Is it possible to resize images taken from media.show(media.Camera) in an app itself?

Solar2D General Questions/Discussion
#1

I could do with being able to resize images before they are uploaded to a server, so that people with a hi-res camera don’t have their data allowances eaten away by a few uploads.

Is there a way to save the image as a fixed size? [import]uid: 84115 topic_id: 31173 reply_id: 331173[/import]

I also need a lot to resize images but there is no such a feature in Corona.
If there will be a lot of people to request image resizing I think they will add it.
Feel free to send suggestions (or propositions) by contacting Corona via the below link.

One technique is to resize the image using the display… This limits your overall image size to the maximum display size though – but it does work.

This is a code excerpt, so you’ll have to work with the idea:

local function cameraDone(event)  
  
 print(" -- cameraDone(event) entered.")  
  
 if( event.target ~= nil ) then -- User took a photo...  
 t = event.target  
  
 local photot = display.newGroup()   
  
 print(" -- saving portarait mode")  
 t.width = mojoData.\_DeviceScreenCapWidth / 2 -- Adjust size  
 t.height = mojoData.\_DeviceScreenCapHeight / 2   
  
 photot:insert(t)  
 photot.x = 320   
 photot.y = 480  
 local baseDir = system.TemporaryDirectory  
  
 imageFilename = utils.getUniqueFilename()  
 imageFilename = imageFilename .. ".jpg"   
  
 display.save(photot, imageFilename, baseDir)   
  
 photot:removeSelf() -- Now get rid of it... (system puts it onscreen when group is created)  
 end  
end

Good Luck! [import]uid: 79933 topic_id: 31173 reply_id: 124692[/import]
