Hi!
Im working with C++ & win API32.
My Problem:
I have in a matrix of unsigned chars the colours (in RGB format) of
an image. The dimensions of the image are 720 x 576 (cols x rows). So
the size of the matrix is 720*576*3 bytes (unsigned chars).

I am loading a 4X5 picturebox matrix using a bitmap file template. As each
cell in the matrix is being loaded, I append a text string using the
DrawString function to complete the cell's image.
The problem is that the DrawString function seems to work only on the
desktop and not on the hx4700.
Does any body know how to get around the DrawString to draw a string on a
bitmap image at runtime?

Hello,
I am using a 2-dimensional matrix for image manipulation and recognition.
The x-axes is image.width pixels long and the y-axes image.height.
All fields have a RGB integer value.
To store this value from the image into the matrix I am using the
bitmap.getPixel(x,y) method because manipulating values in the matrix is
much faster than using the bitmap.setPixel(x,y,color) method.
My problem is, that the getPixel function is also very...

Hello all,
I am currently implementing a fairly simple algorithm. It scans a
grayscale image, and computes a pixel's new value as a function of its
original value. Two passes are made, first horizontally and second
vertically. The problem I have is that the vertical pass is 3 to 4
times slower than the horizontal, although the code is _exactly_ the
same in both cases?!
The code itself is very simple. There are 2 loops to scan through...

Hi all,
I need to change image's size by GD in PHP. An fix image at the first layer, the second layer has an transparent image with white background. We can't see this white background because I did:
$trans = imagecolortransparent($layer_2,$white);
There are 2 buttons "Zoom in" and "Zoom out" that user can change image size whatever they want. My problem is:
After changing the first time it's fine. Continue to change one more time the...

I seem to be able to do this with the TRIAL version of Aurigma
Graphics Processor in ASP. However the trial version leaves a horrible
square randomly on the image. (Obviously a limitation of the trial
version)
They have discontinued this product and therefore cannot purchase it!!
Anyone know of any other ASP Image tools that cos Remove Noise or De-
Speckle an Image? I have tried about 8 different ones with no luck!!

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...
