- * (this is the point: in order to avoid transgression of the Unisys patent
- * on the LZW algorithm.) However, miGIF generates data streams that any
- * reasonably sane LZW decompresser will decompress to what we want.
- *
- * miGIF compression uses run length encoding. It compresses horizontal runs
- * of pixels of the same color. This type of compression gives good results
- * on images with many runs, for example images with lines, text and solid
- * shapes on a solid-colored background. It gives little or no compression
- * on images with few runs, for example digital or scanned photos.

-/**
- * This method reconstructs image according to chosen interpolation method and then returns pixel (x,y).
- * (x,y) can lie between actual image pixels. If (x,y) lies outside of image, method returns value
- * according to overflow method.
- * This method is very useful for geometrical image transformations, where destination pixel
- * can often assume color value lying between source pixels.
- *
- * \param (x,y) - coordinates of pixel to return
- * GPCI method recreates "analogue" image back from digital data, so x and y
- * are float values and color value of point (1.1,1) will generally not be same
- * as (1,1). Center of first pixel is at (0,0) and center of pixel right to it is (1,0).
- * (0.5,0) is half way between these two pixels.
- * \param inMethod - interpolation (reconstruction) method (kernel) to use:
- * - IM_NEAREST_NEIGHBOUR - returns colour of nearest lying pixel (causes stairy look of
- * processed images)
- * - IM_BILINEAR - interpolates colour from four neighbouring pixels (softens image a bit)
- * - IM_BICUBIC - interpolates from 16 neighbouring pixels (can produce "halo" artifacts)
- * - IM_BICUBIC2 - interpolates from 16 neighbouring pixels (perhaps a bit less halo artifacts
- than IM_BICUBIC)
- * - IM_BSPLINE - interpolates from 16 neighbouring pixels (softens image, washes colours)
- * (As far as I know, image should be prefiltered for this method to give
- * good results... some other time :) )
- * This method uses bicubic interpolation kernel from CXImage 5.99a and older
- * versions.
- * - IM_LANCZOS - interpolates from 12*12 pixels (slow, ringing artifacts)
- *
- * \param ofMethod - overflow method (see comments at GetPixelColorWithOverflow)
- * \param rplColor - pointer to color used for out of borders pixels in OM_COLOR mode
- * (and other modes if colour can't calculated in a specified way)

- * If only one of both is more than 1, method uses combination of interpolation and averaging.
- * Chosen interpolation method is used, but since it is averaged later on, there is little difference
- * between IM_BILINEAR (perhaps best for this case) and better methods. IM_NEAREST_NEIGHBOUR again
- * leads to aliasing artifacts.
- * This method is a bit slower than GetPixelColorInterpolated and when aliasing is not a problem, you should
- * simply use the later.

- Note by Author:
-*********************************************************************
-
- Metafile Formats:
- =================
-
- There are 2 kinds of Windows Metafiles:
- - Standard Windows Metafile
- - Placeable Windows Metafile
-
- A StandardWindows Metafile looks like:
- - Metafile Header (MEATAHEADER)
- - Metafile Records
-
- A Placeable Metafile looks like:
- - Aldus Header (METAFILEHEADER)
- - Metafile Header (METAHEADER)
- - Metafile Records
-
- The "Metafile Header" and the "Metafile Records" are the same
- for both formats. However, the Standard Metafile does not contain any
- information about the original dimensions or x/y ratio of the Metafile.
-
- I decided, to allow only placeable Metafiles here. If you also want to
- enable Standard Metafiles, you will have to guess the dimensions of
- the image.
-

- Limitations: see ximawmf.h
- you may configure some stuff there

-*********************************************************************
-
- Limitations:
- ============
-
- a) Transparency:
-
- A Metafile is vector graphics, which has transparency by design.
- This class always converts into a Bitmap format. Transparency is
- supported, but there is no good way to find out, which parts
- of the Metafile are transparent. There are two ways how we can
- handle this:
-
- - Clear the Background of the Bitmap with the background color
- you like (i have used COLOR_WINDOW) and don't support transparency.
-
- below #define XMF_SUPPORT_TRANSPARENCY 0
- #define XMF_COLOR_BACK RGB(Background color you like)
-
- - Clear the Background of the Bitmap with a very unusual color
- (which one ?) and use this color as the transparent color
-
- below #define XMF_SUPPORT_TRANSPARENCY 1
- #define XMF_COLOR_TRANSPARENT_R ...
- #define XMF_COLOR_TRANSPARENT_G ...
- #define XMF_COLOR_TRANSPARENT_B ...
-
- b) Resolution
-
- Once we have converted the Metafile into a Bitmap and we zoom in
- or out, the image may not look very good. If we still had the
- original Metafile, zooming would produce good results always.
-
- c) Size
-
- Although the filesize of a Metafile may be very small, it might
- produce a Bitmap with a bombastic size. Assume you have a Metafile
- with an image size of 6000*4000, which contains just one Metafile
- record ((e.g. a line from (0,0) to (6000, 4000)). The filesize
- of this Metafile would be let's say 100kB. If we convert it to
- a 6000*4000 Bitmap with 24 Bits/Pixes, the Bitmap would consume
- about 68MB of memory.
-
- I have choosen, to limit the size of the Bitmap to max.
- screensize, to avoid memory problems.
-
- If you want something else,
- modify #define XMF_MAXSIZE_CX / XMF_MAXSIZE_CY below

