Hello Mike,
Thanks for the fast reply.
I'll do what i can to explain myself, sorry if my english is not accurate.
I was confused about dpi, I usually work with prints and now I'm changing my line of work to mobile games, sorry for my misunderstanding. You are right, the dpi data is irrelevant in screens. The problem is that when I export my frames to png in spriter at full size or I resize the project I see a little "blurry" effect on my frames or modules. At first I created my frames directly with art applications (one by one frame animation, old style), and when I switched to spriter I was amazed how easy and intuitive was to create the animations, but unfortunally I also found that the images were not as well defined as they were before with the art program. When I searched for the diference between the original png and the spriter generated png I found that the dpi has been reduced from 300 to 120. I thought that was the problem, my fault :oops:
Maybe in order to optimize the images (file size), spriter process them and reduce the image quality a little bit, I don't know. I see a quality diference between art program generated sprites and those spriter create, specially when I work with low resolution images for small screen phones. With Texture Packer I can optimize (lower) the image quality of png, so my guess is that spriter is doing it on it's own.
For now I'm resizing the project in spriter, because I have to work with diferent resolutions for diferent screen phones. Then I take the original images of the modules (head, torso, arms, etc...), resize them with an art program, and use them to replace the spriter generated images. This way I can have better quality modules, but exporting to png still reduces the image quality of the frames. However, if I do it this way, the quality of the frames is not as low as the one I get if I use the modules that spriter generate when I resize the project, maybe because it just optimize the files once, not twice (once resizing and then again exporting).
I hope Edgar can find a solution for that.
Thanks again. :D
