blob

I am creating PDF files using blobs in Google Apps Script from a HTML code, but the problem is that HTML code has an image (referenced by "http") but the created pdf can't show it. This is my code function createBlobPDF(myMessage,myTitle){ var blobHTML = Utilities.newBlob(myMessage, "text/html", myTitle+ ".html"); var myPDF = blobHTML.getAs("application/pdf"); return myPDF; } Any solution? thanks!! If the images in HTML are loaded from URLs, the converted PDF file doesn't include the images. If you want to include the images in the converted PDF file, please put the images to HTML as base64

I'm using the following code to insert into a blob field: MySql.Data.MySqlClient.MySqlConnection conn; MySql.Data.MySqlClient.MySqlCommand cmd; conn = new MySql.Data.MySqlClient.MySqlConnection(); cmd = new MySql.Data.MySqlClient.MySqlCommand(); string SQL; int FileSize; byte[] rawData; FileStream fs; conn.ConnectionString = "server=192.168.1.104;uid=root;" + "pwd=root;database=cady234;"; fs = new FileStream(@"d:\Untitled.gif", FileMode.Open, FileAccess.Read); FileSize = (int)fs.Length; rawData = new byte[FileSize]; fs.Read(rawData, 0, FileSize); fs.Close(); conn.Open(); string strFileName =

i know some of you are going to say that this isnt the correct way but im on a tight deadline to finish an application and as of now i cant go back and modify the code to store the images in a directory. now that thats cleared the question i had is i inserted an image into the database by typing this. (dont mind the class security call, all that is doing is a few checks if the data is valid) $filename = $security->secure($_FILES['imgschool']['name']); $tmpname = $security->secure($_FILES['imgschool']['tmp_name']); $imgsize = $security->secure($_FILES['imgschool']['size']); $imgtype = $security

$serv = "xxx"; $user = "xxx"; $pass = "xxx"; $db = "xxx"; $imgloc = "../images/bg.jpg"; $image = fopen($imgloc, 'rb'); $imageContent = fread($image, filesize($imgloc)); $conn = new mysqli($serv, $user, $pass, $db); $sql = "INSERT INTO `image`(`advert_id`,`img`) VALUES('1','" . $imageContent . "');"; $conn->query($sql); I'm using the above code to try to insert binary into my MySQL database but nothing is being sent to the database. The $imageContent just appears in the database as null but if I echo $imageContent it seems to show binary data. advert_id is just a int field and img is a BLOB

I have a blob type field in my MySQL, I want to put the data in this field in JLabel as Icon. For example this JLabel will be user's Profile Picture in my form. I used this codes but nothing happens and also I want to fix to width or fix any image size in my jlabel DefaultTableModel pic = MyDB.DataTable("SELECT `Picture` FROM `photo` WHERE `Employee ID` = 'EQ0103'"); if (pic.getRowCount() > 0){ Blob blob = pic.getBlob(1); byte[] image1 = blob.getBytes(1, ALLBITS); ImageIcon image = new ImageIcon(image1); picture.setIcon(image); getContentPane().add(picture); setVisible(true); } picture is the

I'm using the HTML5 Blob API to download a file from a JavaScript client in a WebView based macOS application: /** * Save a text as file using HTML <a> temporary element and Blob * @author Loreto Parisi */ var saveAsFile = function(fileName,fileContents) { if(typeof(Blob)!='undefined') { // using Blob var textFileAsBlob = new Blob([fileContents], { type: 'text/plain' }); var downloadLink = document.createElement("a"); downloadLink.download = fileName; if (window.webkitURL != null) { downloadLink.href = window.webkitURL.createObjectURL(textFileAsBlob); } else { downloadLink.href = window.URL
