View 1 RepliesI need to be able to export PDF's that I am creating to JPEG, so that users can have a screenshot/thumbnail of the end product, which is faster than opening the whole PDF.
I am running this on an ASP.NET website running in Medium Trust in the Rackspace Mosso Cloud.
I have yet to find a library that will either work in Medium trust, or in the case of ABC PDF, which works great locally, wont load in Mosso. Maybe Mosso has a custom trust level?
I know that iTextSharp works on Mosso, but I haven't been able to figure how to "screenshot" a single page of a PDF, or export a page to JPEG.
<form id="form1" runat="server"> <div id="dvforimage"> <asp:TextBox ID="Txtimage" runat="server"></asp:TextBox> <b>This is text</b> <img id="imgforconvert" src="images.jpg" alt="img1" /> </div> <asp:Button ID="btnforimage" runat="server" Height="28px" Width="72px" Text="ok" onclick="btnforimage_Click" /> </form>
I want to convert all data present in div to jpeg.I mean image,text or whatever i write inside div tag.You have given me previous cod e which only convert text to image.
I need to write a routine which uploads a largish (2-4 meg) jpg photo and shrink it down to a small size. Adobe image ready does what I need but I need to develop it in my web application. Basically I need to reduce the image file size so it is web friendly.

I am trying to create double and number format cells in excel using NPOI library. I used code like
Dim cell As HSSFCell = row.CreateCell(j)
cell.SetCellValue(Double.Parse(dr(col).ToString))
In excel numbers are aligning right but when I check format it is showing in "General"
then I changed my code to like below
Dim cell As HSSFCell = row.CreateCell(j)
cell.SetCellValue(Double.Parse(dr(col).ToString))
Dim cellStyle As HSSFCellStyle = hssfworkbook.CreateCellStyle
cellStyle.DataFormat = HSSFDataFormat.GetBuiltinFormat("#,#0.0")
cell.CellStyle = cellStyle
Then While opening file it is giving error and also taking so long to open. But Excel format showing in "Number" error showing is like below.

The problem I have is that when I exported into Excel, the texts in column two (which is the Lable1 in the Gridview) does not work when applying Wrap Text in MS Excel 2007. I believed that there is something in the btnExcel_Click method causes the texts to appear as ## all the time regardless if I format the cell to Wrap Text. If I copy the cell and pasted into another sheet or cell as "Paste Values" then the texts showed up and wrap text is working. What could I have changed on the code behind so that it appears as plain texts in Excel?
