specified site’s page, returning whatever string the server returns. Not suitable for binary data. The args must be an encoded string of

name=value&name2=value2&name3=value3 etc, where the values have been URL- encoded. The site should not have any “http:” prefix.

.importFile During a Sizzle Import, the name of the file being imported ( note import file name, not openinp-type input file name).

.info Access to the user’s Description of the scene file on the File/File Info dialog, read/write.

.InvertUVMap(srcfnm, w, h, pxasp, dstfnm) Write the inverse of the RG-color-

coded distortion map stored in the file srcfnm to the file dstfnm. The new map will have the given width, height, and pixelaspect (which should be 1.0!). Note that inversion is slow and subject to edge effects, always use Shot.WriteRedistortImage() for SynthEyes- generated maps—this is only for externally supplied maps. The source map should have floating point channels; 16bit may have artifacts.

.IsScriptIgnored(fnm) Returns 1 if the filename (script, toolbar, etc)

is being ignored as a result of the tidy up scripts analysis, zero if it is not.

.JSONdecode(string) Produce a general potentially-nested Sizzle

object from a JSON-encoded string. Note that the special values true and false can be produced, see Builtin Variables.

.JSONencode(jsonobj) Produce a JSON-encoded string from a

general Sizzle object with nested generic lists.

.JSONread(filename) Read a JSON-encoded file, producing a

general Sizzle object with nested generic lists etc. In the event of an error, the result is null. Note that the special values true and false can be produced, see Builtin Variables.

.JSONwrite(fnm, obj) Write a potentially nested Sizzle object to a

file in JSON format. Returns 1 for success, 0 for failure. An error will be reported if there is an illegal component in obj (eg a Vector).

.keepWorldSize Keep the same world size while solving; don’t change it automatically. SynthEyes’s automatic world size update routine is designed to maximize numeric accuracy while solving, so turning that off should only be done carefully. Use Edit/Scene Settings to

directly control scene-size-related numbers, rather than disabling the auto-update.

.lastSavedFileName This is the filename from when this file was

last saved and re-opened. It is NOT affected by any saves that took place during the current session. This is used to re-find files when the whole project moves.

.lensPresets Returns a list of lens preset names.

.level Return 0: Demo, 1: Intro, 2: Pro

.LoadColorMap(fnm) Loads or reloads a colormap file, so that a

recently-written file is seen.

.LoadLens(fnm) Loads or reloads a lens preset file or image, so that a recently-written file is seen.

.macaddr The computer's reference MAC address, for use generating standard unique identifiers. Fields may separated by hyphens (Win) or colons (Mac/Linux).

.mapColor(colorvec, mapname) Maps a color, stored as an rgb vector,

through the named 3-D LUT — any currently- available map, independent of whether or not it is used for any shot. Result is also a vector. Uses floating-point path with nominal range of 0..1 for each channel, though out of range elements can be handled with the 1-D pre- maps, and any output range is permissible as set by the map. Use for tasks such as composing two maps.

.marketing The BorisFX marketing version of SynthEyes, ie a year plus fraction number like SynthEyes 2024.5. This is a string not a number, to accommodate whatever may come along.

See also .release and .version.

.matchFrameNumbers OBSOLETE. Use Shot.matchFrameNumbers.

Using this value will trigger an error. The match-frames value (read-only).

.maxiters Maximum solver iterations before moving on.

.meshDeDupeMode Mesh de-duplication mode for the current

scene. If -1, go to the preference instead.

.mon0Position The main monitor's top-left position in pixels (a point).

.mon0Size The main monitor's size in pixels (a point)

.mon1Position The secondary monitor's top-left position in pixels (a point), or (0,0) if none.

.mon1Size The secondary monitor's size in pixels (a point), or (0,0) if none.

.mon2Position The tertiary monitor's top-left position in pixels (a point), or (0,0) if none.

.ClearMRUexport and .GetMRUexport.

.MRUfile The most-recently-used SNI file. When written, adds the new one to the head of the list and bumps the others down. See also

.ClearMRUfile and .GetMRUfile.

