Just curious ... BMPsave

[Gordon Rahman]

Why do we have:
getBMP .. loadBMP .. drawBMP .... unloadBMP and  

BMPsave? in stead of saveBMP?
Something to do with BMPbutton?

If I could go back in time and ask my younger self...

Very good remark Gordon. It is not logic and rather confusing. I will try to propose something.

Hello Frizhd

I think that Carl is a genius. He problaby used SaveBMP.
But then he expanded his SaveBMP and called it BMPsave.
So now we realize that SaveBMP differs from BMPsave.
BMPsave takes care of a problem.

Try to split a picture (bmp) in 4 evenly peaces. Now save
the four BMP and get them back and place them to resemble
your original large BMP. Now you will see why Carl is a genius.
Because while every BMP has his own kader-line, the total picture
still will show single lines!

So BMPsave works different then when creating a box.
You have to position your cursor and ... give the LENGTH and WIDTH
of your BMP to save in stead of the X-Y coordinates across the diameter.
LibertyBASIC will take care for you ....

It would be easy for Carl to use 1 routine with 2 names.
Let's say BMPsave and or SAVEbmp with the same routine (methode).
But thanks to Carl LB takes care! for placing BMPs next to each other
with a single kader-line when saving with BMPsave.

So now we "learn" that BMPsave differs for a reason.

You're probably right about our remarkable whizkid, Gordon. It is admirable how Carl has invested his best efforts in LB and is admired by many. Hope he will be able to complete FIVE once in the rest my lifetime and I may have still profit of it. An almost inhuman task, which must put a lot of pressure on Carl and his One-Man-shop. No small-talk this job. He deserves our support. May he finish soon and complete it. Thanks to all supporters. I realize, Gordon, you are a long lasting pillar and we know to appreciate your many contributions.
I am certainly one of the less intelligent supporters. I have been using LB4 for years. There are a lot of things I don't understand and confess to be unable to get involved in those difficult matters. I get no insight and overview, while I am a passionate fan of BASIC for over 40 years. Is it me or the structure and representation of this forum? I don’t get in!
And: after this, your explanation, I lost complete the understanding of our specific subject.
Doubt whether it makes sense to present my proposal for an adjustment here. Friz.

Hello Fritz,
I realize that I had better answer your remarks private.
Two things here. Kader-line should be borderline. And Fritz seems (German) for Frits (Dutch) ...

LB5 for Microsoft Windows .. just need 27 commands to finish (really easy ones too). But Carl wants to deliver
the Android version at the same time.

In Holland we still have the HCC (Hobby Computer Club). Nowadays less then 150.000 members.
Their Programming Interesses Group is very active. (6 online sessions per week included with 1 special LB session)

I'll mail you here.

Friz, make your proposal. The difficulty will be changing the syntax now and spoiling old code.

However discussion is good. I was thinking that some commands act on the bmp resource itself and some commands act on a graphicbox. So I was thinking BMPx when we are creating or acting on a BMP and xBMP when we are drawing or acting on s graphicbox.

But I can live with what we have!

[frizhd]

I still need some time to let it ripen. Using other graphic formats such as JPG will determine much later in time whether LB continues to appeal to young people. Handling images is very important.
Of course it must be an addition, because compatibility with old listings is a strict requirement.
The BMP format, the resolution and the enormous memory consumption requires something with a vision for the future....

[Rod]

The thing about BMP is that it is the native Windows format. No matter what the image form if you are looking at it on screen it is a BMP. And more, any on screen manipulations must be in BMP form. That’s how the blitter works and the blitter is being used in the background even for native commands.

So the benefit of jpeg and such is just the initial storage. JPEG is also pretty poor at preserving pixel detail which is often important in computer graphics. When you zip a BMP you get pretty good pixel perfect compression.

So BMP is a natural choice for computer graphic storage. It would be cool to have a native command to load other formats. But once loaded they are only of use in BMP format.

Just making the point that BMP is not a bad format. But I entirely agree we need to be able to load other formats easily. Fortunately LB5 can.

[frizhd]

May be I understand you well, Rod.

There are two things that we must clearly separate.

1. How does LB deals with all kinds of imageformats. It is the conversion problem.
Internally LB and all actions it remains the BPM. Clear, no discussion about it.

2. The relationship with the programmer's language, the GUI with a difficult word. How should a person code his statements?
Hope I have something to comment and recommend about this second subject.

I am Dutch, have to communicate in English with the forum. Very difficult. BASIC is the language to communicate with the computer. I concentrate on the statements, commands en keywords.
