252	src = filename of source image
253	new = create new image, not thumbnail of existing image.
254	Requires "w" and "h" parameters set.
255	[ex: &new=FF0000\|75] - red background, 75% opacity
256	Set to hex color string of background. Opacity is
257	optional (defaults to 100% opaque).
258	w = max width of output thumbnail in pixels
259	h = max height of output thumbnail in pixels
260	wp = max width for portrait images
261	hp = max height for portrait images
262	wl = max width for landscape images
263	hl = max height for landscape images
264	ws = max width for square images
265	hs = max height for square images
266	f = output image format ("jpeg", "png", or "gif")
267	q = JPEG compression (1=worst, 95=best, 75=default)
268	sx = left side of source rectangle (default = 0)
269	(values 0 < sx < 1 represent percentage)
270	sy = top side of source rectangle (default = 0)
271	(values 0 < sy < 1 represent percentage)
272	sw = width of source rectangle (default = fullwidth)
273	(values 0 < sw < 1 represent percentage)
274	sh = height of source rectangle (default = fullheight)
275	(values 0 < sh < 1 represent percentage)
276	zc = zoom-crop. Will auto-crop off the larger dimension
277	so that the image will fill the smaller dimension
278	(requires both "w" and "h", overrides "iar", "far")
279	Set to "1" or "C" to zoom-crop towards the center,
280	or set to "T", "B", "L", "R", "TL", "TR", "BL", "BR"
281	to gravitate towards top/left/bottom/right directions
282	(requies ImageMagick for values other than "C" or "1")
283	bg = background hex color (default = FFFFFF)
284	bc = border hex color (default = 000000)
285	fltr = filter system. Call as an array as follows:
286	- "brit" (Brightness) [ex: &fltr[]=brit\|<value]
287	where <value is the amount +/- to adjust brightness
288	(range -255 to 255)
289	Availble in PHP5 with bundled GD only.
290	- "cont" (Constrast) [ex: &fltr[]=cont\|<value>]
291	where <value is the amount +/- to adjust contrast
292	(range -255 to 255)
293	Availble in PHP5 with bundled GD only.
294	- "gam" (Gamma Correction) [ex:
295	&fltr[]=gam\|<value>]
296	where <value> can be a number >0 to 10+ (default 1.0)
297	Must be >0 (zero gives no effect). There is no max,
298	although beyond 10 is pretty useless. Negative
299	numbers actually do something, maybe not quite the
300	desired effect, but interesting nonetheless.
301	- "sat" (SATuration) [ex: &fltr[]=sat\|<value>]
302	where <value> is a number between zero (no change)
303	and -100 (complete desaturation = grayscale), or it
304	can be any positive number for increased saturation.
305	- "ds" (DeSaturate) [ex: &fltr[]=ds\|<value>]
306	is an alias for "sat" except values are inverted
307	(positive values remove color, negative values boost
308	saturation)
309	- "gray" (Grayscale) [ex: &fltr[]=gray]
310	remove all color from image, make it grayscale
311	- "th" (Threshold) [ex: &fltr[]=th\|<value>]
312	makes image greyscale, then sets all pixels brighter
313	than <value> (range 0-255) to white, and all pixels
314	darker than <value> to black
315	- "rcd" (Reduce Color Depth) [ex:
316	&fltr[]=rcd\|<c>\|<d>]
317	where <c> is the number of colors (2-256) you want
318	in the output image, and <d> is "1" for dithering
319	(deault) or "0" for no dithering
320	- "clr" (Colorize) [ex:
321	&fltr[]=clr\|<value>\|<color>]
322	where <value> is a number between 0 and 100 for the
323	amount of colorization, and <color> is the hex color
324	to colorize to.
325	- "sep" (Sepia) [ex:
326	&fltr[]=sep\|<value>\|<color>]
327	where <value> is a number between 0 and 100 for the
328	amount of colorization (default=50), and <color> is
329	the hex color to colorize to (default=A28065).
330	Note: this behaves differently when applied by
331	ImageMagick, in which case 80 is default, and lower
332	values give brighter/yellower images and higher
333	values give darker/bluer images
334	- "usm" (UnSharpMask) [ex:
335	&fltr[]=usm\|<a>\|<r>\|<t>]
336	where <a> is the amount (default = 80), <r> is the
337	radius (default = 0.5), <t> is the threshold
338	(default = 3).
