The release notes of daily build CoronaSDK 2012.771 says

Sprite: add trimming support to new Sprite API

How do i achieve trimming? The current frames tamplate is

local options =  
{  
 -- array of tables representing each frame (required)  
 frames =  
 {  
 -- FRAME 1:  
 {  
 -- all params below are required for each frame  
 x = 2,  
 y = 70,  
 width = 50,  
 height = 50  
 },  
  
 -- FRAME 2:  
 {  
 x = 2,  
 y = 242,  
 width = 50,  
 height = 52  
 },  
 },  
  
 -- optional params; used for dynamic resolution support  
 sheetContentWidth = 1024,  
 sheetContentHeight = 1024  
}

What do I need to add to the frames to achieve trimming? [import]uid: 69481 topic_id: 23685 reply_id: 323685[/import]

I would love some help with this also - is it as simple as adding spriteTrimming = True?

Anyone??? [import]uid: 103802 topic_id: 23685 reply_id: 96267[/import]

Dear Ansca,

What about official statement or update of docs for this topic. I am also wondering how trimming works for new sprite API.

Thanks and regards

Just create a sheet with trimming enabled via texturepacker and then use the complex data format with image sheets api.

The latest texturepacker beta has an imagesheet export option. [import]uid: 118379 topic_id: 23685 reply_id: 103179[/import]

Trimming will just trim image transparency to reduce size of of each image in a spritesheet. [import]uid: 118379 topic_id: 23685 reply_id: 103180[/import]

The HorseAnimation sample code appears to have new sprite trimming implemented. Look at it. [import]uid: 44647 topic_id: 23685 reply_id: 103232[/import]

i downloaded the texture packer’s latest beta (3.0.0b8) and when i select the image sheet export option, the trimming checkbox is not available.
Any idea on what could be happening? [import]uid: 105206 topic_id: 23685 reply_id: 110127[/import]
