How can I write a script or program to manipulate Adobe Photoshop files? I'd like to be able to do something like read a Adobe PSD file, rename the layers, and save it back to a PSD format.
The files look to be saved with a combination of XML and serialized data. I looked at the file's code and see that it has <x:xmpmeta near the start, did some google searching to find the wikipedia article about xmp - Extensible Metadata Platform, but I'm unclear if that is the format for the entire file or just for the metadata portion.
I saw that there is a PSD parser class for PHP available, and not a bad article about how to use it, although it seems like it is just for reading / converting and not for writing / saving.
But I'd like to know:
What format are these files stored in?
Where are the guidelines for interfacing with that format?
Are there some classes / tools available for manipulating that file format? Any language would be fine for a start.
I'm happy to do more research on my own but I'm hoping for some guidance to know what I should be looking for.
I'm not familiar with it myself, but there is an official SDK for Photoshop available that should let you do all that and more with .psd files.
There are not so many options. The general advice would be to look into buying Adobe InDesign Server. In some cases it can be cost prohibitive and you might be interested in 3-party SDKs. Unfortunately there are a few options in the market. One of them is Graphics Mill image processing SDK (http://www.graphicsmill.com/photoshop-psd).

alright, I have a geojson file that is about 10MB, normal browser based editors fail for obvious reasons, so is there any geojson editor that is powerful enough to edit a 10MB file? and I am not talking about just a JSON editor.
I made in the past good experience with https://vector.rocks/.
It is an online GeoJSON editor that can work with large files. Disadvantageous is the limited functionality of the tool.
I would also check if you really need a 10MB file.
Depending on your application it might be worth compressing the file to make it easier to work with.
At https://mapshaper.org/ you can load a GeoJSON file (even very large files) and download it with reduced size but lower precision.
If both solutions are not suitable for you, you will probably have to get used to a professional GIS software.
Some of the most popular free softwares are:
QGIS (https://qgis.org)
gvSIG (http://www.gvsig.com/en/products/gvsig-desktop)
GRASS (https://grass.osgeo.org/)
They all can easily deal with 10MB files but it will but it will take you some time until you are used to the editing functions.
While designed for editing OSM, I find JOSM to also be a powerful desktop editor for large geoJSON files:
https://josm.openstreetmap.de/
You'll just want to be careful working with polygons, because JOSM doesn't directly support geoJSON polygons – they instead used a "closed way" linestring, but there is a patch:
https://josm.openstreetmap.de/ticket/17453
https://josm.openstreetmap.de/ticket/18902
Beyond polygons, JOSM is well suited for working with geoJSON linestrings and points
Context
A friend of mine is having trouble printing source code to a human readable format.
The compiled (I assume) programs of their welding robot have the .rpg extension. They want to collect print-outs in human-readable format, possibly for backup or future reference.
Their supplier can provide the software that accomplishes this, be it at a considerable cost (and possibly: an annual license). Because of this, my friend decided to ask me if a easier/cheaper solution exists.
Examples & Pictures
The files can be read on the console of the robot, an example:
I've done some minor research and I'm fairly sure this is the Report Program Generator (RPG) language developed by IBM. The Assembly-like syntax seems to match; it might be one of the later versions of the language.
My friend has send me an example .rpg file, the contents seem binary with some string literals scattered throughout. Screenshot of the contents of an example file in hexadecimal:
The Question
There is not much, if any, clear information to be found online so I suppose I have multiple questions (for anyone that might know more about this):
Is this (first image) Report Program Generator (RPG) code?
Does the .rpg file contain compiled or processed code? Maybe an intermediate format?
Is it possible to convert files as shown in the example, back to source-code or human-readable format, kind of 'disassemble' it?
If anyone knows more, don't hesitate to give me any information or ask more details if necessary. Thanks in advance!
And maybe not an important question but still something that bugs me (and might indicate I'm on the wrong track):
If this is indeed an RPG program, why would the compiled/processed binary have the .rpg extension, shouldn't the source-file have that? This leads me to believe I'm either (a) assuming the wrong things (the language, etc...) or (b) this is an intermediate format, easier for machines to read, that has to be interpreted by some kind of runtime system.
I don't think that's any version of IBM's RPG language. RPG does have a MOVEL opcode, but it doesn't have any of the others.
Also, all the versions of the IBM language have been intended for business programming. I doubt that it would have been used for robotics.
My guess is that's a proprietary language of the company that makes the robot.
There are some similarities but it does not look like IBM RPG language.
RPG sources are in fact source physical file members. They are not stored in the "traditional" file system but in OS/400 libraries. Therefore RPG sources have no extension. They can be converted to Integrated File System stream file though.
I can't answer this question I'm afraid as it's unknown language to me.
I expect possibly that the OP misidentifies the file type/extension; that the extension is actually .prg, and the files serve as instructions for a Panasonic Industrial Welding Robot. The following forum [drilled down to Panasonic Robots] bills itself as the biggest Industrial Robots Supportforum worldwide!; perhaps a good place to ask about those images provided in the OP, and the inquiry about getting source from what appears to be a binary instruction stream.
FWiW, the first image seems to show that the Ezed utility [on the console] gives that human-readable format, so then the question might be how to get that saved and then how to transfer that elsewhere; e.g. what type of comm ports and file transfer utilities are available from whatever platform/OS.
