Gerai, viskas gerai: užstrigote. Bandote paveikslėlyje panaudoti vieną iš įrankių, tačiau niekas nevyksta, ir viskas, ką darote, nieko nekeičia. Jums pradeda gniaužtis kumsčiai ir kaisti veidas. Ar būsite priversti priverstinai nutraukti programą ir prarasti visą savo darbą? Tai užknisa!
Well, hold on a second. This happens pretty frequently, even to people who've used GIMP for a long time, but generally the cause is not so hard to figure out (and fix) if you know where to look. Lets be calm, and go through a checklist that will probably get you GIMPing happily again.
How to tell: If there is a floating selection, many actions are impossible until the floating section is anchored. To check, look at the Layers dialog (making sure it's set to the image you're working on) and see whether the top layer is called „Floating Selection“.
Kaip išspręsti: pritvirtinkite plaukiojantį pažymėjimą arba konvertuokite jį į įprastą (ne plaukiojantį) sluoksnį. Jei reikia pagalbos kaip tai padaryti, žiūrėkite sekciją Plaukiojantys pažymėjimai.
Pav. 4.2. Pažymėjimo nerodymo išsprendimo meniu
Įsitikinkite, kad pažymėta meniu Peržiūra esanti parinktis „Rodyti pažymėjimą“.
How to tell: If this is the problem, merely reading this will already have made you realize it, probably, but to explain in any case: sometimes the flickering line that outlines the selection is annoying because it makes it hard to see important details of the image, so GIMP gives you the option of hiding the selection, by unchecking in the menu. It is easy to forget that you have done this, though.
Kaip tai išpręsti: jei tai jums nieko nesako, tai ne problema, o jei sako, tikriausiai žinote kaip tai pataisyti, kadangi tai neatsitinka, nebent jūs aiškiai tai padarote; bet kuriuo atveju: atverkite paveikslėlio meniu ir, jei parinktis yra nepažymėta, pažymėkite ją.
How to fix: If doing this has destroyed a selection that you wanted to keep, hit Ctrl+Z (undo) a couple of times to restore it, and then we'll figure out what the problem is. There are a couple of possibilities. If you couldn't see any selection, there may have been a very tiny one, or even one that contained no pixels. If this was the case, it surely is not a selection that you wanted to keep, so why have you gotten this far in the first place? If you can see a selection but thought you were inside it, it might be inverted from what you think. The easiest way to tell is to hit the Quick Mask button: the selected area will be clear and the unselected area will be masked. If this was the problem, then you can solve it by toggling Quick Mask off and choosing Invert in the menu.
Pav. 4.4. Sutvarkyti sluoksnio nematomumą
Sluoksnių dialogas su išjungtu aktyvaus sluoksnio matomumu.
How to tell: The Layers dialog gives you ability to toggle the visibility of each layer on or off. Look at the Layers dialog, and see if the layer you are trying to act on is active (i.e., darkened) and has an eye symbol to the left of it. If not, this is your problem.
How to fix: If your intended target layer is not active, click on it in the Layers dialog to activate it. (If none of the layers are active, the active drawable might be a channel -- you can look at the Channels tab in the Layers dialog to see. This does not change the solution, though.) If the eye symbol does not appear, click in the Layers dialog at the left edge to toggle it: this should make the layer visible. See the Help section for the Layers Dialog if you need more help.
Pav. 4.5. Sutvarkyti sluoksnio permatomumą
Sluoksnių dialogas su aktyvaus sluoksnio nepermatomumu, nustatytu į nulį.
How to tell: When the opacity is set 0 on the layer, you cannot see anything which you draw on it. Look the Opacity slider, and see which side the slider placed at. If it is at the leftmost side, that is your problem.
Kaip tai pataisyti: perkelkite slankiklį.
How to tell: In GIMP, layers don't need to have the same dimensions as the image: they can be larger or smaller. If you try to paint outside the borders of a layer, nothing happens. To see if this is happening, look for a black-and-yellow dashed rectangle that does not enclose the area you're trying to draw at.
Kaip tai pataisyti: reikia padidinti sluoksnį. Sluoksnių meniu viršuje yra dvi komandos, kurios leis tai padaryti: „Sluoksnio dydį prilyginti paveikslėlio dydžiui“, kuri nustato sluoksnio ribas tai, kad jos atitiktų paveikslėlio ribas; ir „Nustatyti sluoksnio ribų dydį“, atverianti dialogą, leidžiantį nurodyti bet kokius norimus sluoksnio matmenis.
How to tell:GIMP can handle three different color modes: RGB(A), Indexed and Grayscale. The indexed colormode uses a colormap, where all used colors on the image are indexed. The color picker in GIMP however, let you choose RGB colors. That means, if you try to paint with a different color than it is indexed in the colormap, you end up in very undetermined results (e.g. it paints with the wrong color or you can't paint).
Kaip tai pataisyti: piešdami paveikslėliuose visada naudokite RGB spalvų veikseną. Meniu elemente Veiksena galite patikrinti ir pasirinkti kitą spalvų veikseną.
