问题 I know this has been asked before, and I know you can do it via making a seprate page for each image. But thats not ideal for what I want. I want to do that age old thing of displaying multiple images from a db on the same page: echo "<table>"; echo "<tr class ='tablehead'><td>Name</td><td>Location</td><td>Review</td><td>Image</td><td>Thumb</td></tr>"; while ($row = mysql_fetch_array($query)) { echo "<tr>"; echo "<td>" . $row['user_fname'] . "</td>"; echo "<td>" . $row['user_location'] . "<

问题 I'm working with SVG text paths which I need to convert to regular HTML canvas. For that I'm converting SVG to a blob file and "downloading" it as an image. However it seems that while converting SVG to blob firefox breaks somewhere and text path is lost completely in the process. Here's a fiddle of the problem: http://jsfiddle.net/ne5s2r1d/ var image = new Image(); var serializer = new XMLSerializer(); var data = serializer.serializeToString(document.getElementById("w3SVG")); var blob = new

问题 I need to export pdf and image files from a column in SQL Server 2012. Jonas's 3-step process in "How to export an image column to files in sql server" is the clearest instruction I've found. I did everything exactly as he stated. Two notes: Where he says "your_db" in the BCP statement, you need database_name.schema_name.table_name. No line breaks are allowed. I was able to export files one at a time after this, but they were corrupt. The files were slightly smaller (by 1-15 KB) than the

问题 Background I'm trying to check if a contact image exists for a specific contact (and later to actually get it, much later). the query should be as minimal as possible and avoid un-needed memory usage. I've figured out this probably isn't possible using the normal way, so for now I'm using: final Uri lookupUri = Uri.withAppendedPath(ContactsContract.Contacts.CONTENT_LOOKUP_URI, contactKey); final Cursor contactCur = mContentResolver.query(lookupUri, new String[] { ContactsContract.Contacts._ID

问题 I have a legacy application that uses hibernate for mapping objects into a database. It uses the Hibernate Mapping XML file to do so. The java class contains two properties abc and def that implement java Serializable. The mapping is defined this way: <property name="abc" column="ABC" type="serializable" length="32672"/> <property name="def" column="DEF" type="serializable" length="32672"/> When I try to set this up with oracle, I get a nasty error "ORA-01754: a table may contain only one
