I want to select a surface from polydata(STL file) and transform(deform?) it. When you select a surface, it is not connected to the existing polydata or the surface is extracted and a hole is created. Is there a way to solve this?
I want to make it like the picture below.
(The pink color area is what you want to create.)
Image attached
We are going to make some changes, not all of the polydata.
I answered a similar question in the vtkplotter github issues:

I'm looking to composite one image on top of another, but the location and size will be determined by a green box in the original image.
Is this something I can do w/ jimp?
Thanks!

Here's what I'm hoping to do:

Edit: It looks like OpenCV is a great place to start. After some digging, I'm thinking these are the correct steps:
Detect if there is a square with a specific color in the image
Capture the coordinates & dimensions of that square
Create the new image by compositing face.jpg on top of the original image
I'm not quite sure the best path to approach step 1.
The idea is like the inverse of Ishihara test (http://www.colour-blindness.com/colour-blindness-tests/ishihara-colour-test-plates/).
I want to create with GIMP an image that showing something and then if I add a color layer, for exemple green glasses, then I see something new appearing.
I've searching far in Google and so but didn't found anything. Do you know how would I make this?
The Ishihara tests use the principle of combining things color blind persons cannot differentiate.
Coloured glass filters will only remove other colours from what you see. They don't add something. Therefor it is not possible to create a digital image that contains no information unless seen through a colour filter.
The only thing you can do is overlap your "hidden" information with high contrast colour noise.
Like here:
Using the glasses / filter only improves the visibility. The information is not added. It was always there.
I Have an image for a homepage screen. The top part of the image when clicked should lead to the second tab, the left hand side of the image when clicked goes to the third tab and so on.
Basically geotagging an image , so that i can make areas of the image clickable leading to different tabs
I tried implementing using a map chart where i added an image layer, and added this image. Some solutions asked me to add a marker layer with x,y coordinates but I'm unsure on how to proceed on my image
Kindly help with any alternative solution
it sounds like you want an image map. "geo tagging" is when geographic info like latitude and longitude are added to an image.
your best bet is to use a text area with a table filled with image-type action controls. if you have Photoshop, you can use a technique called Image Slicing to prepare your images.
FYI, this is probably not a simple task, especially if you don't know much about HTML. you may want to consider a different navigation scheme.
if you update your question with more detail about the end result you are trying to achieve, maybe someone can share a more fitting solution. http://mywiki.wooledge.org/XyProblem
Can anyone tell me how I would add a label to the center of a polygon by way of kml like the ones in the link: http://maps.huge.info/zip.htm.. I don't want a marker and I don't need the info to pop up when its clicked, I need it to be there from load, it would just have the zip code for the particular polygon. I wont be drawing the entire US zip code, maybe just a few at a time. Oh, and I'm using mapquest API not google or anything else
Use the Leaflet.label plugin, that does exactly this.
My goal is to create something like the arrow from car that indicates the speed of the car. My problem is that I do not know what is the best practice for moving the green arrow. I have an image arrow.png and I guess I need to manipulate with the place that the picture is shown and with the rotation of the image.
Can someone point to me some guidelines ?
My basic idea is to have a relative layout for the background and to have one image view that will change the position, but the part changing position is little unclear to me. And I do not think that is good idea to play with layout params and margins...
I would probably extend ImageView then override your onDraw method and use canvas.rotate() to rotate the arrow depending on your app state.
