Wil je een plaatje dat wij hebben geupload gebruiken op het forum (Bijvoorbeeld een logo van een game, of cover-art, of een ingame plaatje) dan kan je dat via de zogenaamde Thumbs doen. We nemen als voorbeeld dit plaatje van The Order: 1886:

Code:
http://www.gamed.nl/messages/196294.jpg


Dit plaatje is echter veel te groot om op het forum te gebruiken. Daarom kan je zogenoemde Thumbs gebruiken. De Thumb versie wordt automatisch aangemaakt als je ''messages'' vervangt door ''thumb'', zoals hier:

Code:
http://www.gamed.nl/thumb/196294.jpg


Wat dit als resultaat geeft:


Je kan hier de breedte van aanpassen. Let op: Thumbs worden alleen verkleind, niet vergroot. Door de breedte aan te passen naar iets groters verlies je dus aan kwaliteit. Hier is de code om de breedte aan te passen:

Code:
http://www.gamed.nl/thumb/196294.jpg/w=720


En dat geeft als resultaat:


Filters zijn ook aanwezig, zoals spiegelen, blur, sepia, en meer. Dit gaat iets anders te werk (vooralsnog) dan simpelweg de bestaande thumb nemen en dan de code voor het filter aan te passen. Aangezien een Thumb standaard 500 pixels is zal je, als een filter wilt gebruiken, altijd moeten beginnen met dit:

Code:
http://www.gamed.nl/thumb/196294.jpg/w=500


Het probleem is namelijk dat als je ''messages'' wijzigt naar ''thumb'' deze automatisch wordt verkleint naar 500 pixels, maar je daarna geen filter meer toe kan voegen. Voeg je wel een filter toe zonder bovenstaande code, dan krijg het origineel met het filter erbovenop. Ook is het zo dat je de plaatjes met filter niet als plaatje kan toevoegen (vooralsnog) in je reactie. Als dit in de toekomst wordt veranderd, dan zal dit artikel erop aangepast worden.

Nu dit bekend is, kan je lekker klooien met filters. Hieronder de resultaten van:

Blur:
Code:
http://www.gamed.nl/thumb/196294.jpg/w=500&fltr[]=blur


Sepia:
Code:
http://www.gamed.nl/thumb/196294.jpg/w=500&fltr[]=sep


Zwart/wit:
Code:
http://www.gamed.nl/thumb/196294.jpg/w=500&fltr[]=gray


Gespiegeld:
Code:
http://www.gamed.nl/thumb/196294.jpg/w=500&fltr[]=flip|x


Een combinatie:
Code:
http://www.gamed.nl/thumb/196294.jpg/w=500&fltr[]=flip|x&fltr[]=sep


Meervoudige combinatie:
Code:
http://www.gamed.nl/thumb/196294.jpg/w=500&fltr[]=flip|x&fltr[]=sep&fltr[]=blur


Watermerk:
Code:

Meer parameters vind je hier: http://phpthumb.sourceforge.net/demo/docs/phpthumb.readme.txt of in de spoiler hieronder. Let op, het kan zijn dat sommige parameters niet zullen werken.

