Checking Image size using jQuery validation not working

|▌冷眼眸甩不掉的悲伤 提交于 2021-01-29 08:42:25
问题 I am uploading an image to the folder but before uploading, I am checking the image extension and size. I am using jQuery validation. I checked on SO before uploading the question and I found the code. But the issue is when I am uploading an image which is less than 100kb(actual image size is 98kb) then I am getting the error "File size must be less than 5" . I tried another image which is 3.8MB but still getting the same error. Would you help me out what size of the image I have to use here?

问题 I want to know width and height of an image file before opening that file. So, how to do that? EDIT: This refers to jpg, bmp, png and gif types of image files. 回答1: If by 'image file' you mean those raster image files recognised by the VCL's graphics system, and by 'before opening' you mean 'before the user is likely to notice that the file is opened', then you can do this very easily: var pict: TPicture; begin with TOpenDialog.Create(nil) do try if Execute then begin pict := TPicture.Create;

Reducing the size (as in area) of the graph generated by graphviz

依然范特西╮ 提交于 2019-12-29 02:33:23
问题 Does anyone have any general tips for reducing the size of a graph generated by graphviz (size as in area, not as in file size). I have a fairly large graph (700 nodes). I set a smaller font size for each node, but it seems to only reduce the font size and not the actual node size. Are there any attributes to reduce the overall amount of blank space in the graph also? Thanks! 回答1: In my experience using graphviz to render graphs of that size (~ 700 nodes), minimal trial-and-error adjustment
