How to resize original image that received from server

Question

Hi Helper's,
I'm getting error on time of resizing image such as "Error #2030: End of file was encountered". I want to resize as per specified size. Code is written in Flash builder 4.5. Please find my code below and help me to correct.

If anyone faced similar kind of problem?

Is there a specific reason why using a BitmapImage would not work for your use case? If you are worried about the overhead, I would take a look at the source and copy out the bits you need. One thing I noticed after looking at the source is that they do not use any kind of encoder to perform that functionality. Is there a specific reason you need this?
Thanks for your reply and happy to see you.
No reason, I got above code When I google it and changed accordinaly to meet req. My requirement is, server will be giving 400*350 (Byte array) size image. That one what to resize into 75*100 and apply it to image component. I'm fine with any approarch, however if the image size is less than 75*100, then should not stretch the image. I have tried with fillMode (BitmapFillMode.CLIP), scaleMode(BitmapScaleMode.LETTERBOX). Please update your concern on same.
Note: Plz ignore this maxWidth="59" property in BorderContainer property.