Spoiler: toon

===========
Parameters:
===========

src = filename of source image
new = create new image, not thumbnail of existing image.
Requires "w" and "h" parameters set.
[ex: &new=FF0000|75] - red background, 75% opacity
Set to hex color string of background. Opacity is
optional (defaults to 100% opaque).
w = max width of output thumbnail in pixels
h = max height of output thumbnail in pixels
wp = max width for portrait images
hp = max height for portrait images
wl = max width for landscape images
hl = max height for landscape images
ws = max width for square images
hs = max height for square images
f = output image format ("jpeg", "png", or "gif")
q = JPEG compression (1=worst, 95=best, 75=default)
sx = left side of source rectangle (default = 0)
(values 0 < sx < 1 represent percentage)
sy = top side of source rectangle (default = 0)
(values 0 < sy < 1 represent percentage)
sw = width of source rectangle (default = fullwidth)
(values 0 < sw < 1 represent percentage)
sh = height of source rectangle (default = fullheight)
(values 0 < sh < 1 represent percentage)
zc = zoom-crop. Will auto-crop off the larger dimension
so that the image will fill the smaller dimension
(requires both "w" and "h", overrides "iar", "far")
Set to "1" or "C" to zoom-crop towards the center,
or set to "T", "B", "L", "R", "TL", "TR", "BL", "BR"
to gravitate towards top/left/bottom/right directions
(requies ImageMagick for values other than "C" or "1")
bg = background hex color (default = FFFFFF)
bc = border hex color (default = 000000)
fltr = filter system. Call as an array as follows:
- "brit" (Brightness) [ex: &fltr[]=brit|<value>]
where <value> is the amount +/- to adjust brightness
(range -255 to 255)
Availble in PHP5 with bundled GD only.
- "cont" (Constrast) [ex: &fltr[]=cont|<value>]
where <value> is the amount +/- to adjust contrast
(range -255 to 255)
Availble in PHP5 with bundled GD only.
- "gam" (Gamma Correction) [ex: &fltr[]=gam|<value>]
where <value> can be a number 0.01 to 10 (default 1.0)
Must be >0 (zero gives no effect). There is no max,
although beyond 10 is pretty useless. Negative
numbers actually do something, maybe not quite the
desired effect, but interesting nonetheless.
- "sat" (SATuration) [ex: &fltr[]=sat|<value>]
where <value> is a number between zero (no change)
and -100 (complete desaturation = grayscale), or it
can be any positive number for increased saturation.
- "ds" (DeSaturate) [ex: &fltr[]=ds|<value>]
is an alias for "sat" except values are inverted
(positive values remove color, negative values boost
saturation)
- "gray" (Grayscale) [ex: &fltr[]=gray]
remove all color from image, make it grayscale
- "th" (Threshold) [ex: &fltr[]=th|<value>]
makes image greyscale, then sets all pixels brighter
than <value> (range 0-255) to white, and all pixels
darker than <value> to black
- "rcd" (Reduce Color Depth) [ex: &fltr[]=rcd|<c>|<d>]
where <c> is the number of colors (2-256) you want
in the output image, and <d> is "1" for dithering
(deault) or "0" for no dithering
- "clr" (Colorize) [ex: &fltr[]=clr|<value>|<color>]
where <value> is a number between 0 and 100 for the
amount of colorization, and <color> is the hex color
to colorize to.
- "sep" (Sepia) [ex: &fltr[]=sep|<value>|<color>]
where <value> is a number between 0 and 100 for the
amount of colorization (default=50), and <color> is
the hex color to colorize to (default=A28065).
Note: this behaves differently when applied by
ImageMagick, in which case 80 is default, and lower
values give brighter/yellower images and higher
values give darker/bluer images
- "usm" (UnSharpMask) [ex: &fltr[]=usm|<a>|<r>|<t>]
where <a> is the amount (default = 80, range 0-255),
<r> is the radius (default = 0.5, range 0.0-10.0),
<t> is the threshold (default = 3, range 0-50).
- "blur" (Blur) [ex: &fltr[]=blur|<radius>]
where (0 < <radius> < 25) (default = 1)
- "gblr" (Gaussian Blur) [ex: &fltr[]=gblr]
