t3lib_stdGraphic::imagecopyresized (  &$  im, $  cpImg, $  Xstart, $  Ystart, $  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. For parameters, see PHP function "imagecopyresized()" Parameters: pointer  see PHP function "imagecopyresized()" pointer  see PHP function "imagecopyresized()" integer  see PHP function "imagecopyresized()" integer  see PHP function "imagecopyresized()" integer  see PHP function "imagecopyresized()" integer  see PHP function "imagecopyresized()" integer  see PHP function "imagecopyresized()" integer  see PHP function "imagecopyresized()" integer  see PHP function "imagecopyresized()" integer  see PHP function "imagecopyresized()" Returns: void private See also: t3lib_iconWorks::imagecopyresized() Definition at line 487 of file class.t3lib_stdgraphic.php.

t3lib_stdGraphic::imageCreateFromFile (  $  sourceImg  )

Creates a new GDlib image resource based on the input image filename. If it fails creating a image from the input file a blank gray image with the dimensions of the input image will be created instead. Parameters: string  Image filename Returns: pointer Image Resource pointer Definition at line 2629 of file class.t3lib_stdgraphic.php. Referenced by copyImageOntoImage(), and maskImageOntoImage().

t3lib_stdGraphic::imageCreateFromGif (  $  sourceImg  )

t3lib_stdGraphic::ImageGif (  $  destImg, $  theImage )

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.

Apply output levels to input image pointer (decreasing contrast) Parameters: integer  GDlib Image Pointer integer  The "low" value (close to 0) integer  The "high" value (close to 255) boolean  If swap, then low and high are swapped.

t3lib_stdGraphic::prependAbsolutePath (  $  fontFile  )

Checks if the $fontFile is already at an absolute path and if not, prepends the correct path. Use PATH_site unless we are in the backend. Call it by t3lib_stdGraphic::prependAbsolutePath() Parameters: string  The font file Returns: string The font file with absolute path. Definition at line 1758 of file class.t3lib_stdgraphic.php.

t3lib_stdGraphic::randomName (   )

Returns a random filename prefixed with "temp_" and then 32 char md5 hash (without extension) from $this->tempPath. Used by functions in this class to create truely temporary files for the on-the-fly processing. These files will most likely be deleted right away.

t3lib_stdGraphic::recodeString (  $  string  )

Recode string Used with text strings for fonts when languages has other character sets. Parameters: string  The text to recode Returns: string The recoded string. Should be UTF-8 output. MAY contain entities (eg. { or " which should render as real chars). Definition at line 1884 of file class.t3lib_stdgraphic.php.

t3lib_stdGraphic::reduceColors (  &$  im, $  limit, $  cols )

Reduce colors in image Parameters: integer  GDlib Image Pointer integer  The max number of colors in the image before a reduction will happen; basically this means that IF the GD image current has the same amount or more colors than $limit define, THEN a reduction is performed. integer  Number of colors to reduce the image to. Returns: void Definition at line 1720 of file class.t3lib_stdgraphic.php.

t3lib_stdGraphic::scale (  &$  im, $  conf )

Implements the "SCALE" GIFBUILDER object Parameters: pointer  GDlib image pointer array  TypoScript array with configuration for the GIFBUILDER object.

t3lib_stdGraphic::singleChars (  $  theText, $  returnUnicodeNumber = FALSE )

Split a string into an array of individual characters The function will look at $this->nativeCharset and if that is set, the input string is expected to be UTF-8 encoded, possibly with entities in it. Otherwise the string is supposed to be a single-byte charset which is just splitted by a for-loop. Parameters: string  The text string to split boolean  Return Unicode numbers instead of chars. Returns: array Numerical array with a char as each value. Definition at line 1906 of file class.t3lib_stdgraphic.php.

t3lib_stdGraphic::SpacedImageTTFText (  &$  im, $  fontSize, $  angle, $  x, $  y, $  Fcolor, $  fontFile, $  text, $  spacing, $  wordSpacing, $  splitRenderingConf, $  sF = 1 )

Printing text onto an image like the PHP function imageTTFText does but in addition it offers options for spacing of letters and words. Spacing is done by printing one char at a time and this means that the spacing is rather uneven and probably not very nice. See Parameters: pointer  (See argument for PHP function imageTTFtext()) integer  (See argument for PHP function imageTTFtext()) integer  (See argument for PHP function imageTTFtext()) integer  (See argument for PHP function imageTTFtext()) integer  (See argument for PHP function imageTTFtext()) integer  (See argument for PHP function imageTTFtext()) string  (See argument for PHP function imageTTFtext()) string  (See argument for PHP function imageTTFtext()).

t3lib_stdGraphic::splitString (  $  string, $  splitRendering, $  fontSize, $  fontFile )

Splitting a string for ImageTTFBBox up into an array where each part has its own configuration options. Parameters: string  UTF-8 string array  Split-rendering configuration from GIFBUILDER TEXT object. integer  Current fontsize string  Current font file Returns: array Array with input string splitted according to configuration Definition at line 998 of file class.t3lib_stdgraphic.php.

t3lib_stdGraphic::txtPosition (  $  conf, $  workArea, $  BB )

Calculates text position for printing the text onto the image based on configuration like alignment and workarea. Parameters: array  TypoScript array for the TEXT GIFBUILDER object array  Workarea definition array  Bounding box information, was set in tslib_gifBuilder::start() Returns: array [0]=x, [1]=y, [2]=w, [3]=h private See also: makeText() Definition at line 652 of file class.t3lib_stdgraphic.php.

t3lib_stdGraphic::v5_blur (  $  factor  )

Returns the IM command for blurring with ImageMagick 5 (when $this->V5_EFFECTS is set). Uses $this->im5fx_blurSteps for translation of the factor to an actual command.
