Yesterday afternoon, I mentioned that "there must be a relationship between pixel resolution and pixel size. The smaller the pixel size, the higher the resolution." My colleagues and I argued that my concept is problematic, the two are two different concepts. Today, I calmed down and carefully analyzed whether there was any connection between them. Finally, I fo

You can use some methods of the tbitmaputil class to process bitmaps in pixels. Including: Void begin (const tpoint aposition): Set the current pixel location to be processed and lock the heap. Void end (): Unlock the heap. Void setpos (const tpoint aposition): Change the current pixel position to aposition. Void incxpos (): Auto-increment the current X coordinate by 1. Void decxpos (): Subtract the

1. pixel focal length and millimeter focal length conversionFu = Ku * DPX;FV = Kv * dpy;1) ku and KV are pixel focal lengths in the X (U) and Y (v) Directions of the internal camera matrix;2) Fu and FV are the millimeter focal lengths in the X (U) and Y (v) Directions of the camera respectively;3) DPX and dpy are measured in mm/pixel;4) DPX and dpy indicate valid

Next, let's talk about some simple algorithms in the previous article. In this article, let's talk about the fragment algorithm. Let's talk about it first: This is a destructive filter. For beauty, it is because 90% of the people who engage in images are men and half of the men. The principles of the fragment filter can be found on the network to create four copies of the image at the same offset to produce a similar effect. With the above sentence, we can start it. Analysis: Through the compar
