How to Convert Compressed Image File Formats to Uncompressed Image File Formats in PHP -


i have question image compression. know how uncompress images such jpg, png , such file formats such tiff or bmp , vice versa via php or other scripting language? there library this?

thanks in advance help! :)

sincerely, piotr.

there library called gd this. there other libraries imagemagick , graphicsmagick (gmagick) can well.

the principle of these libraries is:

  1. open picture
  2. save picture in format of wish (tiff, bmp, ...)

i not recommend gd library not support file-types you're asking (tiff, bmp).

next using libraries, can invoke command-line tool convert image files imagemagick or graphicsmagick.
