• Calling ffmpeg from php

  7 juillet 2013, par v3ga

  I need to run ffmpeg from a php script. The ffmpeg wiki page on the same topic (http://ffmpeg.org/trac/ffmpeg/wiki/Using%20FFmpeg%20from%20PHP%20scripts) suggests using shell_exec over ffmpeg-php. Some other pages suggests using ffmpeg-php. Which method is better ? Is ffmpeg-php compatible with latest versions of php ? My only purpose is to convert any videos hosted by the user into mp4 (h.264,aac).

• Evolution #4036 : [Compresseur] Rechercher la présence événtuelle de .min.(js|css) dans le nom de ...

  L’idée me semble intéressante, même si elle risque de complexifier le comportement du compresseur. Voyons ce qu’en pense le reste de l’équipe, en attendant je bascule vers la branche 3.4.

  Pour le point 1 je pense que c’est bien, ce serait plutôt pas mal même

  Le point 2 me semble plus tiré par les cheveux perso

• Creating buttons with Imagick

  9 juin 2010, par Mikko Koppanen — Imagick, PHP stuff

  A fellow called kakapo asked me to create a button with Imagick. He had an image of the button and a Photoshop tutorial but unfortunately the tutorial was in Chinese. My Chinese is a bit rusty so it will take a little longer to create that specific button

  The button in this example is created after this tutorial http://xeonfx.com/tutorials/easy-button-tutorial/ (yes, I googled “easy button tutorial”). The code and the button it creates are both very simple but the effect looks really nice.

  Here we go with the code :

  php

  < view plain text >

  1. < ?php
  2.  
  3. /* Create a new Imagick object */
  4. $im = new Imagick() ;
  5.  
  6. /* Create empty canvas */
  7. $im->newImage( 200, 200, "white", "png" ) ;
  8.  
  9. /* Create the object used to draw */
  10. $draw = new ImagickDraw() ;
  11.  
  12. /* Set the button color.
  13.   Changing this value changes the color of the button */
  14. $draw->setFillColor( "#4096EE" ) ;
  15.  
  16. /* Create the outer circle */
  17. $draw->circle( 50, 50, 70, 70 ) ;
  18.  
  19. /* Create the smaller circle on the button */
  20. $draw->setFillColor( "white" ) ;
  21.  
  22. /* Semi-opaque fill */
  23. $draw->setFillAlpha( 0.2 ) ;
  24.  
  25. /* Draw the circle */
  26. $draw->circle( 50, 50, 68, 68 ) ;
  27.  
  28. /* Set the font */
  29. $draw->setFont( "./test1.ttf" ) ;
  30.  
  31. /* This is the alpha value used to annotate */
  32. $draw->setFillAlpha( 0.17 ) ;
  33.  
  34. /* Draw a curve on the button with 17% opaque fill */
  35. $draw->bezier( array(
  36.           array( "x" => 10 , "y" => 25 ),
  37.           array( "x" => 39, "y" => 49 ),
  38.           array( "x" => 60, "y" => 55 ),
  39.           array( "x" => 75, "y" => 70 ),
  40.           array( "x" => 100, "y" => 70 ),
  41.           array( "x" => 100, "y" => 10 ),
  42.          ) ) ;
  43.  
  44. /* Render all pending operations on the image */       
  45. $im->drawImage( $draw ) ;
  46.  
  47. /* Set fill to fully opaque */
  48. $draw->setFillAlpha( 1 ) ;
  49.  
  50. /* Set the font size to 30 */
  51. $draw->setFontSize( 30 ) ;
  52.  
  53. /* The text on the */
  54. $draw->setFillColor( "white" ) ;
  55.  
  56. /* Annotate the text */
  57. $im->annotateImage( $draw, 38, 55, 0, "go" ) ;
  58.  
  59. /* Trim extra area out of the image */
  60. $im->trimImage( 0 ) ;
  61.  
  62. /* Output the image */
  63. header( "Content-Type : image/png" ) ;
  64. echo $im ;
  65.  
  66.  ?>

  And here is a few buttons I created by changing the fill color value :
