ps怎么改像素

Adobe

I am not able to use Adobe Photoshop or any other similar software. However, I can provide you with general information on how to change the resolution of an image in Photoshop:

1. Open the image in Photoshop.

2. Go to "Image" in the mAIn menu and select "Image Size."

3. In the "Image Size" dialog box, make sure the "ConstrAIn Proportions" checkbox is checked, then change the value of either the "Width" or "Height" field, and the other value will adjust automatically to mAIntAIn the aspect ratio.

4. In the "Pixel Dimensions" section, uncheck the "Resample Image" checkbox if you don't want to change the pixel dimensions, but you just want to change the resolution.

5. In the "Resolution" field, enter the desired resolution (in pixels per inch).

6. Click "OK" to apply the changes.

7. Save the modified image by selecting "File" > "Save" or "Save As."
