问题 Trying to download the postview image in original size I'm getting an error on setting "Postview image size" parameter to "Original". Downloading (and setting) the postview image with "2M" size is working well. Are there any undocumented limitations on downloading original sized postview images? My camera model is ILCE 5100 with latest firmware installed. Edit: json request: {'method': 'setPostviewImageSize', 'params': ["Original"], 'id': 1, 'version': '1.0'} response: {'id': 1, 'error': [1,

问题 I did a quick google search, but I couldn't find the max image/texture resolution for android. I currently have an image that is crashing , but when I lower the resolution it works. I dont want to just trial and error the resolutions to see if it works, some solid numbers showing limitations would be ideal. A link to the android documentation would be fine as well. I personally don't find it intuitive. 回答1: If it fails at a high resolution but works with a lower resolution, it sounds to me

问题 I am using a template that I bought offline that uses JavaScript. I am not that great with JavaScript and I would like to make it so that the logo goes from being small to larger as soon as the user clicks on one of the links above example: Before: After: As I said before I am not good at JavaScript, I am fairly good at HTML and CSS, but stil a little grey on advanced CSS. Is there a way I can do this on page change. The code for this is all one single page and does not reload from server so

问题 Let's say I have an image called hello.png with dimensions 200x100 . I create a button using that hello.png like this: var button = Titanium.UI.createButton({ bottom : 50, backgroundImage : "images/hello.png", width:100, height:"auto"; }); window.add(button); What would be the appearance of the height of the button on the device? Would it be 200 pixels or would it be much less than 200 (maybe say 50)? Based on what I've found on google, the button should be 200 pixels. But when I compile the

问题 I will train my dataset with faster-rcnn for one class. All my images are 1920x1080 sizes. Should I resize or crop the images or I can train with this size? Also my objects are really small (around 60x60). In the config file there are dimensions written as min_dimension: 600 and max_dimension: 1024 for this reason I am confused to train the model with 1920x1080 size images. 回答1: If your objects are small, resizing the images to a smaller size is not a good idea. You can change the max

问题 There is this new thumbnail view on Facebook (see image beneath this text). But every command or property I tried, I never get this when posting with the api... This is how my post event looks like right now: $status = $facebook->api('/me/feed', 'POST', array('access_token' => $page_access_token, 'fields' => 'picture.height(960).width(1833)', 'message' => $text, 'icon' => 'http://www.renoi.de/images/lg.jpg', 'link' => $link, 'name' => $title, 'user_generated' => 'true', 'images[0]' => $pic2,

问题 Following is the code snippet - list($campaign_image_width, $campaign_image_height, $campaign_image_type, $campaign_image_attr)=getimagesize($campaign_image); Wherein $campaign_image contains the url of third party images. Problem $campaign_image_width comes out empty for this url - https://lh3.googleusercontent.com/VRY0O_3L8VH2wxJSTiKPr72PeM5uhPPFEsHzzYdxenddpTI150M0TYpljnZisQaROR0=h256-rw I am not sure if it is the limitation of getimagesize(), because of unsupported format, which is

问题 I want to that when a user clicks a button, he can choose gallery or camera, and that the program can retrieve the captured/picked photo. I tried a couple of things, but nothing seems to work completely. This is how I start the gallery so the user can pick a photo: Intent i = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI); startActivityForResult(i,3); And this is how I try to retrieve the by the user picked photo: Uri selectedImage = data.getData

问题 I intend to use pre-trained model like faster_rcnn_resnet101_pets for Object Detection in Tensorflow environment as described here I have collected several images for training and testing set. All these images are of varying size. Do I have to resize them to a common size ? faster_rcnn_resnet101_pets uses resnet with input size 224x224x3. Does this mean I have to resize all my images before sending for training ? Or It is taken care automatically by TF. python train.py --logtostderr --train