The state machine is - structured roughly as follows: - - for (;;) switch (state) { - ... - case STATEn: - if (not enough input data or output space to make progress) - return; - ... make progress ... - state = STATEm; - break; - ... - } - - so when inflate() is called again, the same case is attempted again, and - if the appropriate resources are provided, the machine proceeds to the - next state. The NEEDBITS() macro is usually the way the state evaluates - whether it can proceed or should return. NEEDBITS() does the return if - the requested bits are not available. The typical use of the BITS macros - is: - - NEEDBITS(n); - ... do something with BITS(n) ... - DROPBITS(n); - - where NEEDBITS(n) either returns from inflate() if there isn't enough - input left to load n bits into the accumulator, or it continues. BITS(n) - gives the low n bits in the accumulator. When done, DROPBITS(n) drops - the low n bits off the accumulator. INITBITS() clears the accumulator - and sets the number of available bits to zero. BYTEBITS() discards just - enough bits to put the accumulator on a byte boundary. After BYTEBITS() - and a NEEDBITS(8), then BITS(8) would return the next byte in the stream. - - NEEDBITS(n) uses PULLBYTE() to get an available byte of input, or to return - if there is no input available. The decoding of variable length codes uses - PULLBYTE() directly in order to pull just enough bytes to decode the next - code, and no more. - - Some states loop until they get enough input, making sure that enough - state information is maintained to continue the loop where it left off - if NEEDBITS() returns in the loop. For example, want, need, and keep - would all have to actually be part of the saved state in case NEEDBITS() - returns: - - case STATEw: - while (want < need) { - NEEDBITS(n); - keep[want++] = BITS(n); - DROPBITS(n); - } - state = STATEx; - case STATEx: - - As shown above, if the next state is also the next case, then the break - is omitted. - - A state may also return if there is not enough output space available to - complete that state. Those states are copying stored data, writing a - literal byte, and copying a matching string. - - When returning, a "goto inf_leave" is used to update the total counters, - update the check value, and determine whether any progress has been made - during that inflate() call in order to return the proper return code. - Progress is defined as a change in either strm->avail_in or strm->avail_out. - When there is a window, goto inf_leave will update the window with the last - output written. If a goto inf_leave occurs in the middle of decompression - and there is no window currently, goto inf_leave will create one and copy - output to the window for the next call of inflate(). - - In this implementation, the flush parameter of inflate() only affects the - return code (per zlib.h). inflate() always writes as much as possible to - strm->next_out, given the space available and the provided input--the effect - documented in zlib.h of Z_SYNC_FLUSH. Furthermore, inflate() always defers - the allocation of and copying into a sliding window until necessary, which - provides the effect documented in zlib.h for Z_FINISH when the entire input - stream available. So the only thing the flush parameter actually does is: - when flush is set to Z_FINISH, inflate() cannot return Z_OK. Instead it - will return Z_BUF_ERROR if it has not reached the end of the stream. - */ - -int ZEXPORT inflate(strm, flush) -z_streamp strm; -int flush; -{ - struct inflate_state FAR *state; - unsigned char FAR *next; /* next input */ - unsigned char FAR *put; /* next output */ - unsigned have, left; /* available input and output */ - unsigned long hold; /* bit buffer */ - unsigned bits; /* bits in bit buffer */ - unsigned in, out; /* save starting available input and output */ - unsigned copy; /* number of stored or match bytes to copy */ - unsigned char FAR *from; /* where to copy match bytes from */ - code here; /* current decoding table entry */ - code last; /* parent table entry */ - unsigned len; /* length to copy for repeats, bits to drop */ - int ret; /* return code */ -#ifdef GUNZIP - unsigned char hbuf[4]; /* buffer for gzip header crc calculation */ -#endif - static const unsigned short order[19] = /* permutation of code lengths */ - {16, 17, 18, 0, 8, 7, 9, 6, 10, 5, 11, 4, 12, 3, 13, 2, 14, 1, 15}; - - if (strm == Z_NULL || strm->state == Z_NULL || strm->next_out == Z_NULL || - (strm->next_in == Z_NULL && strm->avail_in != 0)) - return Z_STREAM_ERROR; - - state = (struct inflate_state FAR *)strm->state; - if (state->mode == TYPE) state->mode = TYPEDO; /* skip check */ - LOAD(); - in = have; - out = left; - ret = Z_OK; - for (;;) - switch (state->mode) { - case HEAD: - if (state->wrap == 0) { - state->mode = TYPEDO; - break; - } - NEEDBITS(16); -#ifdef GUNZIP - if ((state->wrap & 2) && hold == 0x8b1f) { /* gzip header */ - state->check = crc32(0L, Z_NULL, 0); - CRC2(state->check, hold); - INITBITS(); - state->mode = FLAGS; - break; - } - state->flags = 0; /* expect zlib header */ - if (state->head != Z_NULL) - state->head->done = -1; - if (!(state->wrap & 1) || /* check if zlib header allowed */ -#else - if ( -#endif - ((BITS(8) << 8) + (hold >> 8)) % 31) { - strm->msg = (char *)"incorrect header check"; - state->mode = BAD; - break; - } - if (BITS(4) != Z_DEFLATED) { - strm->msg = (char *)"unknown compression method"; - state->mode = BAD; - break; - } - DROPBITS(4); - len = BITS(4) + 8; - if (state->wbits == 0) - state->wbits = len; - else if (len > state->wbits) { - strm->msg = (char *)"invalid window size"; - state->mode = BAD; - break; - } - state->dmax = 1U << len; - Tracev((stderr, "inflate: zlib header ok\n")); - strm->adler = state->check = adler32(0L, Z_NULL, 0); - state->mode = hold & 0x200 ?

