Elements of airplane performance, 2nd edition This book contains sixteen chapters and four appendices which form a compre-hensive teaching text on the subject of airplane performance. The fi rst seven chapters are designed to provide necessary background material in mechanics, aerodynamics, atmospheric science, air data instruments, and propulsion. In addi-tion, the appendices furnish basic data and information on the theory pertinent to a clear understanding of the different problems. Chapters 8-13, in particular, treat the point performance of the airplane, i.e., the performance that pertain to given point on the fl ight path. Finally, chapters 14-16 deal with what is known as the integral performance, indicating the performance items which are related to the course of the fl ight. The text is extensively illustrated and includes numerous worked examples.
The book is primarily intended to serve as a textbook in undergraduate engineering courses and as an instrument for selfstudy. Contents Preface 1. Basic concepts 2. The atmosphere 3.

When I first started working with PDF, I found the very hard to navigate.It might help you to know that the overview of the file structure is found in syntax, and what Adobe call the document structure is the object structure and not the file structure. That is also found in Syntax. The description of operators is hidden away in Appendix A - very useful for understanding what is happening in content streams.
If you ever have the pain of working with colour spaces you will find that hidden in Graphics! Hopefully these pointers will help you find things more quickly than I did.If you are using windows, allows you to browse the object structure to understand it. There is a free demo available that allows you to examine the file but not save it.
This may help shed a little light:(from page 11 of PDF32000.book)PDF syntax is best understood by considering it as four parts, as shown in Figure 1:. Objects. A PDF document is a data structure composed from a small set of basic types of data objects.Sub-clause 7.2, 'Lexical Conventions,' describes the character set used to write objects and othersyntactic elements. Sub-clause 7.3, 'Objects,' describes the syntax and essential properties of the objects.Sub-clause 7.3.8, 'Stream Objects,' provides complete details of the most complex data type, the streamobject. File structure.

The PDF file structure determines how objects are stored in a PDF file, how they areaccessed, and how they are updated. This structure is independent of the semantics of the objects. Sub-clause 7.5, 'File Structure,' describes the file structure. Sub-clause 7.6, 'Encryption,' describes a file-levelmechanism for protecting a document’s contents from unauthorized access.
Document structure. The PDF document structure specifies how the basic object types are used torepresent components of a PDF document: pages, fonts, annotations, and so forth.
Sub-clause 7.7,'Document Structure,' describes the overall document structure; later clauses address the detailedsemantics of the components. Content streams. A PDF content stream contains a sequence of instructions describing the appearance ofa page or other graphical entity. These instructions, while also represented as objects, are conceptuallydistinct from the objects that represent the document structure and are described separately.
Sub-clause7.8, 'Content Streams and Resources,' discusses PDF content streams and their associated resources.Looks like navigating a PDF file will require a little more than a passing effort. One way to get some clues is to create a PDF file consisting of a blank page. I have CutePDF Writer on my computer, and made a blank Wordpad document of one page. Printed to a.pdf file, and then opened the.pdf file using Notepad.Next, use a copy of this file and eliminate lines or blocks of text that might be of interest, then reload in Acrobat Reader. You'd be surprised at how little information is needed to make a working one-page PDF document.I'm trying to make up a spreadsheet to create a PDF form from code.

To extract text from a PDF, try this on Linux, BSD, etc. Machine or use Cygwin if on Windows: pdfinfo -layout somepdffile.pdfA plain text file named somepdffile.txt is created. The simpler the PDF file layout, the more straightforward the.txt file output will be.Hexadecimal characters are frequently present in the.txt file output and will look strange in text editors.

These hexadecimal characters usually represent curly single and double quotes, bullet points, hyphens, etc. Adobe engineering santa rosa. In the PDF.To see the context where the hexadecimal characters appear, run this grep command, and keep the original PDF handy to see what character the codes represent in the PDF: grep -a -color=always '0-90-90-9' somepdffile.txtThis will provide a unique list of the different octal codes in the document: grep -ao '0-90-90-9' somepdffile.txt sort uniqTo convert these hexadecimal characters to ASCII equivalents, a combination of grep, sed, and bc can be used, I'll post the procedure to do that soon.
