Opening image with PIL with tf.data

By : Goecol Johnbosco

To fix this issue As suggested by @GPhilo, using the tf.py_func would solve this problem. Here's my solution code
code :
def read_labels(lbl_filename):
    train_lbl = Image.open(lbl_path + lbl_filename.decode("utf-8"))
    train_lbl = np.asarray(train_lbl)
    return train_lbl

def preprocessing(img_filename, lbl_filename):
    train_lbl = tf.py_func(read_labels, [lbl_filename], tf.uint8)

Wx Python image viewer - atfer opening an image file menu is too tight

this one helps. You can call self.Frame.SetMinSize(w, h) to force the window to have a reasonable minimum height and width, but you will want to add scrollbars so that you can see all of the image... I tried to do that but I am a beginner as well and don't have the time at the moment, sorry. Good Luck!

This might help you To start with, there is no standard C++ library to process images. Secondly, jpeg and png image formats are compressed image formats that need some complex sort of decompressing algorithm. So to start work with images you have two ways:

this one helps. I think I got right also the lightbox show only after img is fully loaded:
code :
<div id="hiddenDiv"><img src="" id="hiddenImg"/></div><a href="#" id="testa">Click Here</a>
#hiddenDiv {     display: none; }
 $("#testa").bind('click', function(e){

type: "POST",
data       : {
username:   username,
password:   password,
img:        img
url: php_url, 
success: function(data){ //read the value and save in settings
if (data.length>0) {
        $('#hiddenImage').html('<img src="data:image/jpeg;base64,' + data + '" />'); 
        $("#hiddenImage").load(function() {
             $.colorbox({inline:true, href:"#hiddenImage"});

Uploading image to WCF service gets image size reduced and image is not opening

By : David Beitl

This might help you I am trying to upload images and other files using WCF service and images and other types of files are getting uploaded successfully. But what issue I am facing is that when I upload image of few KB's it gets uploaded and I am able to open it up nicely. But when the image size is big like I tried to upload image of 800 KB only 10KB gets uploaded and also it does not open up or it is corrupt. , You service code contains these lines:
code :
    byte[] buffer = new byte[10000];
    stream.Read(buffer, 0, 10000);
    FileStream f = new FileStream(Path+fileName   , FileMode.OpenOrCreate);
