United States. It has launched real money casino games in several states, including at NJ online casinos, Pennsylvania casinos and Michigan online casinos, and it is poised to expand across the country in the years ahead. Online casino referral bonuses are rewards given to players who refer their friends to sign up and play at an online casino. Referral bonuses are less common than welcome bonuses, but many real money online casinos offer them. There are two types of referral bonuses: cash bonuses and free play. Players must send their unique referral link to their friends via email or social media to claim a referral bonus. It’s a given that when you place a bet at a casino, you’re not going to win every time. To ensure that games are based on true luck and skill, trustworthy online casinos use special Random Number Generator (RNG) software that makes sure the results of games are completely random and fair. Malicious casino sites, however, do not employ RNG technology and heavily rigg their games in a way that players can almost never win.

Not really. Bonus abuse is when an online casino player gets free money from an online casino by finding loopholes in the terms and conditions. Michigan online casinos have closed these loopholes (as far as we know), and simply making sure you follow the terms and conditions ensures you avoid being accused of bonus abuse. This article discussed online casinos with no minimum deposit, including their advantages and disadvantages and the available bonuses and promotions. In addition, we discussed how low deposit casinos could be a good option for players who want to gamble on a budget or try new casinos or games without risking too much money. A no deposit bonus works slightly differently, in that you’ll receive bonus credits rather than spins. You can play table games or video poker if the casino in question allows that, or stick to slots. Again, you’ll have to meet the terms if you want to claim your winnings. However, the wagering requirement can often be lower for a no deposit bonus than for free spins.
