Stabilizer_factor ( float in, ( optional )) – Stabilizer Stroke Factor, Higher values gives a smoother stroke Press Shift for an invert effect (even if this option is not active) Use_stabilizer ( boolean, ( optional )) – Stabilize Stroke, Helper to draw smooth and clean lines. Segment – Use perpendicular segment style.Īrrowstyle_end ( enum in, ( optional )) – None – Don’t use any arrow/style in corner. Mode ( enum in, ( optional )) –ĭraw Straight Lines – Draw straight line segment(s).ĭraw Poly Line – Click to place endpoints of straight line segments (connected).Īrrowstyle_start ( enum in, ( optional )) – Make annotations on the active data Parameters annotate ( mode = 'DRAW', arrowstyle_start = 'NONE', arrowstyle_end = 'NONE', use_stabilizer = False, stabilizer_factor = 0.75, stabilizer_radius = 35, stroke = None, wait_for_input = True ) active_frames_delete_all ( ) ĭelete the active frame(s) of all editable Grease Pencil layers. active_frame_delete ( ) ĭelete the active frame for the active Grease Pencil Layer. If you are interested in learning more about the different object types used in Blender 3D, look at some of the articles we have listed below.Gpencil Operators . We appreciate you taking the time to read through the article, and we hope you found the information you were looking for. If you are using an image sequence as a plane, then choose sequence, and the grease pencil will create a drawing for each frame of that image sequence so that it can be immediately animated. Mode – If you are using a single image, then set this to single to draw the image to the grease pencil. In other words, if there is a part of the image that Blender is not sure how to draw with, the turn policy will influence the result. Turn Policy – This menu of options determines HOW Blender creates paths where there are ambiguities. A lower value can result in less of the image drawn. A higher threshold value may result in more of the image being drawn regardless of contrast. The lower the value, the lower the distance between each generated point and the higher the detail.Ĭolor Threshold – This represents the luminance threshold where the contrast of colors is determined to map out the object. Samples – Similar to the resolution in that it is used to define the level of detail by generating strokes. Scale – The overall size of the created object respective to the image size. Any value greater than two will create a decent result, but the recommended resolution is 5-7. A higher value means greater accuracy but becomes more challenging to work with due to the density. Resolution – This represents the number of points generated for the grease pencil object. The higher the value, the more bloated an image will appear, so keep this at a low value. Thickness – Think of this as the pixel density for each generated point. The selected object option should inherit the name of the image, but at the time of writing, this tool does not seem to work as intended. Target Object – You can decide if you want to designate it as a new or selected object. In most cases, the default settings here will be the best settings to go with anyway, but we will run through what each setting is designed to do. The second option stands out and is labeled ‘Trace Image To Grease Pencil.’ There are several options here explicitly related to the current object type. Select the image and then press the right mouse button, which will bring up the object context menu. That does not mean that we can’t perform the conversion, as there is another method. Locate the conversion option, and you will have several options for what you want to convert the selected object to.įor whatever reason, though, none of these options seem to work with image objects, and that includes the grease pencil. The traditional means of converting an object is first to select it and then go to the object menu in the viewport. Hence, it has similar properties to an image that allow conversion to be possible. We can sort of do this anyway with the import images as planes add-on, but that would import the image as a how and just map it to the plane as a texture.Ī grease pencil, however, is an object created by drawing your lines and is primarily used for 2D animation. Converting An Image To A Grease Pencil Objectīlender can convert objects to different types so long that these objects possess the properties that will allow for conversion.īecause we are working with a 2D image, we will not be able to convert an image into a mesh directly. Another tip is to use black and white images, as the grease pencil conversion will use contrast to create a monochrome version of the image.Ĭolor is fine, but you can get better accuracy if you use a greyscale image for the comversion.
