account. Multiply the size values by the value in the scale property to get the pixel dimensions of the image.
That is to say, the size of the image is multiplied by the size of the image and the scale to obtain the size of the physical pixel.Problem

Screen SizeIt refers to the length of the diagonal line of the screen, generally in inches, 1 inch (inch) = 2.54 cm (cm ). In the traditional sense, the photo size is also the conc

The iphone 4 and iphone 3GS screen sizes are actually the same, all 3.5 inches. The same point, in fact, looks the same, except that the IPhone 4 has more pixels in the unit inch and looks more delicate. 2. What is the difference between PT and PX.
PT (point) represents the pixel, px (PIEXL) represents pixels, this is two looks like, but
can meet the requirements. It should be noted that the image resolution is at least as large as the display resolution, or higher. If the image you are shooting will be placed on a projector for playback in the future, then the resolution of the selection should not be lower than the projector resolution.
Third, the
InstanceRecently made a visual inspection of the app project, which used to convert the pixel to the actual size, after the research learned some knowledge, here and you share.The implementation steps are: First get the physical parameters:1. Cell phone pixel density (1 inches =x pixels) Dpix/dpiy2. Ratio of actual pixel to logical
pixels, and the higher the DPI value, the finer the image, the smaller the pixel to the point that the human eye cannot tell, and the image looks different from the actual one.
This is the concept of "how many thousands of pixels" for a digital camera. For example, a camera can take up to 1600 pixels * 1200 pixels of photos, the pixel value is 1600*1200 = 1.92 million, which is about
