![]() Final ¶įinally I’ve added a “Shadows” layer for making the doughnut and the other elements less flat. you can add some shadows over the forehead by painting over these zones. The “Hairs” layer contains … well, what do you think will contain a layer called “Hairs”? Yeah, right answer! P Please notice only that this layer is below the sketch one but over the others, so the extra painted zones of the “Skin” layer are covered by this one. I’ve used it because I want be able to change and retouch the doughnut shading without the white text (that should stay as brighter as possible). The “Details#2” layer is used for some extra details like the white text over the blue doughnut. For first you should fill with the base colour the shapes (use a paint tool), then apply (with the airbrush) darker shades on the edges and brighter ones over the cheeks. ![]() Here I’ve coloured the skin and the shoes with the paint tool and the airbrush. Top of the gimp window shows the number of layers. A layer group can be collapsed - the little arrow on the left of the icon - to keep the clutter down. 221 Septem01:01 PM I have found it Its the eraser tool:) Edit: But it seems like there is no way to Undo my paintings in the alpha layer:/ I can erase the whole alpha layer with the erase tool (thus there is this checkerboard image everywhere). Add layers and paint or drag existing layers into it. Step 3 ¶Ĭreate a “Skin” layer over the “Details” one. An empty layer group (7) will just show the folder icon. Don’t be too afraid of going outside the shapes, in the next steps we will see that some stuff will “disappear”, covered by other layers. As you can see, thanks to the multiply mode, the black lines of the sketch are kept while the white zones are “transparent”. In this example I’ve used it for painting the blue doughnut. Step 2 ¶Ĭreate a new layer and call it “Details”. From now the sketch layer will stay forever over the others. Now turn the mode for the sketch layer into multiply. Step 1 ¶Ĭreate a new image of the wanted size and place below the sketch layer a pure white background layer. It doesn’t necessitate to be truly a black and white image (2 colors), often a well contrasted grayscale image is better (use contrast autosketch or/and the brightness-contrast tools). ![]() ![]() Intention ¶įirst of all you have to acquire through a scanner or something similar your sketch. The eraser removes areas from the layer replacing them with the background color or - if the alpha channel is on - with transparency (see here).įinally, when you remove the alpha channel, GIMP replaces the transparency with the background color (in your example the background color was black).Ĭoming to your question, if you want transparent images with full colors, you can simply use brushes with a 100% of opacity (and, if the case, a hardness of 100).Text and images Copyright (C) 2002 Marco ( LM) Lamberto and may not be used without permission of the author. ![]() If the layer is without alpha channel, the brush's color merge with the background color (or anyhow with the colors of the pixels). You can also call it by clicking the tool icon: in the toolbox. You can find the Bucket Fill tool from the image-menu through: Tools Paint Tools Bucket Fill. On the other hand, you can use on an image (whether with alpha channel or not) brushes with opacity (see here), which create the effect of a color with transparency while drawing. If this option is checked, only the non-transparent parts of the layer will be filled. the browsers) are able to use this information while representing the image. PNG) are able to store the alpha channel information and some applications (e.g. You can find here a simple diagram which illustrates this concept. In GIMP as well in other editors the images can have a specific channel named Alpha channel, so named from a process called alpha compositing, used to create the appearance of partial or full transparency. ![]()