I am trying to make an application which make a editable document file(doc or pdf) from an image. I am planning to use tesseract for extraction of the text. But i am not yet sure how to get the basic formatting of the text(size,bold,italic,underline) & images that might be present in the document image. I am planning to use J2EE, to make a Web Based App(Have to use J2EE). I think i might be able to recognize the components and formatting of the document using OpenCV, but i am not really sure.
Given that you are planning to use Tesseract for the basic OCR capabilities, try looking into the hORC formatted output. That includes quite a lot of additional information about font-size, font-face, position, etc.
You can find a description of hOCR here:
https://docs.google.com/document/d/1QQnIQtvdAC_8n92-LhwPcjtAUFwBlzE8EWnKAxlgVf0/preview#heading=h.e903b9bca924
If that doesn't work out, it depends on how much effort you want to put into Tesseract. It's internal APIs (available in Java via Tess4J, among others) do provide much of the information that you would need to reconstruct the page layout.
I am playing around with Leadtools to see how it might benefit me but i am a little frustrated with their documentation regarding how the process works. I am creating a library with methods that take an input file, convert it to pdf, add a qrcode to the file and save it and then reading the qrcode again.
Does a pdf have to be converted to an image before leadtools is
able to read the qrcode?
Does leadtools allow converting from
doc to pdf and then adding the qrcode or do i have to convert it to
an image as well?
Is there anywhere I could look at code
samples of how I can go about doing what I talked about other than
the leadtools site itself?
I am sorry to hear that you are having difficulties, but I will do my best to get you pointed in the right direction.
To answer your questions:
A1.) Yes, the PDF will need to be rasterized before the LEADTOOLS barcode engine can be used. Our barcode engine will only work with raw image data. Once the file is decompressed into raw data, we will not access the file any further.
A2.) Yes, you can rasterize Microsoft Word documents using either our file I/O methods or with the LEADTOOLS Virtual Printer. Once you have the raw image data, you can pass it to the barcode engine to write the QR code into the data. Once the barcode is written, you can then compress the image into any supported format, including (raster) PDF. You can also create a searchable PDF by running the resultant image through an OCR engine & outputting to PDF.
A3.) The LEADTOOLS SDK has a main barcode demo that should illustrate the ability of the SDK to handle the features you describe here. There are also tutorials in the help file, and various projects on our support forums. We have also created a couple different CodeProject articles here:
Multi-Platform Barcode with LEADTOOLS 18
How to Read Barcodes from Images using LEADTOOLS
You haven't mentioned here what programming language you are developing with or what the specific problem are that you have encountered. Without knowing either of those, it's difficult to get more specific into any methods or other resources to check out. For a simple raster conversion of a Microsoft Word Doc to PDF and writing a barcode, I think this would probably take between 10-15 lines of code.
If you have not already, I would highly recommend sending an email to Support#leadtools.com or open a live chat with the LEADTOOLS Support team from LEADTOOLS.com. We can get into more specifics there and help you more directly with any issues you are encountering.

I tried adding this as a comment, but it is apparently too long for that. So I have added it as another answer.
Even if you are building a DLL, I would suggest starting out building a simple demo with a view of the image so you can see what exactly is happening to the image. Once you are comfortable that the image is being modified the way you want, then implement that code in your own library.
Also, I would recommend testing out the toolkit with the provided main demos. The demos are there to illustrate the different options you have access to in the code. If you can accomplish what your application or library will need to do through the demos, then it would be worth your time to begin coding specifically what you need. You might even need to use multiple demos to verify the tools can accomplish the goals that you have. You have all the toolkit code for the demos, so you can take them apart and use the specific pieces that you need in your application.
If you are having trouble identifying which demos to try out or whether the toolkit has the specific functionality that you need, your best bet is to contact Tech Support directly to ask. We are here to help get you pointed in the right direction.
To get down to brass tacks, the source of the image data is not all that important from the perspective of the barcode engine. It needs a RasterImage handle (raw image data) to write the specified barcode. Whether the image data is created on the fly, read from file, or generated from a scanner, it does not make a whole lot of difference.
To find the main .NET barcode demo, I would start out by going to the LEADTOOLS shortcuts. To get there, go to the Start menu -> LEADTOOLS -> Help and Demos. The shortcuts are broken down by programming language, feature, and then the base toolkit. You should be able to find the WinForms .NET barcode demo here:..\Shortcuts.NET Class Libraries.NET Framework\01 Imaging\07 Barcode
Our toolkit example is a .NET WinForms project, but it will work in ASP.NET also.
Here are some links to tutorials if you want to dig right into the code:
Loading and Displaying an Image in WinForms
Reading Barcodes
HOW TO: Load and Display an Image with WebImageViewer
There was also this recent code tip posted illustrating how to read and write UTF-8 characters in a QR barcode.
We provide both .NET 2.0 and .NET 4.0 DLLs for our barcode engine. Both of these work within Visual Studio 2012.
I know of the US GIS TIGER file format from years ago, but have never used it.
I'm very shortly going to need to very quickly implement simple geocoding and vector graphics of roads and other features.
Where do I go for information - are there tutorials, example queries, etc?
Are there other ways to include geocoding and basic mapping in a mobile (no internet) device?
-Adam
As far as I'm aware of, there aren't many applications that make use of the TIGER/Line format directly. Most apps use TIGER files that have been translated into ESRI's shapefile format.
Edited to add:
Is there information on ESRI's format available?
There's an ESRI whitepaper describing the file format.
If you're planning to use shapefiles in an application, there are various libraries out there.
The OpenStreetMap project imported TIGER data, you might find useful code snippets there. See the TIGER page on the OpenStreetMap wiki for more information and links
