how to cut a bitmap?

[dedndave]

you could Also recode documents and asm's that are in other languages and than use Google translate to translate them  :wink

Good idea :U I have a 700k Basic source, will see if Google translate can port it to Masm :toothy

Notepad2 looks ok, but I am always surprised how different views are what constitutes a good editor. For example, my recent files list has 20 entries - N2 does not even have one; and no bookmarks, and apparently (?) no F1 that opens to Win32.hlp etc... on the other hands, it has settings for long lines, and the wndow title display can be configured ::)

google translate will waste no time in telling you that it's too big   :P

[jj2007]

You have to enable the setting in Notepad2 to save recent files; Settings > Remember Recent Files.

Greyed out in the version that was attached above.

* Notepad2 as notepad replacement (extremely light-weight. It would not be really suitable for the F1 > win32hlp thing that you are looking for)

632k=12*RichMasm - the latter is really light-weight although it does include the F1 thing :bg

i have been playing with loading a transparent PNG strip and splitting it up   :P
not as easy as it should be - lol

anyways, it dawned on me that they don't need to be PNG's, nor split up

64x64 icons under XP....



let me owner-draw the last box, then i'll post some code   :bg

 :clap:
thanks a lot dedndave, for teaching  :toothy

[RHL]

dave, the file is damage :P

EDIT:  this is the png file right?  :]

[dedndave]

it is a PNG file - save it, then remove the .ZIP extension by renaming the file   :P

thanks a lot dedndave, for teaching

i am learning, too   :U

ok
i am not getting what i want out of the owner-draw thing   :(
during WM_INITDIALOG...

Code Select Expand

            INVOKE  GetDlgItem,hWnd,IDC_STC5 ;ebx
            mov     hStatic5,eax
            INVOKE  CreateSolidBrush,000000FFh          ;COLORREF = red
            mov     hBrush5, eax

then, during WM_DRAWITEM...

Code Select Expand

        mov     edx,lParam
            .if [edx].DRAWITEMSTRUCT.CtlID==IDC_STC5
                .if [edx].DRAWITEMSTRUCT.itemAction==ODA_DRAWENTIRE

                    ;draw stuff here
                    INVOKE  SelectObject,[edx].DRAWITEMSTRUCT.hdc,hBrush5

                .endif
            .endif
i will figure it out, tomorrow   :P

in the mean time, i know you want to play, so i'll post what i have...
(this is a real ZIP file)

[RHL]

dave a question :D
always I like the way your programmed, I want mean, only the asm file, if depends exist also ( you do not use a IDE ) use.. notepad...? wft? notepad... lol
and for assembled a .bat file :D you do it? or exist a program for make it?

I will learn to no depend to a IDE, i like :D

[dedndave]

well - i should have a little program to set up my projects, huh   :U
but - i use Notepad to edit the batch file - using Find/Replace   :P

the "if not exist" - i do that so if you are not in the right folder, it won't delete any files

as for IDE's...
i might learn to use Ketil's RadAsm and ResEd - it looks pretty nice   :U
for now, i am still learning windows - lol

i came from the days of DOS
batch files did a lot of our work for us, back then - if you knew how to write them

[dedndave]

ok
if you just want a static control with a solid color (and text, perhaps)...
the easy way is to handle WM_CTLCOLORSTATIC



if you want to paint something more, we will have to do owner-drawn

Hi,

Ive been looking through this code and other examples and trying to load part of bitmap image onto a static control so that i can use scroll bars to move up, down, left or right and view the bitmap inside this little viewport. Does anyone have any examples of this, i tried converting this example i found (http://www.codeproject.com/Articles/3175/Displaying-Bitmap-with-Scrolling) to asm but didnt get any success.

The code i do have is a complete mess, from trying various things, copy and pasting other code from other examples and trying out things, but without any success. Here is some of it, might help someone to do a proper conversion or point out where ive gone wrong. Thanks

i have never tried scrollbars inside a static   :P
no need for it to be a static, either, i suppose - it could just be a window
let me play with what you have....

off hand, the advantage of using a static is that it would size itself to the bitmap
that doesn't seem desirable, in this case

Hi Dave,

My original plan was to allow for a map editor of sorts for baldurs gate games. If the main map is say a bmp and is easily loaded, i wanted an interface that allowed scrolling around the full extent of the bitmap within the window (or static control as i tried) but any solution that achieves the same result would be ace.

Once id got that far (which i havent :D) i thought i could create little static controls ontop of the map which would be points of interest, destinations or whatever. These could be clicked on to give properties that could be edited (in another side window or something like) and would show position (x, y on the map), name and other details and id also thought i could move these statics around as well (updating the internal files reference values for these places) with some sort of mousemove override. I thought to do a simple STM_SETIMAGE for these little map markers, could be little icons, or red squares or anything tbh that would allow an easy way to manipulate these items for the end user.

Anyhows, it looks like it was more difficult than i first thought. The basic load bmp and scroll it around has me stumped so far, let alone the other stuff. I suppose that putting the image in its own window with its own scrollbars allows the system to control the scrolling, so that might be a better solution and i could create a seperate window for the 'properties' thing later on.

Any ideas/solutions or whatever stuff you can come up would be great.

Hi I saw this thread and I remembered something that I was trying to do a while back ... http://www.masm32.com/board/index.php?PHPSESSID=bbc80810adc7b9ae86e1d81de57aa675&topic=17303.msg145116#msg145116

I was trying to cut a bitmap so I can load it and scroll it ...is it possible to define each image in the data section?

[dedndave]

i will play with it over the next few days
as for the little "markers", you could just make them buttons   :P
only place the ones that are in full view
hide the others, or perhaps, create/destroy them as needed

i have some code that i use for scrolling a window that holds text
i use the same code for horz and vert scrolling
and - i have mousewheel code that works similarly

i have a couple questions...

what size is this little window (either with or without the scrollbars) ?
how big is the overall map bitmap ?
is the window sizable ?

i have never tried using my scroll code for an image - might be a fun project

[hfheatherfox07]

there is an example in the last post on my thread .... http://cyberdoomsystems.narod.ru/ripp/about.rar

I am still working on that enumerate windows app.....almost there  ::)
