I have a powerpoint presentation that I will display to an audience.
I want to include a watermark on it when someone attempts to print. This will watermark will only show on the print output and not on the slides itself.
Is there any easy way to do this?

I have a PDF file that consists of the following image:
I used this image in a latex document in overleaf. The original file is 14MB large so it took overleaf some time to load it. Surprisingly, the loading sequence is such a beautiful video that I would like to make a movie out of the layers of this pdf image. I recorded my screen to get a preliminary version of this movie, but you can see that the video is not perfect and especially at the end the video it is quite far from being smooth.
You can find both files (original PDF file of the coils & the video recorded from screen) here: Documents
Is there an easy way to transform the layers of this PDF image into a movie?
I guess the first question is how can I extract the different layers of this PDF image?
Thank you very much in advance,
Jimmy
I need to be able to bulk sort through images that contain a graphic and remove these images from the folder. The graphic is a ruler-like image for scale.
I'm a novice with FFMPEG, but have already written a batch script that resizes images. The logic seems pretty understandable, however my issue is that I don't know what and where to research for a solution to my problem. From what I read, imagemagik might also be a great tool, but I feel more comfortable with FFMPEG.
I expect the script to look through all image files in a folder and find those the contain the ruler graphic and remove the said images with the rule graphic from the folder. The images are product shots on white backgrounds and the rule graphic is not overlaying anything or acting like a watermark.
Ideally, if possible, a way to crop out the graphics would be an amazing next step.
I am using matplotlib to draw a graph using some data and I have saved it in Pdf format.Now I want to add a logo to this file.How can I do this.
Thanks in advance
If you can do it the other way round, it is easier:
plot the image
load the logo from file with, e.g. Image module (PIL)
add the logo with plt.imshow, use the extent keyword to place it correctly
save the image into PDF
(You may even want to plot the logo first, so that it stays in the background.)
Unfortunately, this does not work with vector graphics, but as logos usually are not that large, you may use a .png or even a .jpg.
If you already have the PDF's then this is not a matplotlib or python question. You need some PDF editing tools or libraries to add the logo. Possible, but an entirely different thing.
I downloaded a explosion generator that makes an animated explosion but saves each frame as a seperate png image. I cant for the life of me find a tool that will take all the images and make an animated strip image, with the frames next to each other. I tried gimp but no luck! The Photoshop image combiner is too cumbersome. Any recommended utilites to do this?
Gimp can do this, and it is actually a piece of cake.
Open all the frames as individual images. Then on the first image select Filters|Combine|Film Strip. Add the remaining frames to the list on the right side (in the correct order).
Now click on the Advanced tab and set Image Height all the way to the right (1.000) and Image spacing all the way to the left (0.000).
Hit OK and you should have your filmstrip!
The GIMP film strip works fine but does force a background color on you, if you have images with transparent (alpha) background this might be problematic for you.
I need to build a Poster (8 1/2 by 11) using data entered by the user and pictures and place that poster in the user's media library. It looks like BitmapImage is the mechanism to build either a JPG or PNG image but how do I place text strings and pictures on the image in a grid/form fashion?
TIA,
George
If you need to place things in a grid ina form-style, it might be worth building it up in XAML or in code and then using WriteableBitmap to render it to a bitmap.
You might find the following posts useful to achieve this:
WP7 Screen Capture On-Device
Screen Capture on Windows Phone 7
For an example of combining images and text see how do i add text to image in c# or vb.net
Of course, any image can be printed at any size, it depends on the quality you want.
