  1. Hi, Hematite, Which app? If Designer, use the pencil tool. If Photo, a bit harder, but still do-able. Can you post a pic of something like what you want to do?
  2. Here's my try: Duplicated the background twice. Hid the background. On one, selected tonal range/shadows and feathered 2 px. Inverted then used B&W adjustment layer. Repeated w 2nd dupe, but selected mid-tones. Merged those 2, and used the filter, Colors/erase white paper. Unchecked Document/transparent background. Couldn't find a way to make the "white" any whiter w/o loosing brown.
  3. I was uncertain if the dial GreenGirl was doing required logarithmic markings. if I remember my old slide rule, at least one of the log scales packed ticks in by powers of ten, so the rule would be 10 ticks, subdivided in length x. The next set, dame length, ten tick, less subdivided, but for amounts 10 -100, next set, 100 - 1000. All they same procedure, just more of the same. Hard, but in the sense of lots of repetition.
  4. Hi, GreenGirl, Adding all the numbers & fractions will be the hard part. Making the ticks, not so much. You can use a formula in the rotation transform. In my small example, I drew a vertical line, extending from the center of the page. Made it 2 pt tall, and placed its center of rotation at the center. Did a command Duplicate, and entered 360/600 into the rotation dialogue. Helf down command-J till I had 90 degrees of ticks. Returned to the 1st line, duplicated it, made it 2x as long, and repeated, but w. 360/20 (18 degrees fwiw). This sort of routine will work for any number of divisions and radii.
  5. Good work. Not the easiest thing moving into all vector. One must pretty much think in layers instead of strokes and fills. A bigger tool kit than pencil, paper and eraser.
  6. Pretty much a hobbyist here, but you are mixing pixel layers w. vectors. Typically mixing the 2 causes everything to be rasterized. From the looks of it, the logo could be done in all vectors. Get rid of the masks. Convert the letters to shapes, and XOR them.Ddraw a rectangle over the letter forms, and subtract. FWIW, Adobe considers .eps a legacy file format.
  7. I started w. 6 triangle symbols on a triangular grid. Placed them over the screen shot, and built the center. But when I went to transpose them, realized the screen shot was elongated. That was about 12 minutes. Started again w. the file. Not easy to use. Could see the pattern, but whenever i clicked on a tool, only the 3 letters remained. Eventually got the pattern grid shaped to a triangular grid. Spent time clicking back and forth, drawing the base shape to the sometimes visible text grid. Then copy paste, rotate. Grab the pieces and transpose them, locking to the Affinity grid. Total time, about 30. A good portion of that was flicking back and forth between the text grid view, counting intervals, and then using the pen. With something regular to start w., probably would have been about 6 min.
  8. The nodes are just points along the series from 1st to last that define an area. In and of themselves, only the 1st and last necessary. So copying a portion get the whole thing. If just a section is needed, duplicate the curve, and, using the node tool, break the nodes where needed. That fragments the duplicate line. The unwanted parts can be discarded.
  9. Unfortunately, the boolean operations, and where forms have edges that are close together, the operation(s) for many very small objects. Every red dot node means a separate curve. When you do the second divide, those will all detach, and can be trashed fairly easily.
  10. Booleans always close open curves, and take on the attribute(s) of the lowest in the level hierarchy.

    Digital Art Question

    Hi, MarshallHarrison, Note that w. traditional art, hand/eye skills can take years, even if you start as a child. It may feel a bit silly, but old fashioned "penmanship" exercises can help. Draw lots of circles, parallel lines, squares, triangles, until your arm gets the feel of moving across the rather slick surface of the tablet. At least there is the perfect eraser of "undo."
  12. It appears the .svg export routine generates all sharp points. Bring the .svg export back into Designer, and, in node mode, select the nodes at the ends, and change the nodes to smooth. Re-export.
  13. A lot can be done w. transparency control and blend modes. But from the 2 samples in the 1st post, I'm having trouble trying to figure out exactly what you want to do. Care to offer any shots of quick trials? Or something like you are aiming to do?
  14. The icon samples are quite nice. But the one that is black on white looks flat to me.
  15. Usually when something like this happens its because the shapes were unclosed curves.When a boolean operation like add is used on 2 or more, the operation closes any open curve, adding a stroke to the new connection between the old first and last nodes.
