and then divided by 0xff. Remarks When the alphaformat parameter isAc_src_alphaThe source bitmap must be 32 colors. If not, the alphablend function fails. When the blendop parameter isAc_src_overThe source bitmap is placed on the target map based on the Alpha value of the source pixel. If ac_src_alpha is not set for the source bitmap, both the source and target bitmaps are determined by the sourceconstantalpha value, as shown in the following table. Note that the value of sourceconstantalpha

Step 1: manual Introduction Shutil -- high-level file operations is a high-level file operation tool. Similar to the advanced API, and its major strength lies in its support for file copying and deletion operations. Related API Introduction Copyfile (SRC, DST) Copy the source SRC to DST. Of course, the premise is that the target address has the write permission. The thrown exception information

One, copy files1. Shutil.copyfile (SRC, DST): Copies the contents of the file (not including metadata) from SRC to DST. DST must be the full target file name; copy directory see Shutil.copy (). If SRC and DST are the same file, an error shutil will be thrown. Error. DST must

between Memcopy and Memmove (written, interview)The memcopy and Memmove functions read the source code for two functions under Linux.The two functions are defined in the header file string.h, and the function prototypes are:void * __cdecl memcpy (void * dst,const void * src,size_t count);void * __cdecl memmove (void * dst,const void * src,size_t count);The implementation code is as follows:void * __cdecl m

second is a keyword that determines the direction of transmission, mainly including src,dst,dst or SRC,DST and SRC, which indicate the direction of the transmission. For example, SRC 210.27.48.2, which indicates that the source address in the IP packet is 210.27.48.2, DST net 202.0.0.0 indicates that the destination n

) The height of the copyThe PCT image merge degree, value 0-100, when pct=0, actually did nothing, reverse completely merges. This function is exactly the same as imagecopy () for the palette image when pct = 100 Know the usage, to achieve our function is simple, with the following code can be easily implemented The code is as follows Copy Code Header ("Content-type:image/jpeg");Original image$DST = "Images/flower_1.j