Availble in PHP5 with bundled GD only.
- "sblr" (Selective Blur) [ex: &fltr[]=gblr]
Availble in PHP5 with bundled GD only.
- "smth" (Smooth) [ex: &fltr[]=smth|<value>]
where <value> is the weighting value for the matrix
(range -10 to 10, default 6)
Availble in PHP5 with bundled GD only.
- "lvl" (Levels)
[ex: &fltr[]=lvl|<channel>|<method>|<threshold>
where <channel> can be one of 'r', 'g', 'b', 'a' (for
Red, Green, Blue, Alpha respectively), or '*' for all
RGB channels (default) based on grayscale average.
ImageMagick methods can support multiple channels
(eg "lvl|rg|3") but internal methods cannot (they will
use first character of channel string as channel)
<method> can be one of:
0=Internal RGB;
1=Internal Grayscale;
2=ImageMagick Contrast-Stretch (default)
3=ImageMagick Normalize (may appear over-saturated)
<threshold> is how much of brightest/darkest pixels
will be clipped in percent (default = 0.1%)
Using default parameters (&fltr[]=lvl) is similar to
Auto Contrast in Adobe Photoshop.
- "wb" (White Balance) [ex: &fltr[]=wb|<c>]
where <c> is the target hex color to white balance
on, this color is what "should be" white, or light
gray. The filter attempts to maintain brightness so
any gray color can theoretically be used. If <c> is
omitted the filter guesses based on brightest pixels
in each of RGB
OR <c> can be the percent of white clipping used
to calculate auto-white-balance (default = 0.1%)
NOTE: "wb" in default settings already gives an effect
similar to "lvl", there is usually no need to use "lvl"
if "wb" is already used.
- "hist" (Histogram)
[ex: &fltr[]=hist|<b>|<c>|<w>|<h>|<a>|<o>|<x>|<y>]
Where <b> is the color band(s) to display, from back
to front (one or more of "rgba*" for Red Green Blue
Alpha and Grayscale respectively);
<c> is a semicolon-seperated list of hex colors to
use for each graph band (defaults to FF0000, 00FF00,
0000FF, 999999, FFFFFF respectively);
<w> and <h> are the width and height of the overlaid
histogram in pixels, or if <= 1 then percentage of
source image width/height;
<a> is the alignment (same as for "wmi" and "wmt");
<o> is opacity from 0 (transparent) to 100 (opaque)
(requires PHP v4.3.2, otherwise 100% opaque);
<x> and <y> are the edge margin in pixels (or percent
if 0 < (x|y) < 1)
- "over" (OVERlay/underlay image) overlays an image on
the thumbnail, or overlays the thumbnail on another
image (to create a picture frame for example)
[ex: &fltr[]=over|<i>|<u>|<m>|<o>]
where <i> is the image filename; <u> is "0" (default)
for overlay the image on top of the thumbnail or "1"
for overlay the thumbnail on top of the image; <m> is
the margin - can be absolute pixels, or if < 1 is a
percentage of the thumbnail size [must be < 0.5]
(default is 0 for overlay and 10% for underlay);
<o> is opacity (0 = transparent, 100 = opaque)
(requires PHP v4.3.2, otherwise 100% opaque);
(thanks raynerapeØgmail*com, shabazz3Ømsu*edu)
- "wmi" (WaterMarkImage)
[ex: &fltr[]=wmi|<f>|<a>|<o>|<x>|<y>|<r>] where
<f> is the filename of the image to overlay;
<a> is the alignment (one of BR, BL, TR, TL, C,
R, L, T, B, *) where B=bottom, T=top, L=left,
R=right, C=centre, *=tile)
*or*
an absolute position in pixels (from top-left
corner of canvas to top-left corner of overlay)
in format {xoffset}x{yoffset} (eg: "10x20")
note: this is center position of image if <x>
and <y> are set
<o> is opacity from 0 (transparent) to 100 (opaque)
(requires PHP v4.3.2, otherwise 100% opaque);
<x> and <y> are the edge (and inter-tile) margin in
pixels (or percent if 0 < (x|y) < 1)
*or*
if <a> is absolute-position format then <x> and
<y> represent maximum width and height that the
watermark image will be scaled to fit inside
<r> is rotation angle of overlaid watermark
- "wmt" (WaterMarkText)
[ex: &fltr[]=wmt|<t>|<s>|<a>|<c>|<f>|<o>|<m>|<n>|<b>|<O>|<x>]
where:
<t> is the text to use as a watermark;