In this case, the decompressor may not - be provided enough bits at this point in order to complete decompression of - the data provided so far to the compressor. It may need to wait for the next - block to be emitted. This is for advanced applications that need to control - the emission of deflate blocks. - - If flush is set to Z_FULL_FLUSH, all output is flushed as with - Z_SYNC_FLUSH, and the compression state is reset so that decompression can - restart from this point if previous compressed data has been damaged or if - random access is desired.

When decoding - the zlib or gzip format, this will cause inflate() to return immediately - after the header and before the first block. When doing a raw inflate, - inflate() will go ahead and process the first block, and will return when it - gets to the end of that block, or when it runs out of data. - - The Z_BLOCK option assists in appending to or combining deflate streams. - Also to assist in this, on return inflate() will set strm->data_type to the - number of unused bits in the last byte taken from strm->next_in, plus 64 if - inflate() is currently decoding the last block in the deflate stream, plus - 128 if inflate() returned immediately after decoding an end-of-block code or - decoding the complete header up to just before the first byte of the deflate - stream. The end-of-block will not be indicated until all of the uncompressed - data from that block has been written to strm->next_out. The number of - unused bits may in general be greater than seven, except when bit 7 of - data_type is set, in which case the number of unused bits will be less than - eight. data_type is set as noted here every time inflate() returns for all - flush options, and so can be used to determine the amount of currently - consumed input in bits. - - The Z_TREES option behaves as Z_BLOCK does, but it also returns when the - end of each deflate block header is reached, before any actual data in that - block is decoded. This allows the caller to determine the length of the - deflate block header for later use in random access within a deflate block. - 256 is added to the value of strm->data_type when inflate() returns - immediately after reaching the end of the deflate block header. - - inflate() should normally be called until it returns Z_STREAM_END or an - error. However if all decompression is to be performed in a single step (a - single call of inflate), the parameter flush should be set to Z_FINISH. In - this case all pending input is processed and all pending output is flushed; - avail_out must be large enough to hold all the uncompressed data. (The size - of the uncompressed data may have been saved by the compressor for this - purpose.) The next operation on this stream must be inflateEnd to deallocate - the decompression state.

So the only effect of the flush parameter in this implementation - is on the return value of inflate(), as noted below, or when it returns early - because Z_BLOCK or Z_TREES is used. - - If a preset dictionary is needed after this call (see inflateSetDictionary - below), inflate sets strm->adler to the adler32 checksum of the dictionary - chosen by the compressor and returns Z_NEED_DICT; otherwise it sets - strm->adler to the adler32 checksum of all output produced so far (that is, - total_out bytes) and returns Z_OK, Z_STREAM_END or an error code as described - below.