339	- "blur" (Blur) [ex: &fltr[]=blur\|<radius>]
340	where (0 < <radius> < 25) (default = 1)
341	- "gblr" (Gaussian Blur) [ex: &fltr[]=gblr]
342	Availble in PHP5 with bundled GD only.
343	- "sblr" (Selective Blur) [ex: &fltr[]=gblr]
344	Availble in PHP5 with bundled GD only.
345	- "smth" (Smooth) [ex: &fltr[]=smth\|<value>]
346	where <value> is the weighting value for the matrix
347	(range -10 to 10, default 6)
348	Availble in PHP5 with bundled GD only.
349	- "lvl" (Levels)
350	[ex: &fltr[]=lvl\|<channel>\|<method>\|<threshol>d
351	where <channel> can be one of "r", "g", "b", "a" (for
352	Red, Green, Blue, Alpha respectively), or "*" for all
353	RGB channels (default) based on grayscale average.
354	ImageMagick methods can support multiple channels
355	(eg "lvl\|rg\|3") but internal methods cannot (they will
356	use first character of channel string as channel)
357	<method> can be one of:
358	0=Internal RGB;
359	1=Internal Grayscale;
360	2=ImageMagick Contrast-Stretch (default)
361	3=ImageMagick Normalize (may appear over-saturated)
362	<threshold> is how much of brightest/darkest pixels
363	will be clipped in percent (default = 0.1%)
364	Using default parameters (&fltr[]=lvl) is similar to
365	Auto Contrast in Adobe Photoshop.
366	- "wb" (White Balance) [ex: &fltr[]=wb\|<c>]
367	where <c> is the target hex color to white balance
368	on, this color is what "should be" white, or light
369	gray. The filter attempts to maintain brightness so
370	any gray color can theoretically be used. If <c> is
371	omitted the filter guesses based on brightest pixels
372	in each of RGB
373	OR <c> can be the percent of white clipping used
374	to calculate auto-white-balance (default = 0.1%)
375	NOTE: "wb" in default settings already gives an effect
376	similar to "lvl", there is usually no need to use "lvl"
377	if "wb" is already used.
378	- "hist" (Histogram)
379	[ex: &fltr[]=hist\|<b>\|<c>\|<w>\|<h>\|<a>\|<o>\|<x>\|<y>]
380	Where <b> is the color band(s) to display, from back
381	to front (one or more of "rgba*" for Red Green Blue
382	Alpha and Grayscale respectively);
383	<c> is a semicolon-seperated list of hex colors to
384	use for each graph band (defaults to FF0000, 00FF00,
385	0000FF, 999999, FFFFFF respectively);
386	<w> and <h> are the width and height of the overlaid
387	histogram in pixels, or if <= 1 then percentage of
388	source image width/height;
389	<a> is the alignment (same as for "wmi" and "wmt");
390	<o> is opacity from 0 (transparent) to 100 (opaque)
391	(requires PHP v4.3.2, otherwise 100% opaque);
392	<x> and <y> are the edge margin in pixels (or percent
393	if 0 < (x\|y) < 1)
394	- "over" (OVERlay/underlay image) overlays an image on
395	the thumbnail, or overlays the thumbnail on another
396	image (to create a picture frame for example)
397	[ex: &fltr[]=over\|<i>\|<u>\|<m>\|<o>]
398	where <i> is the image filename; <u> is "0" (default)
399	for overlay the image on top of the thumbnail or "1"
400	for overlay the thumbnail on top of the image; <m> is
401	the margin - can be absolute pixels, or if < 1 is a
402	percentage of the thumbnail size [must be < 0.5]
403	(default is 0 for overlay and 10% for underlay);
404	<o> is opacity (0 = transparent, 100 = opaque)
405	(requires PHP v4.3.2, otherwise 100% opaque);
406	(thanks raynerapeï¿œgmailcom, shabazz3ï¿œmsuedu)
407	- "wmi" (WaterMarkImage)
408	[ex: &fltr[]=wmi\|<f>\|<a>\|<o>\|<x>\|<y>\|<r>] where
409	<f> is the filename of the image to overlay;
410	<a> is the alignment (one of BR, BL, TR, TL, C,
411	R, L, T, B, *) where B=bottom, T=top, L=left,
412	R=right, C=centre, *=tile)
413	or
414	an absolute position in pixels (from top-left
415	corner of canvas to top-left corner of overlay)
416	in format {xoffset}x{yoffset} (eg: "10x20")
417	note: this is center position of image if <>x
418	and <y> are set
419	<o> is opacity from 0 (transparent) to 100 (opaque)
420	(requires PHP v4.3.2, otherwise 100% opaque);
421	<x> and <y> are the edge (and inter-tile) margin in
