Implements Pix (image) class - the fundamental one for this library.
The pixN.c {N = 1,2,3,4,5} files are sorted by the type of operation.
The primary functions in these files are:
pix1.c: constructors, destructors and field accessors
pix2.c: pixel poking of image, pad and border pixels
pix3.c: masking and logical ops, counting, mirrored tiling
pix4.c: histograms, statistics, fg/bg estimation
pix5.c: property measurements, rectangle extraction

Important notes on direct management of pix image data
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Custom allocator and deallocator
--------------------------------
At the lowest level, you can specify the function that does the
allocation and deallocation of the data field in the pix.
By default, this is malloc and free. However, by calling
setPixMemoryManager(), custom functions can be substituted.
When using this, keep two things in mind:
(1) Call setPixMemoryManager() before any pix have been allocated
(2) Destroy all pix as usual, in order to prevent leaks.
In pixalloc.c, we provide an example custom allocator and deallocator.
To use it, you must call pmsCreate() before any pix have been allocated
and pmsDestroy() at the end after all pix have been destroyed.
Direct manipulation of the pix data field
-----------------------------------------
Memory management of the (image) data field in the pix is
handled differently from that in the colormap or text fields.
For colormap and text, the functions pixSetColormap() and
pixSetText() remove the existing heap data and insert the
new data. For the image data, pixSetData() just reassigns the
data field; any existing data will be lost if there isn't
another handle for it.
Why is pixSetData() limited in this way? Because the image
data can be very large, we need flexible ways to handle it,
particularly when you want to re-use the data in a different
context without making a copy. Here are some different
things you might want to do:
(1) Use pixCopy(pixd, pixs) where pixd is not the same size
as pixs. This will remove the data in pixd, allocate a
new data field in pixd, and copy the data from pixs, leaving
pixs unchanged.
(2) Use pixTransferAllData(pixd, &pixs, ...) to transfer the
data from pixs to pixd without making a copy of it. If
pixs is not cloned, this will do the transfer and destroy pixs.
But if the refcount of pixs is greater than 1, it just copies
the data and decrements the ref count.
(3) Use pixExtractData() to extract the image data from the pix
without copying if possible. This could be used, for example,
to convert from a pix to some other data structure with minimal
heap allocation. After the data is extracated, the pixels can
be munged and used in another context. However, the danger
here is that the pix might have a refcount > 1, in which case
a copy of the data must be made and the input pix left unchanged.
If there are no clones, the image data can be extracted without
a copy, and the data ptr in the pix must be nulled before
destroying it because the pix will no longer 'own' the data.
We have provided accessors and functions here that should be
sufficient so that you can do anything you want without
explicitly referencing any of the pix member fields.
However, to avoid memory smashes and leaks when doing special operations
on the pix data field, look carefully at the behavior of the image
data accessors and keep in mind that when you invoke pixDestroy(),
the pix considers itself the owner of all its heap data.

Input: pix Return: same pix (ptr), or null on error
Notes: (1) A "clone" is simply a handle (ptr) to an existing pix. It is implemented because (a) images can be large and hence expensive to copy, and (b) extra handles to a data structure need to be made with a simple policy to avoid both double frees and memory leaks. Pix are reference counted. The side effect of pixClone() is an increase by 1 in the ref count. (2) The protocol to be used is: (a) Whenever you want a new handle to an existing image, call pixClone(), which just bumps a ref count. (b) Always call pixDestroy() on all handles. This decrements the ref count, nulls the handle, and only destroys the pix when pixDestroy() has been called on all handles.

Input: pixd (<optional>; can be null, or equal to pixs, or different from pixs) pixs Return: pixd, or null on error
Notes: (1) There are three cases: (a) pixd == null (makes a new pix; refcount = 1) (b) pixd == pixs (no-op) (c) pixd != pixs (data copy; no change in refcount) If the refcount of pixd > 1, case (c) will side-effect these handles. (2) The general pattern of use is: pixd = pixCopy(pixd, pixs); This will work for all three cases. For clarity when the case is known, you can use: (a) pixd = pixCopy(NULL, pixs); (c) pixCopy(pixd, pixs); (3) For case (c), we check if pixs and pixd are the same size (w,h,d). If so, the data is copied directly. Otherwise, the data is reallocated to the correct size and the copy proceeds. The refcount of pixd is unchanged. (4) This operation, like all others that may involve a pre-existing pixd, will side-effect any existing clones of pixd.

