I am making a game and need to save a image of the screen, so i googled it and found this methode:
pygame.image.save(window, "screenshot.jpeg")
the problem is though, I don't know where it saves it, because it doesnt appear in the same folder as the programm is in for me.
Try using an absolute filepath, like "C:\screenshot.jpeg"

I haven't dabbled with animated gifs for a very long time. I'd like to create something similar to this:
https://dribbble.com/shots/2941889-Wind
I can't imageine whoever created this animated frame-by-frame to get that result. So i'd like to know what tools there are for doing something like that? Or perhaps i'm all wrong and the only way to do it is frame-by-frame?
Just some advice where to get started if anyone is able.
So what i did in the end was use Adobe Illustrator to create the paths.
I then changed the stroke to dashed. Modifying the dash i was able to make it appear as thought the line was growing along the path. I then created more paths.
I then created a js file to incrementally increase the dash and save a gif. This created me over 100 snapshots.
Imported these into Adobe Photoshop and export! Bingo!
I am working with an old system of palletes. When I export an image, it also creates an pallete with 15/16 colors. But when I try to replicate the same result, the program does not recognize the image which I just created. To analyse what happened, I opened some images with notepad and compared them with my "creation" and I noticed quite some differences.
But the most interesting thing was that at the beginning of my images' code was the type "BM6", while they should be "png" or "bmp". I think that is some thing of codification, but I cannot find anything about it.
If the image file is properly formed, then you can take your .bm6 file and simple change / rename the extension to .bmp. And it should suddenly be an image.
.bm6 can result from creating an image file using a text editor, as seen here.
Okay the Title can be misleading.
But it´s like this.
I have made an application that constantly sends Images from Client A to Client B.
When Client B receives the image, it will replace the last image.
I currently use Picturebox or Panel, so pretty much:
panel1.BackgroundImage = Image.FromStream((MemoryStream)NetSerializer.Serializer.Deserialize(tt1.GetStream()));
It looks weird though, but as you can se, it will just change the image, when it´s there.
This all goes well up to about 800x600, then it will bottleneck.
I don´t know the update frequency, but i am guessing it´s around 60fps, as i am taking screenshots from my desktop or particular windows.
The bandwidth is not the problem here as long as i don´t use .bmp at 800x600+ of course.
Anyway, my question is, what can i use to replace this way of showing images?
I am guessing something with Directx/OpenGL or something?
Sadly i haven´t found a way to even display an image with that, though then again, i have a hard time understanding it.
I am open for suggestions and examples.
EDIT:
I am thinking, maybe to use WPF to just show the image.
But i don´t know if i can change the background image from a winform, so if it´s possible then i am all ear.
Thanks
When I use the following,
imshow(imread('image1.jpg'));
imshow(imread('image2.jpg'));
imshow(imread('image3.jpg'));
imshow(imread('image4.jpg'));
imshow(imread('image5.jpg'));
imshow(imread('image6.jpg'));
I got only image named image6.jpg in the output figure.
There is also an option figure,imshow(...); to view all the images each in new window.
But writing figure in each line where I need to view the image is a repeated and tedious process. Is there any other solution to get the same output as with figure,imshow(..);
without using figure function.
I mainly put on this question because while programming a lot somewhere we forget to use the figure function and so the image that we need to view wont be visible. It would have been overwritten by other image. So provide me some solution.
I ask this only for simplicity in writing the code. So if there is any solution, please mention.
Thanks in advance.
I'm not sure, but I don't think that there's a workaround to that. MATLAB basically changes the current figure handle to that of a new image when you use imshow. One thing you can do however is to make a copy of imshow in your local directory and edit it accordingly to make your own UDF.
What I would recommend however (so as to preserve functionality across systems) is that you open your code is an editor and replace all imshows with figure, imshow. This should be easy enough and it'll be easy to revert back as well.
I'm trying to add and if needed by user, change the image from a widget in python.
I'm using Glade with gtk2+, python 2.7.3, and these is what I'm doing
image = gtk.Image()
image.set_from_file("MyImagePath.png")
image.show()
button = App.get_object('buttonExample')
button.add(image)
and this is what I get when try to change the image
GtkWarning: Attempting to add a widget with type GtkImage to a
GtkAspectFrame, but as a GtkBin subclass a GtkAspectFrame can only
contain one widget at a time; it already contains a widget of type
GtkImage
The image is loaded correctly as expected, but if I change the input path for image, I wish I could change the button image, but this is not what I'm getting.
I tried to use gtk.Image.clear(), but it says I cannot use it on a button (maybe im just messing things around)
Is there a good way to load and reload images to a button?
Thx
You either have to remove the old image from the button before adding a new one (the error message is pretty straightforward about this), or you could try changing the current image:
button.get_child().set_from_file("MyImagePath.png")
This was exactly what I needed. I used the clear in the image as you said and also cleaned the button image, as follows:
App.get_object('buttonExample').remove(image)
image.clear()
Thank you very much for you help!
