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

Parameters:

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

Returns:

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.

		$	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	(See argument for PHP function imageTTFtext())
	integer	(See argument for PHP function imageTTFtext())

	string	(See argument for PHP function imageTTFtext()). UTF-8 string, possibly with entities in.
	integer	The spacing of letters in pixels
	integer	The spacing of words in pixels
	array	$splitRenderingConf array
	integer	Scale factor
