"Pixel" is a unit used to calculate digital images, just like photographic photographs, digital images also have continuous shades, if we magnify the image several times, we will find that these continuous tones are actually composed of many small square dots of similar colors, these small square dots are the smallest units that make up the image.
pixel.
DPI is an abbreviation for "dot per inch". Refers to the print resolution, which represents the pixels per inch in length. Usually, we all use DPI as the resolution of scanners and printers.
Units, higher the value indicates higher resolution.

Anonymous users2024-02-14"Pixel" is a unit used to calculate digital images, just like photographic photographs, digital images also have continuous shades, if we magnify the image several times, we will find that these continuous tones are actually composed of many small square dots with similar colors, these small square dots are the smallest unit of the image "pixel". This smallest graphic unit can display what is usually a single dot of color on the screen. The higher the pixel, the richer the color palette and the more realistic the color is.
A pixel is often considered the smallest complete sample of an image.
Pixels are generally used to represent size: such as 1024x768, it means that it has 1024 pixels horizontally and 480 pixels vertically, and the total number of pixels is 1024x768 = 786432 pixels (that is, more than 780,000 pixels).
If you want 150 pixels, then the length and width of the image are multiplied by about 1.5 million.
DPI is an abbreviation for "dot per inch". Refers to the print resolution, which represents the pixels per inch in length. Typically, we use DPI as the unit of resolution for scanners and printers, with higher values indicating higher resolution.
150dpi means that there are (printed) 150 pixels in one inch.
DPI is used in the field of printing.
Pixels are used in the field of image display.
There is no question of conversion.
Example: The same size of 1900x1200 is printed at 150dpi and 300dpi respectively The print size of 300dpi is smaller than the print size of 150.
However, at 300 resolution, the printed image is tighter and clearer.

Anonymous users2024-02-13DPI refers to the number of pixels per unit area, that is, the scanning accuracy, and the number of pixels in an inch area is currently calculated internationally. The smaller the dpi, the lower the definition of the scan, due to the influence of the network transmission speed, the ** used on the web is 72dpi, but the flushing ** can not use this parameter, it must be 300dpi or higher 350dpi. For example, if you want to develop a 4*6-inch **, the scanning accuracy must be 300, then the file size should be (4*300)*(6*300)=1200 pixels*1800 pixels.

Anonymous users2024-02-12Hello and glad to answer your question, 300dpi is 300 pixels, and 300dpi means 300 pixel units in an inch of area. DPI refers to the number of pixels per unit area, that is, the scanning accuracy, the unit of pixels in an inch area is calculated by default, the smaller the DPI, the lower the definition of the scan.

Anonymous users2024-02-11Summary. Hello, 300dpi means 300 dots (dot or pixel) on every inch (inch). Therefore, the number of pixels at 300dpi can be calculated by multiplying the number of pixels per inch of length and width by 300.
For example, if an image is 4 inches and 6 inches long and 6 inches wide, and you want to output it as 300 dpi, the image has a resolution of 1200x1800 pixels (300dpi for 4 inches and 300dpi for 6 inches). So, the number of pixels at 300dpi depends on the physical size and resolution of the image. If the resolution is higher, there will be more dots per inch and therefore a higher number of pixels.
What are the 300dpi pixels.
Hello, 300dpi means that there are 300 dots (dot or pixel) per inch of inch. So, a pixel count stupid row of 300dpi can be calculated by multiplying the number of pixels per inch of length and width by 300. For example, if an image is 4 inches and 6 inches long and 6 inches wide, and you want to output it as 300 dpi, the image has a resolution of 1200x1800 pixels (300dpi for 4 inches and 300 dpi for 6 inches).
300dpi does not represent a specific number of pixels, but the number of dots per inch. Therefore, to calculate the exact number of pixels, more information is needed, such as the size of the socks printed in the trembling file. For example, if you want to print a 10" x 8" ** with a resolution of 300 dpi to print, the number of pixels in this ** is:
10" x 300dpi = 3000 pixels (width) 8" x 300dpi = 2400 pixels (height) Therefore, this ** has 3000 x 2400 pixels.

Anonymous users2024-02-10300dpi means that there are 300 dots in 1 square inch, and the resolution of digital laser printing is generally 300dpi.
For example, if the photo taken is 1.5 million pixels (1024x1536), divide 1024 and 1536 by 300 to get an inch x 5 inch (i.e. 3r size). In other words, the maximum limit for 1.5 million pixel digital photo printing is 3R, the maximum limit for 2 million pixel digital photo printing is 4R, and so on.

Anonymous users2024-02-09dpi means the number of pixels contained in each inch, if the resolution is 300dpi, then it means that there are 300 pixels in an inch, so you can calculate it in this unit, which is the screen size of the device.
Convert it in inches and multiply it by this resolution to calculate the total number of pixels on the device's screen.

Anonymous users2024-02-07300dpi is 300 pixels in an area of one square inch.
Because 300dpi has 300*300 dots per square inch. Moreover, pixels are made up of small squares of an image, and these small squares have a clear position and assigned color value, and the color and position of the small squares determine the appearance of the image.
So. 300dpi is 300 pixels in an area of one square inch.

300dpi 1 cm = pixels. dpi is pixels per inch, which is the scanning accuracy. The lower the dpi, the lower the clarity of the scan.
Due to the influence of network transmission speed, the ** used on the web is 72dpi, but the flush** cannot use this parameter, it must be 300dpi or higher 350dpi.
It's about the same as pixels.

Anonymous users2024-02-05What are the 300dpi pixels.
Hello! According to the description of your question, 300dpi refers to the density of 300 pixels per messy inch, so the exact number of pixels will vary depending on the size of the output.
If we take A4 paper (210mm 297mm) as an example, then in the case of 300dpi, the number of pixels required is:- Width: 210mm 300dpi 2480 pixels- Height:
297mm 300dpi 3508 pixelsTherefore, when outputting an A4 size image with a resolution of 300 DPI, the number of pixels required is 2480 3508 pixels. It should be noted that the output size and resolution of different types of pixels will have different effects, and the specific calculation method can be estimated according to the above formula.

Anonymous users2024-02-041. It is the number of pixels in the length of each inch of the image, which is a unit and represents the printing accuracy.
2. It's pixel inches.
dpi means the number of ink drops per inch, for example, 600dpi means that the number of ink droplets per inch is 600.
The relationship between the print size, the number of pixels of the image, and the print resolution can be expressed using the following formula:
Number of horizontal (vertical) pixels of the image = Horizontal (vertical) resolution of the print Horizontal (vertical) dimensions of the print;
Number of horizontal (vertical) pixels of the image = Horizontal (vertical) resolution of the print Horizontal (vertical) dimensions of the print;
