render_to_base64

Renders a scene and encodes the rendered image as a base64 string.

arguments

• "canvas_content" : Data (default: "result")

  The string identifier of data to render into the image. May also be a Canvas_parameters object where "type" is a mi::neuraylib::Canvas_type string ("result" for TYPE_RESULT, "post_toon" for TYPE_POST_TOON, etc), and "params" is a map keyed by mi::neuraylib::Canvas_parameter strings ("color_lpe" for PARAM_COLOR_LPE, "index" for PARAM_INDEX, etc).

  Web Services Notes:

  • See the "Canvas names" section of the "Iray Programmers Manual" for a detailed description of supported canvas_content string values and the canvas_pixel_type values required by them. Also see the "Render target canvases" section for a list of canvas type identifiers and their supported parameters when using the extended Canvas_parameters structure.

  Possible Values:

  • result
  • lpexpr=lp-expression
  • result lpexpr=lp-expression
  • alpha
  • alpha lpexpr=lp-expression
  • depth
  • distance
  • normal
  • texture_coordinate[n] - n is the texture coordinate index to return.
  • object_id
  • material_id
  • generated_material_id
  • diffuse
  • specular
  • glossy
  • emission
  • shadow
  • ambient_occlusion
  • irradiance
  • irradiance lpexpr=lp-expression
  • irradiance probe
  • irradiance probe lpexpr=lp-expression
  • convergence_heatmap[i] - i is the index of a previous canvas to apply the effect to
  • toon[i] - i is the index of a previous canvas to apply the effect to

• "canvas_name" : String (default: null)

  The name of the canvas to use. If the canvas exists in the render context (and its resolution/pixel type matches) then the render will target this canvas. Otherwise a new canvas is created. The result will also be stored in the render context under this name.

• "canvas_pixel_type" : String (default: "Rgba")

  The pixel type of the canvas used for the render.

  Web Services Notes:

  • See the "Render target canvases" section of the "Iray Programmers Manual" for a detailed description of supported canvas_content values and the canvas_pixel_type values required by them.

  Possible Values:

  • Rgb
  • Rgba
  • Rgb_fp
  • Color
  • Rgbe
  • Rgbea
  • Rgba_16
  • Rgb_16
  • Sint8
  • Sint32 - eg: for object_id canvas_content.
  • Float32 - eg: for depth canvas_content.
  • Float32<2>
  • Float32<3> - eg: for normal (or any 3D space related) canvas_content.
  • Float32<4> - eg: for texture_coordinate[n] canvas_content.

• "datauri" : Boolean (default: false)

  If true, use datauri format for the resulting image. Otherwise just the direct base64 encoded image is returned.

• "format" : String (default: "jpg")

  The image format to return.

  Possible Values:

  • jpg
  • png
  • tif
  • exr
  • hdr
  • ct
  • array

• "pixel_type" : String (default: "Rgba")

  The pixel type of the returned image.

  Possible Values:

  • Rgb
  • Rgba
  • Rgb_fp
  • Color
  • Rgbe
  • Rgbea
  • Rgba_16
  • Rgb_16
  • Sint8
  • Sint32
  • Float32
  • Float32<2>
  • Float32<3>
  • Float32<4>

• "quality" : String (default: "90")

  The quality of the returned image.

• "render_context_name" : String (default: null)

  The name of the render context to use.

• "render_context_options" : Map (default: null)

  A map of options to be set onto the render context. The value of each of key needs to be another map that contains The "type" and "value". eg {"type": "Sint32", "value": 32}

• "render_context_timeout" : Uint32 (default: 0)

  The timeout for the named render context.

• "renderer" : String (default: null)

  The renderer to use for the render. If not provided then either the renderer specified in the render context, the renderer specified in the scene options or the default renderer is used.

  Possible Values:

  • iray
  • irt
  • blend
  • wireframe
  • lightmap

• "scene_name" : String

  The name of the scene to render.

return value

The encoded image.