Input: pixd (must be different from pixs) &pixs (will be nulled if refcount goes to 0) copytext (1 to copy the text field; 0 to skip) copyformat (1 to copy the informat field; 0 to skip) Return: 0 if OK, 1 on error
Notes: (1) This does a complete data transfer from pixs to pixd, followed by the destruction of pixs (refcount permitting). (2) If the refcount of pixs is 1, pixs is destroyed. Otherwise, the data in pixs is copied (rather than transferred) to pixd. (3) This operation, like all others with a pre-existing pixd, will side-effect any existing clones of pixd. The pixd refcount does not change. (4) When might you use this? Suppose you have an in-place Pix function (returning void) with the typical signature: void function-inplace(PIX *pix, ...) where "..." are non-pointer input parameters, and suppose further that you sometimes want to return an arbitrary Pix in place of the input Pix. There are two ways you can do this: (a) The straightforward way is to change the function signature to take the address of the Pix ptr: void function-inplace(PIX **ppix, ...) { PIX *pixt = function-makenew(*ppix); pixDestroy(ppix); *ppix = pixt; return; } Here, the input and returned pix are different, as viewed by the calling function, and the inplace function is expected to destroy the input pix to avoid a memory leak. (b) Keep the signature the same and use pixTransferAllData() to return the new Pix in the input Pix struct: void function-inplace(PIX *pix, ...) { PIX *pixt = function-makenew(pix); pixTransferAllData(pix, &pixt, 0, 0); // pixDestroy() is called on pixt return; } Here, the input and returned pix are the same, as viewed by the calling function, and the inplace function must never destroy the input pix, because the calling function maintains an unchanged handle to it.

Notes: (1) Unlike with the pix data field, pixSetColormap() destroys any existing colormap before assigning the new one. Because colormaps are not ref counted, it is important that the new colormap does not belong to any other pix.

Notes: (1) This extracts the pix image data for use in another context. The caller still needs to use pixDestroy() on the input pix. (2) If refcount == 1, the data is extracted and the pix->data ptr is set to NULL. (3) If refcount > 1, this simply returns a copy of the data, using the pix allocator, and leaving the input pix unchanged.

Notes: (1) This frees the data and sets the pix data ptr to null. It should be used before pixSetData() in the situation where you want to free any existing data before doing a subsequent assignment with pixSetData().

Input: pix &size (<optional return>=""> array size, which is the pix height) Return: array of line ptrs, or null on error
Notes: (1) This is intended to be used for fast random pixel access. For example, for an 8 bpp image, val = GET_DATA_BYTE(lines8[i], j); is equivalent to, but much faster than, pixGetPixel(pix, j, i, &val); (2) How much faster? For 1 bpp, it's from 6 to 10x faster. For 8 bpp, it's an amazing 30x faster. So if you are doing random access over a substantial part of the image, use this line ptr array. (3) When random access is used in conjunction with a stack, queue or heap, the overall computation time depends on the operations performed on each struct that is popped or pushed, and whether we are using a priority queue (O(logn)) or a queue or stack (O(1)). For example, for maze search, the overall ratio of time for line ptrs vs. pixGet/Set* is Maze type Type Time ratio binary queue 0.4 gray heap (priority queue) 0.6 (4) Because this returns a void** and the accessors take void*, the compiler cannot check the pointer types. It is strongly recommended that you adopt a naming scheme for the returned ptr arrays that indicates the pixel depth. (This follows the original intent of Simonyi's "Hungarian" application notation, where naming is used proactively to make errors visibly obvious.) By doing this, you can tell by inspection if the correct accessor is used. For example, for an 8 bpp pixg: void **lineg8 = pixGetLinePtrs(pixg, NULL); val = GET_DATA_BYTE(lineg8[i], j); // fast access; BYTE, 8 ... FREE(lineg8); // don't forget this (5) These are convenient for accessing bytes sequentially in an 8 bpp grayscale image. People who write image processing code on 8 bpp images are accustomed to grabbing pixels directly out of the raster array. Note that for little endians, you first need to reverse the byte order in each 32-bit word. Here's a typical usage pattern: pixEndianByteSwap(pix); // always safe; no-op on big-endians l_uint8 **lineptrs = (l_uint8 **)pixGetLinePtrs(pix, NULL); pixGetDimensions(pix, &w, &h, NULL); for (i = 0; i < h; i++) { l_uint8 *line = lineptrs[i]; for (j = 0; j < w; j++) { val = line[j]; ... } } pixEndianByteSwap(pix); // restore big-endian order FREE(lineptrs); This can be done even more simply as follows: l_uint8 **lineptrs = pixSetupByteProcessing(pix, &w, &h); for (i = 0; i < h; i++) { l_uint8 *line = lineptrs[i]; for (j = 0; j < w; j++) { val = line[j]; ... } } pixCleanupByteProcessing(pix, lineptrs);
