    39. 

  39.  * With TYPO3 4.4 GDlib 1.x support was dropped, also an option from $TYPO3_CONF_VARS
    40. 

  40.  * $TYPO3_CONF_VARS['GFX']['gdlib_2'] = 0,	// String/Boolean. Set this if you are using the new GDlib 2.0.1+. If you don't set this flag and still use GDlib2, you might encounter strange behaviours like black images etc. This feature might take effect only if ImageMagick is installed and working as well! You can also use the value "no_imagecopyresized_fix" - in that case it will NOT try to fix a known issue where "imagecopyresized" does not work correctly.

    440. 

  440. 	 * OK, the reason for this stupid fix is the following story:
    441. 

  441. 	 * GD1.x was capable of copying two images together and combining their palettes! GD2 is apparently not.
    442. 

  442. 	 * With GD2 only the palette of the dest-image is used which mostly results in totally black images when trying to
    443. 

  443. 	 * copy a color-ful image onto the destination.
    444. 

  444. 	 * The GD2-fix is to
    445. 

  445. 	 *		 1) Create a blank TRUE-COLOR image
    446. 

  446. 	 *		 2) Copy the destination image onto that one
    447. 

  447. 	 *		 3) Then do the actual operation; Copying the source (top image) onto that
    448. 

  448. 	 *		 4) ... and return the result pointer.
    449. 

  449. 	 *		 5) Reduce colors (if we do not, the result may become strange!)
    450. 

  450. 	 * It works, but the resulting images is now a true-color PNG which may be very large.
    451. 

  451. 	 * So, why not use 'imagetruecolortopalette ($im, TRUE, 256)' - well because it does NOT WORK! So simple is that.
