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

2011/07/22

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

2011/07/222011/07/22

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.

Question about pdfprint tray selection – OK!

2011/07/22

I have a problem with the option -chgbin of the pdfprint product, the printer doesn’t react as I expect.

I start with the command:

pdfprint -listbins -printer "\\FS07-1\Xerox Global Print Driver PCL"

The output is:

Available bins/trays in "\\FS07-1\Xerox Global Print Driver PCL" printer:

15: Automatically Select

4: Bypass

260: Tray 1

259: Tray 2

258: Tray 3

257: Tray 4

After that I tried to select Tray 4 with this command-line:

pdfprint -chgbin 257 -printer "\\FS07-1\Xerox Global Print Driver PCL" "c:\temp\document.pdf"

I also tried the opion –papersource “Tray 4” …, but that didn’t work either.

It works fine when I use Adobe Reader to open this file and select tray 4 in the printerproperties and print it.

I hope you have a solution for me!

=================================

Please by following solutions to try again,

1. Please add -debug parameter,

2. Please use IP address to instead of computer name,

3. Please give full control permission to Everyone user account to this network printer,

pdfprint -debug -chgbin 257 -printer "\\192.168.1.10\Xerox Global Print Driver PCL" "c:\temp\document.pdf"

if you still have same problem, please email to us the log message, after we checked the log message, we will figure out a solution to you asap.

VeryPDF

=================================

Thanks for your response.

I tried all your suggestions and it works! The solution was to change the permissions for ‘Everyone’.

After I changed that, there was a line the log Found bin/tray by number, [257, Tray 4],

See the attachment for the debug info.

With regards,

=================================

Thanks for your great information.

Have a nice day!
