This question is tagged "C++" and "C++11", so this example uses the C++ std library for file output, and doesn't use malloc.

If you also do not see the error, you could check for differences in each binary output to pinpoint the problem.

#HYPERSNAP PNG INSTEAD OF BMP WINDOWS#

The bmp file created by this example works fine with the image viewer packaged with my Windows 8.1. The error you see is probably not caused by the QR-Code library, but rather something in the bmp file code.

#HYPERSNAP PNG INSTEAD OF BMP CODE#

Here is a code example which dumps a 24 bpp bmp file created from a QR-Code. Whenever i'm opening the bmp file it says:Īnd is it possible to save to png instead of BMP? *if (((f = fopen(OUT_FILE, "r")) != NULL))įwrite(&kFileHeader, sizeof(BITMAPFILEHEADER), 14, f) įwrite(&kInfoHeader, sizeof(BITMAPINFOHEADER), 40, f) įwrite(pRGBData, sizeof(unsigned char), unDataBytes, f) īut somehow this creates a BMP with corrupt headers. PDestData += 3 * OUT_FILE_PIXEL_PRESCALER *(pDestData + 2 + n * 3 + unWidthAdjusted * l) = PIXEL_COLOR_R *(pDestData + 1 + n * 3 + unWidthAdjusted * l) = PIXEL_COLOR_G *(pDestData + n * 3 + unWidthAdjusted * l) = PIXEL_COLOR_B PDestData = pRGBData + unWidthAdjusted * y * OUT_FILE_PIXEL_PRESCALER įor(l = 0 l < OUT_FILE_PIXEL_PRESCALER l++)įor(n = 0 n < OUT_FILE_PIXEL_PRESCALER n++) KInfoHeader.biHeight = -((int)unWidth * OUT_FILE_PIXEL_PRESCALER) KInfoHeader.biWidth = unWidth * OUT_FILE_PIXEL_PRESCALER KInfoHeader.biSize = sizeof(BITMAPINFOHEADER) KFileHeader.bfOffBits = sizeof(BITMAPFILEHEADER) + KFileHeader.bfSize = sizeof(BITMAPFILEHEADER) + If (!(pRGBData = (unsigned char*)malloc(unDataBytes))) UnDataBytes = unWidthAdjusted * unWidth * OUT_FILE_PIXEL_PRESCALER UnWidthAdjusted = (unWidthAdjusted / 4 + 1) * 4 UnWidthAdjusted = unWidth * OUT_FILE_PIXEL_PRESCALER * 3 If (pQRC = QRcode_encodeString(szSourceSring, 4, QR_ECLEVEL_H, QR_MODE_8, 1)) Unsigned char* pRGBData, *pSourceData, *pDestData Unsigned int unWidth, x, y, l, n, unWidthAdjusted, unDataBytes This creation is working nice but how would one output the qrcode to a BMP file within c++?Īt this very moment i have this code: const char* szSourceSring = QRCODE_TEXT He is able to set the defaults for JPEG and PNG files.I'm creating a qrcode with the library qrencode.h

#HYPERSNAP PNG INSTEAD OF BMP WINDOWS 10#

I just spoke with a co-worker who also upgraded his Windows 10 VM to Windows 11 and he does not have this problem. The question is, "is this a bug or a feature?" It seems like these file types are "locked down" and are allowed to be changed. With PNG and JPEG, the button for "Change Default" does not exist in the Windows Properties dialog. With other file types, such as TIFF and WEBP, there are options for setting the default within the Windows Properties dialog, Open With, and Default Apps. It does not set the default.ĭigging around, I've discovered that this applies to PNG files as well. If I choose another app, it opens with that app, but only once. Selecting "Open With" does not provide an option to set the default. Some details about this computer: I am the administrator, it is not connected to an Active Directory domain, it is running as a VM that I remotely connect through either a) Spice, or b) Remote Desktop Is there another settings page that would allow me to change this default? If Microsoft "hid" this, or if this is a bug, is there a registry setting that I could modify to change this?

If I go through all of the apps, including "Photos," that might be the default, JPEG is not an option. If I scroll all the way to the bottom to change it for the specific. However, there are no options in the "Default apps" settings page for JPEG images and file types. I would like to change it back to JPEGView.

Photos takes a while to open and JPEGView opens much more quickly. jpeg) was changed from my preferred program of JPEGView to Photos (Windows default app). My computer was recently upgraded to Windows 11 and my default program for JPEG (.jpg.