URLencoded Unicode HTMLentities must be used for
characters beyond chr(127). For example, the
"eighth note" character (U+266A) is represented
as "♪" and then urlencoded to "%26%239834%3B"
Any instance of metacharacters will be replaced
with their calculated value. Currently supported:
^Fb = source image filesize in bytes
^Fk = source image filesize in kilobytes
^Fm = source image filesize in megabytes
^X = source image width in pixels
^Y = source image height in pixels
^x = thumbnail width in pixels
^y = thumbnail height in pixels
^^ = the character ^
<s> is the font size (1-5 for built-in font, or point
size for TrueType fonts);
<a> is the alignment (one of BR, BL, TR, TL, C, R, L,
T, B, * where B=bottom, T=top, L=left, R=right,
C=centre, *=tile);
note: * does not work for built-in font "wmt"
*or*
an absolute position in pixels (from top-left
corner of canvas to top-left corner of overlay)
in format {xoffset}x{yoffset} (eg: "10x20")
<c> is the hex color of the text;
<f> is the filename of the TTF file (optional, if
omitted a built-in font will be used);
<o> is opacity from 0 (transparent) to 100 (opaque)
(requires PHP v4.3.2, otherwise 100% opaque);
<m> is the edge (and inter-tile) margin in percent;
<n> is the angle
<b> is the hex color of the background;
<O> is background opacity from 0 (transparent) to
100 (opaque)
(requires PHP v4.3.2, otherwise 100% opaque);
<x> is the direction(s) in which the background is
extended (either 'x' or 'y' (or both, but both
will obscure entire image))
Note: works with TTF fonts only, not built-in
- "flip" [ex: &fltr[]=flip|x or &fltr[]=flip|y]
flip image on X or Y axis
- "ric" [ex: &fltr[]=ric|<x>|<y>]
rounds off the corners of the image (to transparent
for PNG output), where <x> is the horizontal radius
of the curve and <y> is the vertical radius
- "elip" [ex: &fltr[]=elip]
similar to rounded corners but more extreme
- "mask" [ex: &fltr[]=mask|filename.png|<i>]
greyscale values of mask are applied as the alpha
channel to the main image. White is opaque, black
is transparent, unless the <i> (invert) parameter is
set to 1 in which case black is opaque and white is
transparent
- "bvl" (BeVeL) [ex: &fltr[]=bvl|<w>|<c1>|<c2>]
where <w> is the bevel width, <c1> is the hex color
for the top and left shading, <c2> is the hex color
for the bottom and right shading
- "bord" (BORDer) [ex: &fltr[]=bord|<w>|<rx>|<ry>|<c>
where <w> is the width in pixels, <rx> and <ry> are
horizontal and vertical radii for rounded corners,
and <c> is the hex color of the border
- "fram" (FRAMe) draws a frame, similar to "bord" but
more configurable
[ex: &fltr[]=fram|<w1>|<w2>|<c1>|<c2>|<c3>]
where <w1> is the width of the main border, <w2> is
the width of each side of the bevel part, <c1> is the
hex color of the main border, <c2> is the highlight
bevel color, <c3> is the shadow bevel color
- "drop" (DROP shadow)
[ex: &fltr[]=drop|<d>|<w>|<clr>|<a>|<o>]
where <d> is distance from image to shadow, <w> is
width of shadow fade (not yet implemented), <clr> is
the hex color of the shadow, <a> is the angle of the
shadow (default=225), <o> is opacity (0=transparent,
100=opaque, default=100) (not yet implemented)
- "crop" (CROP image)
[ex: &fltr[]=crop|<l>|<r>|<t>|<b>]
where <l> is the number of pixels to crop from the left
side of the resized image; <r>, <t>, <b> are for right,
top and bottom respectively. Where (0 < x < 1) the
value will be used as a percentage of width/height.
Left and top crops take precedence over right and
bottom values. Cropping will be limited such that at
least 1 pixel of width and height always remains.
- "rot" (ROTate)
[ex: &fltr[]=rot|<a>|<b>]
where <a> is the rotation angle in degrees; <b> is the
background hex color. Similar to regular "ra" parameter
but is applied in filter order after regular processing
so you can rotate output of other filters.
- "size" (reSIZE)
[ex: &fltr[]=size|<x>|<y>|<s>]