422	pixels (or percent if 0 < (x\|y) < 1)
423	or
424	if <a> is absolute-position format then <x> and
425	<y> represent maximum width and height that the
426	watermark image will be scaled to fit inside
427	<r> is rotation angle of overlaid watermark
428	- "wmt" (WaterMarkText)
429	[ex: &fltr[]=wmt\|<t>\|<s>\|<a>\|<c>\|<f>\|<o>\|<m>\|<n>\|<b>\|<O>\|<x>]
430	where:
431	<t> is the text to use as a watermark;
432	URLencoded Unicode HTMLentities must be used for
433	characters beyond chr(127). For example, the
434	"eighth note" character (U+266A) is represented
435	as "♪" and then urlencoded to "%26%239834%3B"
436	Any instance of metacharacters will be replaced
437	with their calculated value. Currently supported:
438	^Fb = source image filesize in bytes
439	^Fk = source image filesize in kilobytes
440	^Fm = source image filesize in megabytes
441	^X = source image width in pixels
442	^Y = source image height in pixels
443	^x = thumbnail width in pixels
444	^y = thumbnail height in pixels
445	^^ = the character ^
446	<s> is the font size (1-5 for built-in font, or point
447	size for TrueType fonts);
448	<a> is the alignment (one of BR, BL, TR, TL, C, R, L,
449	T, B, * where B=bottom, T=top, L=left, R=right,
450	C=centre, *=tile);
451	or
452	an absolute position in pixels (from top-left
453	corner of canvas to top-left corner of overlay)
454	in format {xoffset}x{yoffset} (eg: "10x20")
455	<c> is the hex color of the text;
456	<f> is the filename of the TTF file (optional, if
457	omitted a built-in font will be used);
458	<o> is opacity from 0 (transparent) to 100 (opaque)
459	(requires PHP v4.3.2, otherwise 100% opaque);
460	<m> is the edge (and inter-tile) margin in percent;
461	<n> is the angle
462	<b> is the hex color of the background;
463	<O> is background opacity from 0 (transparent) to
464	100 (opaque)
465	(requires PHP v4.3.2, otherwise 100% opaque);
466	<x> is the direction(s) in which the background is
467	extended (either "x" or "y" (or both, but both
468	will obscure entire image))
469	Note: works with TTF fonts only, not built-in
470	- "flip" [ex: &fltr[]=flip\|x or &fltr[]=flip\|y]
471	flip image on X or Y axis
472	- "ric" [ex: &fltr[]=ric\|<x>\|<y>]
473	rounds off the corners of the image (to transparent
474	for PNG output), where <x> is the horizontal radius
475	of the curve and <y> is the vertical radius
476	- "elip" [ex: &fltr[]=elip]
477	similar to rounded corners but more extreme
478	- "mask" [ex: &fltr[]=mask\|filename.png]
479	greyscale values of mask are applied as the alpha
480	channel to the main image. White is opaque, black
481	is transparent.
482	- "bvl" (BeVeL) [ex:
483	&fltr[]=bvl\|<w>\|<c1>\|<c2>]
484	where <w> is the bevel width, <c1> is the hex color
485	for the top and left shading, <c2> is the hex color
486	for the bottom and right shading
487	- "bord" (BORDer) [ex:
488	&fltr[]=bord\|<w>\|<rx>\|<ry>\|<>c
489	where <w> is the width in pixels, <rx>
490	and <ry> are
491	horizontal and vertical radii for rounded corners,
492	and <c> is the hex color of the border
493	- "fram" (FRAMe) draws a frame, similar to "bord" but
494	more configurable
495	[ex: &fltr[]=fram\|<w1>\|<w2>\|<c1>\|<c2>\|<c3>]
496	where <w1> is the width of the main border,
497	<w2> is
498	the width of each side of the bevel part, <c1> is the
499	hex color of the main border, <c2> is the highlight
500	bevel color, <c3> is the shadow bevel color
501	- "drop" (DROP shadow)
502	[ex: &fltr[]=drop\|<d>\|<w>\|<clr>\|<a>]
503	where <d> is distance from image to shadow,
504	<w> is
505	width of shadow fade (not yet implemented),
506	<clr> is
507	the hex color of the shadow, and <a> is the angle of
508	the shadow (default=225)
509	- "crop" (CROP image)
510	[ex:
511	&fltr[]=crop\|<l>\|<r>\|<t>\|<b>]
512	where <l> is the number of pixels to crop from the left
513	side of the resized image; <r>, <t>,
514	<b> are for right,
515	top and bottom respectively. Where (0 < x < 1) the
516	value will be used as a percentage of width/height.