.MRUscript The most-recently-used script. When written, adds the new one to the head of the list and bumps the others down. See also

.ClearMRUscript and .GetMRUscript.

.NewImage(format, wid, hei) Create a new RGB image with the specified

format (see Image.format for definitions). Write the new image's .hasAlpha to add an alpha channel if needed.

.NewPhase(kind) Creates a new solver phase of the specified kind. The kind can be either a small integer, from a phase.kind, or the exact phase name from the Add-phase menu. Since it's possible the names may change occasionally for clarity, using the number is preferred. Returns

-1 for invalid kind numbers.

.nMonitor The number of monitors on the current machine

.NPhaseKind() Number of phase kinds, ie the small integers run from 1 to NPhaseKind() inclusive, with the possibility of occasional gaps (returning -1 from NewPhase).

.OpenFile(prompt, starting, extensions) Opens a file-open selection dialog with

the given prompt (dialog title), starting filename and/or directory, and space- separated list of extensions. The operating system may ignore starting specifications that include solely a directory, unfortunately.

Unlike SaveFile, OpenFile requires that the file already exist.

.OpenInBrowser(fnm)* Open the local file in the browser, taken

liberally to mean the program defined to open that type of file on the machine.

.OSbits 32 on 32-bit operating systems, 64 on Windows XP-64 or Vista-64. Note that 64-bit operation requires a 64-bit processor, a 64-bit Operating System, and a 64-bit license and installation of SynthEyes.

.perspVergeDistance Default vergence distance for stereo views

generated by the perspective view.

.playStart Start of playback range on time bar. Keep to a valid value for the active shot, less than the playEnd value. This means you will need to change Start or End first, depending on the situation.

.playStart1 ─ .playStart4 Starting frame for each of the four user-

defined playback ranges on the time bar.

.playEnd End of playback range on time bar. Keep to a valid value for the active shot, greater than the playStart value. This means you will need to change Start or End first, depending on the situation.

.playEnd1 ─ .playEnd4 Ending frame for each of the four user-

defined playback ranges on the time bar.

.playRate Relative playback rate multiplier, positive or negative. The value 0.001 means step-by- step.

.ReadDirectory(template) Takes a simple template like

"D:/Shots/Project1/*.png" and returns the list of file names matching the template. The file names do not have the directory, they do have the extension. There can be a single * in the template's filename, and the extension can be given or be a *. (Simple version of FindFirst/NextFile.) For more complex matching, do it directly.

.ReadFile(filename) Read the contents of a text file (with any file

extension) and return the contents as one long string. Returns null if the file can’t be opened or read.

.ReadImage(filename) Read the image from this filename, returning

the new Image object, or null if it can't be read.

.ReadJSON(filename) See JSONread()

.ReadLidar(filename)* Reads a Lidar (.xyz) file, returning either the

new mesh, or a null pointer if the file can not be read properly. Includes per-vertex color if present.

.ReadMesh(filename)* Reads a mesh from the given file (the file

extension is examined to determine its type), returning 1 on success, or 0 on failure.

.ReadOBJ(filename)* Reads an OBJ file, returning either the new

mesh, or a null pointer if the file can not be read properly.

.ReadSBM(filename)* Reads an SBM file, returning either the new

mesh, or a null pointer if the file can not be read properly.

returning a new XMLNode for examination and manipulation. Returns null if the file can not be read.

.ReadYAML(filename) See YAMLread()

.recalcSplines Set this to zero before making many changes to a camera or moving object's seed or solved paths (regular or FOV) to save time and reduce memory consumption.

.Redraw() Redraw the main user interface. Make sure the scene is in a consistent state before doing this.

.release Traditional SynthEyes NNNN release version, for example the number 2304. See also

.marketing and .version.

.rootPhase Returns the root solver phase in the scene, or null if there is none.

.runTextures Rerun texture extractions after a solve.

.RunTrackersBwd() Run all "backwards" trackers at the current frame. Returns the total number of auto-keys that were set.

.RunTrackersFwd() Run all "forwards" trackers at the current frame. Returns the total number of auto-keys that were set.

.Save(filename) Saves the .sni file to this name, intended for setting up batch operations. Return value is 1 for success, 0 failure.

