php - merging XFDF with PDF form to create final PDF server-side? -

-

this have currently:

  • user submits form data , gets "download pdf" link.

  • the link points script generates xfdf file on fly , outputs xfdf file after setting appropriate headers, etc.

  • the xfdf file points password-protected pdf, generic pdf form uses xfdf data fill in fields.

what like:

  • user clicks "download pdf" link.

  • xfdf generated on fly (no file written server).

  • pdf , xfdf merged server-side using generic pdf. contents of final pdf output user same xfdf originally.

  • neither xfdf nor final pdf ever saved server.

i looking @ pdftk, has few options dealing fdf/xfdf files, of assume a) original xfdf file exists file on server , b) resulting pdf should output file on server.

also, pdftk 4 years old.

i wondering if:

a) there newer equivalent pdftk out there?

b) if there way, using newer pdftk-like tool or using pdftk, use dynamic paths data never has exist in file form on server?

i learned built-in input/output streams using php:// i'm still fuzzy on how use it, maybe place this?

there commercial applications (you can find @ pdfstore.com), programming, can create own using same library pdftk using process pdf files: itext (http://itextpdf.com/) there .net version - itextsharp.

by doing that, can access data java or .net program, , never needs exist in file form, out of database directly.

you can recompile pdftk newer version of itext - way, can latest pdf processing capabilities , ease of use have pdftk. still need xfdf file however.

c++ - Convert big endian to little endian when reading from a binary file -

-
this question has answer here: how convert between big-endian , little-endian values in c++? 28 answers i've been looking around how convert big-endian little-endians. didn't find solve problem. seem there's many way can conversion. anyway following code works ok in big-endian system. how should write conversion function work on little-endian system well? this homework, since systems @ school running big-endian system. it's got curious , wanted make work on home computer also #include <iostream> #include <fstream> using namespace std; int main() { ifstream file; file.open("file.bin", ios::in | ios::binary); if(!file) cerr << "not able read" << endl; else { cout << "opened" << endl; int i_var; double d_var; while(!file.eof()) {...

linq to sql - Linq2EF: Return DateTime with a TimeZone Offset -

-
our database has times stored utc, , know user's current timezone, want return relative that. want incorporate offset in linq projection so: var users = u in this.context.users select new userwithcorrecteddate { id = u.id, firstname = u.firstname, lastname = u.lastname, registrationdate = u.registrationdate.value.addhours(-5) }; of course, linq2ef cannot convert " addhours " canonical function. there way this? update: another thought, if timezone offset stored in database column, there way have db perform calculation (date + offset)? linq entities supports sqlfunctions. if know offset number of hours this: var users = u in this.context.users select new userwithcorrecteddate { id = u.id, firstname = u.firstname, lastname = u.lastname, registrationdate = sqlfunctions.dat...

gdi+ - WxWidgets draw a bitmap with opacity -

-
how can draw wximage, or wxbitmap dc opacity? looks not possible standard dc or wxgraphicscontext. beginlayer/endlayer not yet implemented in wxgraphicscontext have been 1 solution. gdi+ doesn't seem support layers, non-trivial add this. the solution seems to programmatically alter alpha channel pixel-by-pixel? void yourcustomwindow::onpaint( wxpaintevent& event ) { wxpaintdc dc(this); wximage image( width, height ); image.initalpha(); unsigned char* imgdata = img.getdata(); unsigned char* imgalpha = img.getalpha(); // manipulate raw memory buffers populate // them whatever image like. // putting zeros everywhere create // transparent image. // done, not quite... // wxdc can draw wxbitmaps, not wximage, // 1 last step required // wxbitmap bmp( image ); dc.drawbitmap( bmp, 0, 0 ); }
