JPClark3 Blob toPDF function
I'm attempting to use the Blob.toPdf function sending in an HTML string. The resulting PDF is not very well formatted.
In the code below, I'm attempting to create a couple of tables and line up columns. The html works when I perform the "RenderAs=PDF" in a visual force page. I'm trying to replicate that using the Blob.toPDF() function.
Here is the test program I'm trying to run. If you paste this into an apex class, you can cut an paste the code inside the "testBlobPDF" and in an anonymus window and execute.
/**
* Testing the ability to convert a string to a PDF file.
*/
@isTest
public class testBlobToPDF
{
public static testMethod void testBlobPDF()
{
string PDFBody = testBlobToPDF.Body();
Blob pdfBlob = Blob.toPDF(PDFBody);
testBlobToPDF.SaveBlobToDoc(pdfBlob);
}
public static void SaveBlobToDoc (Blob blobPDF)
{
string FileName = 'TestPDF';
Document doc;
list<Document> docs = [Select ID, Name, Body, FolderID, DeveloperName, Type, ContentType From Document Where Name = :FileName];
if (docs.size() > 0)
doc = docs[0];
else
{
doc = new Document();
doc.Name = FileName;
doc.DeveloperName = FileName;
doc.Type = 'pdf';
doc.ContentType = 'application/pdf';
doc.FolderId = UserInfo.getUserId(); //PLaces this into the persons Personal Folder
}
doc.Body = blobPDF;
upsert doc;
}
public static string Body()

I don't see a HTML or BODY tags. Not sure if that matters or not.
Does the PDF render and save properly as an attachment? Is the table structure rendered but the stylings aren't correct?
I have tested this with the Body and Html tags. When I add those tags, there is no difference in the output. The only time there is a difference is if I add the header tag in front of the body tag. If i do that, then the header (with style and title tags) is output into the PDF document in a very ugly jumbled mess.
I was playing with your code a little, and noticed one thing - all the whitespace inside the String is taken literally, I don't know if this is intended or not. E.g.:
There is A LOT of whitespace before "Christopher Miller". That is one possible reason why the layout is off.
Here's a side question though, how do you render that page as landscape? In Visualforce (renderAs=pdf), you just use this in the CSS:
@page { size:landscape; }However, if you include HTML, HEAD, and STYLE tags inside that Apex string, and add that landscape css there, it is being rendered to the page as text, and the page is still in portait mode.
