I'm having problems loading 1bit and 8bit bmps. The colors don't load correctly.
With 1 bit images, I get big black vertical lines down the image. For example I use this image:
It comes out like this when i load it:
For 8 bit it comes out as a monochrome image, usingblack and whatever color.
I used this image:
I comes out like this:
The code I used was this:
>
if (image.bpp == 1) {
palette = new unsigned char[2*4];
fread(palette, 1, 8, file);
unsigned char imaged[infoheader.imagesize];
fseek(file, header.offset, SEEK_SET);
fread(imaged, 1, infoheader.imagesize, file);
image.image = new unsigned char[(infoheader.imagesize*8)*3];
for (int i=0;i<infoheader.imagesize;i++) {
for (int j=7;j>=0;j--) {
int set = ((int)imaged & (2^j)) >> j;
image.image[(i*24)+((7-j)*3)] = palette[(set*4)+2];
image.image[(i*24)+((7-j)*3)+1] = palette[(set*4)+1];
image.image[(i*24)+((7-j)*3)+2] = palette[set*4];
}
}
} else if (image.bpp == 8) {
if (infoheader.numcolors == 0)
palette = new unsigned char[256*4];
else
palette = new unsigned char[infoheader.numcolors*4];
fread(palette, 1, infoheader.numcolors*4, file);
unsigned char imaged[infoheader.imagesize];
fseek(file, header.offset, SEEK_SET);
fread(imaged, 1, infoheader.imagesize, file);
image.image = new unsigned char[infoheader.imagesize*3];
for (int i=0;i<infoheader.imagesize;i++) {
for (int j=i*3;j<i*3+3;j++) {
image.image[j] = palette[(int)imaged*4+(j-(i*3))];
}
}
}
Anyone know what I'm doing wrong, and how i can fix it? By the way, I'm reading the data into 24 bit data. Thanks in advance