  16. Hi, gabriel_komorov, Why did you change the node to smooth? Leave them sharp. Turn on snapping, and the handles for the nodes can easily be positioned for symmetry. As is the case when moving from any software to another of a similar type, old methods often get in the way of learning the new. FWIW, I used Corel a lot quite a few years ago. I still have a version running on and old "snowball" iMAC G4, and when I started using Designer, I continued using Corel keyboard short cuts for several weeks
  17. Hi, David Scott, Duplicate the hard hat white shape that is under "Wild Bill," and move that to the bottom layer. Everthing above it will have a white background, but the transparency remains elsewhere
  18. Hi, dmont76, Methods mentioned here for PS would work much the same for Affinity Photo.Putting the sketch on its own layer was the 1st thing I thought of. Using an B&W adjustment layer worked fine just now when I tried it.
  19. Some comments. Rake w. grains of salt, .GIF is a really old format, and can only offer 256 colors. Gradients must be dithered, and edge blending is likewise ragged. So simple forms w. a small number of colors are well suited for .gif. The format is 8-bit, and so tends to be small by contemporary standards. .PNG was developed to replace .gif, but accommodates up to 64-bit color depth. In images w. few colors, the .png routine can produce files smaller than .gif. But for images w. greater bit depth the files can become much larger. While ,png will ignore any colors not present, any of the million that are there will be recorded. The format us considered lossless. Add to that the space for transparency, and metadata, and the file size balloons. Also, at one time, the amount of computation necessary for the encoding was noticable. ,JPG is considered lossy, although when the quality is set to 100%, it creates files of about the same size as .png. As compression increases, the routines average areas of color, and use methods that keep the image looking smooth to the eye. Lots of colors, and smooth smears for color gradations. Only at high compression that the artifacts become obvious. The artifacts will be there even for simple forms, so a highly compressed .jpg well not be so good for a geometric shape.
  20. Something I've run across that helps the estimation. After defining the stroke, dash size and gap, expand the stroke, and divide. There will be a count of the new "dash" object. While not exact, as there may be fractional gap lengths, one can get fairly close. See attached, dash - 1 pt, gap = 4, so at least 13.935 cm
  21. Hi, SpongeBob, From what I know, standard snapping snaps to the bounding box corners, mid-points and centers. The center line of the "cross mark" is not at the center of the bounds, and it also has no node to define the point. Also, it is not fitted to the grid, so objects may snap not to the nearest grid intersection. For what I think you are trying to do, you must be in node tool mode, w. the toggles for "snap to geometry of selected curves, : and "snap all selected nodes when dragging" active, and all nodes selected for the object to be positioned.
  22. Note the join options. If you want a sharp corner, change to mitre join, and adjust the miter limit as needed.
  23. Affinty doesn't have a "shape builder" which allows selection of areas only defined by line perimeters. One can, however, dived the 2 expanded triangles, and add the resulting section together to create the same form. The improved pen snapping in v 1.7 makes simple line work like the above quick, and very accurate. It is slightly quicker than dividing and adding pieces.
  24. This is a response to a question by user SunRiseMoon on July 02. 2019. A quick basic drawing lesson. As of this writing, shapes in Affinity designer have 2 attributes, the stroke and fill. Those are defined by vector curve(s). To be filled, those curves can be either open or closed, as long as they surround a 2D area. But if they are open, any "boolean" operation, such as add or divide, will close the curves between the end point of each. This often produces unusable shapes. In Affinity, shapes ar made frome a series of nodes, each one connecting to only those adjacent in the series. The nodes cannot connect to more than 2 other nodes. There is no branching of a curve object. In order to get filled areas of color, if the shape is to be made from the curves that are already there, the curves must be selected, and thru the node tool, joined, and then closed. Sometimes one may need to duplicate existing curves, and cut out sections w. the node tool. These can then be used to create an area that meets shapes that are already there. *** In the owl face example, various strokes were given varying thicknesses by manipulating the pressure curve. Those were "expanded," and added together to form ink like strokes. 3 of the original vector strokes were closed, and so those pen lines could have a fill assigned to them, and for smooth continuous areas of color. Other lines were unclosed shapes positioned either above of below the closed shapes. When the shapes were filled, most were below in the layer hierarchy, and so were hidded by the fill. I selected the "beak" line. See the copies go thru these steps. The line is closed. The closing line is extended upwards for a more natural appearance. A fill is assigned, and the stroke set to "none." the unclosed curve is then matched to the filled curves position, and given a varying line weight. At a reduced size, the beak group was placed over the face. OwlHeadStart.afdesign
  25. Sorry, never ocurred to me that I could do that.
