How did you get your bitmap?

Thank you for helping me figure this out, it is kind

The bitmap was generated from Lexikos & TIC's functions, such as



... it goes deeper into other related functions to pBitmap


G := Gdip_GraphicsFromImage(pBitmap)


;;; but what I want to do is turn the pBitmap into HEX BUFFER where it is appropriate and possible to do so can you please show example how to? ...

Unfortunately, I am not an expert in that. You have to ask those guys. The returned bitmap can be a C++ class or a structure, where the size can be calculated from the fields in the beginning. You have to know the size, when you want to convert the bitmap to hex.

Thank you for the insight there and idea. I will ask them to visit here, and maybe this can be expanded

How to retrieve bitmap data from a GDI+ bitmap: Advanced Graphic/Image question.

Thank you Lexikos.

Might you know a faster way to turn a bitmap into some kind of usable text code? I thought this hex conversion under this thread would be fabulous, ... though the Lexikos function does sort of what I am asking, ... it takes a darn long time to fully scan in even a small image before it is turned into text.

Are you using ImageData_GetPixel? Pass the ImageData variable to Bin2Hex instead.

Pretty cool Lexikos! I think I am almost there!, ... But how would I get the correct size of ImageData right for this function

Sweet

Lexikos - THANK YOU

i have just one more question. i get the flow of this now in terms of hex conversion, but question boggles my mind

1) what is IMAGEDATA, .. this is not a bitmap, or is it? not the same as PBITMAP or HBITMAP?

2) i am used to working with P & H bitmaps. may i ask, so i can see the end to end conversion, ... if IMAGEDATA is neither a pbitmap or hbitmap, what would be the step to take IMAGEDATA and convert it to either one of those?

1) ImageData is a raw bitmap - i.e. an array of 32-bit pixel data.
2) I suggest you post in a GDI+ related thread, or start a new one.
GDI+ has very little to do with this thread.

Thank you so much Lexikos. Could you please do me a favor a look at this separated thread? I've advanced it just a bit

Kind regards, glasso

Laszlo,
I am having some problems with the MCODE function, ... basically I am having trouble clearing it out. If I pass a variable that happens to be smaller than the last one, ... it actually leaves a ghost of the tail of the last variable passed in. I suppose in the loop when it allocates the memory, it doesn't do anything to re-initialize itself, assuming something else was passed in before

Do you know how to fix this somehow
