  1. Do you have a layer selected? And is the layer a "pixel" or an "image?" I don't use Photo that much, and often forget to select/high lite a layer before applying an adjustment, or using a tool like a dodge brush. Pixel/rasterized layers can have various adjustments made on them, but "images" can only be re-sized and have opacity and blend mode changes. They need to be rasterized before adjustments can be made on them.
  2. Clear and concise. Good work, and good demonstration.
  3. In Affinity, the stroke is not an object. It is just an attribute of the curve geometry. I don't use Inkscape enough to say, but in affinity, Expand stroke may be like convert to path in Inkscape. It makes a filled area that was the stroke, and that can be cut away.
  4. Hi, webcat, I'm not familiar w. the term knock-out, but I suppose you mean you want to remove the rectangle(s) or star shape from the diamond. The objects do not need to be converted to curves. When they go thru a boolean operation, such as subtract, the results will be a curve. Your 1st problem was that you only had 1 on the rectangles selected when you did the subtract. So only one was cut away. If you had all the shapes selected, the 2 rectangles above the diamond would have both been subtracted. The order of the operation is from top of the stack down, so when the diamond was on top, it cut away from the rectangle. The results of the operation have the attributes of the bottom object. So if you subtract any shape from one that has an outline, the resulting shape will still have the outline. I'm not quite sure what was going on w. the star example, the star arms should have been cut away from the diamond. Attached, a file saved w. history so you can step thru what I did. I hope this is what you were aiming at. Knockout.afdesign
  5. None of this is really elementary. Work has been done on these problems for at least 30 years. This is an over simplification. If the project depends on photo or artistic images, Photo will probably be better. If clean shapes, smooth gradients, and transparency fades on those do most of the job, go w. Designer. But most work has some overlap, so both apps have elements of the other. To choose the starting point. If you want to make an image that depends on a photographic, or at least photo derived picture, start w. Photo. It has many tools for making adjustments to all aspects of color. If the image needs some shape manipulations, such as blurs, or shape corrections or distortions, Photo is made for that. One can then add text, or shape design elements like logos. Designer is better suited to making vector shapes, and laying them out within various spaces, such as business cards, or mobile device screens. Or (something of which I do very little) isometric mechanical/architectural renderings. It does do some image processing, but nothing as extensive as Photo does.
  6. I was using the flood select tool. When doing a contiguous select, it will grab everything within the tolerance. So it grabs a whole blob of the watercolor. The selection bush will do much the same thing, but can be limited to just the area within the brush nib selection. Then copy, and paste, which creates a new layer. Using the move tool, position the duplicate where you like, and transform it in proportion and rotation as you like. Merge down, changing the opacity and blend mode as you might like.
  7. If you look at the view modes in Designer, on the Mac, there are 4 view modes, pixel, pixel (retina), vector and outline. If you switch between them, you will notice that you have representations in Photo that are similar to the pixel views in Designer. Designer is made to let one makes shapes to the maximum that can be displayed at different zoom levels in the vector modes. The pixel representation is limited to high definition at 100% zoom. When the vectors are transferred to Photo, they can only be represented in their pixellated form. If you are familiar w. music, consider this analogy. A stretched string will produce hundreds or thousands of individual notes, depending on where it is stopped. But a piano uses a set of 12 strings of certain proportions of the much larger number. That is similar to the difference between vector and raster graphics. You can have many thousands of points along a line, or 144, which is the current maximum for computer displays on the market.
  8. Indeed, hard to say what is the best way. I've done things vaguely like this before. So thrashed around a bit until I hit the "Oh! that worked..." moment. Then, variation, variation.
  9. And another approach. Used clone brush to dabble over the letters. Not happy w. the result. Started using the wand select, copying and pasting various selections from the upper veggies. Transformed them in different ways, reduced opacity, and merged down. Some times changed the blend mode to screen or soft light. Then used the wand again to catch most of the lower grassy area, and added a bit of monochromatic noise to hint at the original paper. Oh, and used the smudge brush w. a coarse bristle nib to break up some of the patch edges.
  10. Hi, VJSHawaii, "Is there a way to link a design (or symbol) but have it match an area that differs in dimension? " Symbol objects can have different dimensions. See attached. Everything was initially 2 instances of a symbol comprised of 4 identical red squares. By turning synching off and on, I changed the dimensions, colors, periphery shapes, etc. My experience w. symbols is somewhat limited, but I have noted that there are some operations that will cause symbol elements to detach, and they can not be re-synched. Unfortunatelly, I haven't worked out what exactly is happening in those cases. Looking at the example illu you posted, I suppose that if it is possible to build symbol(s) to update across the seeming 3D objects, it will nevertheless be quite hard to make. If you want to just change colors, you can create global colors for the panels, and the color fill can update everywhere the colors appear.
  11. I get this pretty often. For instance, I've may have something like 14K objects all bottom aligned, and I want to marquee select those that stick up a certain amount. I'll get the alert while each of the 5 - 6 K objects are being put into the selection. Its nothing to worry about, it just means the snapping sub-routine can't update while all the enumeration goes on.
  12. Like it. You have a great way w. stylization. Don't have my iPad running just now, but on the desktop, the Preferences setting "user interface" allows showing units to finer levels of decimal precision.
  13. Its a quote from musician Frank Zappa, who also said "There is more stupidity than hydrogen in the universe, and it has a longer shelf life."
  14. A pen stroke, w. radial gradient, topped by another, but thinner and set to screen blend mode, and a transparency fade from dark end to light.
  15. Looking at the dimensions, I'm guessing the lightbox is a very slightly distorted square. The best I can make is a reasonable approximation, an average. But, yes, as far as I can tell there are any number of shapes that can be made having only the lengths and no angle or diagonal reference. Going off topic, hereinafter acronymized as GOT, I'm reaching infinity years beyond the last time I needed to use anything beyond elementary geometry. But I do have 2 grandkids. Once they get beyond the anything small enough goes in the mouth stage, I'll be sending them "K'nex" and then "Zometools." I hope those will fascinate them. Early starts in anything is good. Honestly, start playing Bach by age 6 latest, assuming there is a competent teacher.
  16. Seems like the inaccurate drawing is technically not a technical drawing. I searched around, focusing on threads from CAD forums. Some respondents said that w/o at least 1 angle it was impossible. 1 respondent claimed to have a solution, but ended up admitting that it was just less inaccurate than other proposals. I've tried "fiddly" in 1.6, am going to try 1.7. But if CAD users don't have a method for doing this, I have to wonder how a design illustration app would be useful. Any rate, another question. Do you have at least a sequence for the 4 lines. That is, A = w, B = x, C = y, D = z?
  17. Can you be more specific? Do you only have a list of the lengths? Something like A B = 12, B C = 13, etc? Seems like if a series of circles w. those radii were made, it shouldn't be too hard. Or, w. some fuss, create a protractor w. the cog tool.

