How to decrease image size in photoshop

To decrease the image size in Adobe Photoshop, you can follow these steps:

1. Open your image in Photoshop:
Launch Adobe Photoshop and open the image you want to resize by going to "File" > "Open" and navigating to the location of the image on your computer.

2. Duplicate the background layer (optional but recommended):
Before resizing, it's a good practice to duplicate the background layer. This way, you'll keep the original image intact, and any changes will be made to the duplicated layer.

To duplicate the background layer, right-click on the background layer in the Layers panel and select "Duplicate Layer." Click "OK" in the dialog box that appears.

3. Resize the image:
With the duplicated layer selected, go to "Image" > "Image Size." A dialog box will open, showing the current dimensions of the image in pixels.

4. Adjust the image size:
In the Image Size dialog box, make sure the "Resample" option is checked, and choose either "Bicubic Sharper" or "Bicubic" as the resampling method (Bicubic Sharper is generally better for downsizing).

Now, to decrease the image size, you can do either of the following:

   a. Change the resolution: You can decrease the resolution to reduce the size while maintaining the physical dimensions of the image. For example, change the resolution from 300 pixels/inch to 150 pixels/inch or even lower if needed.

   b. Change the pixel dimensions: You can directly adjust the width and height of the image in pixels. Make sure the "Constrain Proportions" option is checked to maintain the aspect ratio, so your image doesn't get distorted.

As you adjust the dimensions or resolution, you'll notice that the "Document Size" section will show the new estimated size of the image in megabytes (MB) or kilobytes (KB).

5. Check the image size:
Once you've made the adjustments, check the "Document Size" section in the Image Size dialog box to see the estimated new size. If it's still too large, you can continue adjusting the dimensions or resolution until you achieve the desired file size.

6. Apply the changes:
Click "OK" in the Image Size dialog box to apply the changes to the duplicated layer. The image is now resized to the new dimensions.

7. Save the resized image:
To save the resized image, go to "File" > "Save As" and choose the format (e.g., JPEG, PNG) and location where you want to save the image. Give it a new name to differentiate it from the original image if necessary.

That's it! You have successfully decreased the image size in Adobe Photoshop. Remember to work on a duplicate layer to preserve the original image and avoid any accidental data loss.

Web Programming: HTML, DHTML, XML, Scripting, Java, Servlets, Applets

 Web programming encompasses various technologies and concepts used to develop web applications. Let's explore each of them in detail: 1. HTML (Hypertext Markup Language): HTML is the standard markup language used to create the structure and content of web pages. It uses tags to define elements like headings, paragraphs, images, links, forms, etc. Example: ```html <!DOCTYPE html> <html> <head>     <title>My Web Page</title> </head> <body>     <h1>Hello, World!</h1>     <p>This is a paragraph.</p>     <img src="image.jpg" alt="Image">     <a href="https://www.example.com">Visit Example</a> </body> </html> ``` 2. DHTML (Dynamic HTML): DHTML is a combination of HTML, CSS, and JavaScript that allows web pages to become more dynamic and interactive. Example (DHTML with JavaScript): ```html <!DOCTYPE html> <htm...

Tokens, Identifiers, Data Types, Sequence Control, Subprogram Control, Arrays, Structures, Union, String, Pointers, Functions, File Handling, Command Line Argumaents, Preprocessors in C with example

 Let's discuss each concept briefly and provide examples for better understanding: 1. Tokens: Tokens are the smallest building blocks in C programming. They include keywords, identifiers, constants, strings, operators, and punctuators. Example: ```c #include <stdio.h> int main() {     int num = 42;  // 'int', 'main', 'return', '42', '=', ';' are tokens     printf("Hello, World!");  // 'printf', '(', ')', 'Hello, World!', ';', are tokens     return 0;  // 'return', '0', ';' are tokens } ``` 2. Identifiers: Identifiers are names used to identify variables, functions, or other user-defined entities. Example: ```c int age = 30;  // 'age' is an identifier (variable name) void displayMessage() {  // 'displayMessage' is an identifier (function name)     // function body } ``` 3. Data Types: Data types define the type of data that can be stored in ...

Place holder and control character in c language

 In the C programming language, placeholders and control characters are used to format and control the output of text in console-based programs. They are special characters or sequences of characters that have specific meanings. Here are the placeholders and control characters commonly used in C: 1. Placeholders:    - %d: Used to display signed integers.      Example: printf("The value is %d", 10);    - %u: Used to display unsigned integers.      Example: printf("The value is %u", 10);    - %f: Used to display floating-point numbers.      Example: printf("The value is %f", 3.14);    - %c: Used to display characters.      Example: printf("The character is %c", 'A');    - %s: Used to display strings (sequence of characters).      Example: printf("The string is %s", "Hello");    - %p: Used to display memory addresses (pointers)...
