Concatenate PNG images in memory (and libpng is not an option)

Hello to all! Well, I want to read some PNG files of 256x256 and concatenate in memory (I dont want to save in disk) for display and some live transforms as a zoom or navigate in. The problem is, I know how to do with libpng, but Tizan has not libpng, and I can not find information about how to do with EFL (I could only load and display...).

Any suggestion?

Thanks to all!

Hi!

Do you want to perform live transform(i.e. navigation) on the concatenated image or on every single one while they are being viewed as a concatenated one ?


You can try to load more than one images in a canvas using evas_image_file_set(). For zooming evas_object_image_load_scale_down_set() or evas_object_resize() can be tried out.  *img object in Evas supports png format.

 

Thanks.
