GIMP :: How To Erase Or Change Dotted Areas
Feb 28, 2012
I've got a problem editing an image with a dotted background in it. By 'dotted', I mean an array of small evenly spaced black dots on a white background.
I've tried the fuzzy select tool which kind of works. It fills in the white space with the color I want but leaves the dots untouched. I want to get rid of the dots.
The image has a lot of rectangles containing text (these are not dotted) on this dotted background so using the select tool would be a real chore.

In the image below I have an aerial photo of an Island. I need to make it so as water areas are black and land areas are white (not greyscale) almost like a silhouette. My first plan was to draw round the island with a black paint brush and then use the "bucket fill" with a suitable threshold to fill all of the areas up to the black outline with black, however this doesn't work as the bucket fill either breaks through the black line or when I reduce the threshold, doesn't color the water areas solidly.

This has *got* to be simple - the eraser leaves everything untouched. I have tried tweaking all the settings to no avail.

I am having trouble getting the erase tool to erase part of an elipse shape in Corel Draw. I select the erase tool and click and drag across the part of an elipse that I want to get rid of (so far so good), then I release the mouse and an outline of the nib tool is left behind.

I have an object with a complete white background. I am trying to mask out the white or erase it so I can make it a PNG with transparent background.

I loaded one PNG pic.
I added an alpha channel to make it a transparency.
I used the select by color tool.
I clicked white & removed.
I saved. I switched to eraser - but it is acting like I'm trying to erase something off the transparency layer and won't erase anything.
I have the correct layer selected in the layers window.

I have a square image where I want to erase everything left of a line from bottom left corner to top right corner, so it will be transparent. How's that done easiest?

Wblock when run from the command line used to erase the entities selected, now it seems it does not, but the dialog box shows an option to keep or erase the selected entities.
Any variable name that controls this functionality?

How, after changing a photo to B&W, to color back in a section to the original colors, but can I change those colors to a different color? Like if I wanted to change a hat from red to green.

I have been trying to use the color select/erase feature in Xara P&GD9 (version 9.1.1.28178) on my Windows 7 64-bit computer. I can use this feature to change the appearance of the sky in a photo -- for example, to change it from something drab to an attractive blue. I've now tried to do this in several versions of two photos, and I've been completely unsuccessful. Following the instructions, I first used the color select/erase tool and clicked on the sky in several places to erase it. I then clicked on the Make Soft Mask button and saw that everything but the sky was now pink. I then went to Enhance in the Photo Tool and selected the Hue control. But no matter where or how much I changed the Hue and/or the strength, nothing happened. I was left with the same drab sky I started with. I've tried to show what I've done with four thumbnails.

I've been trying to use the Eraser Tool to erase a background sky and it won't erase. The Alpha Channel is turned on, the Selection Tools work, but the eraser does nothing.

what I'm doing right now is trying to erase the background of many different photos and combine them (as different layers) into one image. I finished two layers and just as I was about get going on my third layer, I made a mistake and did something to the threshold. I didn't remember what I had it on (well, it was on the default setting) so i put it back to 141 and decided to continue with my work. but then I realized that I couldn't select anything.

How can I use the bucket-fill option to fill an area surrounded by a dottedline?
The dotted line is a path; so if I use a line for the dots, the bucket-fillworks.
But how can I step back after filling to change the path's line into dotsagain?

I have a dwg that I need to change the colour of certain areas, they are a mix of blocks and blocks with attributes, if I explode them all the attributes turn into text I have tried a few ways but apart from clicking on everything and doing it one by one I cant seem to do it, is there a quicker way,I have attached the dwg and everything outside of the magenta box needs to be grey while keeping the colour under the box. The file is 5.5 mb and wont upload

Is there any way I can erase the same exact point on multiple layers with one click of the eraser, rather than doing it on each layer individually (and having to line up that same point again)?

