Or browse the 36 | [source code on GitHub][lxw_git]. 37 | 38 | [lxw_docs]: http://libxlsxwriter.github.io 39 | 40 | 41 | ## Building a Windows DLL of libxlsxwriter 42 | 43 | The MSVCLibXlsxWriter repository contains 3 directories: 44 | 45 | - **LibXlsxWriterProj**: A MSVC project to build a `LibXlsxWriter.dll` from 46 | the libxlsxwriter source code. The directory also contains a pre-built 47 | `Zlib.dll` file. 48 | 49 | - **ExampleExe**: A libxlsxwriter sample application built as a console 50 | application that requires the `LibXlsxWriter.dll` and `Zlib.dll` files. 51 | 52 | - **libxlsxwriter**: The libxlsxwriter source code in a git submodule, see 53 | below. 54 | 55 | The `libxlsxwriter` directory is a Git submodule. This means that it isn't 56 | included when you do a standard Git clone of MSVCLibXlsxWriter. In order to 57 | get the submodule as well as the project code you must clone the project 58 | recursively as follows: 59 | 60 | git clone --recursive https://github.com/jmcnamara/MSVCLibXlsxWriter.git 61 | 62 | Or update it explicitly as follows: 63 | 64 | git clone https://github.com/jmcnamara/MSVCLibXlsxWriter.git 65 | cd MSVCLibXlsxWriter/ 66 | git submodule init 67 | git submodule update 68 | 69 | This version of MSVCLibXlsxWriter contains libxlsxwriter version 0.3.8. 70 | 71 | 72 | 73 | To build the DLL of the library open the `LibXlsxWriterProj/LibXlsxWriter.sln` 74 | project in MS Visual Studio and build the solution using the "Build -> Build 75 | Solution" menu item. 76 | 77 | In the default configuration this will build an x64 debug LibXlsxWriter `.lib` 78 | and `.dll` in: 79 | 80 | MSVCLibXlsxWriter\LibXlsxWriterProj\x64\Debug 81 | 82 | 83 | ## Building a console application using the LibXlsxWriter.lib 84 | 85 | Ensure that `LibXlsxWriter.lib` was built correctly in the previous steps. 86 | 87 | To build the example executable open the `ExampleExe/ExampleExe.sln` project 88 | in MS Visual Studio and build the solution using the "Build -> Build Solution" 89 | menu item. 90 | 91 | In the default configuration this will build the following x64 exe file: 92 | 93 | MSVCLibXlsxWriter\ExampleExe\x64\Debug\ExampleExe.exe 94 | 95 | To run the application copy the `LibXlsxWriter.dll` and `Zlib.dll` files from 96 | the `MSVCLibXlsxWriter\LibXlsxWriterProj` sub-directories to the same 97 | directory as the executable. You can then run the application by double 98 | clicking on it in File Explorer or by opening a CMD console and running it 99 | from the directory. 100 | 101 | Once the program has run it will create a `chart_column.xlsx` file based on 102 | the default sample application in ExampleExe.cpp. You can run other 103 | libxlsxwriter example programs by copying the code from one of the 104 | `libxlsxwriter\example\*.c` programs. 105 | -------------------------------------------------------------------------------- /LibXlsxWriterProj/LibXlsxWriter/LibXlsxWriter.vcxproj.filters: -------------------------------------------------------------------------------- 1 | 2 | 3 | 4 | 5 | {93995380-89BD-4b04-88EB-625FBE52EBFB} 6 | h;hh;hpp;hxx;hm;inl;inc;xsd 7 | 8 | 9 | {4FC737F1-C7A5-4376-A066-2A32D752A2FF} 10 | cpp;c;cc;cxx;def;odl;idl;hpj;bat;asm;asmx 11 | 12 | 13 | 14 | 15 | Header Files 16 | 17 | 18 | Header Files 19 | 20 | 21 | Header Files 22 | 23 | 24 | Header Files 25 | 26 | 27 | Header Files 28 | 29 | 30 | Header Files 31 | 32 | 33 | Header Files 34 | 35 | 36 | Header Files 37 | 38 | 39 | 40 | 41 | Source Files 42 | 43 | 44 | Source Files 45 | 46 | 47 | Source Files 48 | 49 | 50 | Source Files 51 | 52 | 53 | Source Files 54 | 55 | 56 | Source Files 57 | 58 | 59 | Source Files 60 | 61 | 62 | Source Files 63 | 64 | 65 | Source Files 66 | 67 | 68 | Source Files 69 | 70 | 71 | Source Files 72 | 73 | 74 | Source Files 75 | 76 | 77 | Source Files 78 | 79 | 80 | Source Files 81 | 82 | 83 | Source Files 84 | 85 | 86 | Source Files 87 | 88 | 89 | Source Files 90 | 91 | 92 | Source Files 93 | 94 | 95 | Source Files 96 | 97 | 98 | Source Files 99 | 100 | 101 | Source Files 102 | 103 | 104 | Source Files 105 | 106 | 107 | Source Files 108 | 109 | 110 | Source Files 111 | 112 | 113 | 114 | 115 | Source Files 116 | 117 | 118 | 119 | 120 | 121 | -------------------------------------------------------------------------------- /ExampleExe/ExampleExe/ExampleExe.cpp: -------------------------------------------------------------------------------- 1 | // The example below is take from the libxlsxwriter/examples directory.

