I am trying to fill a designed image in Photoshop. It currently has a greyer-white coloring and I need to change it to pure white to help it coordinate with a landing page design. I know how to select most of the design with the Quick Selection Tool, but when I go to fill it I am not sure if I am doing it right. I also cannot select the whole design with the Selection tool. When I go to unselect the part that I filled and select another piece of it I cannot get it to unselect the first piece of the design.

I know this is pretty simple, I am just stuck. Any Photoshop advice on what I am doing wrong or another way to accomplish this would be much appreciated.

Hi, I have an application running in windows 2000. I do not have the source code for that..Moreover, it is mandatory for me to run this .exe in windows 2000. I have attached the jpeg file of the gui. This gui consists of different slots where I can manually type voltages.

Coming to my problem,
However, I want this to be automated..I want to type these voltages hundreds of times and very fast. Thus, lets suppose I got these voltages from another program in to a text file.
 After assuming that I have a set of voltages in a text file.. Now i want to access this program, then copy a number from the text file, then paste in the program slot, then a double tab and copy and paste the next voltage. This process needs to be automated.. I have no clue what to do.. I was searching and found bat file or JAVA or .net can be used (just a superficial surfing the internet)... What platform should i choose for this program. Any help is greatly appreciated and acknowledged...Thanking u in advance
How do I build a page that retrieves a the URL (using LINQ) and display that in the page.

I have parameter that I can pass in Request.QueryString("MyParam") and using this I can get the URL out:
Dim db As New DatabaseDataContext
Dim MyParam As String = Request.QueryString("MyParam")
Dim MyURL As myTable = (From x In db.myTable Where x.field = MyParam).FirstOrDefault

Open in new window

Now that I have the URL I will need to fetch it and display this. The Images are NOT in the ~Image folder (outside application folder).
These images are of file types "TIFF".

I have used the Image control and various solution from the web but could not really make it work.

What is the correct method to achieve this? May be I need to use some other control?

Your help will be appreciated.

Hey all I have this image here that's 489x508:


and the box where I need to put that image is sized 400x300:


So I resize the image to 0, 300 so the height matches the box height (which is not correct):


Then I try to add the second image on top of that one (again, did not come out correct):


But what I am wanting to do is fill in the exposed background area(s) that are just a plan color (which is white in this example) with the original image with it blurred like so:


What would be the code below need modified in order to do that using the C#?

My code:
    stream = getPic.OpenRead(new Uri(@"C:\Users\David\Pictures\YnTf9.png"));
    Bitmap bitmap1 = new Bitmap(stream);
    stream = getPic.OpenRead(new Uri(@"C:\Users\David\Pictures\YnTf9.png"));
    Bitmap bitmap2 = new Bitmap(stream);
    using (MagickImageCollection images = new MagickImageCollection())
         // Add the first image
         MagickImage first = new MagickImage(bitmap1);
         first.Crop(400, 300);
         first.Blur(0, 10);
         // Add the second image
         MagickImage second = new MagickImage(bitmap2);
         second.Crop(0, 300, Gravity.Center);
         // …
PaperPort XP Compatibility Mode

Joe thank you for your input. I have gone over the I formation in your article and preformed the suggested steps. Unfortunately this did not change anything. Paperport is still giving the comparability error. The one thing that is different in my registry and do not know why is part of one key is missing \Layers

HKEY_LOCAL_MACHINE\Software\Wow6432Node\Microsoft\Windows NT\Current Version\AppCompatFlags

I did not remove this and do not know how to get it back.

I have been using paperport 14.5 for quite some time and the compatibility error suddenly appeared out of the blue.

Any help would be appreciated.

Hi Jerry,
We now have this same discussion going on in three different places...this article, my Patch1 article, and your question.

I suggest that we consolidate the three threads at your question:

See you there! Regards, Joe

Can't print Photos in JPG format. This issue began two weeks ago. My printer is a Toshiba eStudio 355. My PC operating system is Windows -10

A client of mine on a Mac has mistakenly deleted some photos and then emptied his trash.
Is it possible to recover those photos? I think his marriage depends on it.
After backing up macOS 10.11.3 -  .MOV files will not play. Backup was with Acronis 2018 to local HD.

