gfx | maintenance mode ] A low-overhead Vulkan | GPU library

I have a quantity of folders with archive files, Parent folder with subfolder eg

Graphics:

• graphics 01012021/file31241.7z
• graphics 01022021/file4231.7z
• odds and ends 01032022/filejohnny.7z

etc each folder contains an archive - various names numbers. each archives contains various files, pdf's txt files invoices and image files. Generally the images are .jpg named various names.

What I would like to do is batch attack the parent folder to extract an image file/s from the each archive from each sub directory and leave the image in the subdirectory with the archive where it came from. If the archive has multiple images that's fine, I am not targeting a single particular image.

hopefully ending up with something like

Graphics:

• graphics 01012021/ file31241.7z yellowstone.jpg flintstone.jpg
• graphics 01022021/ file4231.7z martha.jpg
• odds and ends 01032022/ filejohnny.7z artemis.jpg French toast.png

I would rather avoid if possible extracting all the files separating the images then having to re archive.

What I tried to discover originally was to batch extract the image files to the directory it belongs to, have the image file renamed to its directory name. I didn't get close with a solution, so I think if possible just extracting the image would be fine and I can use a renaming app to do the other I've found bulk rename utility to be just fine once I got my head around it. You wouldn't think that over the years you would collect so many archives, like small drops they ended up become an ocean full.

I have tried researching stack and seen a lot of examples of how eg 7zip works but I just cant get my head quite around it.

I am due to retire they tell me 65 is the time for the chicken coop, I've been a pencil pusher and mouse skater most of my life in the gfx industry. I used to know what was in each archive but memory is a little how to say... rusty nowadays, I know all my archives have images in them. My life would be a lot easier in the sunset of it to look at the pictures and not have to rack my brains trying to remember what was in the archive itself.

Cheers and ty in advance from the colonies downunder.

How to create a grid of images using bootstrap?

Thats what i got when i try the next codes

I'm making a very simple animation using JavaFX. My goal here is just to have a rectangle move smoothly across the window.

I'm trying to achieve this using AnimationTimer, which seems fit for the task. I've tried different ways of rendering, such as a Rectangle in an AnchorPane, or simply drawing onto a Canvas, but in the end it always boils down to the same thing, with the same results.

I basically store the position of my rectangle, and apply a moving rate to it at each frame.

In fact, when I use a constant moving rate in the handle method of my AnimationTimer, animation is perfectly smooth. However, there are 2 problems with this technique:

1. Frame rate seems to be platform-dependent, with no easy way to control it. So the animation would render differently on different machines.
2. Frame rate sometimes varies, for instance when resizing the window, it can sometimes drop by half, or sometimes even double up, which changes the animation speed accordingly.

So I tried to make the animation time-based, by using the argument of AnimationTimer.handle(long now). It solved the inconsistency issues, but the animation is now jittery! A few times per second, the rectangle seems to "jump" a few pixels ahead and then stall for a frame or two to recover it's expected position. It becomes more and more obvious as I increase the speed.

Here's the relevant piece of code (simplified):

GOAL

To open an existing PDF file with multiple pages and add background image to all pages. (Optionally the background image of the first page differs from the others)

In my current implementation (I use .NET 6 and PDFsharp btw.) I add the image to each page, which increases the size of the file dependent on the number of pages.

QUESTION

Is there a way in PDFsharp/MigraDoc to embed a background image only once into the document and then reference it for each page?

CODE

Both PDF document and the image come from a database as byte arrays.

How can I conditionally apply value to the data variable based on props, the ternary operator is generating error, I would like to refer to this code:

I'm trying to write a program which will find all the lines containing the XML tag properties "name", "top" and "left" and will write value of this properties in console.

This is what I got so far:

I have trouble including and linking SDL_ttf and SDL_image to my project. I have a cmake file that works only for SDL and SDL_gfx on Clion. I guess the problem is from the cmake file. I got several errors when I build the project: undefined reference to `FUNCTION'

I'm trying to create a webpage that has news items in a way that it has news image, image overlay, headline and text all in top of each other. However with my code, if I try to continue to create next news below copying everything, it will stack in top of the first news. So how can I get the next similar "News2" image+image+headline+text combo appear under the "News1" instead of overlapping?

I could use "top: xxx px;" to force News2 items down, but it seems like a bad solution when there will be lots of news items in a page.

So I read that run function from Runnable interface is automatically called but it is not working for me (run is not being called). This is my first time doing anything in java so I might have done something stupid. The following code is supposed to move a rectangle across the screen. The rectangle is drawn but it is not moving.

Main:
