Resize and Copy

[tomczak]

I just discovered a nice feature: Right click on the image window/Resize and Copy, which makes it really easy to copy images in progress to other applications.

One observation: if the image is 48bit, it doesn't automatically converts it to 24 bit like saving JPGs off 48 images does.

Cheers!

Maciej, thanks for sharing your discovery, indeed very useful.
Another thing i noticed is that it looses all exif data, and more important, it's setting of the colorspace.
Means if you copy a image in Chrome 2000 D65 it comes out very dull,
Transformation -> Color -> Profile - Output Profile: Chrome 2000 D65 and Change: Profile settings only brings back the original CS settings.

The Resize and Copy is meant to be a convenient way to get images to the clipboard to paste into other applications, such as emails, and web posts. The resize option was added to make it quick and easy to scale images to sizes reasonable for such applications. Auto conversion to 24 bits would be nice addition-- I'll add it in the next release.

Kiril,

Would auto - conversion to sRGB be a option, too ?
If one uses a workspace like Chrome2000 or AdobeRGB it would always require a conversion to sRGB in PWP, before.

Since the standard clipboard image does not specify color space, perhaps we should always convert to srgb on copy. Can anyone think of any cases where that would not be desirable?

If you place the CF_DIBV5 format with the bitmap color space information in the clipboard, the system will convert the bitmap bits from the bitmap color space to the sRGB color space when CF_DIB or CF_DIBV5 is requested. If CF_DIBV5 is requested when there is no color space information in the clipboard, the system returns sRGB color space information in the BITMAPV5HEADER structure. Conversions between other clipboard formats occur upon demand.

Do I understand that correctly that images in the clipboard should always be converted to sRGB?
In PWP we do have the better CMM then Windows have, don't we ?

Sorry for re-opening an old topic...
I hadn't really noticed this very handy shortcut for quickly saving a current in-process image, but some remarks anyway: 1) color space conversion is important, and sRGB is the simple choice (not just email, but e.g. for rapid sRGB preview purposes), any other target space is best handled by an explicit conversion transform; 2) for preview consistency, make sure to use the current user-selected CMS engine in use does the conversion, e.g. I notice that the LCMS engine does a far finer job on dark shadows, so letting the clipboard use the default Windows CMS (via the clipboard) would probably be a mistake in that case.

The next release will place images on the clipboard in both BMP format (no profile, 8-bit only) and BMP V5 format (includes profile and allows 16-bit, but no EXIF). This will let programs that can handle BMP V5 (including PWP) copy and paste with fewer restrictions. Programs that cannot handle BMP V5 format will still be able to access the BMP format version.

O.K., but is it too complicated to do the color space conversion to sRGB with the CMS the user configured in PWP at whatever bit-depth the source image may be, and then place that sRGB converted bitmap on the clipboard with the right parameters--so that it does not undergo color space conversion a 2nd time?

Will take a look at that - shouldn't be too hard.
