I need to convert PVR.CCZ image file to PNG image to edit my image file. m original image got deleted. i used texture packer to create pvr file.
i refer this link:- How can I recover PNG images from a .pvr.ccz file? but not useful.
in Googling u will get. i got this link:- https://gamedev.stackexchange.com/questions/69519/how-can-i-batch-convert-texturepacker-pvr-ccz-files-to-png its worked fine also..
Simple command in terminal will help:-
TexturePacker filename.pvr.ccz --sheet filename.png --data dummy.plist --algorithm Basic --allow-free-size --no-trim

i want to develop a Perl script on centos7 minimal which can easily get data(quadrants) of image from data base and according to those quadrant it can crop that image and save a new file of that cropped image.
I'm currently using opencv C++ to process images that have file type NEF. But imread doesn't seem to work on raw images. Does anyone know how to read and use Bayer filter on a NEF type image? Thanks!

here are some sample pictures.
I am using opencv 3.0 version which has support for creating HDR images and trying to produce an HDR image using three images at different exposure.
And i found this tutorial of opencv.
http://docs.opencv.org/master/d3/db7/tutorial_hdr_imaging.html#gsc.tab=0
Its easy to understand but it takes paramter like exposure times for images.
How do i will get this exposure time ? I have only images. Do any one has tried it already ?
Thanks
Image exposure time is in EXIF data. In the explorer window right click the image, go to properties, you will see some of the EXIF data including exposure time if the image has that data.
or you can write a program to extract metadata to a txt file. I used python exifread() to read exposure time.

I would like to write CPP code that is able to take in a PNG file, scan through its pixels and identify where the transparent pixels are.
I tried doing this with CIMG, but it didn't work out as CIMG only supports the RGB channels. Even after installing image magick, the 4th channel is not giving me the right values.
Anyone can suggest a library I could use?
I'm using this command to ftp upload a png image. But when I upload the image is not visible it looks like currupted even if I download it I can't view the image.
Here is the code
ftp.storlines('STOR ' + 'Simple.png', open('Simple.png', 'rb'))
here is the uploaded file
http://llgrow.co.nf/Simple.png
That's because ftp.storlines() is sending the file in ascii mode, you should use ftp.storbinary() for an image file (binary mode):
F=open("Simple.png","rb")
ftp.storbinary('STOR image.png',F,1024)
Try using storbinary()...
Because it takes the binary values of that image... So that no pixel values are messed up...
Since image files contain pixels... Need to store the exact X,Y positions of the pixels.
So storbinary() does that by default.
