# [Python]Plurk 回應截圖長圖
## 目標
~~1. 網頁截圖~~
~~2. 使用者登入，支援私噗~~
~~3. 按照回應截圖並且拼圖~~
~~4. 使用這可以設定長圖的最長長度，自動分割圖片~~
5. 使用元素的大小與座標進行圖片裁切
6. 使用Tk 作為簡易GUI 使用介面，減輕使用者的壓力
7. 使用pyinsaller 打包windows exe 上傳到dropbox

## 規劃
1. 單純直接最大瀏覽器高度 會出現bug
2. 打算固定瀏覽器的高度 並且用高度去進行計算要截圖幾次

## 目前使用到的Library
1. selenium
2. numpy
3. Pillow (PIL)
4. pyinstaller

## 第一版本

這種方法有極限最長的長度限制，可能要做成限制瀏覽器最長為單位去換算要拉幾次

## 第二版本

已經可以擷取並且拼圖超過500 回應的噗
目前的拼圖只是一般的拼圖，第三版本會採用以div為單位的截圖與拼圖，可能會拼出不同大小的圖片

根據li 元件的單位大小進行擷取
數量大小可以設定
接下來要製作使用者界面

## 第四版本
jquery highlight
include jquery in chrome console

[在Chrome的Console使用jQuery / How to include jQuery in Chrome's Console](http://blog.pulipuli.info/2017/01/chromeconsolejquery-how-to-include.html)

javascript:(function(e,s){e.src=s;e.onload=function(){jQuery.noConflict();$=jQuery;console.log('jQuery injected')};document.head.appendChild(e);})(document.createElement('script'),'https://code.jquery.com/jquery-latest.min.js')

修改暱稱的顏色，可以做到highlight 的效果

$("a:contains('暱稱')").css( "color", "顏色" );
$("*:contains('暱稱')").css( "color", "顏色" );
