I have a routine to generate png images from a form (1 to 35 image).
I need to append a variable number of this images for printing.Maybe appending on a single pdf or any kind of document, the goal is to automate printing. I can figure out how to print one by one, but i need to use a A4 page (4 images per page). Do you know anything about this, i have been trying with PdfSharp but i cant't figure out how to do this.
Any suggestion, link or code is welcome.
Thank you. Best regards
Diego Porras
A developer gave me this code for concatenate images (in my code I use png formatted images but you might change image format)I have made small fixes myself and this is the result):

This is my first question here, I tried to search for something like this, but couldn't find much.
So, I got about 200 old PSDS that have an outdated version of some images (Blurry and in low resolution), but they have text layers, and some retouching layers. And I managed to scan and get way better quality images, but I need to paste them one by one into the PSDS so I can align them and recycle the text and retouching layers, so I was wondering if there's a way to sorta automate the image copy-paste.
The file names are something like this:
old_psd_0001.psd, old_psd_0002.psd, old_psd_0003.psd...
new_png_0001.png, new_png_0002.png, new_png_0003.png...
I'm trying to do a copy pasting image script, all the other aligning and cropping work is automated with actions.
Thanks to anyone able to help.
Currently I want to create an application.multiscreen transitionstrong text
But I have a problem I do not know how to do these lines that divide the image into several parts. I want to cut the image into several parts and these parts you can handle, please at least some ideas.
If you want to split images up programmatically you are first going to have to choose a file format to support. I suggest PNG to begin with because their encoding is fairly simple to understand (see HERE) and c# has a class to decode it (see HERE.)
You'll want to think of the PNG file as a matrix of RGB values that you can split up and store into separate new smaller PNG files.
If you want to support other image file types you will have to do some research into their encoding formats and handle them differently.
Well I did. Of course other method as I create a WPF application. show image
This program is intended to control 3, 6 and 9 monitors connected by Raspberry Pi. As you can see in the image I want to first grid to have 2 buttons. The first button to set the image resolution of first grid. The second button can send images from the first grid to the first monitor and so on all grids.
Thank you very much for your help. Wait a few suggestions.
I found there is a lot of tools available for breaking the Big PDF files into smaller one by splitting the original PDF file PAGE WISE.for example, if i have a 10 page PDF Document,then we can able to break the original pdf file into 10 pieces in page wise splitting.
But i want similar kind of tool that breaks the PDF file smaller than the Page wise splitting.That means,i need to split the PDF page into different documents based on any parameter like paragraph,section,element...
for example,
If my PDF file having 2 pages with 10 paragraphs then i would like to split the pdf file into 10 separate Pdf file based on paragraph parameter...
Also, I strongly believe pdf does not contain any structure like Open XML.But i also Suspecting
How the tools can able to break the pdf files in to small pdf files by splitting page wise? What kind of mechanism they are using for page wise splitting PDF File?
So, Is there any way to do my work? Please give me your valuable suggestion on this?
PDF is a vector based document description language. It's page based so in a way every page is independent from the next one. Splitting page wise is therefore pretty easy. Contrary to a raster image where you can extract small subsets independently in a pdf you have to render the whole page to know how a small subset looks like.
Say you have a Page (black) which contains a complex shaped object (here it is a line but it could be any text, shape, image, etc.) and you want to extract a subset (red). You would have to first find all the objects that produce visible output in the region of interest. Then you would have to modify them so they are rendered correctly (in this case calculate the green points from the blue points while preserving the shape of the object).
An easier approach would be to include the whole page and clip the viewing area to the dimensions of the region.
You could do this with pdfjam. Check the --trim/--offset/--delta command in conjunction with a custom paper size (Example 6,7 on the pdfjam website). You would still have to somehow calculate the coordinates of the region of interest though.
I would like to know if its possible to convert a PDF to and image without fonts. My goal is to have only the image without text ?
And if yes, can I do it with ImageMagick/GhostScript ?
Here an example
The image final http://crocodoc_public.s3.amazonaws.com/8b8aa154-45e3-41f9-a465-628e1b2e955d/images/page-001.png
and the original PDF http://crocodoc.com/demo/efwpa (page 2) We can see that the text are on overlay over the image, what I want is to do the same.
So if I got you right, what you want is to remove some text from your PDF (not fonts), and you want to do it programmatically. I suspect you know already that this will only possible if the text is placed on some kind of separate layer in your PDF files. You can try to utilize iText for that. Beware, this will mean you will have to invest some days of learning how to use that library.
I too am the lookout for something like that.
While playing with imagemagick I tried this a command and got some unexpected results.
convert -input.pdf -blur 0x0 output.jpg
this removes the text layers from the pdfs I tried.
I cannot guarantee that this will work for you and if this the right way to achieve, but you may try.
You can do that with Adobe Acrobat. Select the text with the touch up tool and delete it. I don't think you can do that with Ghostscript. You could consider editing the PDF by hand (qpdf helps).
I have a scanned pdf document. The original document is handwritten and the paper used has a block grid in the background. I wanted to print the document and I was wondering if i could delete the background block filter of the paper and print just the written part.
Every image processing job is different so there may be many ways to do this. Can you first post a picture of the page so we can tell what could work and what wouldn't work.
Is the image in color or B/W ?
Are the lines a different color to the text ?
What resolution is the image scanned at ?
Is the image skewed ?
Most likely, you will need to convert the PDF to an image format and use an image processing function called line removal (with repair) to remove the lines. Unfortunatley the best solutions are commercial and not cheap.
