Problems with Htmltools.exe

Posted on
Dear Sirs,
we use your command line application "Htmltools.exe" for merging PDF files since 2006 without problems; we are very satisfied with.
Since yesterday we have a strange error message while runing the application; the print screen of this error is attached ("PDF merge error.jpg").
We have also noted, that this error occurs only with some PDF files, not with all files. I send to you 2 PDF files, which give this problem.
We tried to install the application on to another server just for testing if the problem is due to local situation (operating system, local running applications, updates, ....), with no chance: the same error appears on the screen. Worse: we have got another more message error, whose print screen is also attached ("System error.gif"). It is in italian; it reads more or less "htmltools.exe, application error. The instruction 0x.... refers to memory 0x.... The memory could not be -read-".

The command we used was:

htmltools -mergepdf "CS1.pdf|CS2.pdf" out.pdf
======================================
we have purchased the last version. Actually the problem is solved.
Thank you very much for the support.
======================================
we have installed the latest version of Htmltools.
We read the created PDF with 2 different programs: Adobe Acrobat and FoxIt. The first usage we have done with Acrobat was successfully.
Yesterday we have used FoxIt for read the created PDF for the first time (we have different programs, some work with Acrobat, others with FoxIt). As you can see (attachment is a print-screen of we see), the page is unreadable...
Do you know this problem? How can we resolve it? We have the latest version of FoxIt, v4.3.1.0118 (2011).
======================================
Can you view this PDF file correctly in Adobe Reader? If yes, it is indicate this is a problem of FoxIt, you can submit this PDF file to FoxIt and ask them to check where is wrong in their FoxIt Reader product, I think they will fix this problem to you quickly.

VeryPDF
======================================
I'm referring to this "old" problem with FoxIt.
We have in the meantime tried with a different reader. With this software the PDF has the same problem noted with FoxIt: the PDF is unreadable. That is: the problem is not with FoxIt specially, but with different PDF readers, supposedly with perhaps the only exception of Adobe Reader. We are therefore convinced that the problem lies more in the new version of Htmltools... (a new symbol table not compatible with all PDF readers...?)
We have additionally noted an important increase of the time in elaboration: the same job that ran with the previous version in 20/25 minutes now run in 140/160 minutes (2 hours and a half!). Do you have idea of the reason?
Thanks for your support
======================================
We apologize for any inconvenience this may have caused to you, we will research this problem shortly, we will try to include a fix for this problem into the next version of our product, we will let you know after the new version is available, thanks for your patience.

Could you please provide me with instructions (or a sample) to create a setup package from VB6 to install our "PDF2Image" application? Thank you in advance.

Regards,
====================================
Please refer to following VB sample code,

Private Sub Command1_Click()
Dim pagecount As Long
Dim strPDFFileName As String
Dim strTIFFFileName As String
Dim strMessage As String
strPDFFileName = "example1.pdf"
strTIFFFileName = "example1_out.jpg"
' Register PDF to Image Converter Library
PDFToImageSetCode "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"

pagecount = PDFToImageGetPageCount(strPDFFileName)
strMessage = strPDFFileName + " PageCount: "
strMessage = strMessage + Str(pagecount)
MsgBox strMessage
result = PDFToImageConverter(strPDFFileName, strTIFFFileName, "", "", 200, 200, 24, COMPRESSION_PACKBITS, 70, False, True, -1, -1)
result = PDFToImageConverter2(strPDFFileName, strTIFFFileName + "_2.tif", "", "", 200, 200, 1, COMPRESSION_PACKBITS, 70, False, True, -1, -1)
End Sub

You can also refer to entire VB example in the “example_vb” folder, if you have any question for this VB project, please feel free to let us know.

VeryPDF
====================================
Thanks for that answer but it wasn't what I expected. What I need to know is how to create a "Setup Package" that includes the "pdf2image.dll" file as part of the "CAB" files. VB6 provides you with a "Package & Deployment wizard" that allows you to include all the ActiveX components of an application. Must probably you have a example or the list of files that should be included in that "distribution package".

Thanks
====================================
Thanks for your message, we haven’t a tool to include PDF2Image.dll into a .cab package, we suggest you may search “cab creator” or “cab maker” in google, you will able to find some tools to create the CAB files.

VeryPDF
====================================
Could you please remind me how it is the installation of the PDF2image zip file in the server?

I'm struggling here with a zip file I downloaded from the website (https://www.verypdf.com/pdf2tif/pdf2image_sdk_trial.zip). The only thing I get is the "pdf2image.dll" (along with all the package). When I copy the file to my server and execute my application, the "pdf2image.dll" file it is not where to found. My VB6 app complains for the file and basically cannot find it. Is it something that I have to specify on the source code line or maybe have to register the .dll file myself? Please advise.
====================================
You can simple copy pdf2image.dll and dependent files to system32 folder or syswow64 folder, then you can call pdf2image.dll from your code to covert PDF files to image files easily.

