Highlight Text By Search

This software can search for a list of user-specified words and phrases and automatically highlight them in the PDF document. Text can be highlighted with a single color or using 20 different automatically assigned colors (each search term is highlighted with a different color):

Fast and powerful hit highlighting for PDF

PDF Highlighter can mark terms in a document by a highlight configure file. Highlighter supports advanced search options including:

• Phrases and proximity search
• Wildcards
• Fuzzy search
• Synonyms
• Language specific text analysis (e.g. stemming) for 30 languages

Alternatively, instead of feeding Highlighter with search terms, the highlight file can be used to specify locations of text that should be marked in the document.

Multicolor hit highlighting

PDF Highlighter ensures that same terms are assigned the same color. The highlighter automatically assigns colors to different terms, making the document review process more user-friendly and efficient. The color coding feature makes PDF Highlighter ideal for document forensics and natural language processing (NLP) tools as well—where the number of marked terms is much higher than for simple user queries.

Batch PDF processing

Batch highlighter can automatically annotate all your PDF documents using a file containing predefined keywords and phrases. You can assign a color to each individual phrase and optionally a category tag. PDF file created by the tool will open on the first keyword occurrence. btw, Generated PDF can be opened in any PDF viewer.

Create keyword links automatically

With PDF Highlighter Command Line software, you can turn every occurrence of a particular word or phrase into an active hyperlink. For example, you could make all occurrences of your company name in your document link through to your company web site. The Auto Keyword Link tool gives you the choice of going through each occurrence and approving them one at a time, or you can just convert all occurrences automatically in the one go.

Links can be set to execute a variety of actions such as open a URL or external file, go to a specific page or named destination, or even the next instance of the word in the document.

We suggest you may download the trial version of PDF Highlighter Command Line software from our website for evaluation first,

If you encounter any problem with our software, please feel free to let us know, we will assist you asap.

## How to Create High Quality TIFF Images from a PDF File?

We were recently asked by a customer to help him get the best quality TIFF image from his PDF document. He wanted his TIFF image in color and also wanted to keep the size of his created TIFF image as small as possible.

You can see below the difference in the quality of the TIFF image first created, and the final result. The text in the second image has a much smoother and cleaner appearance.

The Customer's TIFF Image Requirements

1. The customer's first request was to maintain the quality of the initial PDF document.
2. The customer's second request was to keep the file size as small as possible. It is an unfortunate fact of life that TIFF images will be bigger than the PDF file they are created from. The resolution (or dots per inch) at which TIFF Image Printer creates the image plays a large part in the resulting file size. A TIFF image created with a resolution of 200 dpi will generally be 2 to 3 times larger in file size, and at 300 dpi the image can be 3 to 5 times larger.

How We Did It?

To get the quality of output the customer needed, and to keep the file size as small as possible, the resolution of the TIFF images was set to 120dpi. This resolution is the closest match to the screen resolution Adobe uses to display the text, meaning the created image will be the closest possible match to how the PDF looks when viewed in Adobe.

In order to convert from PDF file to TIFF image file from command line, you may download "PDF to Image Converter Command Line" from this web page,

http://www.verypdf.com/app/pdf-to-image-converter/try-and-buy.html#buy-cmd

http://www.verypdf.com/dl2.php/pdf2image_win.zip

after you download it, you can run following command lines to convert from your PDF file to TIFF image file at 120 DPI or 300 DPI,

pdf2img.exe -r 120 "D:\downloads\VeryPDF.pdf" "D:\downloads\VeryPDF.tif"

pdf2img.exe -r 300 "D:\downloads\VeryPDF.pdf" "D:\downloads\VeryPDF.tif"

In general, you will get a better TIFF image file with above command line if your PDF file is a standard A4 or Letter paper size.

However, if your PDF file has an non-standard paper size, above command lines may fail to convert from PDF file to TIFF file, for example, here is a sample PDF file, this PDF file's paper size is 10845 x 4274 pt, if you use 300DPI to render this PDF file to TIFF file, pdf2img.exe will use more memory and may cause a crash problem,

I tried following command line in my system,

pdf2img.exe -r 300 "D:\downloads\VeryPDF.pdf" "D:\downloads\VeryPDF.tif"

pdf2img.exe encountered a crash problem, here is the screenshot,

Please look at above screenshot, pdf2img.exe process had already used 1.38GB memory, if pdf2img.exe process want to use more memory, it crashed.

For such bigger paper size PDF file, you need reduce the DPI option in order use pdf2img.exe to convert this PDF file to TIFF file, for example,

pdf2img.exe -r 72 D:\downloads\VeryPDF.pdf D:\downloads\out.tif

However, if you want to create high quality image file from bigger paper size PDF file, you may use VeryDOC Postscript to Image Converter Command Line (ps2image.exe) application, VeryDOC Postscript to Image Converter Command Line (ps2image.exe) can be downloaded from this web page,

ps2image.exe application does use a temporary disk file to instead of memory, so it hasn't the limitation on the maximum number of memory usage, for example,

ps2image.exe -r 300 D:\downloads\VeryPDF.pdf D:\downloads\out.tif

As you see, the width and height of result TIFF image is 45188 x 17808 pt size, this image's dimension is big enough.

If you encounter any problem with pdf2img.exe or ps2image.exe application, please feel free to let us know.

## How to combine a text watermark with opacity into original image data in the PDF file to prevent deletion permanently?

Hi there,

How can I use img2pdf.exe with watermark options that products the result like the one I attached here?

I want combine the text watermark with opacity into original image data in the PDF file to prevent deletion permanently.

Thanks
Customer
------------------------------------

Thanks for your message, VeryPDF Image to PDF OCR Converter Command Line software has this function, you may download the trial version of Image to PDF OCR Converter Command Line from this web page to try,

after you download it, you can run "image2pdf-with-watermark.bat" for test purpose, this "image2pdf-with-watermark.bat" file will combine a demo watermark into a TIFF file and convert this TIFF file to PDF file again, the generated demo watermark can't be removed anymore, because it has been combined into original TIFF image permanently.

"image2pdf-with-watermark.bat" file contains following command lines,

imgconv.exe skew_test.tif -gravity Center -pointsize 200 -fill "rgba(255,0,0,0.3)" -annotate "315x315+0+0" "Unofficial-Internal Use\nonly" _out.png

img2pdfnew.exe     _out.png     _example.pdf

The first command line will comebine a text watermark into original TIFF image file, this text watermark has 30% opacity and red color, you can adjust the opacity and color to best meet your requirements.

Some more information about "-annotate" option,

Annotate an image with text

This is a convenience for annotating an image with text.

The values Xdegrees and Ydegrees control the shears applied to the text, while tx and ty are offsets that give the location of the text relative any -gravity setting and defaults to the upper left corner of the image.

Using -annotate degrees or -annotate degreesxdegrees produces an unsheared rotation of the text. The direction of the rotation is positive, which means a clockwise rotation if degrees is positive. (This conforms to the usual mathematical convention once it is realized that the positive y–direction is conventionally considered to be downward for images.)

The new (transformed) coordinates (x', y') of a pixel at position (x, y) in the image are calculated using the following matrix equation.

If tx and ty are omitted, they default to 0. This makes the bottom-left of the text becomes the upper-left corner of the image, which is probably undesirable. Adding a -gravity option in this case leads to nice results.

Text is any UTF-8 encoded character sequence. If text is of the form '@mytext.txt', the text is read from the file mytext.txt. Text in a file is taken literally; no embedded formatting characters are recognized.

If you encounter any problem with this software, please feel free to let us know.
