2DDrawing

Num3 · Post by **Num3** » Mon Dec 01, 2003 1:48 pm

Would be nice to have a few more commands to the 2DDrawing set.

CopyImage(#originalimage,#newimage[,x,y,w,h])
copy and / or crop a image into a new image

Drawimagemasked(#image1,#maskimage1,x,y)
To draw a masked image

This would be very handy to make games, without DX

using only regular 2DDrawing commands

Yeah, i vote for Drawimagemasked(#image1,#maskimage1,x,y)

An additional parameter to convert the depth would be also fine

What about that?

Copyimagefromadress(imageadress,#newimage)

Could need it for images from the Clipboard

You can get the adress of an image, which is Copied, but you canÂ´t use it
There is no possibility to get the width and height without the Api or something like this

What you say is already provided with CatchImage()

...or GrabImage(), CatchSprite(), GrabSprite().

These 2 are now 2Ddrawing functions... So they miss the purpose!

Num3, i just answered to Franky. Perhaps Franky wanted to manage Screen 2D graphics images in realtime.....

Sorry, i understood something else

But that is the idea behind this request, to use only 2D commands to do more powerfull things in a image

What you say is already provided with CatchSprite(), GrabSprite().

So,if it is, why doesnÂ´t this work?

Code: Select all

CatchImage(1,GetClipboardData(#pb_clipboard_image))
SaveImage(1,"test.bmp")

Copied an image from a directory :"Pointer is NULL"
Made a screenshot: no debuggermessage but a message from windows;
Windowsproblemmessage(in german:
Windowsproblembericht")

Mmmmh, well, i've never understood what means "handle" for microsoft terminology. I thought it is a pointer, but i was wrong.

Anyway, now the question for you is: how to get a pointer from a image handle?

The API command
BitBlt(DC1,x1,y1,wd,ht,DC2,x2,y2,mode)
allows copy of part of an image into another image.

But I agree that a Purebasic "wrapper" on this command would be useful because it would remove the hassle of creating, releasing and deleting Windows device contexts.

Also, I prefer to avoid API and assembler where possible so that my code is simpler, more portable and future-proof.

Hi

the question is not how to get a pointer from a image handle, i think the worth given back by getclipboarddata() is the same as Useimage(), so i could drawthe image into my own image(?)

the question is how to get the width and height of the image

Then with an inverse fuction of ImageID() that would be made.
