is5_PushImage

[kcarlino]

I'm using.

if (_is5_PushImage((BYTE *)image.pIPLSrcRGBA, image.w, image.h, 4, image.w * 4, (BYTE *)image.pIPLDstRGBA, 0, 0, &pFrom, &pTo, 0))
{
}

I was using the version 3 Push Image with no problem here and converted to using v5 and now it appears to be failing. Any ideas?

Thanks,
Ken

what does is5_GetLastError say ?

[kcarlino]

5 - IS_ERR_BADPARAM

I guess I'm doing something wrong.

what are the values of the parameters you're passing ?

[kcarlino]

pFrom.x = 644;
pFrom.y = 81;
pTo.x = 648;
pTo.y = 77;
if (_is5_PushImage((BYTE *)image.pIPLSrcRGBA, 800,600, 4,800 * 4, (BYTE *)image.pIPLDstRGBA, 0, 0, &pFrom, &pTo, 0))
{
}

Source and Dest pointers are valid and work with the IS3 version.

Thanks,

i'll take a look at the code and get back to you ASAP. (don't have the source with me at the moment)

the problem is that '4'. is5_PushImage doesn't work with RGBA images.

[kcarlino]

That's too bad. :-(

V3 (_ISE3PushImage) accepted RGBA images (sort of). Are there other ISE effects that don't accept RGBA buffers anymore?

I say sort of because I can see in my code that I handled v3 by adjusting the RGB values in my RGBA buffer by the alpha amount and in post filter reversing the adjustment so that I can successfully use these functions on RGBA buffers with the correct adjustment to the alpha channel in a indirect way. (yes there is some loss of color resolution with this approach)

yeah, "sort of" is right

i'll make it work with RGBA, no problem.

[kcarlino]

My vote is yes let them be accepted even if they don't process the alpha channel.

Thanks!

FYI: Here is a quick ScreenCast of the v3 PushImage working with RGBA buffers.

that's really cool

would it be OK if i linked to that from the ImgSource front page ?

[kcarlino]

Sure, no problem regarding the screencast. I've also set it to enable downloading the .mp4 file in case you decide you want to host it locally on your site.

Thanks for new release, will be grabbing it shortly!
