Hi,

I'm trying out Quick PDF for an iOS app that would use some reasonably detailed geospatial PDF files.

When using code like:

let tempDir = NSTemporaryDirectory()
let sourcePath = NSBundle.mainBundle().pathForResource("example_Geo_PDF", ofType: "pdf")
let loadResult = debenu.LoadFromFile(sourcePath, "")
let renderResult = debenu.RenderDocumentToFile(72, 1, debenu.PageCount(), 1, tempDir + "example_Geo_PDF.png")

The render has a couple of problems that I'm not yet sure how to fix.

Many shapes are drawn outside what should be their bounding box. Example:

http://postimg.org/image/jbbkj43sl/" rel="nofollow - Render

I also have two maps that use thin lines for contours and outlines, but when rendered at higher DPI the lines are so fine they can barely be seen. I cannot provide the PDF documents for them :(

I saw a line thickness option under SetGDIPlusOptions, is there something like that for iOS?

Bump. No ideas? Maybe something to do with the order in which objects are drawn?

perhaps you should post it into the official support page from Debenu:
