I've tried: Using the mouse instead of graphics tablet pen, restarting Krita, changing brushes, using the eraser keyboard shortcut, using the button on the menu bar, and using the button on my pen to select the eraser.
I use Photo iPad V2 Affinity. When I select the eraser and choose the -> simple round pencilmode, only a part is erased (so about 50%). At the same time I have the eraser at 100% opacity (shpild erase all with one move over). I have to erase over it many times until all is erased. If I choose oil pen mode, then everything is erased with one move/100% opacity. Where is the error: in the software? Or in the logic? I can't work like this if I have to erase several times over the spots, despite 100% opacity.
I seem to have lost my Region eraser. When I use the two finger gesture it only erases what is under the pencil nib and in the toolbar I can only change the width of the eraser. I can't see the Region eraser anymore.
I'm sure I used to be able to remove parts of a line for example in the old skitch, but can't find an eraser tool anywhere. I want to make a dashed line, but I can't see an option to create a dashed line, and now I can't find a way to remove parts of a solid line to make it dashed.
Please bring back the eraser! I must not be using Skitch much anymore since I just noticed it's missing, but now I have to look for another tool. I want to be able to use Skitch like a physical notepad--drawing and erasing at will!
Removal of the eraser? What on earth were you thinking? I've just started using Skitch and assumed I was just missing something obvious in not being able to erase anything. It's a fundamental part, and when I'm trying to jot handwritten things alongside images and making a mistake deleting the entire section is not a viable option.
Why does the eraser act like a paintbrush. I'm editing Minecraft textures for a map with custom resource pack and yet when I erase a pixel, it slightly erases any pixels near it, like the paintbrush tool. It's driving me insane, how do I stop it!?!?
I have an drawing app for Android and I am currently trying to add a real eraser to it. Before, I had just used white paint for an eraser, but that won't do anymore since now I allow background colors and images. I do this by having an image view underneath my transparent canvas.
There are several other posts about erasers, but most of them just say to use PorterDuff.Mode.CLEAR, setMakFilter(null) and that that should work. In my case, it doesn't. No matter what I try, I get the black trail first and then the desired result only after I release.
I would like to use my Asus pencil to take handwritten notes on excalidraw. However it is bothersome to the workflow to manually switch to the eraser everytime I have to erase something. Is it possible to assign the button on the pencil to do this like it does on OneNote for example?
Have you tried an office supply store?
Here in the states, many of the large chain office supplies carry a smattering of drafting/drawing supplies. The battery/electric erasers are usually stocked close to the T-squares and circle templates.
It always does this. At least on this file. I made a new project to demonstrate the issue, but the issue did not occur then. I used white pen out of frustration. Am I to expect the eraser to behave as smoothly as the pens do?
University of Delaware biochemist Jeff Mugridge is trying to figure out how so-called mRNA eraser enzymes work in our cells, why those erasers can sometimes misbehave and lead to cancer, and how science can pave the way for possible solutions to this problem.
Mugridge, assistant professor of chemistry and biochemistry, was recently awarded $1,956,466 from the National Institutes of Health (NIH) to study specific enzymes that can act like erasers and remove critical chemical groups, called methyl groups, found on mRNA molecules.
Along with two doctoral students working in his lab, Mugridge is specifically looking at a class of eraser enzymes called RNA demethylases. Demethylases remove methyl groups on RNA that play important roles in gene expression and the progression of cancers like glioblastoma or acute myeloid leukemia.
Scientists have recently identified a few RNA methyl modification erasers, which has raised the intriguing possibility that these methyl groups can be both written and erased from an mRNA transcript, Mugridge said. But how these eraser enzymes recognize and choose which specific methyl groups to remove out of the thousands that are found on RNA, and how frequently they do this, remains poorly understood.
For instance, in glioblastoma an eraser enzyme known as FTO is overexpressed, meaning the glioblastoma cells make much more of it compared to normal cells. This leads to a lot of methyl-erasing activity on RNA in those cancer cells, which seems to be important for cancer progression. Research has shown that when FTO is inhibited with a drug, it slows down cancer progression in glioblastoma. However, therapeutics that can selectively and effectively target RNA demethylase enzymes to treat cancers have eluded scientists.
If Mugridge and his team can figure out the molecular details of how these demethylase enzymes work and how the cell controls their functions, they could look for ways to manipulate which methyl groups get erased from RNA and pave the way for therapeutics that help correct misbehaving eraser enzymes in disease.
In Brown Laboratory, Mugridge and his students produce proteins in bacterial cells and then purify and isolate the specific RNA demethylases of interest. Brittany Shimanski, a doctoral student from the Chemistry-Biology Interface program, is using these purified enzymes to conduct biochemistry and structural biology studies to better understand how the eraser enzymes function and select their targets.
