  1. Hello, again, Thanks for posting the afdesign file. The lines you are working on seem to be on the "base" layer, which is locked. The elements can't be selected for joining with themselves unless one works in the outline mode. Of you want to add a vertical line, thats not hard if snapping is on. There will be a yellow dot that indicates when the pen is over the line segment. If you want add that line, or modify the existing shape, there are other more complex issues. The existing lines would need to be broken at the junction points, and then rejoined into new shapes. The problem is that the v. 1.6 release does not lock into the break point(s) when adding the node point for making the break. It is only done manually/visually, and is always slightly inaccurate. (Mind, like about 1000th of a point.) The 1.7 beta give a signal marker that indicates when the new node is being placed at the intersection of the various lines. Also, in this particular instance, its more complex, because all the lines are unjoined. There is existing curve line, A & B, and one would need to break both, and join sections A1 + "new" + B1, and A2 + "new copy" + B2. Hope this clarifies things.
  2. Hi, Morten_Hjort, Did you mean you are starting from a .png? I can't find a reference for an .ong file type. And, which image are you trying to dupe? The first at the top, which has dimension marks, or, the next one. w. most of the lines in a reddish tone.? They seem to have different curved shapes. The pen tool can't snap to a pixel representation. Recreating the curved shapes might work better if you started w. approximate shapes, such as ellipses or rounded rectangles, and adjusted those w. the node tool when converted to curves. There are some small asymmetrical curves that will probably need to be made w. rough approximations w. the pen tool, and carefully adjusted. What I could do for a portion. Approximation.afdesign
  3. Well done, and for me, fascinating. Moving antique designs into a digital format helps create and archive of the fine work done before. Well detailed. Both the doors good looks, but also good indication of their function, and their construction.
  4. Hi, demonLaMagra, Here is a quick file saved w. history. You can step thru what I did to come up up w. something close to what I think you want. Some of the steps will probably not explain a lot. Here is my base construction. Make a donut. Center a circular ellipse within it. Convert to curves. Add together. Draw a few lines to make the outside of a wedge shape. Join those. Draw another set of line. Join those w. the earlier set. Give the form a fill. Nest it within the ellipse array, which clips away from view the excess. Draw another shape which will be subtracted from the ellipses. Subtract. Total time, maybe a minute and a half Quickley.afdesign
  5. I recall a post here that mentioned interior and exterior strokes are handled differently than mid-line strokes. If I make 3 letters, and give one a mid stroke , and the others exterior and interior, when opened in Inkscape, the interior and exterior strokes are separate objects. Also, If I use the end-marker stroke option in Inkscape to make an arrow, Affinity does not render it, and Safari and Chrome render it differently. So I suppose different applications construct/interpret SVG in different manners.
  6. Within various constraints, it is fairly easy to generate regular dot patterns using the pen tool. Myself, I think it would make lots more sense for there to be a plug-in extension, and let someone(s) who have the time to satisfy such a niche need to write a routine that those who really need it can buy.

    Hi, pyxl.er, As the saying goes "A journey of a thousand miles starts w. a 1st step," or something like that. So, why the white space between the face and the shoulder?
  8. Perhaps: "From what I've seen, there is no "general" method for calculating the quantization matrix. The quantization matrices are created in a way where after much experimentation, those numbers are the best that give a good SNR and gives good perceptual quality leveraging a decreased file size. Depending on who you talk to, or what product you're using, some use their own quantization matrices. For example, Adobe uses their own quantization matrices in products such as Photoshop and the generation algorithm is a trade secret - we don't know how they derived their quantization matrices." from: https://stackoverflow.com/questions/29215879/how-can-i-generalize-the-quantization-matrix-in-jpeg-compression
  9. I would also say vectorizing is a better way to go. Expanding the bitmap will inevitably make for jaggy lines. But Photo will do a decent quick and dirty. Use the magic wand, select the sine form, and expand the selection a few px. Edit/Fill/Secondary color.
  10. If I use the Mac's default image viewer, Preview, and zoom in 5 times on the larger image, the artifacts are very evident in the sweater. Also a number around the mustache. The smaller one also has some color bleeding from the routine trying to average color changes around the left ear. Also, It seems like there may be some banding in the larger, as if it was scanned.
  11. Yes, mirrored along the horizontal line implied by the rectangular image of the brush at the bottom of the "edit brush" dialog. As illustrated:
  12. Hi, Gaul, IMO, there is enough stuff in the program that it might take you 2 days to try out everything. For myself, it took about 2 mo.s using a minimum of 2 hrs/day to find what I needed easily. I'm somewhat old, and easily distracted, so may have been a bit slow. Its been a bit more that 2 years now, and there are some things that are just becoming obvious to me. I s'pose I'll be just about up to speed when v. 1.7 consumer is released. Look at it this way. You just bought a piano. How long will it take you to learn to play it?
  13. Yes, I made it intentionally off center. I made several a bit like it so I could have a base curve w. brushes w. slightly different colors and shapes so I could make the overall stack look ragged.
  14. Hi, rnbutler87, Here is a sample of a brush stroke I made which intentionally does not center along the path. When flipped, it does the same thing. W/o repositioning the nodes, the bitmap can't be in the same place, because it does not mirror across the path axis.
  15. It appears to me that there are .jpg compression artifacts in both images. So by reducing the size, the sample blocks are merged into ever coarser averages. I don't do enough image processing to know, but I'll suggest try de-noising the larger, or do a frequency separation before making the image smaller.
