IrfanPaint Support Thread

[Bhikkhu Pesala]

Someone just made the interesting observation that if you cut and paste a selection within a low colour image, the number of colours always increases to 16.7 million. Can IrfanPaint do anything to work around that with its selection tool? One could use the Clone Tool instead, but cut and paste is sometimes quicker.

Automatic conversion by IrfanView

Agree. Even a 1 bit picture (b/w) transforms to an 8 bit picture after pasting an 8 bits scrap. With of without using IrfanPaint. I always took this for granted and converted the picture afterwards. In my opinion this behaviour is the logical result of such a past action. When convering a 24 bits color picture to grayscale, it gets the logical 8 bits. To enlarge it to 24 bits is possible in IrfanView. Photoshop is the only program I know within one can remove the colors without automaticly reducing the bit size.

I agree, that with some modulations it's quite unpredictable if a bitmap stays in the same resolution or not.

I don't take the change for granted, it doesn't happen in other programs. MSPaint set my expectations in many ways. It is very underrated. It is also hell with an antique junk computer with a dying monitor - LOL - I have fond memories.

You can remove color in IrfanView without changing bit size, by reducing the saturation in the color adjust dialog.

The clone tool does not alter the color depth, so it would serve, but a selection can be more accurate. Must be a way to do it....

I had a nice dream about layers in IV. I'm always dreaming computer stuff

I copied the whole irfanview folder with all plugins and the german irfanpaint language file (did not installed it)

Irfanpaint complains about not found language file?

Do you check for the language file folder by a registry key?

[MItaly]

IrfanPaint do not use the registry, if you set IrfanView to use its German language file IrfanPaint will use its German language file (if available).

[flizebogen]

My mistake.

The version in the language file did not fit. After correcting it everythings works as expected.

Hallo.

At first, thank you for this plugin

At second, please, tell me, what I'm doing wrong:

I open small picture (2 colours) and then I open irfanPaint - I need change color. If I click on Color panel, I get panel with only few colours whith I cannot change - but I need other color (for example red).



But, if I open another picture, complexly and with more colours, I can use "standard" color panel and I can choose every colour what I need.

Its same with stable or develop version.

Please, explain me that "hidden" puprose of that "light" color panel.

Thank you, MartinezZ

If you are working on an paletted images the "light" panel is shown, and it shows all the colors available in the current image; if you are working on a 24bpp image, the normal color selection dialog is shown, since every color is available in 24bpp images. If you opened a paletted image but you want to use all the colors just increase the color depth (Image->Increase color depth...->select "16.7 million colors (24 BPP)"->OK).

[MartinezZ]

Ehm, I'm feel like... little stupid now Its logical. Thank you!

[matera]

It can be hard to know at a glance what the color depth is.

No problem, it's actually one of the more asked questions; if and when I'll write the FAQs this will be the first .

[Sjef]

Look into the menu Image»Palette to see the palette which is ‘build in’ into your image file. That is the color range the viewer (and the plugin) can work on.

[Bhikkhu Pesala]

It can be hard to know at a glance what the color depth is.

Look at the Status Line.

[MartinezZ]

Yes, thank you
