Transparent...

[Arie]

Hi!

I want to ask something that really
bugs me!
How can I do that when I put an icon
in a picturebox and some part in the icon is
transparent. but the picturebox has his backcolor
that bugs me.
can I remove or change that backcolor to transparent?

Thank you anyway,
Arie.

You can, but it's easier to use an Image instead...

[Arie]

Yeah, but Image is not like a picturebox.
I can't use in Image the PaintPicture.
I need it for a smooth animation.
If I use Image it do flashes in the image
and it's very ugly for my game.
Are you sure that there isn't any way to
make the BackColor transparent?
Maybe it's like how I make a form transparent?
I don't know!
If you know, answer...

Thank you anyway,
Arie.

Try painting the image to the form, at a certain position (all you gotta do is experiment a bit with the X/Y coordinates of where you paint it). See, no need for a picture box - because it doesn't support transparency!

[Fox]

If you really need the picture control properties you can also use my sprite control (download at my page). You'd say it's a picture boy with transparency...

[Arie]

Hey, Fox!

I have two questions for you:
1) Where in your website is this control that you said?
2) Does it act like a regular PictureBox, with PaintPicture
and everything?

I need that because of the flahses that I get from the
Images when I switch pictures quickly.
I tried PictureBox and It's really good.
But I need a PictureBox with Transparent BackColor
like in the Image Control.
Understand?

Thank you anyway,
Arie.

You should use your own routines with BitBlt instead of moving he image control, which causes FLICKER!
When the image control contains a big transparent picture, then you get even more strange effects while loading the form.
So, work with BitBlt, memory DC's (which contains for example the complete background).
To get rid of the flicker, you should NOT replace the whole transparent picture with the background, because that's the flicker effect!
Instead, only BitBlt the background above the parts between the old XY position and the new XY position of the transparent image. So, only the borders are restored with the background (which are mostly small when you're moving pixel by pixel) and THIS REMOVES THE FLICKER!

I don't know if it supports PaintPicture, I never really used this function.. you can download it here (http://orion.spaceports.com/~mccloud/coding/graphics/sprite.zip).

To Mad Compie: My sprite (transparent picture control) does not flicker.

[Arie]

I downloaded your control from the link you wrote
and this control does not support the transparent of
the ICO files!
I need a control that supports that and does not flicker!
It's driving me crazy!!! It can't be that that control
doesn't exist!
Auuugh!

THANK YOU ANYWAY,
ARIE.

Use my sprite control - you can select which color you want to have transparent...

[Arie]

How I select the color of transparent?
But you know what? when I put the Icon in your control
the transparent looks in purple. is this the
transparent color?
Explain more...

Thank you anyway,
Arie.

[Fox]

Yeah, the default transparent color is purple indeed. I dunno if you can really change it, it's an old control... if not just use purple ;)

[Arie]

So... I can draw ICO and BMP files with a transparent
purple? and then it will be transparent in
runtime?

If yes, thank you for all the help,fox.

Talk to you in the next problem...
Arie.
