Converting Pixel Array to Image in Java -


i have used this code image array of pixels.

  • convertto2dwithoutusinggetrgb method reading image pixel array
  • writetofile method pixel array image

now convert array of pixels image. when convert it, losing image data.

  1. initial image size: 80kb jpg
  2. duplicate image size: 71kb jpg

i can notice difference between both images, java produced image has sort of white-noise.

i reproduce image without single pixel loss of data, how achieve in java?

the jpg file format uses lossy compression algorithm means files generates have slight differences original. can change quality setting compress more or less can't save original size without modifications.

this why jpg isn't recommended image editing. use lossless format instead, png.

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
