The formula to calculate the new dimensions of an image when resizing is:
\[ ND = OD \cdot R \]
Where:
Let's say the original width (OW) is 1920 pixels, the original height (OH) is 1080 pixels, and the resize ratio (R) is 0.5. The new dimensions would be calculated as follows:
\[ NW = 1920 \cdot 0.5 = 960 \text{ pixels} \]
\[ NH = 1080 \cdot 0.5 = 540 \text{ pixels} \]
So, the new dimensions are 960 pixels by 540 pixels.
Pixel Resize refers to the process of changing the size of a digital image by adjusting the number of pixels. This can be done by either increasing (upsampling) or decreasing (downsampling) the pixel count. The quality of the resized image can vary depending on the resizing algorithm used. It’s important to note that upsampling can often lead to a loss in image quality as the software has to ‘guess’ the color values for the new pixels created.
