For example, if the resolution is 300dpi, if the document size is 1 inch, the pixels are 300. If it is 150DPI, then the pixel is 150.
So it's also A4, any pixel can do it, just change the resolution.
Because A4 has different lengths on both sides, generally only one side is required to be 2048 pixels, and the other side is scaled proportionally.
Specific practices:
1 brand new 2 10mm×297mm canvas with 300 pixels/inch resolution. (or crop the picture to 2 10mm×297mm)
Open the Image Size command and make sure that Redefine Image Pixels and Constrain Scale are selected.
3 directly change the pixel on the side with larger top pixel size to 2048, and Photoshop will automatically calculate other options. At this time, the pixel size should become 2048 x1448 = 2.96 million pixels, ok.
4 Open the image size command, cancel the option of "redefine image pixels", and then change the document size to: 2 10 mm× 297 mm, and the resolution will directly become 175.438+049 dpi.
In this way, an image with 2.96 million pixels and A4 format is established. In fact, after knowing this conclusion, you can directly crop the image with the resolution of 210mm× 297mm175.149, and then the pixels naturally become 2048X 1448.
