| 68 These configuration values can be changed at runtime by including this in your | |
| 69 program: | |
| 70 | |
| 71 <!--?prettify?--> | |
| 72 ~~~~ | |
| 73 #include "SkRTConf.h" | |
| 74 /*...*/ | |

| 76 SK_CONF_SET( configuration_name, new_value ); | |
| 77 /*...*/ | |
| 78 ~~~~ | |
| 79 | |
| 80 Or by setting the corresponding environment variable before starting the | |
| 81 program. For example, in Bourne shell: | |
| 82 | |
| 83 <!--?prettify?--> | |
| 84 ~~~~ | |
| 85 #!/bin/sh | |
| 86 export skia_environment_variable="new_value" | |
| 87 your_program | |
