GIMP :: How To Remove Selection Area Around Parts That Don't Selected
Nov 6, 2012
When I use the Fuzzy select tool or the select by colour tool, how can I remove the selection area around the parts that I don't want selected. For example. I have red car on a white background which I want to cut and paste to a black background. I select the white background, but although it selects all the white, it also selects other small areas on the car which are a similar colour. If the threshold is lowered too much when I use these select tools then I get a very small white border around the object when I paste it on to a dark surface. So instead of selecting using the default (15) or even less, I have to ramp it up so as the selection is closer to object and does not show the white jagged line. I thought that I could use the other selection tools with the "remove from selected" option selected, but each time I place a rectangle around the selected area that I want ot deselect, it does away with the entire selection area. I just cannot get it sussed.
I want to select part of an image with just one layer. Say I just flattened the image and have to move one part of. I select it with the rectangular select tool. It seems intuitive that I could then just move what I selected, but when I drag the selection, the selection itself moves without moving what is inside the selection.
If I then remember to click the move tool and try to move what's in the selection (seems to work sometimes, maybe when there's multiple layers?) the entire image moves.
The only way I can move part of the image over is if I make a selection and then cut it (ctrl X) then paste it.
How am I supposed to move part of the flattened image, is there a way I can set it to default to "When I select something, I can immediately drag that selected area around."
I presently have code that will select objects on screen based on particular stored object handles. Â The code then prompts the user to add additional selections once these handle selections are made. Â No problem. Â The problem lies with attempting to deselect the objects that were selected via object handles. Â I should say highlighted because that is what the present code is doing. Â It is highlighting the objects on screen. Â The code I am using follows:
Dim ids(1) As ObjectId ids(0) = ObjectIdFromHandle(myDocDB, "1D6") ids(1) = ObjectIdFromHandle(myDocDB, "1DE") Autodesk.AutoCAD.Internal.Utils.SelectObjects(ids) ' Get the Pickfirst selection
The other day I accidentally hit a keystroke combination that produced an effect I was surprised and happy to see. I have not been able to reproduce it.
I had a layer that was smaller than the layer below it, those being the only two layers. And somehow I was able to select the size of the top layer down onto the lower layer in a way that I could move around to position.
THERE I'D LIKE TO ASK ABOUT CUTTING ... SO I'VE DONE THE SCISSORS THING ,CLOSED THE SELECTION AND IT APPEAR IN A FRAME , HOW DO I MOVE SELECTED AREA ? ALSO HOW TO MAKE THE FRAME ITSELF DISAPPEAR ?
I've selected a rectangular area of a jpeg and I want to fill it with a particular colour from another area of same image. Bucket Fill doesn't work here as it only selects from particular colours and shades in forground/background.
I have selected a Layer in Gimp and I have a certain selection inside the Layer.
Now I click on tool "Bucket Fill", Mode=Normal, Fill Type=FG Color Fill, Affacted Area=Fill Whole Selection.
Opacity is 100%
The FG color is black.
But when I click into the selected area it gets filled with a transparent black! When I click again it gets more opaque and after another click its fully opaque black.
But why does Gimp fill the area transparent after I first clicked even though Opacity is 100.0??
In MS Paint when i select part of image with Polygon tool, this part is auto filled with background color. In GIMP i have to use first Selection tool (Free Select) and than switch to Bucket Fill for filling selected area with color. How to make auto filling selected area with color in GIMP as it in MS Paint ?
I want to remove all but a rectangular area from an image. I do not want to make the rest of the image white, I want it to go away. I want to just have the rectangular image pixels left.
To be explicit, I want it to be like I cut up a photo, and threw the outside away.
I was wondering if it is possible to anchor just part of a selection, say just a middle point when you are using the perspective transform tool so that you could stretch a image layer to fit a opening of another layer
I have a drawing that is 720X596 px and I have used the rectangular tool and select - invert, cut out a 222X444 px part that I need to save as a jpeg. However, I can not figure out how to either : delete the 720X596 drawing to leave the 222X444 drawing: or, select the 222X444 drawing to save it.
you've zoomed in to start this painstaking freehand selection withlots and lots of points, and when you get to the end, nothing getsselected. Then you notice that, once again, you had done a Select Allsome time ago (invisible because you zoomed in) and forgotten to SelectNone before clicking the lasso.
What do people do to avoid this? (I know the obvious answer is "rememberto check what your selection is all the time", but that's seriouslyflow-disruptive.)
GIMP could blink the image or something when you add selectionpoints that don't increase/decrease the already selected area, but Iguess that might take some time to implement.
How do I combine a fuzzy selection area with a dodge or burn operation?
