maCreateImageRaw problem

Hi,

maCreateImageRaw is not working on Motorola Xoom (HC 3.0.1) and MoSync 2.7.

When using transparent = false, color channels are inverted.
When using transparent = true, image is mixed w/ last canvas used and color channels are inverted.

Everything is ok on Froyo 2.2 and GB 2.3.
MoSync 2.6 is ok on all versions, including 3.0.1.

Regards,

Diego

Hi,

I found the same problem using MoRE.exe + TeamViewer (Yes, I was remotely showing a feature to a customer).

So the problem is probably in RGB888 -> RGB555 convertion.

Hi,

Do you think this issue is going to be solved in 3.0 ? Do you have a workaround?

Sorry, no I don't think that has been fixed. Will talk to the dev team about the status of the issue.
Best, Micke

Hi Micke,

is it possible to get a data handle instead of image handle from an image resource. If so, I could embed my own png decoder to workaround maCreateImage problem.

Hi, if the image is added to the project as a binary resource (.bin) instead of an image (.image), then the resource will be the undecoded data. Also, if you download the image data without using the ImageDownloader class, then the data handle will be the undecoded data.

Hi Sam,

I was afraid that was the only solution.

Mike,

I've implemented the workaround using lodepng + Gfx_Plot, but it's really slow. I'm creating buffers of raw images, but it's really hard to use w/o the createimagefromraw. Any chance in correcting to the next release?

Hi Micke/Florin,

Good job!

Last NB (2012-03-29) corrects RGBA channels in maCreateImageRaw, but it only works with opaque images. I guess there's a problem w/ maDrawImage. Attached what I expect and what I have. The transparent part is not merging w/ current background, but with some buffer or so.

Regards,

Diego