where <x> is the horizontal dimension in pixels, <y> is
the vertical dimension in pixels, <s> is boolean whether
to stretch (if 1) or resize proportionately (0, default)
<x> and <y> will be interpreted as percentage of current
output image size if values are (0 < X < 1)
NOTE: do NOT use this filter unless absolutely neccesary.
It is only provided for cases where other filters need to
have absolute positioning based on source image and the
resultant image should be resized after other filters are
applied. This filter is less efficient than the standard
resizing procedures.
- "stc" (Source Transparent Color)
[ex: &fltr[]=stc|<c>|<n>|<x>]
where <c> is the hex color of the target color to be made
transparent; <n> is the minimum threshold in percent (all
pixels within <n>% of the target color will be 100%
transparent, default <n>=5); <x> is the maximum threshold
in percent (all pixels more than <x>% from the target
color will be 100% opaque, default <x>=10); pixels between
the two thresholds will be partially transparent.
md5s = MD5 hash of the source image -- if this parameter is
passed with the hash of the source image then the
source image is not checked for existance or
modification and the cached file is used (if
available). If 'md5s' is passed an empty string then
phpThumb.php dies and outputs the correct MD5 hash
value. This parameter is the single-file equivalent
of 'cache_source_filemtime_ignore_*' configuration
paramters
xto = EXIF Thumbnail Only - set to only extract EXIF
thumbnail and not do any additional processing
ra = Rotate by Angle: angle of rotation in degrees
positive = counterclockwise, negative = clockwise
ar = Auto Rotate: set to "x" to use EXIF orientation
stored by camera. Can also be set to "l" or "L"
for landscape, or "p" or "P" for portrait. "l"
and "P" rotate the image clockwise, "L" and "p"
rotate the image counter-clockwise.
sfn = Source Frame Number - use this frame/page number for
multi-frame/multi-page source images (GIF, TIFF, etc)
aoe = Output Allow Enlarging - override the setting for
$CONFIG['output_allow_enlarging'] (1=on, 0=off)
("far" and "iar" both override this and allow output
larger than input)
iar = Ignore Aspect Ratio - disable proportional resizing
and stretch image to fit "h" & "w" (which must both
be set). (1=on, 0=off) (overrides "far")
far = Force Aspect Ratio - image will be created at size
specified by "w" and "h" (which must both be set).
Alignment: L=left,R=right,T=top,B=bottom,C=center
BL,BR,TL,TR use the appropriate direction if the
image is landscape or portrait.
dpi = Dots Per Inch - input DPI setting when importing from
vector image format such as PDF, WMF, etc
sia = Save Image As - default filename to save generated
image as. Specify the base filename, the extension
(eg: ".png") will be automatically added
maxb = MAXimum Byte size - output quality is auto-set to
fit thumbnail into "maxb" bytes (compression
quality is adjusted for JPEG, bit depth is adjusted
for PNG and GIF)
down = filename to save image to. If this is set the
browser will prompt to save to this filename rather
than display the image

Waarom kan het forum niet autoresizen :/

Zelfs het kutforum van IG kan dat xD

Het kan via de Thumb. Het is ook geen automatische scaling code, maar meer bedoeld om te gebruiken voor forum plaatjes.

Anyhow, is nu wel klaar denk ik

De reden dat niet alles geresized wordt kont doordat het forum zo oud is en vroeger ivm internetbeperkingen van gebruikers het gewoon niet haalbaar zou zijn om grote plaatjes steeds maar weee te moeten downloaden. Desondanks worden de avatars nu wel automatisch geresized dus het zou minimale inspanning van Cor kosten om deze code om te zetten. De resize van al upgeloade plaatjes is vooral een functie die op de frontpage gebruikt wordt voor nieuwsberichten.

Klopt, externe plaatjes worden niet geresized op deze manier, dat zal via een andere manier worden gedaan.