    Creating Jagged Edges

    Attached image mostly done on the iPad. I really don't use it enough to be fluent, and so did some later work on the desktop. Basic method. Draw pen lines w. pressure curve adjustments. I expanded those, and added many together. There were a lot of strokes that turned into "curves" objects. Those needed to be self divided, and the tiny bits selected, and thrown away. Then, 2 different operations. Made a pencil scribble over the animal shape, and expanded that. Subtracted it from the animal. Selected all nodes, made them smooth, and then used the smoothing routine to make it look gloppier. Selected portions, duplicated, and gave the duplicates a square dotted line. Expanded the stroke, and subtracted that from the previous shape. Again, selected all nodes, made them smooth, and then used the smoothing routine to make it look gloppier. In some places, drew more lines over the shape, and subtracted the expanded strokes. Continued selecting some smaller portions, making the strokes dotted, and expanding. Copied those, and moved them around, and then subtracted them from the underlying expanded strokes. Somewhat labor intensive, but it does allow for some areas to be more irregular than other. Seems like a good thing to me.

    Creating Jagged Edges

    Hi, eneuman93, I think it is do-able. I don't use my iPad much. It appears I'd been using the beta version, which had expired, and so am d-loading Designer again. My connection is hideously slow, been about an hour, and still have about 40% to go. I do think something similar can be done, been meesing about w. the desktop version. But looking at the image you showed, I'm reminded that Illustrator had a feature called punk&bloat, which randomized nodes. Affinity doesn't have that, and there was a comment a few years ago that it was not likely it would. I may get back in awhile w. some results, but I do have some things I must get done.

    Hi, kconkling, Just to clarify a little. Text, parametric shapes, free-hand pen shapes, etc, when saved as .svg remain vectors. This means they will be displayed at any size up to the resolution the display device can manage. The exception is if a bitmap has been used as a fill. That will be scaled more or less successfully depending on the image.
  21. Hi, Foomandoonian, This issue has come up more than a few times. It appears when shapes of the same color are butted together. The 1st time I encountered the problem, the thread mentioned that it was an anti-aliasing routine problem. Essentially, the white of the background was being added into the color of the shape. There are 2 solutions. One is to turn "precise clipping" in the performance preference. The other is to add a centered stroke of the same color. I'm not sure how thin the stroke can be. I have a file open just now, and a stroke as thin as .04 pt works. There have been some problems w. booleans when points have a particular geometry. My recollection is a thread where a diamond was being subtracted from a circle. When the diamond point was placed at the exact center of the circle, the subtract shape would vary between several different point positions. By moving the point a very small amount away from the center, the subtraction worked as expected.
  22. Hi, Goldblacc, Start by going to youtube, and search on "digital painting." A couple hundred tutes and tips will show up, probably a couple hundred hours. And thats just the tip of the iceberg. Most will be specific to a certain application, such as Corel Painter, Krita, etc, etc, etc. There are a few using Affinity Photo and Designer, tho' neither is specifically a painting program. Search on Frankentoon, for some nice examples of what is being done w. Affinity, and how to do it. Expect to start by collecting as many "brushes" as you can, and learning how to make your own. Then make a few hundred strokes, dabs, and washes w. each. Then start experimenting w. blend modes, which are much more varied in digital art than in any traditional media I know about.
  23. Hi, dannac, Perhaps the search failed because you searched on . afpalette and not .afpalette
  24. AFAIK, proprietary code can be licensed if the owner allows. Considering that Rhino (whose company pre-dates even Adobe) is aimed at 3D, and Adobe has almost no presence in that field, I suppose it is mutually useful for there to be some file compatibility.