The fuzzy select tool is handy for roughly outlining areas of over or under exposure. There must be a way to combine an oddly-shaped fuzzy selection area with a jittery dodging operation. Do I have to turn the fuzzy selection area into a "brush" somehow, in order to "dodge or burn" that area?
For quite some time I've been trying to find the best way to remove a white background from images. I've checked out the sticky thread on this forum and as my image isn't of great quality and because it features quite a lot of white that won't apply.
Recently I found this tutorial which is supposed to work great (as seen in the comments). However, I think that because of a GIMP update that won't apply anymore somehow. I was hoping you guys might know what was causing it.
Everything works well until I get to step 7, where I have to select to Alpha. There it selects just the outlines, but my selection includes inner parts of the image, not just the background. And then after I invert and delete, the white that remains still has transparent parts that show up on the upper layer. So, am I doing something wrong with the Alpha to Selection, is that tutorial updated or is there a better way to remove the background from ie. a logo with just one background colour which isn't of great quality.
How can you do the area takeoff of only the selected faces (red area)?  Right now I have to use the 3rd party software to do something like this. I'm curious if there's a way to do inside Revit?
I used a heart fill pattern of the right 75% of the picture and the left 75% of the picture is selected overlapping the first fill in the background... I want to fill the selected background area with a flame fill pattern where it overlaps the selected portion of the heart pattern as well as the transparent area... 'overlay' looks better but Gimp is FAILING to fill the transparent areas, it ONLY fills the overlapped heart pattern portion of the selected content!!! I even tried filling the transparent area with 'white' then filling the selected area, but it STILL ONLY wants to overlay fill the heart pattern, it STILL leaves the rest alone!!! it doesn't matter if the background is white or transparent, it leaves that alone and ONLY fills the heart pattern area of selected portion of the image!!!
The problem is that if one has defined a selected area in an image, using either selection by color or contiguous selection using the 'magic wand' facility, is possible to copy this selection to the Image Map facility of the image, so as to automatically define a set of coordinates as a polygon that can be used for link purposes? Perhaps there is some interim step that is required, or perhaps a special script is required?
I've created a lisp that draws the boltholes of a pipe flanges, using the correct number of holes, at the correct diameter at the correct bolt-hole diameter and then rotates. Everything works seamlessly, when i do just one flange. But I've discovered that fewuently there will be mulitple times when a user will have to perform the command.
So the idea I had was to do the following:
Select all circles with    (setq CirclesFirst (ssget "X" (list (cons 0 "CIRCLE"))))
Go through the code to create the new circles.
Select all circles with    (setq Circles (ssget "X" (list (cons 0 "CIRCLE"))))
Remove selection set "CirclesFirst" from "Circles".
But what for some reason (command "_.select" Circles "R" CirclesFirst "") does not work.
im using Adobe PS 7.0. Im trying to So I have picture of A person standing in a city with clothes and everything. The thing im trying to do is changeing the color of his jacket (only) but every time I try it changes the color of the whole pictures or something else. Image>Adjustment>HueSaturation>Changeing from master to other color>then pressing ****+ and taking some samples> then when im draging the Hue or saturation its changes the whole picture. I also tried Replacing color but aswell denied.
I want to move and rotate a selection but PS (CS3) gives the message it can't be done because the selected area is empty. However, if I rotate or move in the background layer or a duplicate background layer the whole image changes, I also move or rotate the backgroundstuff while I only wanted to rotate the selection.
I am running autocadlt and opening up a very detailed drawing by an architect which was likely drawn on the most recent version of the autocad. When i go to select a certain area of the plan, elevation views appear in the background as i drag my selection with the mouse. The elevation views are not visible in the plan in the model space. All layers are on and unfrozen.
I am a surveyor and am trying to import the plan into my survey program (which only accepts files in autocad 2007 or earlier anyway). When I open the file in the survey program, for some reason the elevation views are showing and can not be turned off.
I tried to use the command erase, then "all" it tells me "2891 objects found, 19 not in current space". Does that have anything to do with it?
I have gone into the layer manager and selected all the layers and turned them on, and have unfrozen them
I have a little dilemma at the moment. I've spent a good half an hour or more using the Lasso tools to select a bunch area's while in a very high resolution so I can use a filter on certain areas.
Well that filter is bugged for some reason. And I need to restart Photoshop. But when I save it as a PSD. And open it again. My selection is gone and I'm left with my unselected image.
So, Does anyone know how to save your project, while still keeping the selection lines intact?
I'm trying to extrude a flat polygon so that i can break it up into pieces using volumebreaker. When i'm in edit poly and i extrude , this is what happens: url....I want it to be extruded downwards, but leave the selected area on the top.
