layer crop but place uncrop ?

KiboOst · September 4, 2015 at 9:23 AM

Hi,
I have a bitmap with a layout of button.
For each button, I create a new layer with a crop from this bitmap. But as it is cropped, I have to place it (x, y) manually.
Is there a way to crop the bitmap, but place it at same place as if was not cropped ? Si I have not to place each buttons manually, as the layout is correct inside the bitmap ?
Basically, load 20 layer at same scale, x, y but each croped to show only its part.

Thks

Ok, found it ! With parenting each buttons to main bitmap, with align lefttop, then x and y for crop and placement are the same!
Nice!

See this:

Code

<style name="crop_style"  url="images.jpg" />      
<layer name="crop_master" url="images.jpg" onloaded="start();" visible="false" />  


<action name="start" >
set(horizontal_segments,5);
set(vertical_segments,3);


div(layer_x_segment_width,layer[crop_master].imagewidth,horizontal_segments); roundval(layer_x_segment_width);
div(layer_y_segment_height,layer[crop_master].imageheight,vertical_segments); roundval(layer_y_segment_width);
for(set(i,0), i LT horizontal_segments, inc(i), 
  for(set(j,0), j LT vertical_segments, inc(j), 
    mul(element_x,i,layer_x_segment_width);   roundval(element_x);
    mul(element_y,j,layer_y_segment_height);  roundval(element_y);
    txtadd(layer_name,'layer_section_',get(i),'_',get(j));    
    addlayer(get(layer_name));
    layer[get(layer_name)].loadstyle(crop_style);
    copy(layer[get(layer_name)].x,element_x);
    copy(layer[get(layer_name)].y,element_y);    
    txtadd(new_crop,get(element_x),'|',get(element_y),'|',get(layer_x_segment_width),'|',get(layer_y_segment_height));    
    copy(layer[get(layer_name)].crop,new_crop);    
    set(layer[get(layer_name)].onclick,'trace(get(name));');
  );
);


showlog();
</action>

Wow, nice grid system Will try that.
It also show how to dynamically create layers, which was also a question I had.
Thanks !
