This function gets the dimensions of pixels contained in a string. It works with all pixel formats.
Syntax
int, int dxGetPixelsSize ( string pixels )
Required Arguments
- pixels: The pixels to get the dimensions of
Returns
Returns width and height of the pixels if successful, false if invalid arguments were passed to the function.
Example
The example loads an image, gets its pixels, and outputs the pixels size. (You can use this image to test.)
addEventHandler('onClientResourceStart', resourceRoot, function()
local img = fileOpen('img.jpg')
local pixels = fileRead(img, fileGetSize(img))
local size = dxGetPixelsSize(pixels)
outputChatBox('Pixels size is: ' .. size)
fileClose(img)
end)
