I have a website with an upload profile photos for users.
First Try
When I try to upload a small size image, the upload was succeed.
This file property :
Size : 500 KB
Width : 900
Height : 900
Type : jpg
Second Try
When I try to upload a large iamge, I got error message :
The uploaded file exceeds the maximum allowed size in your PHP configuration file.
This file property :
Size : 7,2 MB
Width : 5200
Height : 3500
Type : JPG
This is my config file in my controller :
$config['upload_path'] = "./assets/gambar/pengguna/";
$config['allowed_types'] = 'gif|jpg|jpeg|png';
$config['max_size'] = 25000;
$config['max_width'] = 7000;
$config['max_height'] = 7000;
I tried to change max_size, max_width, and max_height to 0. But I still get bthe same problem.
Refrence to set it 0 to make it no limit from :

If I do:
exiftool -artist=ii realshort.mp4
i can add artist tag with the value ii
But if I do: exiftool -"mime type"=ii realshort.mp4 it won't work
I looked at: https://libre-software.net/edit-metadata-exiftool/
And also here: How do you change the MIME type of a file from the terminal?
But I can't find any answer
How can I make it work?
You can't change the MIME type. It's not embedded data. It's a tag derived from what the type of file is.
You could edit try editing the .Exiftool_Config file if you have one (see the example config) to override the base definition, but that will only change what exiftool displays. Another program or another computer will output MP4 as the MIME type.
i'm using the Google-api-python-client to upload some emails to a google groups.
the upload works fine until i got this error while uploading... .
File "/Users/xxxxx/Downloads/pythonClientLibrary/google-api-python-client-1.8.3/googleapiclient/discovery.py", line 861, in method
raise MediaUploadSizeError("Media larger than: %s" % maxSize) googleapiclient.errors.MediaUploadSizeError: Media larger than: 26214400
is there any way to change/increase the value of the 'maxSize' variable to be able to upload mails with size larger than 26mb ?
apparently 25MB is the max size of a message, that is allowed to be transferred using the Groups Migration API
so in my code, i checked if the msg size is > 25mb then ignore this msg.
message_size = msg.as_string().__sizeof__()
if message_size >= 26214400:
print('Message {} - Size {} - subject : {} - from: {} - to: {}'.format(i, message_size, msg['subject'], msg['from'], msg['to']))
continue
I want to preserve image metadata but my code strips all metadata. How do I stop this? I run this script from the MATLAB SDE command prompt. Code is below:
p = which('G0011363.JPG');
filelist = dir([fileparts(p) filesep '*.JPG']);
fileNames = {filelist.name};
fileNames_size = size(fileNames,2);
number_of_colums = fileNames_size;
for k = 1:number_of_colums
imwrite(undistortImage(imread(fileNames{k}), cameraParams2cof, 'OutputView', 'valid'), (strcat(int2str(k), 'R2_3COF_ONRcorrected.jpg')));
end
You can read in metadata using imfinfo, and you can write specific metadata to your image file with imwrite (as long as the particular tag is supported) as key/value pairs. Look at help imwrite for more info.
Example:
>> I = imread('NeverGonnaGiveYouUp.png');
>> imwrite(I, 'output.png', 'png','Author','Rick Astley');
>> Iinfo = imfinfo('output.png');
>> Iinfo.Author
ans =
Rick Astley
I found a solution, but it isn't perfect...
Note: The posted solution applies Windows OS.
Where referring to image metadata, I assume you mean Exif data.
According to https://www.mathworks.com/matlabcentral/answers/152559-writing-exif-data-to-jpg
Unfortunately, there is currently no off-the-shelf functionality to write EXIF data to an image file in MATLAB. You can only read EXIF data from an image file ( exifread and imfinfo ).
You can use run_exiftool do copy Exif data from one image to another:
Download and extract exiftool-10.25.zip
Copy file exiftool(-k).exe to your working folder, and rename file to exiftool.exe
Download run_exiftool from https://www.mathworks.com/matlabcentral/fileexchange/42000-run-exiftool, Copy getexif.m and putexif.m to your working folder.
Try the following code sample:
%Copy the file from c:\Program Files\MATLAB\R2014b\mcr\toolbox\matlab\demos\ to local folder.
%Note: ngc6543a.jpg is part of Matlab installation.
copyfile([matlabroot, '/mcr/toolbox/matlab/demos/ngc6543a.jpg'], cd);
%Read image
I = imread('ngc6543a.jpg');
%Save I to myfile.jpg and add Exif data of ngc6543a.jpg to myfile.jpg
status = putexif(I, 'myfile.jpg', 'ngc6543a.jpg');
%Read Exif data from ngc6543a.jpg
[ngc6543a_exifdata, ngc6543a_nf] = getexif('ngc6543a.jpg');
%Read Exif data from myfile.jpg
[myfile_exifdata, myfilenf] = getexif('myfile.jpg');
I am getting a warning message: Warning: Exif tags may not have been copied, but it seems to work.

How to edit or add exif metadata by graphicsmagick command? I've tried the following:
gm convert -set EXIF:XPKeywords "bird, sleep, moon" bird.jpg bird2.jpg
My command is executing successfully and the image is creating but the exif metadata is not updating.
I don't believe you can do that with GraphicsMagick, and I would suggest exiv2 like this:
exiv2 -M"add Exif.Image.XPKeywords Ascii 'bird,sleep,moon'" image.jpg
Then you can view them with jhead too:
jhead -v image.jpg

I know that some of this data is viewable in iPhoto, such as latitude, longitude, and altitude, but is there more than this available? More specifically I am wanting to get the direction of the image as well, which is part of the EXIF format. Or does something other than geotagging need to be enabled (something to do with the compass)?
I suggest installing the command line tool exif. You can get it through Mac Ports by executing port install exif as root.
Here's an example of the exif info stored in a photo I took on an iPod Touch:

EXIF data contains a thumbnail (10215 bytes).
I don't think the iPod Touch has the same capabilities as an iPhone regarding GPS.
It looks like an iPhone will have the data 'GPSImg Direction' as well, which sounds like what you want. I don't think you have to do anything special to enable it, as I haven't found much info on this through searching.
Okay, good news :). The direction is stored in GPS Img Direction. Here's what I was able to get from a photo taken from an iphone (with location services and compass turned on) using the ExifTool mentioned by #rwong.

you don't need an 'external' tool to view all the EXIF-infos, with the iPhone-app iMetaPhoto you can show all metainfos (EXIF, TIFF, IPTC, GPS, AUXiliary EXIF,...) and (the best of all) you can modify the most of them, esp. you can modify GPS ImgDirection.
