 |
|
Hi all!
Exist a way to load a jpeg Image from Array of Bytes?
I try to save the array to file and after load image from file.
This method is sloooow!
I get this array from wi-fi! The time to get this array from pc is very speedly (1sec.) but the save to file is slow(10-20 sec.)
If is possible load a jpeg image directly from an Array of Byte (the time is speedly (1sec + load from array).
My Code is:
| Code: | myArrayofImage = ""
...
myArrayofImage = myArrayofImage .. socket:recv()
...
file = io.open("img.jpg","wb")
file:write(myArrayofImage)
file:close()
...
myImage = Image.load("img.jpg") |
This method is sloooow!
You know a method for don't save the image to file??
Thanks in advace!!

Yes, see http://forums.ps2dev.org/viewtopic.php?t=5885 . Maybe this will be useful later when integrating physfs, too, which will allow packing all files of a game in one zip file. |

Great work Shine!!
Works perfectly now!
The speed is superrrrrr!!! :D
new function Image.loadFromMemory for loading images from memory:
Code:
| Code: | jpegFile = io.open("test.jpg", "rb")
data = jpegFile:read("*a")
jpegFile:close()
image = Image.loadFromMemory(data) |
PNG and JPEG is supported and autodetected |
