“display-mode” property“display-mode” GstDewarpDisplayMode
How to display the dewarped image.
Flags: Read / Write
Default value: Single panorama image
“inner-radius” property“inner-radius” gdouble
Inner radius of the fisheye image donut. If outer radius <= inner radius the element will work in passthrough mode.
Flags: Read / Write
Allowed values: [0,1]
Default value: 0
“interpolation-method” property“interpolation-method” GstDewarpInterpolationMode
Interpolation method to use.
Flags: Read / Write
Default value: A bilinear interpolation
“outer-radius” property“outer-radius” gdouble
Outer radius of the fisheye image donut. If outer radius <= inner radius the element will work in passthrough mode.
Flags: Read / Write
Allowed values: [0,1]
Default value: 0
“x-center” property“x-center” gdouble
X axis center of the fisheye image.
Flags: Read / Write
Allowed values: [0,1]
Default value: 0.5
“x-remap-correction” property“x-remap-correction” gdouble
Correction factor for remapping on x axis. A correction is needed if the fisheye image is not inside a circle.
Flags: Read / Write
Allowed values: [0.1,10]
Default value: 1
“y-center” property“y-center” gdouble
Y axis center of the fisheye image.
Flags: Read / Write
Allowed values: [0,1]
Default value: 0.5
“y-remap-correction” property“y-remap-correction” gdouble
Correction factor for remapping on y axis. A correction is needed if the fisheye image is not inside a circle.
Flags: Read / Write
Allowed values: [0.1,10]
Default value: 1