It may introduce 250 | some output latency (reading input without producing any output) except when 251 | forced to flush. 252 | 253 | The detailed semantics are as follows. deflate performs one or both of the 254 | following actions: 255 | 256 | - Compress more input starting at next_in and update next_in and avail_in 257 | accordingly. If not all input can be processed (because there is not 258 | enough room in the output buffer), next_in and avail_in are updated and 259 | processing will resume at this point for the next call of deflate(). 260 | 261 | - Provide more output starting at next_out and update next_out and avail_out 262 | accordingly. This action is forced if the parameter flush is non zero. 263 | Forcing flush frequently degrades the compression ratio, so this parameter 264 | should be set only when necessary (in interactive applications). Some 265 | output may be provided even if flush is not set. 266 | 267 | Before the call of deflate(), the application should ensure that at least 268 | one of the actions is possible, by providing more input and/or consuming more 269 | output, and updating avail_in or avail_out accordingly; avail_out should 270 | never be zero before the call. The application can consume the compressed 271 | output when it wants, for example when the output buffer is full (avail_out 272 | == 0), or after each call of deflate(). If deflate returns Z_OK and with 273 | zero avail_out, it must be called again after making room in the output 274 | buffer because there might be more output pending. 275 | 276 | Normally the parameter flush is set to Z_NO_FLUSH, which allows deflate to 277 | decide how much data to accumulate before producing output, in order to 278 | maximize compression. 279 | 280 | If the parameter flush is set to Z_SYNC_FLUSH, all pending output is 281 | flushed to the output buffer and the output is aligned on a byte boundary, so 282 | that the decompressor can get all input data available so far. (In 283 | particular avail_in is zero after the call if enough output space has been 284 | provided before the call.) Flushing may degrade compression for some 285 | compression algorithms and so it should be used only when necessary. This 286 | completes the current deflate block and follows it with an empty stored block 287 | that is three bits plus filler bits to the next byte, followed by four bytes 288 | (00 00 ff ff). 289 | 290 | If flush is set to Z_PARTIAL_FLUSH, all pending output is flushed to the 291 | output buffer, but the output is not aligned to a byte boundary. All of the 292 | input data so far will be available to the decompressor, as for Z_SYNC_FLUSH. 293 | This completes the current deflate block and follows it with an empty fixed 294 | codes block that is 10 bits long. This assures that enough bytes are output 295 | in order for the decompressor to finish the block before the empty fixed code 296 | block. 297 | 298 | If flush is set to Z_BLOCK, a deflate block is completed and emitted, as 299 | for Z_SYNC_FLUSH, but the output is not aligned on a byte boundary, and up to 300 | seven bits of the current block are held to be written as the next byte after 301 | the next deflate block is completed. In this case, the decompressor may not 302 | be provided enough bits at this point in order to complete decompression of 303 | the data provided so far to the compressor. It may need to wait for the next 304 | block to be emitted. This is for advanced applications that need to control 305 | the emission of deflate blocks. 306 | 307 | If flush is set to Z_FULL_FLUSH, all output is flushed as with 308 | Z_SYNC_FLUSH, and the compression state is reset so that decompression can 309 | restart from this point if previous compressed data has been damaged or if 310 | random access is desired. Using Z_FULL_FLUSH too often can seriously degrade 311 | compression. 312 | 313 | If deflate returns with avail_out == 0, this function must be called again 314 | with the same value of the flush parameter and more output space (updated 315 | avail_out), until the flush is complete (deflate returns with non-zero 316 | avail_out). In the case of a Z_FULL_FLUSH or Z_SYNC_FLUSH, make sure that 317 | avail_out is greater than six to avoid repeated flush markers due to 318 | avail_out == 0 on return. 319 | 320 | If the parameter flush is set to Z_FINISH, pending input is processed, 321 | pending output is flushed and deflate returns with Z_STREAM_END if there was 322 | enough output space; if deflate returns with Z_OK, this function must be 323 | called again with Z_FINISH and more output space (updated avail_out) but no 324 | more input data, until it returns with Z_STREAM_END or an error. After 325 | deflate has returned Z_STREAM_END, the only possible operations on the stream 326 | are deflateReset or deflateEnd. 327 | 328 | Z_FINISH can be used immediately after deflateInit if all the compression 329 | is to be done in a single step. In this case, avail_out must be at least the 330 | value returned by deflateBound (see below). Then deflate is guaranteed to 331 | return Z_STREAM_END.