OS reports "Cannot Play Video" Photos cannot play this video because it uses an unsupported format."

The OS was not restored, only backed up. macOS reported after backup - had to 'Restore' photo library

Other format files (e.g. .mp4) play OK. .MOV files OK on my iPhone iOS 11.2.6

How can I ?? these .MOV files to play?
Hey all I have the following image box' sizes on my WPF form:
 Box |Width |Height
 1   |357   |272
 2   |357   |272
 3   |365   |460
 4   |365   |265
 5   |715   |455
 6   |360   |465
 7   |360   |465
 8   |360   |465
 9   |540   |290
 10  |540   |290

Open in new window

So visually it would look something like this:
 |       |        |       |
 |   1   |    2   |       |
 |----------------|   3   |
 |                |       |
 |                |-------|
 |       5        |       |
 |                |   4   |
 |        |       |       |
 |   6    |   7   |   8   |
 |        |       |       |
 |            |           |
 |     9      |     10    |

So what my goal is is to get the current image I am wanting to place into a box and get its width and height and from that determine the best box to place it in so that it will show the image:

- Without black borders on either the left/right or top/bottom (or both).
- Not chop off the important areas of the image (mostly the middle section moving out).

I have decided to use Magick.NET in order to ease the pain of doing something like this from scratch. So when I determine what box I will be placing the image into then I can use the Magick.NET to crop it using:

Resize with something like this:
imgStream.Crop(width, height, Gravity.Center);

Open in new window

MagickGeometry size = new MagickGeometry(width, height);
size.IgnoreAspectRatio = maintainAspectRatio;
// Adjust geometry offset to center of image (same as `-gravity Center`)
size.Y = imgStream.Height / 2 - height / 2;
size.X = imgStream.Width / 2 - width / 2;

Open in new window

So to sum up the above - I am in need of finding the best box to place the image into before I go and use Magick.NET on it.

What is rough cost per page to print with this printer:

For color

and for Black and white?

I just paid up to $1.79 pp at a copy shop I will not mention and NEED another solution.

 I need a portable color laser and might as well make it all-in-one.

Any better options?

What are some utilities or methods that I can use to reduce the size of screenshots & pictures within Windows programs?

I often take screenshots, use the snipping tool, or have graphs or pictures that I then paste into Word documents. These items take too much space and I need to reduce how much size they take on the page.

How can this be done?
Getting the most out of my iPhone 7 camera

I go on a site seeing trip and expect to take photos from big open spaces, with distant famous buildings. I no longer have a camera that zooms with a great lens.

But I have an iPhone 7

How do I max out the resolution of the camera? I assume the pics will be vary large, but could prove very interesting when I zoom in with my image editor on my Mac.



We have a graphics designer who is using Macbook pro laptop.

She stores all her photos from her iPhone (because she takes a ton) in the Photos app.

The photos app currently has photos going back 5 years and it is filling up space on her hard drive of the laptop.

Can someone recommend a solid solution to archive her photos from the Photos app?

Here are the requirements in the order of priority.

1. Easiest way to export/archive so a normal user can do it.
2. Preferably cloud destination but export to external HDD should be fine.
3. The exported/archived data should be readable from anywhere i.e. even from a PC.
4. Import back at a later date should work properly in the sense that the imported photos should appear as they did before they were exported/archived.

Ask any questions if you need more information on the environment.
We have an Exchange 2013 DAG and we recently started not allowing users to change their own photos.  All user photos have been uploaded into AD using the thumbnailPhoto attribute.  The trouble is, previous to this, some people deleted their photos and some changed them to something other than their face.

Right now we're in a situation where the right photo is stored in AD but users who've changed or deleted their photos in the past aren't showing.  All other users' photos are showing fine.  I'm looking for a way to have Exchange show the latest photos from AD for the users who've modified them in the past.
On my ms/access app I have an OLE field that must store images. The images are seen on an image control. The question is how do I move the picture in the image control to the OLE field?
