Doc #69903 [Asn->Nab]: function forwardFourierTransformimage returns error

Edit report at https://bugs.php.net/bug.php?id=69903&edit=1 ID: 69903 Updated by: danack@php.net Reported by: lee dot traynor at skeptic dot de Summary: function forwardFourierTransformimage returns error -Status: Assigned +Status: Not a bug Type: Documentation Problem Package: imagick Operating System: Windows XP PHP Version: 5.5.26 Assigned To: danack Block user comment: N Private report: N New Comment: I should have said, checking for whether the method is available before hand is the appropriate thing to do if you are unsure whether the version of Imagick installed is going to have the fourier functions installed or not. $im = new Imagick ("compass_model.png"); if (method_exists($im, 'forwardFourierTransformimage') == false) { throw new Exception("Installed version of Imagick does not support Fourier functions."); } $imagick->forwardFourierTransformimage (true); $imagick->writeImages ("fourier_test.png", false); Previous Comments: ------------------------------------------------------------------------ [2015-06-23 21:32:26] danack@php.net Thank you for the feedback. Here is an example of it working: http://phpimagick.com/Imagick/forwardFourierTransformImage I've double-checked and the method Imagick::forwardfouriertransformimage is definitely not compiled into the Imagick class, if the functions provided by FFTW are not available through ImageMagick. It is a case that the method is not available, rather than being available and just not working if the FFTW stuff isn't available. ------------------------------------------------------------------------ [2015-06-23 16:29:12] lee dot traynor at skeptic dot de The error is: Call to undefined method so it won't even work with imagemagick compiled with fftw support. Please check that this is indeed the case before adding misleading comments to the documentation. ------------------------------------------------------------------------ [2015-06-23 16:20:47] danack@php.net The function is only available if ImageMagick was compiled on a system with the FFTW library. http://www.fftw.org/ I need to add this to the documentation. ------------------------------------------------------------------------ [2015-06-22 17:54:40] lee dot traynor at skeptic dot de Description: ------------ --- From manual page: http://www.php.net/imagick.forwardfouriertransformimage --- Calling this function results in: PHP Fatal error: Call to undefined method Imagick::forwardFourierTransformimage() Test script: --------------- $im = new Imagick ("compass_model.png"); $im->forwardFourierTransformimage (true); $im->writeImages ("fourier_test.png", false); Expected result: ---------------- Saving of magnitude/phase diagrams as "fourier_test-00.png", "fourier_test-01.png" Actual result: -------------- Fatal error ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=69903&edit=1
