----------------------------------
Summary: Camera.getPicture(); aspect ratio resize. Camera.cs
Key: CB-2737
URL: https://issues.apache.org/jira/browse/CB-2737
Project: Apache Cordova
Issue Type: Improvement
Components: CordovaJS
Affects Versions: 2.5.0
Environment: Windows8. Camera.cs
Reporter: Dimitri Adamou
Assignee: Filip Maj
Hey there, noticed windows8 phone proj. was missing aspect ratio resize so
added it in (Essentially copied iOS code)
---
private struct ResizeDimension
{
public int width;
public int height;
}
private ResizeDimension ResizeAspectRatio(int oWidth, int oHeight, int
tWidth, int tHeight)
{
ResizeDimension tgt;
float widthFactor = (float)tWidth / (float)oWidth;
float heightFactor = (float)tHeight / (float)oHeight;
float scaleFactor;
if (widthFactor > heightFactor)
scaleFactor = heightFactor;
else
scaleFactor = widthFactor;
tgt.width = (int)Math.Min((float)oWidth * scaleFactor, tWidth);
tgt.height= (int)Math.Min((float)oHeight * scaleFactor, tHeight);
return tgt;
}
---
and works via
ResizeDimension rd = ResizeAspectRatio(image.PixelWidth, image.PixelHeight,
cameraOptions.TargetWidth, cameraOptions.TargetHeight);
image.SaveJpeg(stream, rd.width, rd.height, 0, cameraOptions.Quality);
Cheers,
Dim
