I have to build a website using asp.net 4.5 that requires editing features of TIFF,PDF files.
basically i want to be able to select files from a list. the file should open in an editor with preview and we have edit controls such as Brightness,Contrast,Sharpness,Deskew, Despeckle etc.
I have seen the annotation asp.net sample and tried to create a implementation.
How do i load a file that resides in a directory in asp.net into the GDViewer. also, a major issue is the lack of client side documentation for activex controls. i am trying to look at the annotation sample and figure out but i dont know what is what and why is it not working.
i tried implementing as this
Code: Select all
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
<style type="text/css">
#GdViewer1 {
height: 516px;
width: 397px;
}
</style>
<script type="text/javascript">
window.onload = function () {
var f=document.getElementById("GdViewer1");
f.DisplayFromHTTP_2("http://localhost:26191/InputTIFF/test.tif", "", "");
}
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<object id="GdViewer1" type="application/x-oleobject" classid="CLSID:9E512B80-09C9-46A6-8CB5-3BE89A8BDEC0">
<param name="BackColor" value="#e5e5e5" />
<param name="ZoomMode" value="2" />
Please enable ActiveX to see this GdPicture Object
</object>
</div>
</form>
</body>
</html>The TIFF files are located in the inputTIFF directory and this needs to open.
Also, supposing that i am able to fetch the file and show it and i make buttons to increase brigtness and decrease brigtness and i click on them which client side functions would i use? and how would the changes persist on the save location.?
This is the approach i have used. If i am missing any control or method that i should employ please giude me.Can this be done via code behind?
Please provide me a sample code if possible and please set up some javscript documentation for Active Controls.
