Hello Y'all:

Anyone know why when I load and paste a bitmap, it appears approximately 1/4th the resolution of the file?

could be the resolution of your display mode, or if you are using get image from the bitmap, check the texture flag.

Hello Ortu:

I'm just doing a load image...paste image...Program is running Windowed in a 640x480 Window, bitmap is 400x200 resolution. I tried BMP and JPG - same result on both.

Ortu is suggesting you check the texture flag on the load image command. You do something like load image "bob.bmp",1,0. The additional zero tells DBP not to treat it as a texture, so it won't be resized and should stay the same size.

Hello Fallout:

I already had the ,1 at the end, adding the ,0 (i.e. ,1,0) made no difference. The image is the same size, just not full resolution/is pixelated.

Hello Fallout:

I made you a great screenshot. See attached. All I did was go into Microsoft Paint, select text, set the font size to 72 point, and type "Hello". In my program, I made sure it was set to run in a 640x480 window, and imported my Hello.jog file. Here's the code to display it:

load image "media\Hello.jpg",1,0
paste image 1,0,0
input a

As you can see from the screenshot, it is exactly the same size (no foolery going on), yet the image is about 1/4th the resolution of the original.

The first font looks higher than 640x480. In Photoshop, fonts are allowed to float over the screen resolution, so are much higher than the screen resolution. I suppose that Paint might do that as well.

Hello Pincho:

Try it yourself - I had full instructions...If the font was higher resolution than 640x480, the window would just clip the image. But the image I am having a problem with is definitely 400x200, in a 640x480 window...

Are you sure your window resolution matches the desktop resolution? On my PC the window seems to be stretched somewhat which causes the "Hello" image to be stretched and filtered as well.

Hello Green Gandalf:

The window does appear to match the desktop resolution on mine.

The texture flag should be one not zero, ie.

OK I tested it in lots of ways, and they were all fine until I tried Full screen Window exclusive. Then it was like yours. When I examined full screen exclusive it was 16 bit, so the AA was lost. All you need to do is change it to 32bit.

Sorry. I assumed you were using the bitmap commands:

Quote: "Anyone know why when I load and paste a bitmap"


My comments were addressed to those.

That is what Ortu was telling you in the first place:

Quote: "or if you are using get image from the bitmap, check the texture flag."

Hello Green Gandalf:

Yes, but he didn't say how it should be set, then Fallout said to set it to 0.

Indeed he did - but there were only four values to try and there is a clue in the Help file:

Quote: "Texture Flag

Integer
A zero will treat the image as a texture and one will preserve pixel perfect quality, two will load as a cubemap texture and three as a volume
"

This is what happens when you don't have the help file to hand for reference. I didn't have DBP on the machine I replied on, so I tried to help from memory, and my memory ain't what it used to be! I thought it was 0 for "don't treat as texture". Sorry for the confusion. Glad you got your problem sorted.

Hello Fallout:

No biggie - I would have assumed the same thing (and it makes more sense that it would be 0 from a design standpoint - i.e. 0=don't do anything, other numbers=various compression formats).

Yes, I'm inclined to agree. DBPro is like that at times.

Yes, some of the set object indexes are backwards as well.