517	Left and top crops take precedence over right and
518	bottom values. Cropping will be limited such that at
519	least 1 pixel of width and height always remains.
520	- "rot" (ROTate)
521	[ex: &fltr[]=rot\|<a>\|<b>]
522	where <a> is the rotation angle in degrees;
523	<b> is the
524	background hex color. Similar to regular "ra" parameter
525	but is applied in filter order after regular processing
526	so you can rotate output of other filters.
527	- "size" (reSIZE)
528	[ex: &fltr[]=size\|<x>\|<y>\|<s>]
529	where <x> is the horizontal dimension in pixels,
530	<y> is
531	the vertical dimension in pixels, <s> is boolean whether
532	to stretch (if 1) or resize proportionately (0, default)
533	<x> and <y> will be interpreted as percentage of current
534	output image size if values are (0 < X < 1)
535	NOTE: do NOT use this filter unless absolutely neccesary.
536	It is only provided for cases where other filters need to
537	have absolute positioning based on source image and the
538	resultant image should be resized after other filters are
539	applied. This filter is less efficient than the standard
540	resizing procedures.
541	- "stc" (Source Transparent Color)
542	[ex: &fltr[]=stc\|<c>\|<n>\|<x>]
543	where <c> is the hex color of the target color to be made
544	transparent; <n> is the minimum threshold in percent (all
545	pixels within <n>% of the target color will be 100%
546	transparent, default <n>=5); <x> is the maximum threshold
547	in percent (all pixels more than <x>% from the target
548	color will be 100% opaque, default <x>=10); pixels between
549	the two thresholds will be partially transparent.
550	md5s = MD5 hash of the source image -- if this parameter is
551	passed with the hash of the source image then the
552	source image is not checked for existance or
553	modification and the cached file is used (if
554	available). If "md5s" is passed an empty string then
555	phpThumb.php dies and outputs the correct MD5 hash
556	value. This parameter is the single-file equivalent
557	of "cache_source_filemtime_ignore_*" configuration
558	paramters
559	xto = EXIF Thumbnail Only - set to only extract EXIF
560	thumbnail and not do any additional processing
561	ra = Rotate by Angle: angle of rotation in degrees
562	positive = counterclockwise, negative = clockwise
563	ar = Auto Rotate: set to "x" to use EXIF orientation
564	stored by camera. Can also be set to "l" or "L"
565	for landscape, or "p" or "P" for portrait. "l"
566	and "P" rotate the image clockwise, "L" and "p"
567	rotate the image counter-clockwise.
568	sfn = Source Frame Number - use this frame/page number for
569	multi-frame/multi-page source images (GIF, TIFF, etc)
570	aoe = Output Allow Enlarging - override the setting for
571	$CONFIG["output_allow_enlarging"] (1=on, 0=off)
572	("far" and "iar" both override this and allow output
573	larger than input)
574	iar = Ignore Aspect Ratio - disable proportional resizing
575	and stretch image to fit "h" & "w" (which must both
576	be set). (1=on, 0=off) (overrides "far")
577	far = Force Aspect Ratio - image will be created at size
578	specified by "w" and "h" (which must both be set).
579	Alignment: L=left,R=right,T=top,B=bottom,C=center
580	BL,BR,TL,TR use the appropriate direction if the
581	image is landscape or portrait.
582	dpi = Dots Per Inch - input DPI setting when importing from
583	vector image format such as PDF, WMF, etc
584	sia = Save Image As - default filename to save generated
585	image as. Specify the base filename, the extension
586	(eg: ".png") will be automatically added
587	maxb = MAXimum Byte size - output quality is auto-set to
588	fit thumbnail into "maxb" bytes (compression
589	quality is adjusted for JPEG, bit depth is adjusted
590	for PNG and GIF)
591	down = filename to save image to. If this is set the
592	browser will prompt to save to this filename rather
593	than display the image
594
595	';
