- Parameters:
-
| min_radius | Minimum radius to consider in an omnidirectional Image. This is done to avoid the super-definition of the pixels near the center. |
| max_radius | The same as min_radius but for the external side. |
| omni_center_x | The x-coordinate that represent the center of the omnidirectional image. It may differ from the normal image center. |
| omni_center_y | The y-coordinate that represent the center of the omnidirectional image. It may differ from the normal image center. |
| video_width | Image width |
| video_height | Image height |
| program_name | In a shader context it's the name of the program that will be uploaded to the GPU (graphic processing unit). |
| vertex_program_file_name | Vertex program path |
| vertex_program_name | Name of the Vertex shader program. |
| fragment_program_file_name | Pixel shader program path. |
| fragment_program_name | Name of the Pixel shader program. |
| flipped_mode | Should the result panoramic image be flipped? This option is useful for special omnidirectional images and flipped mirrors. |

640x480, it returns 1024 as the higher next-power-of-two between 640 -> [1024] and 480 -> [512]. The final video size taken will be 1024x1024, this because of graphic card textures performances.
