I don't see a problem doing that either. I think you need to post a zip of your app directory with libraries, code and images and a step by step description of how to demonstrate the problem.

Here it is
1. open form designer
2. click on image
3. click image button select image Softsect
4. view image in designer dont close form1
5. click image button again and select image softselect new logo
and then the error comes up (see Error screen shot)
could it have something to do with my path its quite long
d:\alldata\basic4ppc\softselect code\bitmap test\
Thanks again
You are a star

Hi,
no problem with V6.5 and XP Home SP3. Maybe rename your file to softselect_new_logo.bmp

I have tested it, works fine, without any problem ?
Even with your long directory name.
Try perhaps to remove the blanc charactes in the filename ?

Best regards.

EDIT: Hi wolfgang, you were faster than me !

[Softselect]

I tried that, no luck
I have XP Prof SP3 and V6.5
the funny thing is if i delete the image from the app dir and load the same file from a different directory it works fine
Strange things happening, maybe its got something to do with the heat in South Africa 33c here today
Thanks Friedrich

No, I can't get it to go wrong. I've even replicated your paths on my D: drive. Interestingly in the background of the error screen shot it looks like the correct image actually is loaded. Is it possible that the image file is open in another app like an image editor? Also if you reboot and try again does the error persist?

I have a strange problem which I can't solve. I loaded the 1.2 version and stored it in the library directory (with the cs and help)
If I start a new program and use it - everything works fine.
If I add the dll to my existing GPS program - I can't get the RotateHQ and RotateFast, as if I use the previous version.
Is there interference with the other libraries ?
see attached list

I've had a quick look and can't see what might be a problem. I am afraid you will have to post the source that shows the problem so that I can have a better look.

In the directory of the program I had the previous version dll.
Loading the library from another source (the basic library directory) didn't copy the new version, and the program used the old, which does not have these two functions.

I think that it should have copied the selected library even if a library with the same name exist, but that is not the problem of this specific library.
Thanks.

Version 1.3 now posted with a single new method in BitmapEx - AlphaBlend. This allows a specified portion of a source bitmap to be blended with a destination bitmap using a specified transparency value. Optionally a colour in the source bitmap may be specified as transparent and hence not blended with the destination. This needs .NET 2.0 but will work on both device and desktop.

Note that this does not cope with images such as PNGs and GIFs that have individual alpha values for each pixel. I had initially hoped to do this but it would only have been available on WM5.0 and later on the device. Implementing this would have required native calls to the Windows GDI on the device as the Compact Framework does not support this. In the end the grief involved in getting it working properly, mapping it sensibly into ImageLibEx for access from Basic4ppc and implementing a desktop compatible version was just too much effort to be regarded as fun so I rolled my own implementation with direct bitmap pixel manipulation . The upside is that this works identically on device and desktop and doesn't require WM5.0 or later and so runs on any device that can run .NET 2.0.
