#Gimp transparent background move to layer professional
This is the method that requires the most skill and takes the most time, but it’s also the best method of using GIMP to delete background to transparent in my opinion because it produces the cleanest, most professional result. If it’s easier for you to create a selection from your foreground/subject instead, go ahead and do so, then just go to Select > Clear before deleting the selection. Once you’d created a selection from your background, press Delete on your keyboard, or go to Edit > Clear if you’re using Mac. You can also select additional shades of the same color by holding Shift and clicking on them as well.
You can increase the size of the selection by clicking and dragging to the right, or decrease it by clicking and dragging to the left. Grab the Select By Color tool by clicking on the icon highlighted above, or by simply pressing Shift + O on your keyboard.Īs previously mentioned, simply click on a segment of the image that contains the color you’d like to delete. This tool works great if you have an image where your background consists of just a single color and maybe a few different shades of it. Once you click on a specific pixel with this tool, it will create a selection around it and every other pixel with the same color. Method 2: Select By Color ToolĪn even simpler method - similar to the Fuzzy Select Tool - is the Select By Color tool. Nothing will change visibly on the screen when you do this, but what happened is you inverted the selection so that you now have the background selected and not the foreground. Once you’ve done that, simply press Delete. Since you want to delete the background and not the subject, simply go to Select > Invert. If you created the selection by clicking on your subject, you’ll only have your subject selected. If you created the selection by clicking on the background, simply press Delete on your keyboard (or go to Edit > Clear if using Mac) and you will have successfully used GIMP to delete your image’s background to transparent. This will create a dotted outline around your subject known as a selection. You can add to your selection by holding Shift and clicking on another area, and you can remove unwanted selections by holding Control and clicking on them.
Drag the cursor to the right to increase the size of the selection and to the left to decrease it. With the tool selected, click and drag on your subject to create a selection. I'll probably try taking out some frames and see if I can get the size down that way.Grab the Fuzzy Select Tool by clicking on the icon highlighted in the above image, or simply press U on your keyboard. I thought I'd done this before (a year or two ago) but must have misremembered the circumstance. I assume you know that you need to add an alpha channel (Layer > Transparency > Add Alpha Channel) to create transparency.as I wrote in # 3 and expand here: I had a misunderstanding of how it worked and thought that there was a way to use one frame as a background for all the other frames (each of which have transparent elements), this being done so because without this approach the gif is too big.

GIMP's differencing engine will then determine which pixels can be made transparent and which must change from frame to frame. I make these by stacking the opaque frames up as layers then saving as a GIF. In comparison, it's harder to ignore the repetition of the motion of Nodame's hair in the fourth animation. If you only saw Chizuko's hair and the flames, you be more apt to notice that the animation repeats the same sequence of frames endlessly. We don't really notice the transition back to the beginning of the sequence so the image looks to be seamless. The third example demonstrates how our minds create the illusion of continous motion. The main thing that differentiates the "background" frame in this case is that it remains on-screen for a longer period of time. The second is more complex because each frame is substantially different from the preceding one. The rest of the sequence is differenced against that. In the first one, there's only one opaque background frame. Here are a few examples that you can examine in GIMP using the Layers window: The differencing engine should preserve the initial white background and make a sequence of differenced layers that are largely transparent. You need to stack the sequence of opaque images, then tell GIMP to save as a GIF. I suspect you didn't do the differencing properly. The problem with your spinning image is that the white background is only in one frame.
