The size of a picture usually refers to the storage space occupied by a picture file, for example, the file size is 100k, which means that the storage space occupied by this picture file is 100KB. Usually, we call this data the file size.
Image size usually refers to the length and width of the image, some pixels, some centimeters.
Second, the difference in meaning.
Size, not in the traditional sense, the bigger the better. But according to the need, it is the most suitable one that can meet the actual output demand. If the size of the picture remains the same, the higher the accuracy of the picture, and of course the higher the quality of the picture.
The size is unchanged, and the parameters of the storage format and related formats are unchanged. Similarly, the larger the size of the picture, the higher the quality of the picture, provided that the parameters of the storage format and related formats remain unchanged and the accuracy of the picture remains unchanged.
In actual printing, if the resolution of the picture is set too high, the phenomenon of "printing paste" will appear. After the big picture is reduced to a certain size, the effect is not as clear as the direct small picture. This is when the computer scales the graph, it will use interpolation.
Extended data:
1, the number of pixels of the same file can be adjusted. For example, if 1600* 1200 is reduced to 800*600, the file size will become smaller.
2. For the same file, the number of pixels remains the same, but when the compression ratio is increased during storage, the file size will also decrease. ?
3, the number of pixels remains unchanged, the resolution increases, and the print size decreases. The number of pixels remains unchanged, the compression ratio decreases and the file size increases. The number of pixels is reduced, the resolution is unchanged, the print size is reduced, and the file size is reduced.
4. The so-called quality and size are not understood in the traditional sense that the bigger the better. But according to the need, it is the most suitable one that can meet the actual output demand.
