![]() If you create a brand new and therefore transparent layer, and you want to write text into it, the pixels around the edges of the letters will be partly in the colour you’ve selected to write in, but partly in the colour of whatever can be seen below the transparent layer. New layers though are created transparent, and once coloured, cuts/deletions will cut transparent holes in them, shown by the grey chequer-board pattern. When you create a new image in Seashore, its initial “background” layer is white, and selecting and deleting an area of this white background won’t do anything. (Click a layer to select, click the box to its left to show.) It’s easy to get confused between “showing” and “selecting” a layer. ![]() Often, if edits don’t seem to be happening, it’s because you’re trying to operate in an unselected layer. Layers can be dragged above and below each other in the left-hand margin. To create a new layer, not surprisingly, click New Layer from the Layer tab. When writing for Kindle, it’s useful to check that the areas in a colour diagram will still be distinct in “black and white” before you’ve finished the whole thing! Click the “selection” tab, then “color effect”, then “convert to grayscale”. Using the magic wand then selecting the inverse from the edit tab can be very useful. I found the Tolerance slider on the left useful, but got away without exploring the Intervals and Modifiers selectors to its right. ![]() That magic wand icon selects for similar colours in a connected lump. Or maybe you just missed the tiny circle □. It might not respond quickly because it needs time to complete the completion. Only then, do whatever pasting from the buffer you need to do.Īnd if you’re using that square lasso selection tool, when completing the boundary and clicking on the tiny circle that marks the completion, try to click on the bottom right of that tiny circle, since aiming for the dead centre doesn’t work so well. Similarly, when you’ve selected an area using the square lasso, and hit Command-c or Command-x, you should immediately click on the square selection tool on the extreme left and then click away from your selection area. If you’ve selected the entire image by clicking Command-a, then after you’ve done your copying and pasting into another window or whatever, you have to drag the box containing the gold-lined grid off slightly to one side, then left click on the area that’s left behind, otherwise you can’t get rid of the universal selection. ![]() If this happens, hold the alt key down instead and it will go back to non-square, and will default properly to non-square for a while. Without shift it’s supposed to default to ‘any rectangle’ but sometimes it defaults to squares even without holding the shift key down. The simple rectangular area selection tool can be made to select only squares by holding down the shift key as you press and drag. When you’ve cut or copied a piece of image from somewhere, and you paste into a Seashore image, it will appear in a gold-lined grid which you can drag, but you must click the Anchor button near the top right to fix it in place just clicking away from that bit, as migrants from Microsoft’s Paint will want to do, won’t be enough. For vertical, horizontal and 45º, it’s alt ctrl instead. You don’t draw straight lines in it by holding the left button down and dragging the other end instead, having selected the pencil tool, you hold down alt shift, left click once, then while still holding shift alt, move and left click elsewhere. Seashore is fine once you’ve got used to its quirks (I stuck to the latest version: 0.5.1):
