# Do you have a PDF To Image Converter COM for .NET program? .NET SDK for PDF to Image Converting

I am looking for information about including this in some software I am developing. I would like price and license structure.

Thanks for your message, PDF To Image Converter SDK Developer License is $1995.00, you can download and purchase it from our website directly, http://www.verypdf.com/app/pdf-to-image-converter/try-and-buy.html#buy-cvt-com http://www.verypdf.com/order.php?order=soft&s=102518&p=102518-4466287&q=1&v=0&d=0 Developer License Under one Developer License, you can integrate the corresponding SOFTWARE into your developed software and redistribute it with royalty-free. If the SOFTWARE contains source codes, you have the right to modify and reuse the codes under the Developer License. VeryPDF ————————————————– Do you have a native .Net version and if so, where can I find the documentation? I installed the demo of the COM SDK and while it worked, it was very slow. It was taking about 50 seconds per page using the default settings in the application. I need to find options that can speed up the processing. Thank you Customer ————————————————– We haven’t a native .NET version, PDF To Image Converter SDK can be called from .NET code without any problem. You can reduce bitcount and resolution, then you can convert your PDF file to image files quickly, for example, using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; using VeryPDF; using System.IO; namespace WindowsFormsApplication1 { public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void button1_Click(object sender, EventArgs e) { string appPath = Path.GetDirectoryName(Application.ExecutablePath); string strPDFFile = appPath + “\\test_files\\test.pdf”; string strOutFile = appPath + “\\_test_out.tif”; string strLicenseKey = “-$ XXXX-XXXX-XXXX-XXXX”;

string strCmd = “-r 100 -mono ” + strLicenseKey + ” \”” + strPDFFile + “\” \”” + strOutFile + “\””;

System.Type VeryPDFType = System.Type.GetTypeFromProgID(“VeryPDF.PDFtoImageCom”);
VeryPDF.PDFtoImageCom VeryPDFCom = (VeryPDF.PDFtoImageCom)System.Activator.CreateInstance(VeryPDFType);
string strReturn = VeryPDFCom.PDFToImageConverter(strCmd);
MessageBox.Show(“Converter finished.”);
}
}
}

“-r 100 -mono ” options will convert your PDF file to image files quickly, please to try.

Mono won’t work. The images need to be 256 shades of gray. Where can I get a list of options that I can pass so I can test various settings and try for one that works best with our system?

Ideally, I would need 256 grayscale, 300dpi images converted from pdf pages. Typically pages are PDF’s of an E size drawing (36″ x 48″).

You can use -gray option to create grayscale image files, for example,

private void button1_Click(object sender, EventArgs e)
{
string appPath = Path.GetDirectoryName(Application.ExecutablePath);
string strPDFFile = appPath + “\\test_files\\test.pdf”;
string strOutFile = appPath + “\\_test_out.tif”;
string strLicenseKey = “-$XXXX-XXXX-XXXX-XXXX”; string strCmd = “-r 100 -gray ” + strLicenseKey + ” \”” + strPDFFile + “\” \”” + strOutFile + “\””; System.Type VeryPDFType = System.Type.GetTypeFromProgID(“VeryPDF.PDFtoImageCom”); VeryPDF.PDFtoImageCom VeryPDFCom = (VeryPDF.PDFtoImageCom)System.Activator.CreateInstance(VeryPDFType); string strReturn = VeryPDFCom.PDFToImageConverter(strCmd); MessageBox.Show(“Converter finished.”); } Please refer to full options at below, C:\>pdf2img.exe PDF2Image Version 2.0 Convert PDF files to Image files, include TIFF, JPEG, GIF, PNG, BMP, EMF, PCX, TGA. etc. Web: http://www.verypdf.com/ Email: support@verypdf.com Build date: Apr 20 2011 Support raster image formats: 1.

I have been testing this for a few days. We are currently using another vendors product to do the PDF->Tiff conversion, but it is failing to convert a small percentage of the files our clients are needing. Your software converts all of them just fine, but takes over 5 times longer per page. Here is the code I am using with the demo software.

Dim strLicenseKey As String = “-\$ XXXX-XXXX-XXXX-XXXX”

Dim strCmd As String = String.Format(“-r 200 -gray -compress 5 “”{0}”” “”{1}”””, strPDFFile, strOutFile)
Dim sw As New Stopwatch
Dim VeryPDFType As System.Type = System.Type.GetTypeFromProgID(“VeryPDF.PDFtoImageCom”)
sw.Start()
Dim VeryPDFCom As VeryPDF.PDFtoImageCom = DirectCast(System.Activator.CreateInstance(VeryPDFType), VeryPDF.PDFtoImageCom)
Dim strReturn As String = VeryPDFCom.PDFToImageConverter(strCmd)
sw.Stop()
MsgBox(“Conversion finished. ” & sw.ElapsedMilliseconds.ToString)

We require 200DPI greyscale TIF images for our final application, ideally with LZW compression. I would like to not have to include two different PDF converters, but I don’t want to dramatically slow down most users just to help a few edge cases. Please let me know if there is anything that I can do to improve the performance.

We suggest you may choose JPEG as output format to try again, e.g.,

Dim strCmd As String = “-r 200 -gray D:\test.pdf D:\out.jpg”;

We hoping you can convert PDF file to JPEG format faster than TIFF format.

btw, the trial version will add some watermark test into output image files, these demo watermarks will speed more time if you have big and many output image files, because demo watermark function will need to add demo watermarks to these image files one by one.

You can also increase DPI and use -mono options to save the conversion time, e.g.,

Dim strCmd As String = “-r 300 -mono D:\test.pdf D:\out.tif”;

Our PDF2Image COM is support halftone technology for mono images, so the image files will be clear enough in black and white mode.
