I'm use galleria with StreamedContent to show images from c://. The galleria show the images correctly, but when I use the buttons to scale the image with pe:imageRotateAndResize, it only affects the first image, and when I change the image and use the buttons, it still affects only the first image in the gallery. What do I need or what do I have to correct so that pe:imageRotateAndResize affects the current image of galleria and not just the first one? Primefaces and PrimefacesExtensions version 6.0-6.0.0
Code of xhtml:
<p:galleria id="galleriaC" var="galle" value="#{controller.imagenes}" autoPlay="false" showCaption="false"
style="width: 100%; max-width: 100px; min-width: 100%; min-height: 10px; height: auto; overflow:scroll; ">
<p:graphicImage id="myImage" value="#{controller.imageItem}" style="width: auto; height: 100%;">
<f:param name="gh" value="#{galle}"/>
</p:graphicImage>
</p:galleria>
<pe:imageAreaSelect id="areaSelect"
for="myImage"
widgetVar="areaSelectWidget"
autoHide="true"
handles="false"
movable="false"
persistent="false"
resizable="false"
>
<p:ajax event="selectEnd" listener="#{controller.selectEndListener}" update="msg"/>
</pe:imageAreaSelect>
<pe:imageRotateAndResize id="rotateAndResize" for="myImage" widgetVar="rotateAndResizeWidget" >
<p:ajax event="rotate" listener="#{controller.rotateListener}"
update="msg" oncomplete="PF('areaSelectWidget').reload();"/>
<p:ajax event="resize" oncomplete="PF('areaSelectWidget').reload();" />
</pe:imageRotateAndResize>
<p:commandButton value="Regresar" actionListener="#{controller.regresar()}" update=":form"/>
<p:commandButton icon="ui-icon-zoomin" value="Scale +"
onclick="PF('rotateAndResizeWidget').scale(1.05);return false;"/>
<p:commandButton icon="ui-icon-zoomout" value="Scale -"
onclick="PF('rotateAndResizeWidget').scale(0.95);return false;"/>
Code Java:
public List<String> getImagenes() {
return imagenes;
}
public StreamedContent getImageItem(){
FacesContext context = FacesContext.getCurrentInstance();
try{
if(context.getRenderResponse()){
return new DefaultStreamedContent();
}else{
//String name = context.getExternalContext().getRequestParameterMap().get("gh");
Map<String,String> params = context.getExternalContext().getRequestParameterMap();
String nmFile = params.get("gh");
File imgFile = new File(nmFile);
System.out.println("File a stremear: "+nmFile);
StreamedContent ds = new DefaultStreamedContent(new FileInputStream(imgFile),context.getExternalContext().getMimeType(imgFile.getName()));
return ds;
}
}catch(Exception e){
e.printStackTrace();
}
return null;
}
public void selectEndListener(final ImageAreaSelectEvent e) {
final FacesMessage msg = new FacesMessage(FacesMessage.SEVERITY_INFO, "Area selected",
"X1: " + e.getX1() + ", X2: " + e.getX2() + ", Y1: " + e.getY1() + ", Y2: " + e.getY2()
+ ", Image width: " + e.getImgWidth() + ", Image height: " + e.getImgHeight());
FacesContext.getCurrentInstance().addMessage(null, msg);
}
public void rotateListener(final RotateEvent e) {
final FacesMessage msg = new FacesMessage(FacesMessage.SEVERITY_INFO, "Image rotated",
"Degree:" + e.getAngle());
FacesContext.getCurrentInstance().addMessage(null, msg);
}
