Before the image format conversion, the output phpinfo () to view the PHP library information, to see if the GD extension Library is open, if not opened, opened the php.ini file, Use the Find tool to find Extension=php_gd2.dll, Extension=php_ Gd2.dll the ";" in front of you.Here the conversion to JPG format is required for JPEG support, PNG supports PNG support, corresponding to check the format of the firs

PHP Tutorial convert BMP format picture to JPG format program function Imagebmp ($img, $file = "", $rle =0){ $colorcount =imagecolorstotal ($IMG); $transparent =imagecolortransparent ($IMG);$istransparent = $transparent!=-1; if ($istransparent) $colorcount-; if ($colorcount ==0) {$colorcount =0; $bitcount = 24;}

. Save ("New jpg file path", imageformat.jpg);Note: Don't forget to introduce namespaces.In addition, the compression rate of JPG relative to the same size of the content of BMP is also different, in short, very large. In particular, simple graphics compression rate is very good.----------------------------------------

Or something about the image format. The libjpeg library is used to convert JPEG images to the BMP format. The decompression principle is still relatively complex and may be detailed in the future. This is just the use of the library. First download libjpeg library, URL here: http://www.ijg.org/ Then you need to configure the environment. I used vs2010 in windows. For the compilation library, refer to this

We know that the Windows system contains a variety of file formats, take us more familiar with some of the file format for example! text files, we have Word and txt, picture files have bmp, JPG, of course, we can not fully introduce here, but on the other hand, Although the format of each
