Adjusting on screen image

[varcarme]

I'm wanting to allow the user to make some adjustments to the on screen image (brightness / contrast etc) but I'm have a few difficulties getting the adjustments to appear without first saving and reloading the image.

Code: Select all


oImage = CREATEOBJECT("gdpicturepro5s.imaging")

oImage.SetLicenseNumber("1234")

oImage.CreateImageFromFileICM("c:\xxx.jpg")

oImage.SetBrightness(10)

x=oViewer.SetNativeImage(oImage.GetNativeImage)

&&& x always returns 2 (invalid parameter)



if I use iImage.SaveAsJpg("c:\zzz.jpg") then oViewer.DisplayFromFile("c:\zzz.jpg") it works but this is so much slower.

Still can't get this to work I'm afraid....

I tried to use Viewer.DisplayFromGdPictureImage(Imaging1.GetNativeImage())

This also returns an error 2 (wrong parameter)

I've tried lots of different images but always get the same result.

I'm really confused

Hi,

I can suggest this:

- Check oImage.GetNativeImage returns a value <> 0
- Check the oImage objects is created from the same library as oViewer

If you meet these 2 conditions, your code should work.

Kind regards,

Loïc

Thanks Loïc

I think it must have been an old viewer component I was using.
