Is there a way to manually scroll a large image in PowerPoint? - image

Preview of what I'm looking for
Hello, I'm looking for a way to manually scroll a large image in PowerPoint. In the image there's an example of what I'm looking for. I want to have a preview of the image that I can scroll through and the actual image that moves accordingly to the scrollbar.
Thanks!

I assume you want this in SlideShowView? For sure this can be achieved only by scripting. Essentially you would have to program buttons for up and down movements and use vba do apply this to the image. The preview is a bit more complicated since you would have to do some math too to achieve the conversion in the size differences. All in all a job for a programmer. Are you looking for programming support here?

Simple crop in filepond

I'm trying to add a simple fixed ratio cropping functionality to the filepond input. (meaning that user will be able to drag crop rectangle and choose how to crop exactly)
After reading documentation, I got an impression that it's only possible by bringing full-fledged external image editor (Pintura, which was probably renamed from Doka).
Pintura seems to be a commercial only editor.
So do I understand correctly – there is no way to implement simple crop with filepond without using commercial Pintura editor?
If no, how could I achieve that? My understanding is that allowing user to crop image is fairly common operation and should be out of the box.
Any docs I missed?

transparencize a background image on Photoshop

I would like to use this background image on different pages of my website.
The idea is to have a different color, instead of being grey. I am trying to change the color on Photoshop, and found this topic: https://graphicdesign.stackexchange.com/questions/4056/replace-black-background-with-a-transparent-background but the result is not the one I was expecting.
Anyone knows how to do this ?
yes, you can change it with Photoshop.
Follow these easy steps:
1. Go to main navigation - Images -> Adjustments -> Hue/Saturation...
You must select "Colorize", then you can play with the Hue to find your color and with the saturation to saturate it.
Enjoy! :)
I think this should be in Graphic Design rather than on Stack Overflow, unless you're looking for someway to do it with Photoshop scripting.
If you're looking for simply changing the shade from gray to say orange or green. I would select the layer then go to Image>Adjustments and play around with Hue/Saturation. Play around with that. There may be another way to do it but that's what I would do.

Sophisticated HTML5 Image Map?

I have an image of a living room, which I'm turning into a menu for a new site I'm working on. The idea is that you can click on certain items in the room, like a chair, desk, couch, etc and get taken to the desired page. I'm wondering if there is a clever way of doing this. Since the items are not simple shapes, I don't want to use a standard image map.
Thanks for you help!
I'm answering because a Google search brought me here...
Because you asked for a tool:
GIMP Has a really good Image map creation function.
Open your image in GIMP and select Filters > Web > ImageMap
From there you can create image maps by drawing on the image. Saving will generate HTML you can then tailor to your needs.
This tool looks to be a solid image mapper: http://www.image-maps.com/
I'd suggest doing this with a canvas and SVG's, it would make this quite a bit easier, and more professional.
As Korvin mentioned, doing this in SVG is probably the easiest option, because you can attach events to objects in SVG rather than having to manually specify a particular area in which to listen for events.
If you go this route, I recommend using the RaphaelJS library which has a nice syntax and the advantage of working in IE pre version 9. Here's a demo which, although it uses onmouseover instead of onclick, it might be close to what you're trying to achieve:

Drawing large images for ipad

I am developing an application for viewing images.
I used the example of PhotoScroller Apple to implement this application.
In my application I want to be able to draw on the image.
I had the idea to put a UIView on top with transparent background and draw the lines via touch events. This solution has become very slow because the generated images are very large, around 3700x2000 pixels.
I also tried a solution with the example of Apple GLPaint that uses OpenGL, but it has a size limitation of 2048x2048 pixels.
Anyone have any idea or example of how I implement this?
I think you should try and tile your image.
One option is using CATiledLayer. Have a look at this short tutorial.
Or you could try and use CGContextDrawTiledImage to get your stuff done. Possibly this post from S.O. could help you getting started.

How to easily crop the same image multiple times

I have a set of really big images out of which I need to crop little snippets. These snippets are all exactly the same size but don't follow a strict pattern so I can't do this programatically.
Ideally I would like to open up one of the big files and be able to point and click on say, the top left corner of a snippet and have that automatically be saved to disk without even having to enter a file name, and then continue on with the rest. (Of course this would be the ideal way which I know is probably way off the real possible way!).
I started doing this in Photoshop CS4 but cropping a snippet, saving, undoing (to get to the full image), and starting over again takes way too long.
Maybe someone has a better way to do this in photoshop or in some other software.
Thanks for reading!
Instead of cropping and undoing, you could:
make (or resize) a selection
copy the selection to a new image
save the image
close the image
You might need to split it into two actions, I don't know enough about programming Photoshop.
Thank you everyone for your input.
I ended up doing this with a suggestion a colleague of mine came up with. It consisted of creating a Photoshop "slice" over the first region I wanted to crop and then cloning that region over the rest of the other sections. After that, using Save For Web (and ofter hitting Continue when PS complained about how that image was way beyond Save For Web's capabilities) I could save all images at once.
This was the fastest and easiest method I could find. Until then I was going with Mark Ransom's method.
