Member Function Documentation

t3lib_stdGraphic::init (  ) 

Init function. Must always call this when using the class. This function will read the configuration information from $GLOBALS['TYPO3_CONF_VARS']['GFX'] can set some values in internal variables.

Returns:
void

Definition at line 236 of file class.t3lib_stdgraphic.php.

References t3lib_div::intInRange(), and t3lib_div::makeInstance().

t3lib_stdGraphic::maskImageOntoImage ( &$  im,
$  conf,
$  workArea 
)

Implements the "IMAGE" GIFBUILDER object, when the "mask" property is true. It reads the two images defined by $conf['file'] and $conf['mask'] and copies the $conf['file'] onto the input image pointer image using the $conf['mask'] as a grayscale mask The operation involves ImageMagick for combining.

Parameters:
pointer GDlib image pointer
array TypoScript array with configuration for the GIFBUILDER object.
array The current working area coordinates.
Returns:
void

t3lib_stdGraphic::copyImageOntoImage ( &$  im,
$  conf,

Implements the "IMAGE" GIFBUILDER object, when the "mask" property is false (using only $conf['file'])

Parameters:
pointer GDlib image pointer
array TypoScript array with configuration for the GIFBUILDER object.
array The current working area coordinates.
Returns:
void

t3lib_stdGraphic::copyGifOntoGif ( &$  im,
$  cpImg,
$  conf,
$  workArea 
)

Copies two GDlib image pointers onto each other, using TypoScript configuration from $conf and the input $workArea definition.

Parameters:
pointer GDlib image pointer, destination (bottom image)
pointer GDlib image pointer, source (top image)
array TypoScript array with the properties for the IMAGE GIFBUILDER object. Only used for the "tile" property value.

$  cpImgCutX,
$  cpImgCutY,
$  w,
$  h,
$  w,
$  h 
)

Alternative function for using the similar PHP function imagecopyresized(). Used for GD2 only.

OK, the reason for this stupid fix is the following story: GD1.x was capable of copying two images together and combining their palettes! GD2 is apparently not. With GD2 only the palette of the dest-image is used which mostly results in totally black images when trying to copy a color-ful image onto the destination. The GD2-fix is to 1) Create a blank TRUE-COLOR image 2) Copy the destination image onto that one 3) Then do the actual operation; Copying the source (top image) onto that 4) ... and return the result pointer. 5) Reduce colors (if we do not, the result may become strange!) It works, but the resulting images is now a true-color PNG which may be very large. So, why not use 'imagetruecolortopalette ($im, TRUE, 256)' - well because it does NOT WORK! So simple is that.

integer The sharpening factor, 0-100 (effectively in 10 steps)
Returns:
string The sharpening command, eg. " -sharpen 3x4"

Parameters:
string The text string to split
boolean Return Unicode numbers instead of chars.
Returns:
array Numerical array with a char as each value.

$  newExt = '',
$  w = '',
$  h = '',
$  params = '',
$  frame = '',
$  options = '',
$  mustCreate = 0 
)

Converts $imagefile to another file in temp-dir of type $newExt (extension).

Parameters:
string The image filepath
string New extension, eg. "gif", "png", "jpg", "tif". If $newExt is NOT set, the new imagefile will be of the original format. If newExt = 'WEB' then one of the web-formats is applied.
string Width. $w / $h is optional. If only one is given the image is scaled proportionally. If an 'm' exists in the $w or $h and if both are present the $w and $h is regarded as the Maximum w/h and the proportions will be kept
string Height. See $w
string Additional ImageMagick parameters.
string Refers to which frame-number to select in the image. '' or 0 will select the first frame, 1 will select the next and so on...
array An array with options passed to getImageScale (see this function).
boolean If set, then another image than the input imagefile MUST be returned. Otherwise you can risk that the input image is good enough regarding messures etc and is of course not rendered to a new, temporary file in typo3temp/. But this option will force it to.
Returns:
array [0]/[1] is w/h, [2] is file extension and [3] is the filename.