Z_SYNC_FLUSH requests that inflate() flush as much 423 | output as possible to the output buffer. Z_BLOCK requests that inflate() 424 | stop if and when it gets to the next deflate block boundary. When decoding 425 | the zlib or gzip format, this will cause inflate() to return immediately 426 | after the header and before the first block. When doing a raw inflate, 427 | inflate() will go ahead and process the first block, and will return when it 428 | gets to the end of that block, or when it runs out of data. 429 | 430 | The Z_BLOCK option assists in appending to or combining deflate streams. 431 | Also to assist in this, on return inflate() will set strm->data_type to the 432 | number of unused bits in the last byte taken from strm->next_in, plus 64 if 433 | inflate() is currently decoding the last block in the deflate stream, plus 434 | 128 if inflate() returned immediately after decoding an end-of-block code or 435 | decoding the complete header up to just before the first byte of the deflate 436 | stream. The end-of-block will not be indicated until all of the uncompressed 437 | data from that block has been written to strm->next_out. The number of 438 | unused bits may in general be greater than seven, except when bit 7 of 439 | data_type is set, in which case the number of unused bits will be less than 440 | eight. data_type is set as noted here every time inflate() returns for all 441 | flush options, and so can be used to determine the amount of currently 442 | consumed input in bits. 443 | 444 | The Z_TREES option behaves as Z_BLOCK does, but it also returns when the 445 | end of each deflate block header is reached, before any actual data in that 446 | block is decoded. This allows the caller to determine the length of the 447 | deflate block header for later use in random access within a deflate block. 448 | 256 is added to the value of strm->data_type when inflate() returns 449 | immediately after reaching the end of the deflate block header. 450 | 451 | inflate() should normally be called until it returns Z_STREAM_END or an 452 | error. However if all decompression is to be performed in a single step (a 453 | single call of inflate), the parameter flush should be set to Z_FINISH. In 454 | this case all pending input is processed and all pending output is flushed; 455 | avail_out must be large enough to hold all of the uncompressed data for the 456 | operation to complete. (The size of the uncompressed data may have been 457 | saved by the compressor for this purpose.) The use of Z_FINISH is not 458 | required to perform an inflation in one step. However it may be used to 459 | inform inflate that a faster approach can be used for the single inflate() 460 | call. Z_FINISH also informs inflate to not maintain a sliding window if the 461 | stream completes, which reduces inflate's memory footprint. If the stream 462 | does not complete, either because not all of the stream is provided or not 463 | enough output space is provided, then a sliding window will be allocated and 464 | inflate() can be called again to continue the operation as if Z_NO_FLUSH had 465 | been used. 466 | 467 | In this implementation, inflate() always flushes as much output as 468 | possible to the output buffer, and always uses the faster approach on the 469 | first call. So the effects of the flush parameter in this implementation are 470 | on the return value of inflate() as noted below, when inflate() returns early 471 | when Z_BLOCK or Z_TREES is used, and when inflate() avoids the allocation of 472 | memory for a sliding window when Z_FINISH is used. 473 | 474 | If a preset dictionary is needed after this call (see inflateSetDictionary 475 | below), inflate sets strm->adler to the Adler-32 checksum of the dictionary 476 | chosen by the compressor and returns Z_NEED_DICT; otherwise it sets 477 | strm->adler to the Adler-32 checksum of all output produced so far (that is, 478 | total_out bytes) and returns Z_OK, Z_STREAM_END or an error code as described 479 | below. At the end of the stream, inflate() checks that its computed adler32 480 | checksum is equal to that saved by the compressor and returns Z_STREAM_END 481 | only if the checksum is correct. 482 | 483 | inflate() can decompress and check either zlib-wrapped or gzip-wrapped 484 | deflate data. The header type is detected automatically, if requested when 485 | initializing with inflateInit2(). Any information contained in the gzip 486 | header is not retained, so applications that need that information should 487 | instead use raw inflate, see inflateInit2() below, or inflateBack() and 488 | perform their own processing of the gzip header and trailer. When processing 489 | gzip-wrapped deflate data, strm->adler32 is set to the CRC-32 of the output 490 | producted so far. The CRC-32 is checked against the gzip trailer. 491 | 492 | inflate() returns Z_OK if some progress has been made (more input processed 493 | or more output produced), Z_STREAM_END if the end of the compressed data has 494 | been reached and all uncompressed output has been produced, Z_NEED_DICT if a 495 | preset dictionary is needed at this point, Z_DATA_ERROR if the input data was 496 | corrupted (input stream not conforming to the zlib format or incorrect check 497 | value), Z_STREAM_ERROR if the stream structure was inconsistent (for example 498 | next_in or next_out was Z_NULL), Z_MEM_ERROR if there was not enough memory, 499 | Z_BUF_ERROR if no progress is possible or if there was not enough room in the 500 | output buffer when Z_FINISH is used. Note that Z_BUF_ERROR is not fatal, and 501 | inflate() can be called again with more input and more output space to 502 | continue decompressing.

If a 556 | gzip stream is being written, strm->adler is a crc32 instead of an adler32. 557 | 558 | The memLevel parameter specifies how much memory should be allocated 559 | for the internal compression state. memLevel=1 uses minimum memory but is 560 | slow and reduces compression ratio; memLevel=9 uses maximum memory for 561 | optimal speed. The default value is 8. See zconf.h for total memory usage 562 | as a function of windowBits and memLevel. 563 | 564 | The strategy parameter is used to tune the compression algorithm.
