Try to use HWND as argument of function and then take HDC from HWND...

I know that but isn't good. I must do it myself

Hi. I'm trying to write function to resizing images. Below is function which do that but only in x axis and scale = 50%, 25%, 12,5% etc. I need function resizing image in x and y axis with any scale....

Hi. How can I check number of memory, allocated by malloc() function ?

If you want to make winXP icons use photoshop with trial plug-in "iconbuilderxp"...

iconbuilderxp-110.zip

It's a code of function changing kontrast of bitmap. But it don't work that I want. Maybe someone saw how loooks changing contrast in PhotoShop. I want to reach the same effect... In attaching image...

yes yes it works :D at last :D thanks for help my master :D

I thought that it works, but it works only for mask with RGB(128,128,128).

Example

Bitmap RGB(185,185,185)
Mask RGB(0,0,0)
Background RGB(100,0,0)

RED (185 + 100) * (0 / 256) = 285 * 0 = 0...

it works :) thanks, I was looking for it, I didn't know that is so easy :) Big thanks my master :) ;)

but what if 12x12 pixel in the mask is gray ? it doesn't work...

first = bitmap
second = mask
third = background
fourth = last effect

I want to display bitmap using mask on every background

I'm attaching example
I tried to use ROP code but it doesn't...

I have one more question. I want to display bitmaps using grayscale mask.
I have 3 bitmaps.
First - created by epfTakeScreenShot
Second - mask bitmap from resource
Third - bitmap to display with...

You have right... I'll do that :)

epfTakeScreenShot Function works correctly, I tested it and display screens as DDB, but epfConvertDDBtoDIB don't work...

// epfTakeScreenShot.cpp

#include <windows.h>
#include "engine.h"

HBITMAP epfTakeScreenShot(HWND hwnd, int xPos, int yPos, int cx, int cy)
{
HDC hdc, hdcMem;

HBITMAP hBitmap;

Ok. I know what was wrong, before send pointer as function's parameter I must book memory...


BITMAPINFO * pbmiBk = new BITMAPINFO;
BYTE * pBitsBk = new BYTE[size];

But something is still...

Why?



BYTE * pBitsBk; // wrong ?
BYTE * pBitsBk = 0; // corect ?



It doesn't load DDB. I use it to Load DIB bitmap - API doesn't include it.

#include <windows.h>
#include "engine.h"

BOOL epfShowBitmap(HDC hdc, int xPos, int yPos,BITMAPFILEHEADER * pbmfh, BITMAPFILEHEADER * pbmfhMask, int iFlag)
{
static BITMAPINFO * pbmi, *...

Hello. (sorry for mistakes) I'm taking part of screen and saving it as DDB. And now I'm trying to convert DDB to DIB using GetDIBits function



int GetDIBits(
HDC hdc, // handle to...

thanks

Hello. I have a problem, I don't know how to take window's handle having device's context... If you don't understood me, I'll try explaine it more precisely...
