Re: Is there any GWT library to be used in client side that does the same thing as Scalr (scale and reduze image file sizes)?

Hi Claudio,

thank you for your post. You method could only be used if implemented on the server side.

GWT does not support the awt API.

Regards!

How do you use AWT code in client GWT code ?

Hi julio

i use this routine to redimensione my images

public static BufferedImage redimensionarImagem(BufferedImage img, int maltura, int mlargura) throws Exception {

java.awt.Image imagem = (java.awt.Image) img;

java.awt.Image thumbs = ((java.awt.Image) imagem)

.getScaledInstance(mlargura, maltura, BufferedImage.SCALE_SMOOTH);

BufferedImage buffer = new BufferedImage(mlargura, maltura, BufferedImage.TYPE_INT_RGB);

buffer.createGraphics().drawImage(thumbs, 0, 0, null);

return buffer;

}

pass the width and height in pixels (maltura e mlargura)

After thar you can upload the image.

cheers

Claudio

Hi guys,

i am trying to upload images with 2mb size but i don't want to send the whole original image to the server.

What i would like to do is reduce the image dimensions from, for example, 1000x1000 to 50x50 and reduce the file size
from 2mb to ~25kb as well and at the end send the ~25kb image to the server.

I know there is the Scalr framework that does that in java, but its no compatible with GWT clients.

Is there any client side GWT library that does the same thing as Scalr?

Best Regards!