.SaveFile(prompt, starting, extensions) Opens a file-save dialog with the given

prompt (dialog title), starting filename and/or directory, and space-separated list of extensions. The operating system may ignore starting specifications that include solely a directory, unfortunately. Note that unlike OpenFile, this version allows you to select a non-existent file, and prompts for overwrite if it exists.

.scriptFile The file name of the running script

.ScrollSolverViewToEnd() Scrolls all solver views to their end, ie after

appending more text.

.selected The (single) thing selected in the user interface. Use typeof to determine what it is: SynMesh, SynObj, SynTrk, SynLite, SynExtraPt. Can be written to select some single thing, including setting it to null to unselect.

.selectedSpline Currently-selected spline, read/write.

.SetCompression(extn, initial) Show the output image/movie compression

setting dialog for files with the given extension extn, starting with the given initial setting. If the initial setting is blank or from a different extension, the most-recent settings for this extension will be used, or if unused in this run, its default settings (which is the standard sequence). Conveniently stored in a Hidden() UI field and launched from a Button().

.SetFolderPref(i, foldername) Set the preference for the given index (see

FolderPref) to the given foldername. See also the FolderPref object.

.SetFrame(frm) Sets the user-interface frame number to the specified frame. This is independent of the frame variable within Sizzle.

.shadowColor 24b RGB color of shadows in the perspective view, at full blending. Initialized from the preference.

.Shutdown(quietly) Immediately terminate running the script, and shut down SynthEyes. If the file has changed, a save dialog will appear, but if the numeric quiet argument is non-zero, the file will be marked as already-written, and no dialog will appear. Running a script will often constitute a change, if it does something! The function will terminate any type of script, but only a tool script can close SynthEyes.

.Solve()* Solve entire scene, as per Go! button. No user interface or cancellation while running.

.solverOutput Long text string: all the messages produced during the last solve. WARNING: not thread- safe, don't read or write during a solve. Is this matters to you, let us know!

.sourceFile Source .sni file name

.spinalLockWeight Spinal Editing parameter.

.threadsUse The number of threads, as modified by SynthEyes’s Multi-processing preference. Can be zero if multithreading is disabled.

.TidyUpScripts(force) Runs the process to tidy up scripts. Its user

interface will appear if ignored files are detected, or if force is nonzero. Returns the number of ignored files ( after the dialog, if it opens).

.troubleMode What to do if the solver encounters trouble; see the tooltip for “Solving trouble mode” on the Advanced Solver Settings.

.txComputeTextures() Extract all textures in the scene. This is more

efficient than computing each texture separately. No cancellation is possible. Return: 0:fail, 1:pass.

.uniqueID A unique ID string (representing a 64-bit integer)

.UpdatePrepSetsFromFile(kind, fnm) Update all prepsets on all shots from

those stored in a .prp file earlier by SavePrepSetsToFile(). No new prepsets are created: only existing ones are updated. The prepsets are labeled as the specified kind: scene:0, imported:1, preference:2. Returns the number of affected prepsets, or -1 in the case of an error (such as unreadable file).

See also Shot.LoadPrepSetsFromFile().

.useAltColor Use the alternate color slot for trackers, see Tracker's .color, .primColor, .altColor

.creatorID.

.WriteJSON(fnm, obj) See JSONwrite()

.WriteYAML(fnm, obj) See YAMLwrite()

.WriteTranslationTemplate(fnm) Writes a CSV template file for machine

translation of tooltips and menus. Should have a .csv extension.

.YAMLdecode(string) Produce a general potentially-nested Sizzle

object from a YAML-encoded string. Note that the special values true and false can be produced, see Builtin Variables. Use JSON over YAML if possible.

.YAMLencode(jsonobj) Produce a YAML-encoded string from a

general Sizzle object with nested generic lists. Use JSON over YAML if possible.

.YAMLread(filename) Read a YAML-encoded file, producing a

general Sizzle object with nested generic lists etc. In the event of an error, the result is null. Note that the special values true and false can be produced, see Builtin Variables. Use JSON over YAML if possible.
