  1. 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."


  2. 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

  3. 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.


  4. 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

  5. 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.

     


  6. 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.

  7. Hello, SunRiseMoon,

    I hope the translator works for this:

    My guess is that the lines were made from pen strokes. The strokes had their pressure curves modified to make tapers and swells. Then the pen strokes were "expanded, and added together. Expanding strokes can make shapes w. huge numbers of nodes, but I've found that if the strokes start rather simples, and are smooth, the final curve shape can have not too many nodes.

    Here is the file. For the fun of doing it, I colored the lines. The fills can be in-painted however on likes.

  8. From the screen grabs, it looks like the letters are individual objects, and I'd expect to be able to select each or all, and, using the fill pop-out, assign color of gradient. The wall, however is just a collection of lines. Affinity doesn't work like a paint program. To fill an area, it must have a surrounding vector. You might try selecting the outer boundary of the wall, and join the curves w. the node tool. Then that can have a fill, and the brick lines and letters can be on a layer above.
