Damn, you´re right!

The golden word is StretchDIBits....
I´ve got the image as raw-array and converted it to an ImageID for other reasons. So, i´ve changed some code now, and it work!

Many thanks. I´ve spend hours for this...

This sample is better than mine
But it does always a black picture, because there isn´t a relation to imgDC.

I´ve tried with a 2nd Setobject to put the useimage-handle to hImg... nothing....

I´m getting confused too with handles, DCs, pointers, bitmaps....

Something like this for alpha-channel?

Thanks! I took the wrong constant in GetDeviceCaps...
And i´ve fixed the Scalefactor now.

And now, i know the reason:
When i use the first block (see code) with saveimage and loadimage_, then it works. - But i want to use the second (remarked) block with useimage.

Do you have an idea?!

Thanks @ all

I´ll take a look at the imgSource-dll. It sounds good. It´s relly important that i could save the images in *small* files.

@Sparkie - i´ve converted the images from color to bw/gray with PokeB and PeekB. (First allocate memorysize) Thats fast. I could put code here, if u want ...

Hello.

I´ve posted my problem in german forum too. But no answer.
Now, i hope here to get help.

My problem:
I´ve got a form with an image and some printer-settings.
The image can be resized to fit in page. But nothing occurs - my printed pages (Fineprint and epson-preview) keep blank.

Why?

Hi.

I´ve got 2 problems:

1.) How can i convert a 24-bit color bitmap (i´ve got it in a buffer and in a file) to 8-bit grayscale and 1-bit black/white image? Is there a fast solution? (perhaps assembler?)
I dont want to convert an 24-bit color image to a 24bit grayscale image :)

2.) How can I save ...

Wow, it work great!

Thanks you a lot!

Damn, i thought it

And how could i receive a dc from an image?

I had no results with GetDC.

Is there another way?


Thx.

Frank

Thanx a lot, it works fine!

But now, i´ve my second problem with image-handles :(

I want to copy 2 images into a new one:

Images 0 and 1 are given. How can i retrieve a handle on it?
Image 2 keeps black :(

What´s wrong?

id1=UseImage(0) ;image 200x200 pixel stored in image #1
id2=UseImage(1 ...

Why are the 2 jpg´s from the code different?
They should be identical.
Its only a sample code from my project.

hBMP.l=CreateImage(0, 200, 400)
dcv.l=StartDrawing(ImageOutput())
Box(50,50,100,300,RGB(255,255,255))
StopDrawing()

MemDC.l = CreateCompatibleDC_(dcv)
BitmapID.l = CreateImage ...

Hi.

How can I disable the systemmenu and all icons - except the minimize-button from titlebar in a window?

My program run in systray and the user should only minimize the window.

Hello everyone.

I´ve got a problem and cant solve it :(

I draw a normal box and an outlined box on a form.
Later, the normal box should contain a bitmap.
Then the user should mask a piece in it with the outline-box.
The mark (with mouse events) isn´t the problem.
The problem is, that the outline ...
