ImageLibEx library

[agraham]

Coredll.dll is the main device native code library. There is not a desktop version of it. The advanced drawing functions are implemented entirely differently on the desktop to the device, that is why there are two ImageLibEx libraries. The device needs to call native code for some things that are available in the .NET Framework on the desktsop. To implement gradient fill you will also need two different libraries or possibly one with conditional statements to do the right thing at runtime.

Thank you.

Version 2.1 now posted includes support for individual pixel alpha values so you can now blend images with alpha values, such as PNGs, and get proper transparency. See the "Alpha blending overview" in the help.

Thank you!

Where do you find the time (and the inspiration)? Any secrets you may share with us "normal human beings" to benefit from?

Retire early and keep body and mind active (I manage the mind bit anyway!)

Andrew,

Just used this lib for the first time and I can't tell you enough how happy I am with the pieces of art that you create.

A huge THANK YOU!!

Regards,
Helen.

Thank you for the latest library which helped me to solve the png alphabend issue. Hopefully you can give me some pointer how I can do the below:

I've 2 images to be blend together. The 1st one is a normal jpg (base image), and the 2nd one is a smaller png with transparent image.

I can blend them together using the AlphaPixelBlend. My question: is there a better way I can resize & crop part of the png before merging it to the jpg?


My current code seems to be a bit lengthy:
1. Resize the jpg to smaller (losing info) using drawerEx.DrawImage
2. AlphaPixelBlend the 2 images
3. resize it for display

[agraham]

The alpha bitmap has a width of mainimage.width/3 +1 and a height of mainimage.height. Using DrawImage you should be able to crop the main image starting at an x that is a multiple of three and crop the alpha bitmap to match starting at x/3 with a length of newmainwidth/3 + 1. As the vertical resolutions are the same use the same y start and height for both.

I don't think resizing will work without giving you some edge effects but you could try and see what it looks like.

Thanks again Agraham, I manage to get it work!

I thought a cirlce will be located at the very center, but result is different. it's moved to right-bottom a little bit.
What is wrong on my script?

Advise me, please...

'cvs: BitmapEx, drw: DrawerEx, pen: PenEx
frmMain.Show
cvs.New2(frmMain.Width, frmMain.Height)
xCtr = cvs.Width/2
yCtr = cvs.Height/2
pen.New1(cBlue)
drw.New2(cvs.Value)

drw.DrawCircle(pen.Value, xCtr, yCtr, 133)

frmMain.DrawImage(cvs.Value,0,0)
