    The transformation matrix of an object is influencing how the brush texture is mapped onto the path(s) of an object. If you select your two curves and do Merge Curves then they will be stroked in a matching way, and then you can do Separate Curves if you require them to be separate objects.

    Your Layers panel shows you have set the opacity of the Gaussian Blur to 0%. That needs to be 100%, as it is in the file I provided.

    The image I posted alongside an Affinity document is a PNG export from that Affinity document, so I cannot understand why an export does not work correctly for you.

    It is that value in the field to the immediate right of the "+". That has tooltip "Set the angle of the partial turn of the spiral" and the value is in degrees in the macOS app.
  6. lepr
    The partial turn angle is effective for all of the spiral styles, but minimum radius of the decaying style needs to be small enough to allow all turns and the partial turn to be drawn.

    The Boolean geometry Subtract command still has no option to create open paths when punching a region out of an object. However, the Shape Builder tool of v2 may give you a slightly faster workflow than you had in v1. See attached video. tabs.mp4

    The firstdefence selection method gives a selection intensity of the maximum of R, G and B for each pixel. I wouldn't use that method because it can result in a perceptually dark colour being considered as having greater intensity than a perceptually bright colour. The smadell selection method gives a selection intensity of the perceived brightness (maybe luminosity or maybe luminance or maybe luma or some such measure of "brightness") for each pixel.

    Yes, position any object above the master tile of the Pattern and then use Merge Down command to incorporate into the Pattern.

    The group transformation error has something to do with Artboard location in the document space. If you first rearrange the Artboards so 'Task Details' has its origin at top left of all, then the subsequent grouping will be performed correctly. That is proposed as a workaround to help get your project finished. There is a bug to be fixed by the developers.

    You've used the per-turn decay option. I told you to use the per-segment decay option and the "1 - cos(a)" expression.
  13. lepr
    93.75% is the decay of the radius for one turn of a 4-gon spiral only. It's different for each n-gon. Instead of explaining how to calculate the per-turn decay for an n-gon spiral, it's easier to tell you to use the per-segment decay option and enter the expression "1-cos(a)", without quote marks and where a is the segment angle.
  14. lepr
    The segment angle for the spiral is ½ of the exterior angle of the polygon, so that's 180/n, where n is the number of sides of the polygon.

    Surely the most flexible and straightforward solution would be to simply recover the base object of the Shape Text. That could then be converted to curves if the user specifically wants a Curve/Curves object instead of a parametric shape.
  16. lepr
    No, the parametric shape remains as the basis of the Shape Text, and its controls are available with Node Tool as usual, so the developers could easily provide a means of getting the parametric shape object from a Shape Text without a conversion to Curves.
  17. lepr
    It can, but you'll need to calculate the decay percentage for a given polygon: cusped decaying spirals.afdesign

    Note that the black lines in your document are stroked with Affinity so-called vector brushes which really stretch or repeat a raster image along a path, and so you won't get a purely vector export from it.

    A suggestion: The Useless Live Filter
  20. lepr
    You're welcome! Today I attached a new 'procedural gradient.afphoto' file to my earlier comment. Its Procedural Texture uses some vector functions that are provided by Affinity, which might help you with learning about the functions.

    Publisher has a Text Frame panel for controlling properties of the object that is providing the path for text or a frame for text.

    I'm not sure why you are bothering to state that. The video shows the expansion is happening, but the result is too skinny because of the bug I wrote about earlier in this thread.
  23. lepr
    A trick that suppresses dithering of a vector gradient when exporting to a raster format: give the gradient-filled object an FX Colour Overlay with zero opacity: gradient tool gradient.afphoto An alternative way to avoid dithering is to use an FX Gradient Overlay on an object: gradient overlay gradient.afphoto This document contains a Procedural Texture gradient: procedural gradient.afphoto

    It's an ancient permabug that has been known to Serif for many years: an expanded stroke will be too thin when Size Variance in the stroke properties is not 100%. The closer to 0%, the greater the error in the expansion.
  25. lepr
    You may be thinking of a Compound (non-destructive Boolean geometry) rather than a Group or Layer, because colouring a Compound does not affect its contained objects.