I am trying to add dotted pairs to a list of dotted pairs one at a time in a loop, but I cannot get through one iteration.
The pseudo code is basically
(while (/= nil readline) (if = 0 count (setq 0list (cons 8 readline f))
(count = count + 1) (else (setq 0list (append 0list (cons 8 readline f)))
(count = count + 1)
)
)
The program gets the layer name from a text file and makes a dotted pair out it. When it iterates for the first time it puts the dotted pair into 0list. When it iterates the second time I want it to take the next line make a dotted pair and append 0list.
I keep getting error:bad list and I am assuming it is because it is trying to append 0list which only has one dotted pair in it and is technically not a list. I am not sure.
I have like three different versions of the same code I have tried. Any way to read a layer name from a file make a dotted pair and add the dotted pairs to a list of dotted pairs one at a time that would be amazing.
I get the reading and making a dotted pair part. I just can't get the dotted pairs to add to a master list.

I know how to use the scissor tool to cut out patches but since they're difficult to place i like to define areas like with the wand tool. Did i by chance miss a important function?

I've used GIMP to great effect for quite a while now but I know I'm taking the long way around on a lot of things because I'm not very savvy on CG stuff, so I thought I'd ask here. I actually was registered with Gimptalk but it appears to be gone? Anyway...
I am currently making my own 'original artwork' by using usually open source/public domain photos and such, and using transparent layers to "draw" lines over them, making my own lineart. My problem is that I can't seen to find a "turn antialising off" checkbox in GIMP.
Even if I did, I do some postprocessing in Inkscape to turn the lineart into something more smooth, and then it re-antialiases (is that even a word) the picture, and when I try to use the paintbucket to fill in the lineart to get simple color pictures, I get lots of white specks and dots from the antialiased edges of the smooth lines.
What do I need to do to a picture to make sure I can fill spaces with a color right up to the lines, AFTER it has been antialiased, in my example? I can't use duotone or index to 2bit color or whatever, because that bites chunks out of the black lines and also destroys the smoothness of the Inkscape processing, but even if I haven't used that, it still reduces the lines spottily.
I've tried turning the tolerance way up and filling the areas with white first, hoping the white and the near-white specks will be close enough to "bleed" together so I have one color, and then paint with the desired color, but it still has specks.
Also, how to do lineart to achieve the same results I'm trying to achieve. I'm hand-tracing over the lines by eye, which, though I'm good at it and it doesn't take long, is more time consuming than it probably should be, and tedious.

In Elements 6, every time we try to change bright white areas to another color, it doesn't work.
No matter what color is picked, the result is always an area of dark, charcoal gray.
Evidently, the program does not recognize Bright White as a color.
Is there a way to make these changes using this program?

Say you select all of the patterns on one half of the image.
Is it possible to mirror the selection, so that it selects the corresponding ares on the other half as well? Because it would cut down the workload by a fair bit.

I've got a few pictures taken at night of buildings and the street lights and lights on the buildings have come out extremely bright and 'bleed' out of their point of origin (not sure how else to explain it).
All I want to do is to darken these areas without affecting any of the other parts of the image. Is this possible at all?
What would be ideal would be if there was a tool, plug-in or method where I could select a certain colour range or brightness threshold that I could then lower however much I want without affecting the already dark areas.

I am in the process of adding lighting effects to one of my images. I'm trying to get a lightning effect, and decided to use Supernova off of the image's frame. This worked for full-frame layers, but on smaller layers, not so well.
What's happening is that I'm trying to get single objects in layers to have a lighting effect, but it's lighting up the transparent space around them, making a distinctly brighter area... well, it's better if I show you:
Base:
Adding the Effect:
The Unsatisfactory Result:
How to merge two or more specific layers together, that'd be fantastic.

I'm trying to rotate an image. Actually, I figured out how to rotate it. But I can't figure out how to fill in the "empty" triangular areas that represent the area between the edges of the original image and the horizontal and vertical edges of the canvas. I would like to fill these spaces so it is not obvious that the image was rotated. How can I do this?
What is the standard way to manipulate images in this manner?
I've attached a sample image that I rotated.