You can copy pdf2image.dll and depend files to system32 folder or syswow64 folder, then you can call pdf2image.dll from your code to covert PDF files to image files properly.

You can also compile your VB code to EXE first, put this exe to the folder where pdf2image.dll exist, then your EXE can call pdf2image.dll correctly.

Looking for a tool to extract/replace text in PDF files

Posted on
I am looking for a tool that can extract texts from a PDF (no layout, just the texts), and also find/replace texts.

This is for a translation service that processes a PDF, extracts the text from the document. The texts are translated by professional translators, and then inserted back into the document (to replace the original).

I was wondering if one of your tools could be used to do this?

Thanks for your help.
============================
Thanks for your message, our PDF2TXT product can convert PDF file to text file, but it can't replace the text in original PDF file. However, we are planning develop a PDF Extract/Replace Text Command Line product in the future, we will let you know after this function is available.

PDF Text Replace Tool enables you to change or delete text in PDF files. PDF Text Replace Tool is a program which makes it possible for you to search for a specific word and/or phrase and replace them with other text contents. You can also delete test strings from PDF pages. PDF Text Replace Tool is support batch process, it can work on several PDF files at same time. You can just select several PDF files in application, PDF Text Replace Tool will look up inside of them and modify text contents. PDF Text Replace Tool is really a powerful text replacement utility for PDF files.

dither function when convert color PDF page to black and white TIFF file

Posted on
Hi we are having a problem converting the attached PDFs using the "asp_PDFToImageConverter2" method. Following are our parameters:

X Resolution: 200
Y Resolution: 200
Bitcount: 1
Grayscale: False
Compression: 4
Quality: 100

The attached zip files contains the source PDFs. The issue is that the resulting TIFF is deteriorated.
===========================
"asp_PDFToImageConverter2" method can convert your 001000000.pdf file to attached TIFF file, because your 001000000.pdf file contain color information, so "asp_PDFToImageConverter2" method will dither the colors in BW TIFF file, is this the problem that you point to? Do you wish disable the "dither" processing?

Also, we suggest you may use at least 600DPI when you need convert a color PDF file to BW TIFF file, then you will get a BW TIFF file at better quality.

VeryPDF
===========================
Yes, how do we disable dither processing, and will these affect other images that get processed. In other words, is this a setting that we can always have ON (to remove dither)? Thank you.
===========================
We have disabled the "dither" in the new version to you, please download the new version from following URL to try again,

Some information about Dithered Colors or Halftone technology:
===========================
Dithering, also named Halftoning or Color Reduction, is going to be the technique of rendering an image on a display device with fewer colors than are in the images. The quantity of different colors in an image or on a device is employed referred to as its Color Resolution. The term 'resolution' indicates 'fineness' and is employed to describe the level of detail in a digitally sampled signal. It actually is used most generally in referring towards the Spatial Resolution, which might be the fundamental sampling rate for digitized images. To give the look of a good deal more colors, and this is especially accurate of early monitors that could only display 16 pure colors, a approach named dithering was used to give the impression of a great deal far more colors. Once you create an image or text images which will contain an invisible background color, make the background color exactly exactly the same as your net web site (which need to have to be a Web Safe color). Or, pick a Web Safe color that comes quite close to your background color or background texture. The reason for this is when your application creates the internet image, typically it'll anti-alias (blend) the edge of the visible image towards the background color. In case you use a white background, by way of example, and your net site has a red brown background, you could see an annoying light colored fringe about your image. Making use of a World wide web Secure color, on the other hand, ought to produce a cleaner image. It truly is essential to emphasize here that dithering can be a one-way operation. When an image has been dithered, even though it could look like a superb reproduction with the original, information is permanently lost. Quite a few image processing functions fail on dithered images. For these factors, dithering ought to be regarded as only as a technique to produce an image on hardware at would otherwise be incapable of displaying it. The details representing an image ought to usually be kept in full detail.
======================================
In printing, a continuous tone image, for example a photograph, that has been converted into a black-and-white image. Halftones are designed by way of a method referred to as dithering, in which the density and pattern of black and white dots are varied to simulate diverse shades of gray.
======================================
A halftone image is produced up of a series of dots as opposed to a continuous tone. These dots might be various sizes, various colors, and occasionally even different shapes. Bigger dots are utilized to represent darker, much more dense locations with the image, whilst smaller dots are used for lighter places.

Halftone images use used in newspapers and magazines since it really is a a lot much more efficient strategy to print images. Considering that a halftone image is produced up of discreet dots, it demands considerably much less ink to print than a continuous tone image. As long as the resolution of the image (measured in LPI) is high sufficient, the dots appear as a continuous image to the human eye. Nevertheless, should you closely examine the images printed in a newspaper, you ought to be capable of see the dots that make up the halftone image.
